Editor's Notes
- This is what a multi-layer switched backbone will look like. This could be frame based backbone or a cell based backbone, the principle is the same: Traffic within a subnet will be switched at layer 2. Traffic between subnets will be routed at layer 3 (but at the spped of switching). Other protocols (including non-routable protocols such as netbios) will be bridged. The multi-layer switch must also be capable of talking and interoperating with existing routers.
