ABSTRACT:
A method manages transfer of multiple destination packets received at edge devices on a connection oriented network, providing LAN emulation, where the connection oriented network provides emulation of one or more variant network protocols for systems coupled to the edge devices. The method includes maintaining status information for each port on edge devices on the connection oriented network, which provides an indication of network protocols not in use by systems accessible through the respective ports. Multiple destination packets received at an incoming port on an edge device are sent via the connection oriented network to a server on the connection oriented network. At the server, the network protocol for which the multiple destination packet is intended is determined. The server transmits via the connection oriented network the multiple destination packet to ports of edge devices, other than the incoming port, and other than ports for which the status information indicates that the determined network protocol is not in use by systems accessible through the port. The status information is learned at the edge devices based on activity on the respective ports, and reported by the edge device to the server.
