<h4 id="rzajtfr-con">Frame relay networks</h4>
|
||
|
|
<p>Frame relay is a protocol that defines how frames are routed through a
|
||
|
|
fast-packet network based on the address field in the frame. Frame relay takes
|
||
|
|
advantage of the reliability of data communications networks to minimize the
|
||
|
|
error checking done by the network nodes. This provides a packet-switching
|
||
|
|
protocol similar to, but much faster than, X.25. The high speed that can be
|
||
|
|
obtained through frame-relay networks makes it well suited for wide area network
|
||
|
|
(WAN) connectivity. Frame relay is commonly used to connect two or more LAN
|
||
|
|
bridges over large distances.</p>
|
||
|
|
<p>The iSeries™ system supports these frame-relay network connections:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Frame relay direct network: Allows data that uses SNA or TCP/IP communications
|
||
|
|
over a frame-relay network to move at speeds of up to 2.048 Mbps. This support
|
||
|
|
allows a network of systems to communicate using the frame-relay network as
|
||
|
|
a backbone, without the need for multiple leased T1 lines.</li>
|
||
|
|
<li>Bridged frame relay network: Allows iSeries to communicate over a frame-relay network
|
||
|
|
through a remote bridge. The bridge is attached to a token-ring, Ethernet,
|
||
|
|
or distributed data interface (DDI) network. Bridged frame relay connections
|
||
|
|
allow iSeries to communicate with stations on the remote local area network
|
||
|
|
(LAN) as if they were attached locally to the LAN medium.</li></ul>
