Frame Relay Topologies

One of the first items that you should consider when designing a Frame Relay network, or any type of regional WAN, is how the connectivity is to be laid out. When considering Frame Relay for a WAN media, you can choose from the following three basic design approaches:

• Star topology— A topology where end points on a network are connected to a common central switch by point-to-point links.

• Fully meshed topology— A topology where devices are organized in a mesh topology, with each network node having either a physical circuit or a virtual circuit that connects it to every other network node.

• Partially meshed topology— A topology where devices are organized in a mesh topology, with some network nodes organized in a full mesh ...
