[Background Knowledge] MTU: The maximum transmission unit of maxitum transmission unit (meaning different link layer bearer networks are used for Internet interconnection, such as Ethernet, PPP, and old slip,It is generally the maximum number of bytes of d

The Windows operating system uses the maximum transmission Unit (MTU) to determine the maximum size of protocol packets (Protocol data packet) that can be transmitted over the network layer below. The MTU parameter usually occurs in communication with an interface (NIC, serial port, etc.), and each interface is set separately. To achieve optimal network performance, and to prevent fragmentation (fragmentat

MTU Maximum Transmission UnitThrough the definition of the above MAC package, we now know that the standard Ethernet frame can transmit the maximum amount of data to reach the bytes, which is called the MTU (Maximum transmission unit, the maximum transmission unit). You have to be aware that the MTU of each network interface is different, so sometimes you will se

Description of the necessity and importance of setting MTU in linux: FTP is a popular program recently used to upload files. But this very dish program made my head hurt for half a month. I deployed my program on linux and uploaded files below 1 kb, but files above 1 kb cannot be uploaded. There is no problem in deploying programs on WINDOWS, and there is no problem in uploading my programs to my own FTP server. Therefore, it is determined that it is

The so-called MTU, that is, the maximum transmission unit, which is the maximum information packet value of network transmission, the MTU value of the general TP-LINK router is the default value, change the MTU value can improve the efficiency of the router, however, if the MTU value exceeds the ISP's requirement, the

1. TCP path MTU Detection (1) determine the maximum capacity of the Data Part Of The sent packet based on the MTU and the MSS carried by the peer Syn (if the peer does not specify the MSS, the default value is 536 );(2) Open the DF flag in the IP header;(3) If the ICMP error message is received, it indicates that the Shard is required. If the ICMP message contains the next-hop

The so-called MTU, that is, the largest transmission unit, which is the network transmission of the largest packet value, the General Tp-link router's MTU value is the default, changing the MTU value can increase the efficiency of the router, but the MTU value exceeds the ISP requirements will not be able to transfer,

When we learn the TCP/IP protocol, we know that if the TCP message segment is very long, it will be fragmented at the time of sending, and when it is accepted, the same IP datagram will occur when the length exceeds a certain value, and the Shard will be re-reorganized at the receiving end.Let's look at two concepts that are closely related to TCP segment segmentation and IP datagram fragmentation.MTU (maximum transmission unit)The MTU is already ment

Label: MTU, causing transmission failure Symptom: failed machine wget cannot be downloaded, and the test machine cannot issue the SCP file to the faulty machine, but the faulty machine can issue the SCP file to the test machine. Tcpdump packet capture on the faulty machine finds that the data packet transmission between the faulty machine and the test machine is very slow, and the MTU problem of the fau

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, becau

ObjectiveModifying the MTU value (that is, the maximum number of transmit bytes for a packet) may not be significant to the personal Internet user, after all, we do not have so much traffic. However, for the server is very unusual, the other side of this is to show your network expertise, on the other hand, improve network performance, so it is a small skill worth mastering. The following respectively describes the Windows and Linux

The concept of fragmentation is a bit unclear in the early stages, see a good article, MarkThis article transferred from: http://blog.csdn.net/keyouan2008/archive/2010/08/27/5843388.aspx1,MTU (Maximum transmission UNIT,MTU), Max transmission Unit(1) Ethernet and 802.3 have a limit on the length of the data frame, the maximum value is 1500 and 1492 bytes respectively. This feature of the link layer is called

Busybox is not included in the default Android system, so you cannot use busybox ifconfig to view and modify MTU values. In fact, the MTU value of the NIC is saved in the/sys/class/NET/eth0/MTU file. Therefore, you can modify the MTU by viewing and modifying the file: The following uses viewing and modifying eth0 as

MSS is the abbreviation of the Maximum Segment Size of maxitum segment size, meaning the maximum data segment that TCP data packets can transmit each time. It is a concept in the TCP protocol. The MSS value indicates the size of the TCP packet's net load data. The setting of the packet size can achieve the same effect as setting the MTU value. It is to prevent the packet size sent by the host from exceeding the MT
