Title: Software-defined Multicast: Using OpenFlow to Push Overlay Streams
into the Underlay

Abstract

Today, an increasing number of live video streaming
services are provided over the Internet. To deliver these video
streams in a scalable and cost-efficient manner, approaches such
as Content Delivery Networks have been proposed. They usually
end at the edge of the residential Internet Service Provider
(ISP) networks. From the edge, they have to transport individual
unicast streams to the clients. Peer-to-peer (P2P) streaming
mechanisms promise to further improve the situation for content
providers by reducing the load on their infrastructure by using
the client devices in the distribution process. While this is
promising for the content provider, in both cases the costs stay
with the ISPs. They have to carry a potentially large number
of individual streams with the same content to their clients. To
address this problem, in this talk the OpenFlow-based
cross-layer approach entitled Software-defined Multicast (SDM) is
proposed that allows ISPs to offer a service with support for traffic
originating from outside their own network.
