20090304000 | OUTBOUND TRANSMISSION OF PACKET BASED ON ROUTING SEARCH KEY CONSTRUCTED FROM PACKET DESTINATION ADDRESS AND OUTBOUND INTERFACE - A method is described that involves associating an outbound packet with a first network interface and constructing a search key from an identifier of the first network interface and the outbound packet's destination address. The method further entails submitting the search key to a routing function where the routing function identifies the outbound packet's next hop address. The method also involves transmitting the outbound packet to a node identified by the next hop address from the first network interface. | 12-10-2009 |
20090304001 | SOURCE ADDRESS BASED ROUTING PROCESS - A method is described that entails assigning a source network address to an outbound packet, associating the outbound packet with a network service and identifying a first network interface associated with the network service. The method further entails inquiring into and confirming that the first network interface is associated with the source network address. The method further entails constructing a search key from an identifier of the first network interface and the outbound packet's destination address. The method further entails submitting the search key to a routing function, the routing function providing the outbound packet's next hop address. The method further entails transmitting the outbound packet to a node identified by the next hop address from the network interface. | 12-10-2009 |
20090304005 | ROUTING TABLE LOOKUP ALGORITHM EMPLOYING SEARCH KEY HAVING DESTINATION ADDRESS AND INTERFACE COMPONENT - A routing table lookup algorithm is described that, for a first outbound packet, performs a first route lookup into the routing table with a first search key that includes the first packet's destination address and a first network interface identifier, and, for a second outbound packet, performs a second route lookup into the routing table with a second search key that includes the second outbound packet's destination address but does not include any network interface identifier. | 12-10-2009 |
20090304006 | ROUTING TABLE BUILD ALGORITHM FOR A ROUTING TABLE THAT USES A SEARCH KEY CONSTRUCTED FROM PACKET DESTINATION ADDRESS AND OUTBOUND INTERFACE - A method is described that involves, in view of a first default entry for a first subnet that is reachable through a first network service, where the first default entry has a numeric destination value, and in view of a second default entry for a second subnet that is reachable through a second network service, wherein the second default entry has the numeric destination value, sorting the first and second default entries by deciding that the first network service is ranked higher than the second network service. The method further involves configuring the first default entry within a routing table to have the numeric destination and not an interface component within the first default entry's search term, and, configuring the second default entry within the routing table to have the numeric destination and the second network service's interface component within the second default entry's search term. | 12-10-2009 |
20110222542 | SOURCE ADDRESS BASED ROUTING PROCESS - A method is described that entails assigning a source network address to an outbound packet, associating the outbound packet with a network service and identifying a first network interface associated with the network service. The method further entails inquiring into and confirming that the first network interface is associated with the source network address. The method further entails constructing a search key from an identifier of the first network interface and the outbound packet's destination address. The method further entails submitting the search key to a routing function, the routing function providing the outbound packet's next hop address. The method further entails transmitting the outbound packet to a node identified by the next hop address from the network interface. | 09-15-2011 |
20120057596 | Outbound Transmission Of Packet Based On Routing Search Key Constructed From Packet Destination Address And Outbound Interface - A method is described that involves associating an outbound packet with a first network interface and constructing a search key from an identifier of the first network interface and the outbound packet's destination address. The method further entails submitting the search key to a routing function where the routing function identifies the outbound packet's next hop address. The method also involves transmitting the outbound packet to a node identified by the next hop address from the first network interface. | 03-08-2012 |
20150350071 | SELECTING AN INTERFACE FOR PACKET ROUTING BASED ON APPLICATION-LAYER DATA - The disclosed embodiments relate to a system for selecting an interface for routing an outbound packet. During operation, the system receives an outbound packet to be routed to a destination address. Next, the system obtains application-layer data associated with the outbound packet, including one or more of a process identifier, an application identifier and a user identifier. The system then selects an interface through which to route the outbound packet based on the application-layer data, and uses the selected interface to route the outbound packet. | 12-03-2015 |
