拥塞网络中连接时延和请求接纳率是一对矛盾。该文在现有分布式QoS路由算法的基础上,提出一种兼顾二者的改进算法。在中间节点转发请求包时,根据累计时延进行转发测试,减少了通信复杂度。在目的节点,根据一定策略从可行路径中选择最优路径发回应答。计算机模拟显示,该算法在拥塞网络中有较低的连接时延和较高的请求接纳率。
Congestion in the network connection delay and request acceptance rate is a contradiction. Based on the existing distributed QoS routing algorithms, this paper proposes an improved algorithm that takes into account both of them. When the intermediate node forwards the request packet, it forwards the test according to the accumulated delay, reducing the communication complexity. In the destination node, according to a certain strategy from the feasible path to choose the best path to send back a reply. Computer simulation shows that this algorithm has lower connection latency and higher request acceptance rate in the congestion network.
