Abstract
A gateway routes a packet from a user to a connected network utilizing a per-user routing table. A source address is extracted from the packet; a per-user routing table corresponding to the source address is found, the per-user routing table contains entries corresponding to one or more currently accessible networks for the user and the range of network addresses corresponding to the currently accessible networks; a destination address is extracted from the packet; an entry in the matching per-user routing table with a range of network addresses containing the destination address is sought; the packet is routed to a matching network if the destination address is contained within one of the ranges of network addresses for the currently accessible networks (“ranges”); and the packet is routed to a default network if the destination address is not contained within one of the ranges. Different users may access a different set of networks and select a desired network for access.
