The results of simulation experiment show that the unreliable transmission path rate of the CCR becomes better than that of Dynamic Source Routing Protocol ( DSR ) with the increase of the network scale .

仿真实验表明，网络规模越大，协同通信路由算法 不 可靠传输路径比率越是优于动态源路由 协议。

UDP packet or user datagram : UDP is an unreliable connectionless protocol .

UDP包或用户数据报：UDP是 不 可靠、无连接的 协议。

Typically HTTP is an unreliable protocol to use for delivering Web service messages .

通常，HTTP不是用于传递Web服务消息的 可靠 协议。
