UDP对QQ来说太重要了。 UDP和TCP是同一个层上的协议,都是通过IP层进行数据。。。 算啦,不扯这些了。 UDP针对的是不需要保证数据一定传输到的一种协议。因为IP 本身是会被随意丢弃的,所以TCP为确保数据可靠,会消耗大量的 资源,而且Socket架上去以后会出于保持链接的一种结构。 QQ本身不保持链接,数据是否可靠自己去验证,而且QQ里的数据 都是小包,尤其适应UDP的结构。最后对于multicast来说,UDP 是唯一可行的降低网络带宽负担的协议

java语言开发的P2P流媒体系统,“Stream-2-Stream implements multicast+, a next generation streaming protocol. multicast+ is more efficient and requires less bandwidth than direct streaming (e.g. shoutcast/icecast). Stream-2-Stream (abbreviated "s2s" or "S2S") stations have no user limit stations can be set up without paying a fortune for bandwidth. Stream-2-Stream saves bandwidth by passing streams from one peer to another through multicast and unicast p2p, rather than everyone getting a stream from one central server (Shoutcast/Icecast). ”更多:http://s2s.sourceforge.net/about.php
