In this paper, we propose an efficient TCP-friendly traffic
control scheme for layered multicast with router assistance. The proposed
scheme is based on Network-based Layered Multicast (NLM), which dynamically
adjusts the traffic on each link at a router to ensure the high
quality data reception at the receivers as much as possible the network
allows. The proposed scheme enhances TCP-friendliness of NLM by improving
the traffic control granularity. The performance results show that
the proposed scheme yields better performance compared with the original
NLM and RLC, an end-to-end traffic control scheme for layered
multicast.
