Patent number: 6760309Abstract: An apparatus for and a method of dynamically prioritizing packets over a packet based network. Packets are dynamically prioritized on the basis of their ‘time to live’ in the network as they travel from one network entity to another. Packets are assigned a priority in accordance with how ‘old’ or ‘young’ they are. Packets with a relatively long time left to live are assigned lower priority then those with relatively little time left to live. A time to live (TTL) field is added to the packet as it travels from one network entity to another. The contents of the time to live (TTL) field represents how ‘young’ or ‘old’ the packet is and conveys the time left before the packet is no longer of any use. Each network entity that receives the packet with a TTL field, subtracts from it the time the packet spends passing through that entity. The field decreases as it hops from network entity to entity until it reaches its destination or is discarded.Type: GrantFiled: March 28, 2000Date of Patent: July 6, 2004Assignee: 3Com CorporationInventors: Haim Rochberger, Gad Azriel, Sarit Shani Natanson

Patent number: 6643289Abstract: A method of notification and handling of device status changes in MPOA enabled ATM based networks. In a first method notification of changes in device status configuration are provided by selectively releasing one or more Data Direct VCs that were previously established be LECs connecting MPOA Servers and MPOA Clients. An MPOA Server, upon detecting a change to its device configuration status, releases the Data Direct VCs connecting its associated LEC to known MPSs and MPCs that are neighbors to it. All MPOA devices for which a Data Direct VC was released delete all LE_ARP cache entries associated with the ATM destination of the released Data Direct VC. In a second method, each MPOA device periodically sends keep alive messages as targetless LE_ARP messages having a time to live TLV appended. An MPOA device receiving the keep alive message, refreshes (i.e., restarts) a validation timer for each association made by the corresponding MPOA identification TLV.Type: GrantFiled: December 29, 1999Date of Patent: November 4, 2003Assignee: 3Com CorporationInventors: Sarit Shani Natanson, Lior Katzri, Benny Gershon, Ronit Aizicovich

Patent number: 6633542Abstract: A method of controlling the route used for a flow in an environment comprising a default routing path and a shortcut path in an MPOA enabled ATM based network. A data field is added to the Ingress Cache table in the Ingress MPOA Client (I-MPC) to indicate whether the flow is to be routed through an MPOA shortcut towards the Egress MPOA Client (E-MPC) or is to be routed through the default path towards the Ingress MPOA Server (I-MPS). A first embodiment comprises a method of controlling the routing of a data flow from a source to a destination for security purposes. A second embodiment comprises a method of load sharing a plurality of data flows. A third embodiment comprises a method of learning about past MPOA resolution successes and failures and utilizing past establishment history to bypass the MPOA resolution process.Type: GrantFiled: December 29, 1999Date of Patent: October 14, 2003Assignee: 3Com CorporationInventors: Sarit Shani Natanson, Benny Gershon, Lior Katzri

Patent number: 6611525Abstract: An apparatus for and a method of learning MAC addresses in a Local Area Network (LAN) Emulation (LANE) network implemented over an Asynchronous Transfer Mode (ATM) network. The LEC or LES is adapted to detect when the ATM address associated with a MAC address is no longer valid. Once an invalid ATM address is detected the existing entry can be updated or deleted. A LEC_ID table holding LEC_ID to ATM address bindings is created. Each frame received by the LEC is sniffed in order to find mismatches between the ATM address and the LEC_ID. Optionally, an LE_ARP request message can be forwarded to the LES for learning the new binding. If the MAC address is not found in the LE_ARP table, an entry can be created and added to the table. In another embodiment, the LES is adapted to detect when the MAC to ATM address binding stored in the internal LE_ARP cache is no longer valid. The LE_ARP table is populated by examining LE_ARP request and response sent and received by the LEC.Type: GrantFiled: October 7, 1999Date of Patent: August 26, 2003Assignee: 3Com CorporationInventors: Sarit Shani Natanson, Ronit Aizicovich, Golan Schzukin, Haim Rochberger

Patent number: 6606321Abstract: A method of establishing calls between an ingress MPC (the calling party) and an egress MPC (the called party) in MPOA enabled ATM based networks. The call establishment method utilizes the call request SETUP, CONNECT and CONNECT_ACK messages in creating the shortcut VCC between ingress and egress MPCs. The calling party is adapted to send a READY_IND message in a reliable manner to the called party indicating that it is ready to receive frames over the shortcut VCC. The called party starts sending data over the shortcut VCC only when it knows that the calling party is ready. The called party knows the calling party is ready upon receipt of a READY_IND message or at least one data frame on the shortcut VCC. The calling party knows that the called party is ready to receive frames when it receives the CONNECT message. Since the READY_IND message sent by the calling party may get lost, the calling party is adapted to re-send the READY_IND message repeatedly until it is certain the called party has received it.Type: GrantFiled: December 29, 1999Date of Patent: August 12, 2003Assignee: 3Com CorporationInventors: Sarit Shani Natanson, Lior Katzri, Benny Gershon, Dror Goldstein

Patent number: 6594235Abstract: A method of triggering reroutes in an ATM network based on a call optimization value being reduced beyond a predefined threshold. The method utilizes a signaling element in the SETUP message called a PNNI optimization reservation signaling element that includes an optimization type, value and percentage. A switch accumulates the optimization value and passes this value to the next node along the path. In addition, the hardware in the node is configured to measure and monitor the optimization value. The optimization value is monitored for changes that exceed the predefined optimization percentage. When this is detected, the software calculates a reroute. If the new route is better than the current route and is within the optimization percentage constraints, a reroute is performed using the newly calculated route. The reroute procedure provided by the ATM Forum can be used to implement the reroute.Type: GrantFiled: April 28, 1999Date of Patent: July 15, 2003Assignee: 3Com CorporationInventors: Haim Rochberger, Alexander Or, Arcady Chernyak, Sarit Shani Natanson

Patent number: 6577653Abstract: An apparatus for and a method of establishing a connection between a source and destination node using multiple parallel paths. To establish a connection, bandwidth capacity on one or more parallel paths are aggregated and combined to form a route having a bandwidth larger than any single path. A technique similar to inverse multiplexing is used at the source end to split the cell stream into multiple parallel paths. At the destination end, the parallel multiple cell streams are inverse demultiplexed and the multiple cell streams combined into a single cell stream. The parallel routes are established by building parallel VCCs for the same call via the network. The ATM signaling process at the source and destination nodes is modified to accommodate multiple VCCs. In addition, the hardware at each source and destination node is configured to perform the inverse and inverse demultiplexing.Type: GrantFiled: April 28, 1999Date of Patent: June 10, 2003Assignee: 3Com CorporationInventors: Haim Rochberger, Sarit Shani Natanson, Michael Gorokhovsky
