Anonymous users2024-02-06Frame relay is something that evolved.
Frame relay is a new public data network communication protocol that emerged in 1992 and has been developing rapidly since 1994. Frame relay is an effective data transmission technique that 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, and can be used for both local area network (LAN) and wide area network (WAN) communication. Each Frame Relay user will receive a leased line to connect to the Frame Relay node. For end users, a Frame Relay network handles data transmission to and from other users through a channel that changes frequently and is not visible to the user.
Main features: The user information is transmitted in frames, and the network checks the frame structure and transmission errors in the transmission process, and directly discards the wrong frames.
Frame Relay is a packet-switched communication network that is typically used at the data link layer in the Open System Interconnection Reference Model. Permanent Virtual Circuit PVC is used to form an end-to-end logical link on a physical network switched virtual circuit (SVCS).

Anonymous users2024-02-05Features of Frame Relay:
1.With flexible frame length, it can transmit both short and long frames;
2.By changing the topology of the repeater, the adaptive network topology is realized.
3.It has high fault tolerance and can effectively cope with network topology changes.
4.Frame relay technology can improve the transmission performance and reliability of the network. Expansion: Frame relay technology can better optimize the network structure, effectively reduce network congestion, and improve the transmission efficiency of the network. In addition, it can improve the reliability of the network, effectively increase the availability of the network, and delay the transmission time of packets in the network.

Anonymous users2024-02-04The English name for frame relay is frame relay.
It is a kind of encapsulation protocol BAI for wide area self-network.
Let's first explain what is Frame Relay technology under DU: Zhi is a packet DAO switching technology that provides multiple logical links through a single physical connection.
Frame Relay uses virtual circuits, and each virtual circuit of Frame Relay is identified using DLCI, and the mapping of DLCI to IP addresses is done through IARP (Reverse ARP), and DLCI only makes sense locally.
Can you see it?

2. Frame relay can provide multiple virtual circuits on a physical link 3. Frame relay protocol transmits data information in the form of frames.
4. Frame relay provides a set of reasonable bandwidth management and congestion prevention mechanisms5. Frame relay link layer completes functions such as statistical multiplexing, frame transparent transmission and error detection.

Anonymous users2024-02-01Features: 1. Frame relay technology is mainly used for data transmission services.
2. Bandwidth reuse and dynamic allocation can be realized. The transmission chain used by the frame relay to transmit data information is a logical connection, not a physical connection, and multiple logic connections can be reused on a physical connection, and the multiplexing and dynamic allocation of bandwidth can be realized by using this mechanism.
3. Frame relay greatly simplifies the processing of network nodes and improves the efficiency of network information processing. The two-level structure of the physical layer and the link layer is adopted, and only the core subset part is retained in the link layer.
4. There are no mechanisms such as retransmission and flow control, which saves the overhead of the switch. Statistical multiplexing, transparent frame transmission, and error detection are completed at the link layer, but the retransmission operation after the error is found is not provided, which omits the mechanisms such as frame numbering, flow control, response, and monitoring, which greatly saves the overhead of the switch, improves the network throughput, and reduces the communication delay.
5. Provide a reasonable set of bandwidth management and anti-blocking mechanisms. Users make efficient use of pre-agreed bandwidth, i.e., the promised information rate, and also allow users to occupy unscheduled bandwidth with burst data to improve the utilization of the entire network resources.
