Re: Frame Relay?

hi,

Please read information available at:
http://www.alliancedatacom.com/manufacturers/cisco-systems/framerelay_design/framerelay.asp

contains all pertinent information. Below a short quote.


Frame Relay is a high-performance WAN protocol that operates at the physical and data link layers of the OSI reference model. Frame Relay originally was designed for use across Integrated Services Digital Network (ISDN) interfaces. Today, it is used over a variety of other network interfaces as well.

Frame Relay is an example of a packet-switched technology. Packet-switched networks enable end stations to dynamically share the network medium and the available bandwidth. The following two techniques are used in packet-switching technology:

* Variable-length packets
* Statistical multiplexing

Variable-length packets are used for more efficient and flexible data transfers. These packets are switched between the various segments in the network until the destination is reached.


hope this helps!

Re: Frame Relay?

Hi

Frame relay is a telecommunication service designed for cost-efficient data transmission for intermittent traffic between local area networks (LANs) and between end-points in a wide area network (WAN). Frame relay is based on the older X.25 packet-switching technology which was designed for transmitting analog data such as voice conversations. Unlike X.25 which was designed for analog signals, frame relay is a fast-packet technology, which means that the protocol does not attempt to correct errors. When an error is detected in a frame, it is simply "dropped." (thrown away). The end points are responsible for detecting and retransmitting dropped frames.

Re: Frame Relay?

also, Frame relay can be viewed as 'bandwidth on demand' since telephone companies can charge on a 'per usage' or 'per packet' basis.


It can thus be one of the less expensive options for WAN links if your intended usage is going to be low.
