The future and performance of TCP connections when TCP was just 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 correspond to the current changes. They are path MTU discovery. Window expansion options and time

an application to set the length of the receive and send caches, and most systems provide a UDP datagram that reads and writes more than 8192 bytes by default.Kernel implementations : There may be some implementation features (or errors) that make the IP datagram length less than 65535Although IP can send such a long datagram, the application is not guaranteed to be able to read data of that length. Therefore, the UDP programming interface allows the application to set the maximum length that c

loopback interface.(4) the loopback interface can be viewed as another link layer below the network layer. The network layer transmits a datagram to the loopback interface as if it were passed to the other link layer, except that the loopback interface returns it to the IP input queue. as you can see from figure 2-4, IP datagrams sent to the host's own IP address generally do not appear on the appropriate network . 7, Maximum transmission Unit MTUEthernet and 802.3 have a limit on the length o

Before we used the Docker container, we learned that Docker was isolated from the container network implemented by the Linux network namespace. When using Docker, there will be a Docker0 Linux Bridge,brctl show on the physical host or virtual machine to see Docker0 "plugged in" a lot of veth network devices: # ip link show... ...3: docker0: mtu 150

Different networks due to the different physical characteristics of

What is RGB full range? In short, the TV set generally only supports 240 levels, from 16 ~ 255. The computer monitor supports 255 levels, from 0 ~ 255. RGB full range is enabled in the display option of the PS3, that is, 0 ~ is output to the TV ~ 255 of the full-color signal. Do you want to open it? The answer is: If you want to enable the video, enabling the RGB full range will make the video more colorful. However, if you don't support the TV, the

addresses. As for ARP and RARP, ARP is called the Address Resolution Protocol. It is a protocol that uses IP addresses for MAC addresses, while RARP is called the Reverse Address Resolution Protocol, I will introduce them later in the TCP/IP protocol (using ARP in the LAN can easily paralyze the network) There are still a lot of data link layer protocols, including the most commonly used Ethernet (that is, the network card we usually use) protocols, the uncommon licensing ring, and FDDI. Of cou

An IP datagram that passes a loopback interface cannot appear on any networkFigure 4 Process of IP datagram processing by loopback interface1) Any data passed to the loopback address (typically 127.0.0.1) as an IP input2) A copy of the datagram to the broadcast address or multicast address is transmitted to the loopback interface and then sent to the Ethernet because the definition of broadcast and mu

When it comes to UDP programming, the easiest thing to think about is how many bytes are sent at a time? Of course, this does not have the only answer, compared to different systems, different requirements, the answer is not the same, here just like the ICQ type of sending chat messages to analyze, for other cases, may also get a little help: First of all, we know that tcp/ IP is generally considered to be a four-layer protocol system, including link layer, network layer, Transport layer, appl

receive the header before receiving the subsequent part ), this overhead is not large at all. If the length of your UDP data exceeds the upper limit, consider re-designing the packet structure. The last article is a good one.: During UDP programming, the most common question is 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 ot

I. MTU Both Ethernet and IEEE 802.3 have limits on the length of data frames. The maximum values are 1500 and 1492 bytes respectively. These limits are called the maximum transmission unit (MTU, maximum transmission unit)If there is a datagram to be transmitted on the IP layer and the data length is greater than the MTU on the link layer, fragmentation is require

Configure jumbo frame for RAC optimization and jumboframe for rac Optimization Configure jumbo frame for RAC Optimization) First, let's talk about the concept of MTU: in network communication, there is a concept of MTU (Max Transmission Unit), that is, the maximum frame size in network Transmission, the default value is 1500 bytes (the Ethernet Variable frame size is 46-1500Byte ).

how does one detect the MTU of the Gateway? open the DOS window on the local machine and run: Ping-F-l 1472 192.168.0.1, where 192.168.0.1 is the gateway IP address and 1472 is the length of the packet. Note that the preceding parameter is "-l" (lower-case l), rather than "-1 ". If the packet can be pinged, it means that the packet does not need to be split and can be sent out through the gateway. If packet needs to be fragmented but DF set appear

During UDP programming, the most common question is how many bytes are sent at a time? Of course, there is no unique answer. The answer to this question varies with the requirements of different systems.For example, if you want to analyze the situation of sending chat messages like ICQ, you may also get some help in other situations:First, we know that TCP/IP is generally considered as a layer-4 protocol system, including the link layer, network layer, transport layer, and application layer.UDP
