Mesh Topology
The mesh topology incorporates a unique network design in which each computer on the network connects to every other, creating a point-to-point connection between every device on the network. The purpose of the mesh design is to provide a high level of redundancy. If one network cable fails, the data always has an alternative path to get to its destination. Figure 6 shows the mesh topology.

As you can see from Figure 6, the wiring for a mesh network can be very complicated. Further, the cabling costs associated with the mesh topology can be high, and troubleshooting a failed cable can be tricky. Because of this, the mesh topology is rarely used. A variation on a true mesh topology is the hybrid mesh. It creates a redundant point-to-point network connection between only specific network devices. The hybrid mesh is most often seen in WAN implementations. Table 5 summarizes the advantages and disadvantages of the mesh topology.
