- IP-Multicasting Technology Part 2: Switches vs. Routers
- One of the primary difficulties encountered in multicasting over Layer-2 switches or bridges is that the normal response to multicast traffic is the immediate flooding of the packets to every interface on the switch other than the interface from which the packet arrived. This response is typical of a switch...
