internet protocol tcp ip properties

layer protocol IP uses a specific protocol number (TCP 6,udp 17) to represent and differentiate the Transport layer protocol. The services provided by any TCP/IP implementation are the

long or short. In addition, when the vro cache is saturated or overflows, the group data may be lost and cannot be sent to the peer end. The features of circuit switching and group switching have been demonstrated. The TCP/IP protocol implements communication between hosts. TCP/

About portsCommunication between any two hosts on the internet is from one end to the other, also known as end-to-end communication.What is a port?Modern operating systems are equipped with many applications, information to my computer how do I know this message is passed to my QQ application? My QQ program is responding but my MSN did not respond to it?The reason: My system has a number of port numbers, each application process is bound to a unique l

Protocol: rules, standards, or conventions established for data exchange (communication) in the network. (= Semantics + syntax + rules) TCP/IP has become an industrial standard for Internet communication. TCP/IP model:

parameter problem (theIP header field is wrong), and the routing (change of path) is changed. 1.3.2. QueryThis is primarily used for loopback requests and responses (judging whether they are reachable), timestamp requests, and questions and answers (time synchronization) in both cases.1.4. ICMP Example1.4.1. PingDetermine if the destination host is reachable.1.4.2. TracertDisplays the routing path to which the destination host will pass.2.TCP(

http://view.inews.qq.com/a/20161025A0766200QQ in narrowband eraQQ is a narrow band of the most representative of the product, in that network transmission efficiency is lower than the era, we still remember Google's homepage? Why is the simple page of Google so concise?Google was born in 1998, is also in the narrow-band era, you will find its home byte size is less than 1024, why less than 1024 bytes, because the Ethernet MTU (that is, the largest transmission unit) is 1024,google in order to le

HTTP, FTP, SMTP, Telnet, etc. protocol, Oh! That HTTP protocol is the protocol that's used to access the Web. Actually ... You know, we should understand him from the reality, understand the function and function of the network protocol, and then from the fundamental point of view he is concrete how to achieve. We can

Finally saw the TCP protocol, which is the most important and the most exciting part of the TCP/IP details, to spend great effort to read. In front of TFTP and BOOTP are some simple agreement, do not write notes, write up nothing. TCP and UDP are in the same layer---transpor

Finally see the TCP protocol, this is the TCP/IP detailed inside the most important is the most exciting part, it will take great effort to read. The previous TFTP and BOOTP are simple protocols, no notes, no writing. TCP and UDP are at the same level---transport layer, but

One; prefaceThe people who have learned the TCP/IP protocol have a feeling, this thing is too abstract, there is no data instance, after reading soon forget. This article will introduce an intuitive learning method, using the Protocol analysis tool to learn TCP/

Internet technology in wireless networks. At the same time, the huge interconnectivity of the global Internet is a great incentive. Because small devices such as sensors are often required to be small and cheap, the implementation of network protocols must handle limited computing resources and memory. This article describes the design and implementation of a small TCP
