WCF message frame format

Http://www.cnblogs.com/shanyou/archive/2009/06/12/1502385.html

In the TCP/IP protocol stack, when data flows down through the protocol stack, each layer must add control information to the data to ensure correct transmission. The control information is placed at the beginning of the transmitted data, which is called the header. The process of adding information to each layer of the protocol stack is calledEncapsulation. That is to say, each layer of the stack must be formatted to adapt the transmitted data to a specific protocol, that is, each layer must add a header corresponding to the Protocol on the basis of the upper layer; when data flows in the opposite direction (from the bottom layer) of the protocol stack, the protocol software processes the data in the opposite way, that is, each layer is stripped of the header added to the corresponding layer of the stack, then pass the data to the previous layer, which isUnseal.

Data is the entity and service object transmitted by the network and TCP/IP protocol stack. When a user sends data to the Internet, the user group is first packaged (that is, the application data packet ), then, it is routed down to the transport layer. TCP is a stream-oriented protocol. The high-level protocol is not stream-oriented. You need to design the Message Size, start point, and end point. This is the message frame format.

In WCF, the message frame format is used to support TCP transmission and soap messages. If WCF does not provide default support for UDP, You Need To Implement UDP transmission by yourself.

In his blog, Nicholas Allen wrote a series of articles to illustrate the message frame format of WCF:
