Content Based Traffic Engineering in Software Defined Information Centric Networks

Abhishek Chanda, Cedric Westphal and Dipankar Raychaudhuri

This paper describes Information Centric Networks over Software Defined Networks. Applications are

  1. Traffic engineering in ICN

  2. Content based firewall

  3. Network wide cache management

Per-flow granularity not sufficient for content based routing. Some routing can be done based on content length. Meta-data is extracted from ICN interest and data packets. This can be via

  1. Network layer extraction of content length – classified into mouse/ elephant.

  2. Application layer – reading of http headers gets content length. Just knowing length allows various engineering as described above but only based on length.

The engineering problem describes involves working out where to place a flow of length F given background traffic and capacities of all links.
