What method does ATM use?

Edit:GQ International Trade Co.,LtdUpDate:Apr 17, 2018

ATM is a kind of packet switching and multiplexing technology based on cell. It is a universal connection-oriented transmission mode designed for multiple services. It is suitable for LAN and WAN, it has high-speed data transmission rate and support. Many types of communication such as voice, data, fax, real-time video, CD-quality audio and images.

ATM adopts a connection-oriented transmission method, which divides data into fixed-length cells, exchanges them through virtual links, and integrates ATM switching, multiplexing, and transmission. In the multiplexing, asynchronous time-division multiplexing is used to pass information. The header or header to distinguish between different channels.

ATM transmission protocol adopts asynchronous transmission mode, which means that it is sent out regardless, and the receiving party's acceptance rate is guaranteed by a third party or no one guarantees at all. The correct rate of such an agreement cannot be guaranteed, but when the network conditions are good, For example, the dedicated line, transmission efficiency is high, it does not require complicated verification and verification, many private networks use similar protocols.
