The Next Generation of IP
-Flow Routing
Course: Future Internet
presented by Nguyen D. Thang
The existing problem of traditional
IP routers

IP routers actually didn’t support
QoS due to the facts that they
only care about packets, don’t
have any state information of
individual flows

Some mechanisms on higher
layers (> network layer) have
been developed to solve this
problem: RSVP ( Resource
Reservation Protocol), DiffServ,
LDP( Label Distribution Protocol)…

The Next Generation of IP Router:
This router can store and manage
the state information of data
flows.
What we need to consider to
implement flow routers ?
 Mixing packet and flow IP routers
 Error Recovery
 Integrate with existing network
protocol (e.g. Mobile IP )
 Intelligent flow managements
