TSO, the full name is TCP segmentation offload, we know that the MTU of Ethernet is usually 1500, except for TCP/IP header, TCP's MSS (Max Segment size) size is 1460, In general, the protocol stack will be more than 1460 of the TCP payload to segmentation, to ensure that the generated IP packet does not exceed the MTU size, but for the support of the TSO/GSO network card, it is not necessary, we can put up

After the network hardware and network protocols are installed, we usually need to test the TCP/IP protocol. How can we perform a comprehensive test? We believe that the comprehensive test should include two aspects: Lan and Internet. Therefore, we should test the LAN and Internet, the following are the steps to test the TCP/IP configuration using the command lin

Let's look at what happens when we enter http://www.mycompany.com:8080/mydir/index.htmlin the browser, behind the scenes.First HTTP is an application layer of protocol, in this layer of protocol, is just a communication specification, that is, because the two sides to communicate, we have to agree to a specification beforehand.1.

Network transmission protocol and http protocol, transmission http protocolOverview: it refers to the constraints and specifications for communication between the server and the client. The data interaction between the client and the server is not disorganized and must follow (based on) certain specifications. Common protocols: A) HTTP and HTTPS Hypertext Transfe

tolerated, so we adopt the UDP transport protocol. But the UDP protocol itself is non-connected and does not provide quality assurance. The high-level protocol rtp/rtcp based on UDP can provide traffic control and congestion control services together. The graph gives a RTP/UDP/IP-based H. 264 frame for video transmission.H. 264 RTP encapsulation strategy for vid

generally 4-4 lower than that of game Virtual Disks ~ 5 Mb/s. This is because the working principle of diskless (System Virtual Disk) varies, and does not affect the use ~ The performance difference of 5 Mbit/s does not lead to a wide gap in the system startup speed. It is likely that there is no difference.3. Whether there is a disk, no disk (System Virtual Disk), a game virtual disk, or a client test can reach a speed of 30 Mb/s, neither the game nor the system will experience a card, however

HTTP network protocol (IV) and http network protocolSecure Web HTTPS HTTP has three obvious disadvantages: Communication uses plain text (not encrypted), and the content may be eavesdropped. If you do not verify the identity of the contact, you may experience disguise. Unable to prove the integrity of the message, so it may have been tampered. Although there

Before learning the LoadRunner agreement, I think we need to understand the basic concept of the agreement. First of all, we know that the communication between computer and computer is inseparable from the communication protocol, and then we say the concept of communication protocol. What is a communication protocol, a communication
