that’s backed by world-class customer support.
Internet Connectivity
A Fast, Reliable Connection to the Internet
As one of only a few fully peered facilities-based, Tier 1 Internet
backbone providers in the United States, XO has hundreds of private
peering arrangements in most major metropolitan areas at speeds of
up to 10 Gigabits per second. By routing around congested public
peering points, these private peering relationships with virtually all
major Internet providers give you reliable connectivity and the best
possible speed and throughput. That’s how XO delivers your data to its
destination securely, reliably, and along the fastest route possible.
And, with self-healing SONET metro fiber rings and meshed
SuperPOP network architecture, XO provides redundancy and high
availability to all its customers.
The XO High Capacity multiple 10 Gigabit IP backbone employs an
advanced design providing high availability and throughput using
technologies such as SONET and network MPLS. Each market
attaches into the 10 Gigabit core with uplinks at speeds of up to 10
Gigabits. This ensures that your traffic is carried on a high
performance, low-latency network with minimum delays across the
backbone. XO maintains the highest level of interconnection to other
Internet Service Providers (ISPs), as well as to multiple network
exchange points, so that your Internet traffic is delivered reliably and

efficiently. XO utilizes high-throughput, private peering connections to
transfer your data from the XO network to the network of other ISPs.
Private peering provides direct connectivity to other ISPs and avoids
any problems you may have seen with ISPs who only have
connectivity at public peering exchanges or NAPs.
There are multiple paths for your data to traverse within the XO
network. This redundancy ensures that your data can reliably reach its
destination. There is automatic re-routing of IP traffic in the event of a
major outage. Also, XO state-of-the-art Operations Desk
Representatives perform proactive 24x7 network monitoring and
technical support.
Point-to-Point
Point-to-point means that the Internet access product delivered to XO
customers under the Dedicated Internet Access service is a dedicated
or non-shared, high-speed product. This means that the entire
telecommunications circuit that connects the customer's premises to
the XO network is fully dedicated to the customer. It is not shared with
any other customer.

You may be looking for greater bandwidth capacity to your premises
routers than can be accommodated on a single T1 access facility.
However, you may not have capacity utilization to be able to justify the
expense of a T3 access facility, or your budget may prevent you from
obtaining T3 service. Rather, you may be primarily interested in
providing enough bandwidth to your users and/or customers in an
efficient manner.
The XO Multi-T1 Internet Access solution is intended for you if you
require increased bandwidth from the Internet but do not want the
higher cost of a T3 circuit. Our current NxT1 solution is based on two,
three or four T1s connected to an XO provided router configured as
MLPPP for contiguous bandwidth across the multiple T1 circuits. The
bandwidth capacity obtained through such a configuration is 3, 4.5 or 6
Mbps. All T1s will connect to a single CPE router and to a single
Access Router port on the XO Internet Network edge.
The XO Ethernet over T1 Access solution is intended for you if you
require increased bandwidth from the Internet. Our Ethernet over T1
solution is based on two, three or four T1s connected to an XO
provided router with physically configured contiguous bandwidth
across the multiple T1 circuits. The bandwidth capacity obtained
through such a configuration is 3, 4.5 or 6 Mbps. All T1s will connect to
a single CPE router and to a single Access Router port through a
switch on the XO Internet Network edge.

Internet Access via Ethernet
XO’s High Speed DIA product suite offers customers the ability to
scale their bandwidth by purchasing burstable Internet Access via
Ethernet. Large customers who require upwards of 100 Mbps can
choose to purchase XO High Speed DIA via Ethernet, Fast Ethernet,
and Gigabit Ethernet. XO’s fiber-rich metro assets allow XO to provide
Internet Access on its own facilities to customer premises, reducing
installation and troubleshooting intervals. Additionally, XO can connect
your premises to the XO network over aggregated copper, T1 or T3
loops with specialized equipment to allow for 10, 44 and 87 Mbps
Ethernet connections to be created. The burstable price plans allow
customers to commit to a specific bandwidth speed, while
simultaneously allowing customers to use up to the full port speed, of
10 Mbps, 100 Mbps, 1,000 Mbps or 10,000 Mbps.
XO also rents routers for the 10, 15 and 20 Mbps and 100 Mbps
service arrangements at reasonable monthly rates. Available devices
are the 2951 and 3925 from Cisco for the 100Mbps service and the
Adtran 3430, Cisco 2901 and the Juniper 100B for the 10, 15 and 20
Mbps services.

Do you need BGP?
What Is BGP and Do I Need It?
Today, many customers want or need to specify access and circuit
redundancy for their sites that are connected to the Internet. Border
Gateway Protocol (BGP) support for DIA routers addresses this
demand. XO supports customers who wish to implement redundant
Internet connections with XO and another provider, using BGP to
maintain reliable and efficient Internet access.
If you have high availability requirements, you want to assure that
there is no single point of failure between your location and the
locations your want to reach or the locations that need to reach you.
Furthermore, you may wish to leverage multiple connections to realize
additional benefits such as network load splitting and balancing.
BGP is an exterior gateway protocol (EGP) used to exchange routing
information between different autonomous systems (AS). This network
layer reachability information (NLRI) is maintained in a database on the
router, and exchanged with other routers; the NLRI is used to create a
graph of AS connectivity, which allows BGP to:
• remove routing loops,
• enforce policy decisions, and
• forward traffic to the shortest path at the AS level.
It is the protocol used to create the Internet backbone. The most basic
criteria establishing the need for BGP is a network with two (or more)
upstream provider connections where the customer wishes to
announce his network address space to the Internet through these
providers for the purpose of provider redundancy and / or shortest path
routing.
When more than one link connects your network cloud and another
network, the links can be used for various traffic purposes. Those links
may be used as an additional primary link, a backup link, or for load
splitting (i.e., a primary link for certain networks and a backup for
others.) In certain cases involving links from a single access router,
the links may be used to achieve load balancing. By adding additional
links in combination with the appropriate routing configuration,
redundancy at the IP layer can be obtained. XO provides BGP support
for connection to multiple redundant providers in the direction from XO
to you, and is supported at all access speeds.
Single provider homed networks do not usually need BGP, and can
achieve circuit redundancy or load sharing without running BGP.

10
The decision to use BGP is best discussed with an XO Sales Engineer
because it depends on the customer network design and needs of the
customer.
Utilizing BGP
XO Announcement Options
Customers utilizing BGP have options as to what routes we will send
them; these options consist of:
• Full Internet Routes – All routes XO receives from its peers,
customers and originating from our own network.
• XO Only Routes – Routes only originated by XO or received from
our BGP customers.
• Default Only – A single default route.
A customer who wishes to receive a default route in addition to either
full XO routes or full Internet routes needs to request it through the
order process. For these outbound announcements to the customer,
XO sends Multi-Exit Discriminator (MED) attribute and unaltered
community attributes. These MEDs help give the customer a better
routing decision, which reflects those destinations on the XO network
that may be closer to the POP where the customer is connected. XO
sets MED to the following values:
• “1” for 2828 aggregates
• “2” for routes tagged with the local market community, and
• “3” for everything else.
Customer Announcement Restrictions
Customers are limited in what XO will accept as valid routes. Any noncompliant routes are discarded. Customers should strictly filter their
announced routes to only those authorized by XO, rather than depend
on XO customer controls.
The following limitations are applied to XO BGP customer
announcements:
• Prefix Limits – Every prefix should either be assigned by XO
provisioning / pre-sales / IP admin group or a registry (ARIN, RIPE,
APNIC, etc.) directly. If the block is out of another ISP's aggregate, our
Best Current Practice requires a letter or email from a representative of
that ISP, authorizing XO to accept and re-advertise the prefix(es) from
the customer's AS / connection. XO does not accept prefixes shorter
than a /8 or longer than a /24.
© Copyright 5/15/2012. XO Communications, LLC. All rights reserved. XO, the XO design logo, and all related
marks are trademarks of XO Communications, LLC. All other trademarks are property of their respective owners.
11
• AS-Path Limits – XO will only accept routes from the customer AS
and any downstream AS using that customer network for transit
services. XO rejects any route not explicitly allowed. Direct request for
addition of a customer downstream AS and / or prefix needs to be
made via an email to [email protected].
• Community Attribute – Customer announcement communities are
limited to the two “well known” values of “no-export” and “no-advertise”.
All other communities – with the exception of customer signaled,
private communities (described further in this document) – are deleted
from the update. Other than the deletion of the unauthorized
community, the routes are treated like any normal advertisement.
While XO filters on customer-announced routes, it is the responsibility
of the customer to ensure they are only sending approved routes. XO
reserves the right to protect its network from both authorized and
unauthorized announcements that may result in any negative impact to
the XO network and the Internet at large. These actions may include –
but are not limited to – maximum-prefix peer shut down mechanisms,
route filtering or peer administrative shut down until the problem is
corrected.
XO Community Controls:
Customers can control their routing through a variety of methods.
Some of these are special community based controls implemented by
XO, while others are standard BGP controls.
- Local-Preference
For our BGP customers, XO has implemented a powerful, flexible
system whereby we allow our customers to control – via predefined
communities – the XO treatment of their announcements. These
communities control XO local-preference (local-pref) of customerannounced routes within our network.
The most powerful attribute is local-preference.
In BGP, the higher the local-preference, the more preferred the route
on the network. This affects XO backbone route selection only, and not
the route selection made by XO peers and customers, because local
preference is non-transitive. This means it does not get passed beyond
the XO network. The customer has a range of six local-preferences to
which they can set their routes.

12
The following table details the local-prefs, including the actual value,
the community accepted from the customer to set the local-pref, and a
description of what that local-pref will do in the network.
- AS-Path Controls
The next attribute that customers can use to control their routing is via
AS path length.
The most common use of AS-path prepending is in a direct peering
route-map on the customer end where they can prepend their own AS
to their routes as they announce the routes to AS2828. XO also
accepts communities that prepend AS 2828 either one time or three
times to the route as it leaves the 2828 network.
Currently, there are three general groups on which the customer can
set 2828 prepends:

marks are trademarks of XO Communications, LLC. All other trademarks are property of their respective owners.
13
- Origin Attribute
Another standard option for customers to control XO treatment of their
advertisements involves the use of the origin attribute. XO does not
alter origin code on routes customers send us. Routes set with the IGP
origin code are more preferred than routes tagged with the origin EGP
code, which are more preferred than origin-Incomplete routes.
- DoS Discard Community
XO provides a mechanism allowing customers to trigger the XO
backbone to discard all traffic entering the XO network from external
sources destined for any routes specifically announced by a BGP
customer with a special community.
- MED Controls
Another standard option for customers to control XO treatment of their
advertisements involves the use of the MED attribute.
The lower the MED attribute set on a route, the more preferred the
route. XO currently accepts MED from its customers. For more details
on (Cisco) BGP path selection and attributes, see Cisco's Web site.

14
NAT – Network Address
Translation
This feature allows you to use private addresses from your internal
network and still connect to the Internet via a T1 or multiple T1. To do
so, XO allocates a block of registered XO addresses to you for use on
your XO-managed CPE router that performs Network Address
Translation (NAT).
NAT is used on the CPE router to provide you additional addressing
flexibility through use of “private” IP addresses, allow interconnection
with other internal networks that may already have their own
addresses, and allow you to use a smaller number public IP addresses
on your Internet connection.
If you have implemented a private addressing scheme throughout your
networks, routing over public networks with such an addressing
scheme is not possible without the use of tunneling or other scheme.
The Network Address Translation feature solves this problem. NAT
converts your inside addressing schemes into the registered
addresses prior to forwarding the packets to the public Internet. The
translation is fully compatible with standard routing functionality and
features.
NAT allows you to utilize public network infrastructure for transport and
not change the existing IP addressing scheme (using public or private
IP addresses) in your enterprise.

Network Overview and Map
The XO IP network consists of three main network elements; (1)
Peering infrastructure to the rest of the Internet, (2) a core 10 Gigabit
IP backbone and (3) DIA and DSL access POPs in the local markets.
The figure below shows the XO IP Network, including peering
interconnections, the 10 Gigabit IP backbone and local market DIA
POPs

16
The XO 10 Gigabit IP Backbone
The core of the North American XO IP backbone is a mesh of multiple
10 Gigabit circuits, interconnecting peering, Data Centers, and local
DIA POPs in each market. XO has implemented a multiple 10 Gigabit
IP backbone that runs completely across its own Inter-city facilities.
Using a mesh of physically diverse 10 Gigabit circuits, this backbone
interconnects local market DIA points of presence (POPs) with multiple
high-capacity peering interconnections. Each DIA POP is connected
into the 10 Gigabit IP backbone with OC-48c or 10 Gigabit circuits,
depending on traffic requirements.
This network design delivers maximum end-to-end throughput as well
as providing high levels of protection and redundancy. The XO 10
Gigabit backbone utilizes an advanced IP design, ensuring scalability
to accommodate our growth in the future as well as the added benefit
of having no single IP point of failure beyond the customers' port. And
since the XO 10 Gigabit backbone and market connections run end-toend across XO facilities, XO can quickly resolve any problems that
may occur without any delays.
Peering Infrastructure
As one of the few facilities-based Tier 1 network backbone providers in
the U.S., XO has substantial private peering arrangements in many
metropolitan areas at speeds of up to 10 Gbps. As a Tier 1 Internet
provider, XO is constantly improving its peering infrastructure to benefit
our customers. Those advantages include:
Multiple and geographically redundant dedicated connections to other
Tier 1 Internet backbones. Dedicated and private connections mean that
traffic crosses the XO backbone and the peering partner's backbone
without transit through another ISP. Customers benefit because data
packets to and from the peered networks reach their end destination
quickly and with lower risk of packet loss.
XO peering relationships are monitored and maintained 24x7.
Quality control of the XO network is high as we do not have to rely on
other ISP networks for Internet connectivity.
DIA Points of Presence (POPs) in Markets
XO currently offers Dedicated Internet Access connections via 36
Metro POPs in 31 markets. All DIA markets are connected to the
closest 10 Gigabit IP Core Node; dual uplinks are provided from each
Metro market into the closest Inter-city core node using OC-48 or 10
Gigabit links.

Usage Based DIA Reporting
XO provides Usage billed DIA for Burstable Ethernet 100, Gigabit
Ethernet and DS3 Services. As customer businesses have evolved,
their need for data services have changed from easily predictable
static usage patterns to more dynamic usage patterns with seasonable
and time of day bandwidth peaks. The more sophisticated a customer
becomes and the more complex their business model gets, the more
the customer expects to pay for usage, rather than an entire “big pipe”
which might only be used at full capacity a couple of hours per
day/week/month.
In summary, usage based billing for DIA can be defined as follows:
Customers will have access to a full port speed connection but
they only pay for their actual commitment plus any usage seen
above the commitment up to the full port speed.
Usage Billing is calculated based on the 95th percentile rule
- Data transmissions are sampled in 5 minutes intervals
- Monthly samples are ranked from largest to smallest for
inbound or outbound and the larger amount is used
- The top 5% of samples are discarded
- Customer is billed based on the remaining 95th
percentile of usage
All usage based customers will have MRTG enabled on their XO port.
MRTG will measure the bidirectional usage on the port every 5
minutes. This usage info is then put in a graph showing both inbound
and outbound traffic. MRTG stats are a reflection of the actual traffic on
the XO router where MRTG stats are collected.
On the chart below the green zone, “inbound”, is traffic that is coming towards
the XO router from the customer. The blue line, “outbound”, is traffic that
leaves the XO router towards the customer.

XO Usage Reporting
XO Usage Reporting provides several formats for new or existing
customers to view performance statistics, from average monthly
latency and packet loss metrics for the Core IP network to near realtime, circuit utilization rates for a customer’s DIA circuit(s). Additional
formats include graphical displays for daily, weekly and monthly
statistics throughout a calendar year.
Overview
The XO Usage Reporting system found at XOStats allows you to track
and monitor your web usage (throughput) by circuit and port. This
information allows you troubleshoot, plan future capacity requirements,
and help track usage spikes during peak usage. In addition, the tool
can help track spikes during peak periods. The graphs, which are autoscaled according to the range of output, are based on a linear scale.
For your convenience, you can view the data for each circuit by day,
week, or month.
Introduction to XO Usage Reporting

Downloading Data and CSV Files
A CSV file is a comma delimited text file. It can be opened by
numerous applications including almost all text editors, spreadsheets,
and web browser. This format should be easy to import and use in your
own applications or documents. You will notice in CSV files, the
heading 'inbytes'; this is the number of bytes received during the given
time period. 'Outbytes' is the number of bytes sent during the given
time period. If the program that you are using fails to display the first
'date' field successfully then expand the width of the column. It should
then successfully display.

poll intervals. Here is an example of such a file that in this case is
being displayed in Internet Explorer
All dates are in listed as "month/day/year" format.
If you press the "Graph all Lines" link, all circuits for the chosen day will
be displayed. "Graph Just this Line" all but the chosen graph will
disappear. "Return to List" will bring you back to the starting page.

XO DIA Service Level
Agreements
XO DIA and Combined Services are backed by specific service level
guarantees. If these guarantees are not met, the credit set forth below
will be issued if requested by the customer and verified by XO,
following the procedures outlined below. The total of all credits
provided under this SLA are limited to the monthly recurring charges
for the affected DIA or Combined Services for the affected month of
service.
Network Availability Guarantee - 100%
The XO IP Network, as defined in this section, is guaranteed to be
available and capable of forwarding IP packets 100% of the time, as
averaged over a calendar month. The XO IP network includes the
customer's access port (the port on the XO aggregation router upon
which the customer's circuit terminates) and the XO IP backbone
network. The XO IP backbone network includes XO owned and
controlled routers and circuits (including any transit connections). The
XO Network Availability guarantee does not include the local access
circuit (e.g. local loop), Customer Premises Equipment (router or CPE)
or Customer's Local Area Network (LAN), scheduled maintenance
events, network events on redundant network elements, customer
caused outages or disruptions, interconnections to or from and
connectivity within other Internet Service Provider (ISP) networks, and
force major events (as defined in the relevant service contract).
If the Network Availability guarantee is not met in a calendar month,
the customer will receive a credit of 1/30th of the monthly recurring
charge (MRC) for that month for each full hour of outage in excess of
the 100% guaranteed under this SLA. Limits on the credit and the
reporting procedures are detailed below.
Latency Guarantee (55 Milliseconds Round Trip)
The XO IP backbone network (as defined in the previous section) is
guaranteed to have an average round trip packet transit time within the
XO IP backbone network over a calendar month of 55ms or less. The
average latency is measured as the average of 15-minute samples
across the XO IP backbone network taken throughout the month. The

XO Latency guarantee does not include the local access circuit (e.g.
local loop), CPE or Customer's LAN, scheduled maintenance events,
customer caused outages or disruptions, interconnections to or from
and connectivity within other ISP networks, and force major events (as
defined in the relevant service contract).
If the Latency guarantee is not met in a calendar month, the customer
will receive a credit of 1/30th of the monthly recurring charge (MRC) for
that month for each full 1ms above the 55ms average maximum
guaranteed under this SLA. Limits on the credit and the reporting
procedures are detailed below.
Packet Loss
Maximum average packet loss of 1 percent during any calendar month.
Jitter Measurement
No greater than 1 millisecond (Ms) average during any calendar
month.
Credit Limits and Reporting Procedures
To receive credits, the customer must contact XO Customer Care
within two business days at 1-888-575-6398 for XOptions and Voice
services, and at 1-888-699-6398 for Data and Web services. The
customer must provide information supporting the claim of a SLA
violation such as PING and/or traceroute output taken at the time of
the occurrence, which demonstrates the problem(s) being reported.
XO will take all measures it deems appropriate to Investigate reported
outages. Determination of credits due pursuant to this SLA will be
made solely by XO.
Total credits under this SLA are limited to the monthly recurring charge
for the affected DIA service or Combined Service for the month in
which the service does not meet the guarantees.
