It provides multiple substreams Through multiplexing on a single link. It also provides multi-channel self-addressing support, in which the link terminal can be expressed by multiple IP addresses (representing multiple physical interfaces), so that even if one of the connection fails, it will not be interrupted

1 IntroductionIn recent years, with the exponential growth of the Internet, it has put forward higher requirements for WAN bandwidth. Internet service providers (ISPs) are actively exploring various technologies to better connect to their backbone routers. The common approach is the adoption of asynchronous transfer mode ATM) technology, using 155 M (STM-1) up to 622 M (STM-4) of high-speed links. As a result, many IP over ATM technologies are generat

At the network layer, each LAN is connected to each other based on the IP protocol and eventually forms a global Internet.

Currently, three most popular IP transmission technologies are available: IP over ATM, IP over SDH, and IP over WDM. All three IP transfer technologies will play their own roles in different periods of telecommunication network development and different parts of the network.
