摘　　要：为了平衡通信协议的自适应性和性能,提出一种避免拥塞的片上网络通信协议.该通信协议采用区分服务和自适应路由算法,区分服务提供不同等级数据流的质量保证型服务,自适应路由算法是一种避免拥塞的无死锁路由算法.通过OPNETM odeler建模仿真,结果表明该协议极大地改善了网络的平均链路利用率和端到端延迟.Communication protocols should establish a balance between adaptive and performance in network on chips. This paper proposes an on-chip congestion avoidance communication protocol. And the study focusing on the differentiated services and adaptive routing algorithm, differentiated services provide different levels of service quality for different data streams, and the adaptive routing algorithm is a deadlock-free routing algorithm, which based on congestion avoidance. According to the OPNET Modeler simulation model, the results show that the agreement have a significant improvement on both end to end delay and link utilization in the network.
