Ilan Hamami: Method of port/link redundancy in an ATM switch. 3Com Corporation, David J Wilson Sonsini Goodrich & Rosati Weitz, September 28, 1999: US05959972 (101 worldwide citation)

A method for implementing redundancy of both links and ports between two switches, e.g., ATM switches. A redundant link connection between two ATM switches is constructed using two separate parallel communication links connected between separate ports on each of the switches. One communication link ...

Ilan Hamami: Method of VCC/VPC redundancy for asynchronous transfer mode networks. 3Com Corporation, Howard Zaretsky, David J Weitz, Wilson Sonsini Goodrich & Rosati, April 24, 2001: US06222820 (44 worldwide citation)

A method of selectively providing redundancy on a dynamic basis to end users that request it. The method establishes both a primary and a redundant connection for each connection requested to be redundant. The redundancy method of the present invention has application to PNNI networks and to any pub ...

Ilan Hamami: System for probing switched virtual circuits in a connection oriented network. 3Com Corporation, Howard Zaretsky, McDonnell Boehnen Hulbert & Berghoff, April 6, 2004: US06717914 (19 worldwide citation)

A system for probing one or more SVCs that enables a network manager station to setup a probe event in advance before a SVC is created. Upon the creation of the SVC, the data is captured and sent to the network management station without any further intervention required. In a first stage, a SVC ori ...

Ilan Hamami: Caching system using cache indexes for call group data of call requests in ATM network devices. 3Com Corporation, Howard Zaretsky, David J Weitz, Wilson Sonsini Goodrich & Rosati, January 30, 2001: US06182193 (13 worldwide citation)

A signaling cache suitable for use in networks, such as ATM networks, that utilize signaling in establishing calls. The invention functions to greatly reduce the amount of call processing required for calls that have been previously received and processed by the switch. The signaling cache can be im ...

Ilan Hamami: Static switched virtual circuits in a connection oriented network. 3Com Corporation, Howard Zaretsky, November 26, 2002: US06487168 (9 worldwide citation)

A system for establishing static SVCs (i.e. permanent SVCs) whereby the results of the signaling/routing protocol generated when the network is first brought up are stored in a ‘permanent SVC’ memory. The results of the signaling/protocol that were previously stored are restored from memory in the e ...

Ilan Hamami: Method of providing a signaling qualification function in a connection oriented network. 3Com Corporation, Howard Zargtsky, April 20, 2004: US06724723 (4 worldwide citation)

A method of providing a qualification function and associated action function to be performed for a connection request or a group of connection requests. The invention is applicable to situations wherein it is desirable for the network to perform a specific action before, during and/or after the est ...
