How Frame Relay Works

Frame Relay Error Handling Frame Relay uses the Cyclic Redundancy Check (CRC) method for error detection. Frame Relay services perform error detection rather than error checking; error detection is based on the premise that the underlying network media is reliable. Frame Relay error detection uses the CRC checksum to determine if the frame is received by the Frame Relay networking device (router or frame relay dlci switch) with, or without, error. Error correction is left to the upper-layer protocols, such as the TCP (of the TCP/IP protocol suite). NOTE: Error detection detects errors, but does not make attempts to correct the condition. Error correction detects errors and attempts to correct the condition, usually under control or direction of a higher-layer protocol. The termination node performs error detection. Frame Relay Frame Format Figure 15-13 illustrates the standard Frame Relay frame format. Figure 15-13: Frame Relay Standard Frame Format (Click image for larger view in a new window) Table 15-7 presents a description of each of the Frame Relay standard frame fields. Field Description Flags Delimits the beginning and end of the frame. The value of this field is always the same and is represented as hexadecimal 7E or as binary 0111110. Address Contains the following information: DLCI -- The 10-bit DLCI is the most significant part of the Frame Relay header. This value identifies and represents the VC* between the FRAD and the Frame Relay [network service provider] switch. Each VC that is multiplexed onto a physical channel will be re

of equipment from different vendors. Frame Relay, which is a relatively new wide area networking method, is frame relay switch gaining popularity. Like X.25, it uses a packet-switching technology, but it's more efficient than X.25. As a result, it can make your networking quicker, simpler, and less costly. Frame http://www.enterprisenetworkingplanet.com/netsp/article.php/10953_962071_2/Frame-Relay-Polling-Error-Handling-and-Specification-Enhancements.htm Relay was developed to solve communication problems that other protocols could not: the increased need for higher speeds, an increased need for large bandwidth efficiency, particularly for clumping ("bursty" traffic), an increase in intelligent network devices that lower protocol processing, and the need to connect LANs and WANs. Like X.25, Frame Relay is a packet-switched protocol. But http://www.cpcstech.com/frame-relay-information.htm the Frame Relay process is streamlined. There are significant differences that make Frame Relay a faster, more efficient form of networking. A Frame Relay network doesn't perform error detection, which results in a considerably smaller amount of overhead and faster processing than X.25. Frame Relay is also protocol independent—it accepts data from many different protocols. This data is encapsulated by the Frame Relay equipment, not the network. The intelligent network devices connected to a Frame Relay network are responsible for the error correction and frame formatting. Processing time is minimized, so the transmission of data is much faster and more efficient. In addition, Frame Relay is entirely digital, which reduces the chance of error and offers excellent transmission rates. Frame Relay typically operates at 56 kbps to 1.544 Mbps. What does Frame Relay do? Frame Relay sends information in packets called frames through a shared Frame Relay network. Each frame contains all the information necessary to route it to the correct destination. So in effect, each endpoint can co
