the entire network can be learned. The second-layer switch creates and maintains its own address table. The working principle of a L2 Switch can be inferred from the following three points: 1) because the switch exchanges data on most ports at the same time, it requires a w

rate of the vswitch is, no matter how fast the data transmission rate is, network congestion always exists in the network. This tells us from one side that the absence of Service Quality Control also means that data packets may be lost and the latency may increase. It can be seen that working on switches at a higher level, supporting quality services, relying on software operation and high-level management

Exchange technology is moving in two directions. One Direction is faster and faster, has jumped from the gigabit to the million trillion. Another direction is from the initial 2-tier exchange to the 3-tier exchange, which has now been developed to the seventh layer of the Network application layer Exchange. Figurativ

kinds of information that must be used for network communication: the protocol that the connection uses, the IP address of the local host, the protocol port of the local process, the IP address of the remote host, and the protocol port of the remote process.When the application layer communicates data through the transport layer, TCP encounters a problem that pr

Note: This note is written from the programming perspective, that is, the content is something I think is helpful for programming, rather than from the perspective of a network professional knowledge. The Comparison of Different Computer Architectures: OSI Layer-7 protocol architecture, TCP/IP architecture, and five-layer protocol architecture: It indicates the c

matter how fast the data transmission rate is, network congestion always exists in the network. This tells us from one side that the absence of Service Quality Control also means that data packets may be lost and the latency may increase.

adding network bandwidth, this is an effective and simple method, no matter how high the vswitch's backboard bandwidth is. No matter how large the packet forwarding rate of A vswitch is, no matter how fast the data transmission rate is, network congestion always exists in the network. This tells us from one side that the absence of Service Quality Control also m
