Key Take-Aways

New usage patterns indicate connection-oriented behavior

Majority of metro and core traffic is “transit traffic”

General-purpose routers are too costly, power hungry

Packet handling bifurcating into two functions: 1. Specialized IP service processing (including routing)

2. Packet Transport (simple tandem switching)

File size

Work

Done

per

Packet

For majority of traffic, need

less overhead per packet Packet processing by a router

takes longer than frame

forwarding by a Layer-2 switch.

Use pre-determined path to

final destination to avoid

hop-by-hop lookups.
