1. 介绍 ICE (Interactive Connectivity Establishment)协议基于SDP offer/answer 模式,为多媒体传输协议定义了一套NAT穿越机制。ICE 对每一种流媒体都提供了一系列候选传输地址,流媒体双方可以利用STUN (Session Traversal Utilities for NAT)来进行数据连接。通常情况下,ICE 的候选地址大都是基于UDP协议的,但是TCP协议...

These are used to terminate a TCP session- more specific (RST) is used when a half open or SYN, ACK-SYN but no ACK from the client is received, tying up a TCP session in the TCP/IP stack on the server which the RST resets and kills the connection. FIN is used when you close yo...
About the TCP Connection establishment, you can check this good explanation of NetAcad: TCP Three-Way Handshake Using the Wireshark outputs, you can examine the operation of the TCP 3-way handshake: Step 1 A TCP client begins the three-way handshake by sending a segment with the SYN (Synch...
A method for acceleration of TCP connection establishment between a client and a server in a network includes deploying at least one stateful switch with packet generation capabilities in the network, and configuring the at least one stateful switch to receive a TCP SYN segment from the client, ...
offer peer的实现与answer相似。 offer peer启动后会建立RTCPeerConnection类型实例,并设置RTCPeerConnection实例的事件处理函数: OnICECandidate OnConnectionStateChange DataChannel的OnOpen DataChannel的OnMessage offer peer会主动创建DataChannel,然后与信令服务器建立连接,并发送请求到信令服务的/offer端点并主动向信令服务器...
/* Send a crossed SYN-ACK during socket establishment. * WARNING: This routine must only be called when we have already sent * a SYN packet that crossed the incoming SYN that caused this routine * to get called. If this assumption fails then the initial rcv_wnd ...
Tracing data packets after the connection establishment As shown inFigure 1, the TCP client and the TCP server transmit data packets after they establish a TCP connection. The TCP connection trace feature traces data packets and records the connection information. If you enable this feature on both...
