—————————————————————————————————————————————————— URPipe：不可靠模式双向管道 RPipe：可靠模式双向管道 mcast：组播(JxtaMulticastSocket) socket：基于流的接口（JxtaServerSocket/JxtaSocket，对本项目影响不大，由于时间关系，没有进行测试） 单位：毫秒；表格中的数值是RTT(Round Trip Time)往返时间，计算单程时间减半。 Test11是在PC1上的两进程互传，可以近似看做是在同一个局域网中。 其中URPipe的时间明显小于RPipe的时间，但比起Tcp和Udp仍然较大。 比较出乎意料的是mcast，其RTT值将近3秒，这个以前没有注意过。 Test12是从PC1向PC2发送消息，然后PC2在收到消息后马上将消息返回给PC1所消耗的时间。测试结果与Test11基本相同，除了各项数值普遍要大一些。 另外一个现象值得注意： 在PC1上，对于双向管道，当使用连续密集发送100消息，延迟会逐渐增大到1s以上而使用不可靠模式时，丢包现象比较严重，发了100个消息，最后只收到40个消息。 在PC2上，对于双向管道，当使用连续密集发送100消息，延迟只增大到100ms级；而且使用不可靠模式时，基本没有丢包现象。 看来我的电脑确实该扔了。。。 —————————————————————————————————————————————————— 感觉延迟虽然会对系统有一定影响，但还不是最关键的因素，对于流媒体来说，一定程度的延迟是可以接受的。 上面的测试结果可以作为参考，由于测试过程比较随意，因此不是很精确。 本来想多次发消息取平均值可能更科学一些，但在PC1上连续发消息很多次后，延迟很快增长到若干秒，感觉失去了测试的意义，就此作罢。。。 —————————————————————————————————————————————————— 感觉延迟虽然会对系统有一定影响，但还不是最关键的因素，对于流媒体来说，一定程度的延迟是可以接受的。
