Patent number: 8767565Abstract: Apparatus, method, and storage medium for testing a network. A network card may include four transmit engines and four receive engines to respectively generate and process packets at a data rate of 10 GHz. The network card may be configured in a first mode to also include four 10 GHz network interface units coupled to respective ones of the four 10 GHz transmit engines and the four 10 GHz receive engines. The network card may be configured in a second mode to also include a coherent multiplexer to combine packets generated by the four 10 GHz transmit engines into test traffic at a 40 GHz data rate, a packet distribution engine to accept packets at a 40 GHz data rate and distribute the accepted packets between the four 10 GHz receive engines, and a 40 GHz network interface unit coupled to the coherent multiplexer and the packet distribution engine.Type: GrantFiled: September 13, 2011Date of Patent: July 1, 2014Assignee: IxiaInventors: John Dalmau, Victor Alston, Gerald Pepper, Viet Quoc Tran

Patent number: 8614955Abstract: There are disclosed methods and a packet receiver for testing a network. A packet may be received from the network at a port unit. The port unit may ignore the received packet if the received packet does not contain a valid test signature. When the received packet contains a valid test signature, the port unit may determine if the port unit is an expected destination for the received packet. When the port unit is not an expected destination for the received packet, a misdirected packet counter may be incremented. When the port unit is an expected destination for the received packet, test data may be extracted from the received packet.Type: GrantFiled: September 22, 2009Date of Patent: December 24, 2013Assignee: IxiaInventors: Noah Gintis, Alok K. Srivastava, Victor Alston

Patent number: 8537839Abstract: There is disclosed a port unit and methods for testing a network. The port unit may include a traffic generator, traffic receiver, and a port processor. The traffic generator may include a memory that stores data defining a plurality of packet streams. The port processor may store label tracking data associating a plurality of label condition sets with one or more respective locations within the traffic generator memory. When a control packet associating a MPLS label with a specific label condition set is received via the traffic receiver, the port processor may store the MPLS label in one or more traffic generator memory locations associated with the specific label condition set in accordance with the stored label tracking data.Type: GrantFiled: August 30, 2010Date of Patent: September 17, 2013Assignee: IxiaInventors: Noah Gintis, Alok Srivistava, Victor Alston

Patent number: 8417478Abstract: There is disclosed a system and method for network test conflict checking. The method may be performed by a network testing system and may be implemented as software. The method may include receiving user selected test features and user selected hardware for a network test. When receiving user selected features, incompatible features are made unselectable by reference to a feature database. A compatibility check is performed by referring to a hardware database and a feature database. Suggestive corrective changes may be provided to a user or automatically made to the selected features and/or selected hardware. The network test is written to hardware when the compatibility test is successful.Type: GrantFiled: September 23, 2010Date of Patent: April 9, 2013Assignee: IxiaInventors: Noah Gintis, Alok Srivastava, Victor Alston
