Patent number: 6269404Abstract: Network traffic management is achieved based on automatically setting up a plurality of virtual networks (VNETs) within a single large virtual LAN. Multicast/broadcast traffic is confined to the VNET of the source, without imposing constraints on layer two addressing within the virtual LAN. VNETs are domains of users of a virtual LAN which include members of logical networks defined at layer three or higher. One method includes transferring a multi-destination packet originating from a particular node in the virtual LAN by tunnelling across a connectionless backbone network to a virtual net server. The virtual net server translates the multi-destination packet to a plurality of tunneled messages identifying nodes authorized to receive multi-destination packets from members of the particular VNET which originated the packet. The tunneled messages are then forwarded from the virtual net server to the authorized nodes.Type: GrantFiled: January 5, 1999Date of Patent: July 31, 2001Assignee: 3Com CorporationInventors: John H. Hart, W. Paul Sherer

Patent number: 6028862Abstract: The present invention provides a method and an apparatus for facilitating high bandwidth transmissions of data through a computer network. The invention uses communications through a routed network, such as the Internet, to establish a communication pathway through a connection-oriented network, such as an ATM or a frame relay network. This technique effectively exploits the universal addressing structure of routed networks, such as the Internet, to establish high bandwidth connections through connect-oriented networks. The present invention also facilitates selection of a connection-oriented network for data transmissions from a plurality of connection-oriented networks based upon parameters such as availability and costs. One embodiment of the present invention facilitates connections through mixed connection-oriented and routed networks, as well as through multicast networks. Another embodiment multiplexes several flows of data into a single connection through a connection-oriented network.Type: GrantFiled: May 8, 1997Date of Patent: February 22, 2000Assignee: 3Com CorporationInventors: Steven P.

Multicast/broadcast traffic is confined to the VNET of the source, without imposing constraints on layer two addressing within the virtual LAN. VNETs are domains of users of a virtual LAN which include members of logical networks defined at layer three or higher. One method includes transferring a multi-destination packet originating from a particular node in the virtual LAN by a point-to-point path to a virtual net server. The virtual net server translates the multi-destination packet to a plurality of directed messages identifying nodes authorized to receive multi-destination packets from members of the particular VNET which originated the packet. The directed messages are then forwarded from the virtual net server to the authorized nodes. This way, multi-destination packets, such as advertisement or discovery packets, are confined to a single VNET.Type: GrantFiled: July 14, 1995Date of Patent: May 12, 1998Assignee: 3 Com CorporationInventor: John H.

Patent number: 5590285Abstract: DLL devices are built with multiple MAC address instead of a single MAC address, and provide a multiple virtual DLL interfaces to the upper layers (3-7) in a computer. This results in a new class of multi-function computers for attachment to a network system which take advantage of the multiple virtual DLL interfaces, to increase performance of the respective functions executed by the computer. Thus, a new network interface control apparatus and a new class of multi-function computer systems for attachments to networks are provided. The memory in the medium access control device stores a plurality of additional network addresses in addition to the assigned network addresses. The address filtering logic includes circuits responsive to the additional network addresses, such as logic for blocking a particular frame on at least one of the plurality of data channels when the source and destination address of a particular frame are found in the additional addresses stored in the memory.Type: GrantFiled: August 9, 1995Date of Patent: December 31, 1996Assignee: 3Com CorporationInventors: Jeffrey Krause, Niles E.

Patent number: 5583997Abstract: A system for interconnecting networks transparently extends the multiprotocol routing functionality of a router across a communication link to a remote LAN, while requiring a device on the remote LAN which operates independent of the higher layer protocol suites. A boundary router, having a local routing interface coupled to the first network, and a remote routing interface coupled to the communication link, provides the higher level protocol suite services for routing frames of data to terminals in the first and second networks. A routing adapter extends the remote routing interface of the boundary router transparently across the communication link to the second network.Type: GrantFiled: June 1, 1995Date of Patent: December 10, 1996Assignee: 3Com CorporationInventor: John H.
