摘要：

This paper proposes a unicast mechanism for rate adaptation at receivers called RAAR. It can be used to transport multimedia data traffic. Neither TCP nor UDP can be used by multimedia traffic, because the TCP reduces the sending rate in half in response to a single packet drop and UDP has no congestion control mechanism. RAAR ameliorates GAIMD in receiver ends and has good smoothness of sending rate and fairness with competing TCP flows. RAAR is simple to implement. Simulations show that the performance of RAAR is better than those of TFRC obviously. RAAR is also a promising avenue of development for congestion control of multicast multimedia traffic, because it is not a per-packet acknowledgement mechanism and is implemented in receiver ends.
