摘要： A network interconnection device having a router connected by a plurality of links to at least one multiport switch is presented. Each of the plurality of links is connected between one port of the router and one port of the multiport switch such that each link represents a separate path between the router and the multiport switch over which data packets may be transferred. Sets of links are defined as hunt groups, which contain multiple instances of a given resource. Each port has a forwarding engine. When a packet arrives at a router port, the forwarding engine checks if the packet destination port belongs to the same hunt group as the packet sending port. If the destination port and the packet sending port belong to the same group, the packet is sent back through the same port through which it arrived without having to pass through the router backplane, thus transferring the packet efficiently.

摘要： A network device for interconnecting computer networks, the device including a bridge having a plurality of ports through which network communications pass to and from the bridge, the bridge also including a first interface enabling a user to partition the plurality of bridge ports into a plurality of groups, wherein each group represents a different virtual network, wherein the bridge treats all ports within a given group as part of the virtual network corresponding to that group and the bridge isolates said virtual networks from each other, whereby any communications received at a first port of the bridge are directly sent by the bridge to another bridge port only if the other bridge port and the first bridge port are part of the same group.
