Origin Frame Relay

-














x.25 provides quality of service , error-free delivery, whereas, frame relay designed relay data possible on low error networks. frame relay eliminates number of higher-level procedures , fields used in x.25. frame relay designed use on links error-rates far lower available when x.25 designed.


x.25 prepares , sends packets, while frame relay prepares , sends frames. x.25 packets contain several fields used error checking , flow control, of not used frame relay. frames in frame relay contain expanded link layer address field enables frame relay nodes direct frames destinations minimal processing. elimination of functions , fields on x.25 allows frame relay move data more quickly, leaves more room errors , larger delays should data need retransmitted.


x.25 packet switched networks typically allocated fixed bandwidth through network each x.25 access, regardless of current load. resource allocation approach, while apt applications require guaranteed quality of service, inefficient applications highly dynamic in load characteristics or benefit more dynamic resource allocation. frame relay networks can dynamically allocate bandwidth @ both physical , logical channel level.
