In TCP/IP tiering, the data link layer uses the MTU (Maximum transmission Unit, Maximum transmission unit) to limit the packet size that can be transmitted, and the MTU refers to the maximum length of data transmitted at one time, excluding the frame header of the data Link layer data frame. If the MTU of the Ethernet is 1500 bytes, the maximum length of the data

segmentation occurs at the network layer. However, for segments, this often happens on the UDP Transport Layer Protocol, which rarely happens on the transport layer using TCP channels. 1, MTU (maximum transmission unit, MTU), maximum transmission unit (1) Ethernet and 802.3 have a limit on the length of data frames. The maximum values are 1500 and 1492 bytes, respectively. This feature of the link layer is

TCP/IP Study Notes (14)-future and performance of TCP connections When TCP was born, its main operating environment was low-speed networks such as Ethernet and slip. With the emergence of high-speed networks, the requirement for higher TCP protocol throughput and higher efficiency is becoming more and more urgent. To this end, TCP has added three important mechanisms to adapt to current changes. They are Path MTU found. Window expansion options an

components "congenital" incompatibility caused; obviously, Frequent interruption of the phenomenon will lead to ADSL internet speed greatly reduced. To effectively improve ADSL transmission speed, you have to find ways to stop ADSL frequent cut-off phenomenon; To do this, in fact, is very simple, you can go to Ftp://61.155.52.131/adslpatch. EXE to obtain a system patch, and then install the patch on the computer system where the ADSL, so that the Windows 98 system of ADSL-related network compon

. (4) MTU The Maximum Transmission Unit (MTU) represents the maximum number of bytes that are supported by the information field of the protocol running on the interface. Because the maximum length of the information field for an Ethernet frame is 1500 bytes, its MTU is displayed as 1500 bytes. For almost all Ethernet applications, the default 1500-byte

When talking about IPv6 technology, we always compare it with IPv4. So what is the praise of IPv6 technology? Now let's summarize the advantages of IPv6 technology. First, let's introduce our topic today from the issue of ultra-long data transmission. How does IPv6 technology solve the problem of ultra-long data transmission? IPv6 requires that each link on the Internet has a maximum transmission unit (MTU) of 1280 or more eight-bit groups ). Links th

Conclusion: not only can the TCP protocol divide data segments, but the IP protocol also has this function. The reason for this is that both are restricted by the underlying MTU (although TCP splits data packets according to MSS restrictions, because MTU = TCP packet header + IP packet header + MSS, it is actually restricted by MTU .). But try not to let the IP p

The maximum size of a UDP package can be larger. 1. When programming with UDP, we are most likely to think of the problem of how many bytes are sent at a time? Of course, there is no unique answer. The answer is different from the requirements of different systems. Here I only analyze the situation of sending chat messages like ICQ, in other cases, you may also get some help: First, we know that TCP/IP is generally considered a layer-4 protocol system, including the link layer, network layer, tr

(MTU) is related to the MTU of the network. let's take a look at MTU: MTU (Maximum Transmission Unit) is the largest packet transmitted over the network. the unit of MTU is byte. for example, Ethernet can only send 1500 bytes in a frame, while a typical

Any other possibilities There are multiple causes of the stick package problem: 1. SQ_SNDBUF socket itself has a buffer size limit (sending buffer and receiving buffer) 2. limits on the size of the MSS client transmitted over TCP 3. The link layer also has the MTU si

We have explained in detail the PPPoE server configuration for Windows XP. Here we will introduce other aspects. First, let's take a look at setting the PPPoE service name. PPPoE service name The Windows XP operating system provides great convenience for users. When trying to connect, the system automatically searches for the service name. Therefore, you do not need to manually set the PPPoE service name. This function is valid for most users. If you need to specify a specific service name, you
