1.UDP Brief Introduction UDP is a transport layer protocol, and TCP protocol is in a hierarchy, but unlike the TCP protocol, UDP protocol does not provide timeout retransmission, error retransmission and other functions, that is,

This paper uses two graphs to comb the knowledge of TCP-IP protocol. The TCP communication process consists of three steps: establishing a TCP connection channel, transmitting data, and disconnecting the TCP connection channel. As

These days because of the laboratory off the net, so has been unable to send essays, but good habits still have to insist.Today, let's talk about an important layer-the transport layer. The Protocol of Transport layer is mainly divided into TCP protocol and UDP protocol. The former is referred to as Transmission Contro

Because the ASP is usually run in conjunction with the Web server, the Web server usually needs to install the TCP/IP protocol. However, the TCP/IP protocol cannot be run separately, so you must match With the use of the network c

converts data to a continuous byte stream, but cannot distinguish the basic message and message boundary of word throttling. After the byte stream is received, the upper-layer application interprets the byte stream as a message. It can be said that the sender encapsulates data into TCP data packets by protocol, and the receiver also reads data from TCP data pac

1. Brief Introduction to UDP UDP is a transport layer protocol, which is in a layer with TCP protocol. However, unlike TCP, UDP does not provide timeout retransmission, error retransmission, and other functions, that is, it is an unreliable protocol.2. UDP header 2.1.udp por

the PCI Express interface will be available early next year, the 10G Ethernet chip for optical fiber and copper wires supporting TCP/IP uninstallation will also be available within a year and a half. Analysts said it would take several years for chip manufacturers to determine all the details about how they can accelerate TCP/

TCP-IP learning notes of UDP (User Datagram Protocol) I. Introduction UDP is a simple datagram-oriented transport layer protocol: Each output operation of the process generates a UDP datagram, and assembled into an IP datagram to be sent. This is different from the stream-or

ICMP transmits errors and management messages between IP systems and is an integral part of any IP implementation and requirements. ICMP can be divided into two categories: Error and query. Inquiry messageis defined by a pair of requests and answers. Error messages typically contain the IP header (and options) of the first shard of the

Sends an ARP request and receives an ARP reply for the ARP module. Send Rarp request and receive RARP response for Rarp

TCP/IP stackProcesses incoming and outgoing IP data packets, and routes the data packets to the application that processes the data. Due to its own defects, the openness of the network, and hacker attacks are the main reasons for the security of the interconnected network. TCP/IP
