balancing if you want to really understand the content of the seven-tier application layer, you can only proxy the final server and the client to establish three handshake connections, it is possible to accept the client sends the real application layer content of the message, so the seven-tier load balancer is more like a proxy server . As TCP becomes more and more complex, many applications, such as the DTLS Protocol (the UDP version of SSL) a

Does HTTP have to be performed on TCP?Does SSL have to be performed on TCP?...In fact, HTTP does not stipulate that it must be executed on TCP, or even FTP is not necessarily executed on TCP! HTTP or FTP is simply that the underlying channel to ensure that the data in the sequential transmission and reliable arrival, because the transport layer in addition to TCP no other well-known protocol to meet this demand, so most of the applications have chosen TCP, but you know, this is not mandatory.SSL

Linux Network Programming 5-use UDP protocol for group chat and network programming udpIntroduction The functions implemented in this article are similar to what I wrote earlier (select System Call _ 2 in Linux). The difference is that the communication methods between processes are different. In the previous article, I used pipelines. In this article, I will use the socket interface.Requirement The client sends a message to the server. After receivin

ARP part IP ICMP UDP part TCP Section 1. UDP IntroductionUDP is a simple datagram-oriented transport layer protocol. Each output operation of a process generates a UDP datagram and assembles it into an IP datagram to be sent. This is different from the stream-oriented character protocol, such as TCP. The full data generated by the application may be unrelated to

UDP packet LengthThe theoretical length of UDP packetsWhat is the theoretical length of UDP packets and what should be the appropriate UDP packets? As can be seen from the packet header of the UDP packet in the 11th chapter of TCP-IP, the maximum packet length of

The User Datagram protocol, or UDP, is a simple transport layer protocol for datagrams: Each output of a process produces only one UDP datagram, which sendsAn IP datagram.The process accesses UDP by creating an sock_dgram type of socket within an Internet domain. This type of socket is referred to as a non-connected by default. Each process sendsData, you must sp
