Per user and network routing tables
First Claim
1. A method for routing a packet sent from a user in a system in which the user may be connected to multiple networks simultaneously, including:
- extracting a source address from the packet;
finding a per-user routing table corresponding to said source address, said per-user routing table unique to the user and containing entries corresponding to one or more currently accessible networks for the user and the range of network addresses corresponding to said currently accessible networks;
extracting a destination address from the packet; and
routing the packet to a matching network if said destination address is contained within one of said ranges of network addresses for said currently accessible networks.

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.

4. A gateway for routing a packet sent from a user in a system in which the user may be connected to multiple networks simultaneously, including:
-
a packet source address extractor; a memory containing one or more per-user routing tables, each of said routing tables unique to a user and containing entries corresponding to one or more currently accessible networks for the corresponding user and the range of network addresses corresponding to said currently accessible networks; a per-user routing table searcher coupled to said packet source address extractor and coupled to said memory; and a matching network router coupled to said per-user routing table searcher. - View Dependent Claims (5, 6)

7. An apparatus for routing a packet sent from a user in a system in which the user may be connected to multiple networks simultaneously, the apparatus including:
-
means for extracting a source address from the packet; means for finding a per-user routing table corresponding to said source address, said per-user routing table unique to the user and containing entries corresponding to one or more currently accessible networks for the user and the range of network addresses corresponding to said currently accessible networks; means for extracting a destination address from the packet; and means for routing the packet to a matching network if said destination address is contained within one of said ranges of network addresses for said currently accessible networks. - View Dependent Claims (8, 9)

10. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method for routing a packet sent from a user in a system in which the user may be connected to multiple networks simultaneously, the method comprising:
-
extracting a source address from the packet; finding a per-user routing table corresponding to said source address, said per-user routing table unique to the user and containing entries corresponding to one or more currently accessible networks for the user and the range of network addresses corresponding to said currently accessible networks; extracting a destination address from the packet; and routing the packet to a matching network if said destination address is contained within one of said ranges of network addresses for said currently accessible networks. - View Dependent Claims (11, 12)
