Challenge - Consolidate Four Dedicated
Functions
ƒ Video distribution
Aging servers
High WAN bandwidth consumption
Decentralized management for 140 servers
Labor-intensive replication of videos for positioning on all
servers
IP/TV® limited to Windows, not Linux, because of support
burden
ƒ Software distribution
Inability to assign priority to urgent files

Challenge - Consolidate Four Dedicated
Functions (Contd.)
ƒ Content caching
No support for application caching, which increases productivity
ƒ HTTP worm and virus blocking
High costs of separate cache engine architecture and support
structure

Solution WCCP Process at Tier 3
ƒ Local Router intercepts
client request for content
ƒ Router redirects
appropriate traffic to the
local content engine
through WCCP.
ƒ Content engine requests
the content from the
remote origin server.

Solution WCCP Process at Tier 3
(Contd.)
ƒ Origin server serves the content directly to the local
content engine, where it is cached to disk.
ƒ When enough data has been received to begin serving,
the employee begins receiving it through the content
engine cache.
ƒ Subsequent requests for the same content, from any
user in the same facility, are also served from the
cache.

Solution - Remote Access Unicast

Concentrator
IPsec VPN
Tunnels
ƒ
Remote access VPN links cannot support multicast, and
the VPN concentrator splits the multicast traffic into live
unicast streams sent along each individual secure VPN
tunnel across the Internet.

Solution - Content Policies
Cisco® IT uses GUI to specify:
ƒ Bandwidth that the Cisco ACNS network is allocated on
the WAN
Live streaming media content allowed at any time of the day
More content and larger files allowed over the WAN at night
ƒ Content pushed to specific Tier 2 content engines
Some content is location-specific, such as content written in
different languages
ƒ Content freshness, or “time to live”
Directs content engines to delete content that has passed its
expiration date

Results - ROI in EMEA and Worldwide
(Contd.)
ƒ Server replacement cost avoidance
One-time savings of approximately $140,000 by eliminating the
need to replace 140 aging servers
ƒ Reduced content replication costs
ƒ Delayed bandwidth upgrade (estimated $500,000
savings globally)
ƒ Reduced costs for virus and worm remediation
(estimated $500,000 savings per year)
ƒ Increased availability by offloading central Web servers
(estimated $150,000 savings per year)

More Results
ƒ Reduced infrastructure management burden
Pushes configurations to selected group of content engines,
eliminating the need to configure one by one
ƒ Enhanced software distribution
Automates the replication process
Mitigates the bandwidth drain of large file distribution
Distributing a 420 MB Microsoft Office 2003 update individually
to 34,000 employees = 12 terabytes; sending it to 230 sites for
local distribution = 70 gigabytes
Distributing updated virus definition files to 34,000 employees
within minutes

More Results (Contd.)
ƒ HTTP worm and virus filtering
ƒ Application acceleration through caching
Reduces time that sales personnel spend connected to the esales portal from 3 hours per week to 2, a 35-percent reduction
Page load times increased – as much as 10x

Next Steps
ƒ Standardize device management to the point where it
can be outsourced
ƒ Extend Cisco® ACNS network to partner sites
ƒ Extend Cisco ACNS network to EBCs so that
presenters can schedule videos using the ACNS
interface
ƒ Distribute new software being developed in support of
Cisco IT’s new Oracle 11i ERP upgrade
ƒ Use satellite rather than terrestrial links for distribution
of content to Tier 2 sites
ƒ Publish all VoD files in both Windows Media and Real
formats to support Linux as well as Windows clients
