What is Frame Relay?

Frame relay (frame relay) is a new public data network communication protocol that emerged in 1992, and has rapidly developed since 1994. Frame relay is an effective data transmission technology. It can quickly and inexpensively transmit digital information in one-to-one or one-to-many applications. It can be used for voice and data communication. It can be used for both local area network (LAN) and wide area network (WAN) communication. Each Frame Relay user will get a dedicated line to the Frame Relay node. For the end user, the frame relay network handles data transmission with other users through a channel that is often changed and not visible to the user.

A public data network is a communications network established and operated by a telecommunications authority or a widely recognized private institution. The communication network provides data transmission services to the public in some way.

For example, in China,

Internet Protocol (English: Internet Protocol, abbreviated as IP), also translated Internet Protocol, is used for

Asynchronous Transfer Mode (ATM), also known as cell relay. ATM adopts the circuit switching method, which uses the cell as a unit. Each cell is 53 bytes long. The header occupies 5 bytes.

ATM can ideally implement various QoS, which can support both connected services and connectionless services. Is a model of broadband ISDN (B-ISDN) technology. ATM is a switching technology. When sending data, the digital data is first cut into multiple fixed-length data packets, and then sent using optical fiber or DS1 / DS3. When you reach your destination, regroup. ATM network can integrate sound, video and data at the same time. Provide the best transmission environment for various types of information. ^[1]
