webRTC支持点对点通讯,但是webRTC仍然需要服务端:  . 协调通讯过程中客户端之间需要交换元数据,    如一个客户端找到另一个客户端以及通知另一个客户端开始通讯.  . 需要处理NAT(网络地址转换)或防火墙,这是公网上通讯首要处理的问题.    所以我们需要了解服务端相关的知识:信令.Stun.trun.ice. 一.什么是信令 信令就是协调通讯的过程,为了建立一个webRTC的通讯过程,客户端需要交换如下信息:  . 会话控制信息,用来开始和结束通话,即开始视频.结束视频这些操作…
原题:  Turn the pokers       思路:假设正面为0,反面为1.牌就像这样 000000....... .考虑到假如可以实现最终反面个数为m, 牌共n张, 则这n张排任取m个为反面其余都为正面的状况都能实现.于是转化为考虑最终可能出现1的个数的集合有哪些.       因为可能的个数集合是连续的(在最大最小值之内相差2的都可能), 所以每一次翻转之后的上下限都可以根据上一次所得的上下限推出.       最后算排列组合的适合需要用到组合数递推公式和费马小定理推论\( a^{p…

转自:http://blog.csdn.net/yu_xiang/article/details/9227023 在现实Internet网络环境中,大多数计算机主机都位于防火墙或NAT之后,只有少部分主机能够直接接入Internet.很多时候,我们希望网络中的两台主机能够直接进行通信,即所谓的P2P通信,而不需要其他公共服务器的中转.由于主机可能位于防火墙或NAT之后,在进行P2P通信之前,我们需要进行检测以确认它们之间能否进行P2P通信以及如何通信.这种技术通常称为NAT穿透(NAT Trav…
