“…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.

Transport network architects have had a different vision

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

NETWORKS


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

 Optical interface integration

 Operational integration of control plane and service/network management


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.

Integrated Multi-Layer Control

Optical tunnels via control plane signaling, “outer” tunnels

Ethernet

Clients see port-based EVC interfaces

Ethernet tunnels via control plane signaling, “inner” tunnels


GMPLS Interworking

= 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

SWITCH


“…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
