CalREN Architecture
 Dark fiber backbone throughout California
 Cisco DWDM optronics support up to 32 waves
on each segment
 100GE path Los Angeles – Bay Area – Seattle in
partnership with Pacific Northwest GigaPOP and
Internet2

Multiple L2/L3 Networks
 CalREN/DC – “Production” network. California-wide
intranet with transport to commodity Internet.
Designed for high availability with sufficient
capacity for current/projected needs
 CalREN/HPR – High-Performance Research network.
Layer-3 with connectivity to NRNs (Internet2, NLR,
ESnet, DREN, etc.) and international networks.
Designed for high performance with ample
headroom for on-demand experiments/demos.
State-wide Science DMZ.
 CalREN/HPR-L2 – Layer-2 network with connectivity
to Internet2 ION/AL2S, NLR FrameNet, Pacific Wave,
WRN

Campus Access
 Access via dark fiber, supplemented where
needed for redundancy with telco circuits
 10GE common though not ubiquitous
 100GE being delivered to several R1s in the next
several months
 Exception to normal last-mile pricing model to
encourage early adoption
 Will provide 100GE L2 access to Internet2, ESnet

COTN
 California OpenFlow Testbed Network
 Funded via GENI Solicitation 3, which sought to
encourage OpenFlow deployment into the RONs
 10GE ring with switches in LA, Sunnyvale,
Sacramento, with GENI stack. GENI rack to be
installed in by summer.
 Campus access via HPR-L2 or direct connection
 Brocade MLX-E switches chosen for HPR
compatibility

Challenges
 Excellent pricing and support from Brocade
 …for code that doesn’t quite work yet
 Brocade actively solicited guidance on desired
functionality (but at the time we didn’t know what
that was)
 First non-beta, non-NDA code received just prior to
GEC 14 (July 2012), lacked significant functionality
needed for planned demo with UCSC researchers
 Current code lacks ability to have simultaneous
L2/L3 flows; fix expected soon
 Breaks ARP

We Built It And They Haven’t
Come (Yet)
 Both HPR-L2 and COTN have had slow uptake
rates
 The networking effect (nobody’s connected
because there’s nobody to connect to because
nobody’s connected)
 Early levels of OpenFlow functionality
 Access cost (dedicated wave to HPR-L2 historically
an institutional cost)
 100GE pricing program should address much of
this
 Please talk to us if you have applications that
could make use of this infrastructure
