“…Big, fat, dumb pipes…” For nearly all of the last two decades, IP network architects have been asking the transport layer to provide big, fat dumb pipes.

Networking Realities
Cloud computing drives
ENTERPRISE NETWORKS
Three solid growth trends drive sustainable demand for our converged Optical+Ethernet transport solutions
“IPTV Service Revenue will grow from US$17.5
billion to US$46 billion in 2014.”
Multimedia Research Group, Inc. June 2010
Video content drives
CARRIER INFRASTRUCTURE
Mobile broadband drives
ETHERNET ACCESS
“Mobile market is booming — we expect 60% backhaul equipment market growth in 2009. …We see no letup
in the market…”
Infonetics Research, November 2009
“The industry is poised for strong growth through 2014,
when worldwide cloud services revenue is projected
to reach $148.8 billion.” Gartner, June 2010

Networking Realities
Cloud computing means
HIGHER SPEED CUSTOMER
INTERFACES
LOWER LATENCY NETWORKS
It’s time for a new level of integration between IP and transport
Video content means
HIGHER TOTAL NETOWRK
BANDWIDTH
Mobile broadband means
MORE DYNAMIC AND STOCHASTIC

Traditional networks Management silos enforce
operational separation, slowing reaction to traffic changes
Layer interconnection drives interface counts
Integrating Packet and Optical Networks
Operational simplification Flexible, reconfigurable optical layer

Agile Core Network Market Trends and Requirements
Cloud Computing Web 2.0 and Video
Rapid bandwidth demand increase Unpredictable traffic patterns
Increasing peak-to-average bandwidth demand
Agile Core Network
• Flexible traffic management at the lowest possible / best suited OSI layer
• Data Center and PoP consolidation support
• Multi-layer awareness
The Agile Optical Core provides more capacity, reach and flexibility; Network resources can be allocated on demand.

= GbE 1310nm to transponder = STM64 DWDM to ROADM
= 10/100 eth (fe0, eth0) = GRE tunnel = OSC
= RSVP-TE, OSPF-TE
" Control Plane " Optical tunnels setup via CP; label is Lambda " Ethernet tunnels also setup via CP; label is
VLAN tag " VLAN tag may change along service path, per
policy

“…Big, fat, smart pipes…” " Create a virtual mesh on DWDM layer
" PSC layer is realized as a fully meshed one-hop network.
" Eliminate transponders " Support DWDM optics directly on router " $2500 to $4500 savings for 10Gbps network interface depending on use of core or access
cards
" In existing organizations " Bring WDM efficiencies to the router teams
• DWDM interfaces directly on routers give access to the transport “pipes” available in the network " Remove intra-company lag to turning up new wavelengths for more efficient peering
• End-to-end Ethernet services can be provisioned across optical transport network by existing router teams
" Enable new “on demand” services

Agile Core Evolution
1. Control plane interworking " Provisioning & restoration " Link state statistics
2. Alien wavelength support " Colored interworking " Control plane support of alien wavelength
3. Fully integrated packet optical switching solution " Maximizes interfaces and operational efficiencies " Unified network management and control plane
