Peering at the Content Layer

Bruce Davie
Nicira Networks

About the talk:
The successful growth of the Internet can be attributed to many things, but one of the key ingredients was the concept of autonomous systems (ASes) and the protocols that enable peering among ASes. Peering at the IP layer allowed each AS to evolve somewhat independently and created economic opportunities for ISPs. In recent years, as more and more service providers have deployed content delivery infrastructure, there has been a growing interest in the interconnection of Content Distribution Networks (CDNs). We can think of this as peering at the content layer, as opposed to the traditional IP-layer peering. This has the potential to provide many similar benefits to traditional peering, as well as some new advantages. CDN peering offers more control over the routing of content and improves the efficiency of the overall system through better caching of popular content. This talk will present some recent work on the interconnection of CDNs including a look at some trials involving several large ISPs.
