Abstract: Techniques for aggregating hardware routing resources in a system of devices are provided. In one embodiment, a device in the system of devices can divide routing entries in a software routing table of the system into a plurality of route subsets. The device can further assign each route subset in the plurality of route subsets to one or more devices in the system. The device can then install, for each route subset that is assigned to the device, routing entries in the route subset into a hardware routing table of the device.

Abstract: Techniques for virtualizing hardware hash tables in a networking system are provided. In one embodiment, the networking system can maintain a plurality of virtual hash tables corresponding to a plurality of hardware hash tables in the networking system. For each hardware hash table and its corresponding virtual hash table, the networking system can intercept operations directed to the hardware hash table and apply the intercepted operations to the virtual hash table. The networking system can then selectively install and/or uninstall virtual hash table entries to/from the hardware hash table in view of the operations.

Abstract: Techniques for reducing broadcast and multicast traffic in a stacking system are provided. In one embodiment, a master device in the stacking system can automatically determine a minimal set of VLAN associations for stacking links in the stacking system. The minimal set of VLAN associations can avoid unnecessary transmission of broadcast or multicast packets through the system's topology.

Abstract: Wireless roaming in a computer network may be handled through a solution provided on one or more switches in the network. A roam request sent by a switch corresponding to the user's new location may be received by the other switches in the network. If the user is known to any of these switches, then they may execute steps to accommodate the roaming. The tasks performed may vary based on whether the roaming is on layer 2 or layer 3, whether the switch is a home agent for the client, and/or whether the switch already corresponds to the user's new location.
