Outline of the talk

The current Internet? Next Step? Service Architecture Router programmability Programmable edge device as a service

platform – its architecture Some applications About ARN

Current Internet

Optical(Scalable bandwidth)

Wireless Internet(Mobility, Location)

ConvergentIP

(Connectivity)

Serves well as a connectivity infrastructure

Does not handle mobility well

Does not possess adequate intelligence to deal with bandwidth

Internet – Where do we go from here?

Next Generation Networks:

Adapt to people, not the other way around!

•Services

•Services on-demand

•Mobility

•Resource Sharing

What we need is a service architecture

Programmable Service Platform

Internet Service Architecture – Programmable Service Platform

• Can introduce services on-demand• Can compose/negotiate end-to-end services• Can allocate resources (computing & storage)• Provide strong security• Can address mismatches

How are we composing the next generation Internet?

Service Architecture instead of Connectivity Architecture

Composing end-to-end services by negotiation

Deploying Optical Agility with Programmability and Scalability properties

Packet Processing in a traditional IP Router

Look at the destination address Identify routing-table entries

for a forwarding path Select the best match using

longest prefix matching for the IP address

Send the packet out to the output queue for the correct outgoing interface.

IP Packet

1. Check IP Dest. Addr

2. Routing Table Lookup

3. Select Forwarding Path

4. Send packet to output Q

control plane and in the data forwarding plane without adding software in the data path
