- 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...

- A Reliable Subcasting Protocol for Wireless Environments
- This paper presents an end-to-end reliable multicast protocol for use in environments with wireless access. It divides a multicast tree into sub-trees where subcasting within these smaller regions is applied using a tree of Retransmission Servers RSs. RM2 is receiver oriented in that the transmitter does not need to know...
