What is Frame Relay Frame Relay (Frame Relay) is a network and data terminal equipment (DTE) interface standard. Because the fiber network has a much lower bit error rate than the early telephone network, it can reduce some of the error control processes of X.25, which can reduce the processing time of nodes and improve the throughput of the network. Frame relay is generated in this environment. Frame relay provides the protocol specifications of the data link layer and the physical layer. Any high-level protocol is independent of the frame relay protocol. Therefore, the implementation of frame relay is greatly simplified. At present, one of the main applications of frame relay is LAN interconnection. Especially when the LAN is interconnected through a wide area network, the use of frame relay can better reflect its advantages of low network delay, low equipment cost and high bandwidth utilization. The main features of frame relay are: using optical fiber as the transmission medium, so the bit error rate is extremely low, can achieve approximately error-free transmission, reduce the overhead of error checking, and improve the throughput of the network; frame relay is a Broadband packet switching, when using multiplexing technology, its transmission rate can be as high as 44.6Mbps. However, Frame Relay is not suitable for transmitting real-time information such as voice, TV, etc., it is limited to transmitting data. Physical topology: switches, access links, trunks, CSU / DSU Frame relay technology is a fast packet switching technology that uses simplified methods to transmit and exchange data units at the data link layer. Frame relay technology was born and developed under the conditions that packet switching technology is fully developed, digital and optical fiber transmission lines are gradually replacing existing analog lines, and user terminals are becoming more intelligent.

Frame relay only completes the functions of the physical layer of the OSI and the core layer of the link layer, leaving flow control and error correction to the intelligent terminal, which greatly simplifies the protocol between the node machines; at the same time, frame relay uses virtual circuit technology, Can make full use of network resources, so frame relay has the characteristics of high throughput, low delay, suitable for sudden business and so on. Frame relay is an important option for ATM networks. Frame relay is introduced into ISDN as a bearer service added to the packet mode. Its frame structure is consistent with the LAPD structure of ISDN and can be logically multiplexed.
