Label: TCP Linux Preface: Groups can occur at the transport layer and network layer. TCP segments in the transport layer and IP segments in the network layer. The IP layer fragment is mostly for UDP Service at the transport layer. Because TCP itself avoids IP fragment, the use of TCP transmission at the IP layer will not cause fragment. When learning the TCP/IP protocol, we know that if the TCP packet segment is long, the segment will occur during sending and the segment will be reorganized duri

Continue to look at concepts. IP protocol The IP protocol is the core of the TCP/IP protocol stack. It provides services such as data transmission, encapsulation of multiple upper-layer protocols, routing and transmission information, and information reporting and exchange technologies. The following describes the services. Data Transmission: The IP protocol provides a connectionless and unreliable data transmission. It cannot guarantee that the other party can receive the data successfully,

Of course, there is no unique answer. The answer to this question varies with systems and requirements, here, I will only analyze the situation of sending chat messages like ICQ. For other cases, you may also get some help: First, we know that TCP/IP is generally considered as a layer-4 protocol system, including the link layer,

communication between client programs and server programs running on the same host through TCP/IP. The general loopback address is 127.0.0.1. Maximum Transmission Unit (MTU): Ethernet MTU is 1500 bytes, IEEE802 MTU is 1492, and SLIP is 296 bytes. If there is a datagram to be transmitted on the IP layer, but the data length is greater than the

is called the MTU, the maximum transmission unit. Most of the different types of networks have an upper limit. If the IP layer has a datagram to be transmitted, and the length of the data is larger than the MTU of the link layer, then the IP layer needs to be fragmented (fragmentation), the datagram is divided into several slices, so that each piece is less than the MTU.Path MTUWhen two hosts on the same n

MTU indicates the maximum transmission unit. MTU values are not necessarily the same for different local networks. for Ethernet, MTU sets the Linux command line to modify the IP address, Gateway, and DNS methods.

In the UDP programming, we are most likely to think of the problem is how many bytes to send a good? Of course, this does not have the only answer, compared to different systems, different requirements, the answer is not the same, I am here only for Like the ICQ type of sending chat messages to analyze the situation, for other situations, you may also be able to get a little help: First of all, we know that TCP/IP is usually considered to be a four-layer protocol system, including link layer, ne

If the server does not respond within the specified time, the connection fails.4.
