Multicast congestion control for content distribution
Óscar Martínez, Carlos Enrique Palau · 2009
Content Delivery Networks (CDNs) provide an efficient support for serving http and streaming media content while minimizing the network impact of content delivery as well as overcoming the server overload problem. Not too much research effort has been placed in the analysis of the access network and the impact and benefits of multicast. This paper proposes an innovative real-time protocol offering an hybrid congestion control algorithm called Scalable Reliable Multicast Stair Hybrid (SRMSH) which combines the benefits of TCP AIMD with Rate-based (STAIR) [2] for layered multicast with Scalable Reliable Multicast (SRM) [6] in order to offer loss recovery methods if receivers detect loss events. The mechanism has been simulated and implemented to proof its benefits.
