Publication number: 20150326480Abstract: A method for providing a conditional action following TCAM lookup is disclosed. The method for providing a conditional action following TCAM lookup includes obtaining data; generating a lookup key from the data; performing a TCAM lookup using the key; and in the event the TCAM lookup generates a match, then performing an test to determine if there is exists a condition associated with the action associated with that match, and in the event the there is a condition, evaluating said condition associated with the action of that match entry; and in the event that said condition is satisfied, then performing a conditional action. The data may be from a communications packet header, the condition evaluation may be one of packet length or Time to Live (TTL) value, and the action taken may be one of dropping or forwarding a communications packet. The method for providing a conditional action following TCAM lookup is particularly useful for reducing the quantity of entries in a TCAM of TCAM filters known in the art.Type: ApplicationFiled: May 7, 2014Publication date: November 12, 2015Inventors: Andrew Dolganow, Mark French

Publication number: 20150172166Abstract: Virtual connection route selection apparatus and techniques are disclosed. At a communication traffic routing apparatus, metric information associated with multiple different routes for a virtual connection, such as a PseudoWire, toward a destination is collected. The metric information may be collected from one or more remote route computation elements capable of computing routes for virtual connections between the routing apparatus and other routing apparatus over an underlying communication system, or during actual establishment of the virtual connections, for example. An initial or re-optimized route for a virtual connection can then be selected at the routing apparatus based on the collected metric information. In some embodiments, although the virtual connection routes are paths computed by Path Computation Elements (PCEs), actual path selection decisions are distributed to routers.Type: ApplicationFiled: February 23, 2015Publication date: June 18, 2015Applicant: ALCATEL LUCENTInventors: MUSTAPHA AISSAOUI, ANDREW DOLGANOW

Patent number: 8837287Abstract: Various exemplary embodiments relate to a system and related method for transmission of content over a telecommunications network. The system may include a deep packet inspection (DPI) device configured to perform DPI to identify an application associated with the new flow, determine an amount of bandwidth required for the application, and determine a current amount of bandwidth used by the subscriber. The DPI device may then determine a total amount of bandwidth used by the subscriber.

Patent number: 8681605Abstract: An Ethernet protection and loadsharing capability is provided. The Ethernet protection and loadsharing capability enables co-existence of both protection and loadsharing for an Ethernet tunnel, having a plurality of associated Ethernet paths, between first and second Ethernet switches. The first Ethernet switch receives configuration information associated with the Ethernet tunnel between the first and second Ethernet switches, and processes the configuration information for causing the first Ethernet switch to associate the Ethernet paths of the Ethernet tunnel with an Ethernet tunnel endpoint object associated with an Ethernet tunnel. The first Ethernet switch, upon receiving traffic intended for the second Ethernet switch, propagates the traffic from the first Ethernet switch toward the second Ethernet switch via at least a subset of the Ethernet paths of the Ethernet tunnel using protection and/or loadsharing.Type: GrantFiled: January 10, 2011Date of Patent: March 25, 2014Assignee: Alcatel LucentInventors: Florin Balus, Andrew Dolganow, Kajal Saha, Georges Chung Kam Chung

Patent number: 8289864Abstract: Based on application information received from a Deep Packet Inspection (DPI) device, a Radio Network Controller (RNC) or similar device may select a dormancy timer value to optimize the use of network resources. In particular, the RNC may set an additional dormancy timer based on a default value or a rough determination of the application by examining port numbers. After the DPI device has received a sufficient number of packets to identify the underlying application, the DPI device may then propagate the application information to the RNC. Based on this application information, the RNC may determine the most efficient dormancy timer and modify the value of the default timer based on this determination.Type: GrantFiled: August 28, 2008Date of Patent: October 16, 2012Assignee: Alcatel LucentInventors: Andrew Dolganow, Steven Edward Morin

Patent number: 8204915Abstract: Various exemplary embodiments disclose an apparatus and method for generating a database that maps metadata to peer-to-peer (P2P) content and, more particularly, to a database that an Internet Service Provider (ISP) can build to correlate metadata with P2P traffic. The database may collect metadata having a key that uniquely corresponds to particular P2P content. An ISP may use the database to identify malware in P2P files and tag P2P traffic that seeks to exchange material in violation of applicable copyright laws.Type: GrantFiled: February 13, 2009Date of Patent: June 19, 2012Assignee: Alcatel LucentInventors: Andrew Dolganow, Steve Morin, David Maxwell

Patent number: 8179846Abstract: Based on application information received from a DPI device, a downstream device, such as a Radio Network Controller (RNC), optimally implements a dormancy timer policy for short-lived applications, such as email and MMS. In particular, the RNC may initially use a large value for the dormancy timer for these applications. When the RNC receives an indication of the end of the application from the DPI device, the RNC may terminate the connection, thereby immediately freeing up resources. Alternatively, should the DPI device fail to recognize the end of the application, the initial dormancy timer serves as a fail-safe, such that the radio network resources are still released for allocation to another device in the radio network.Type: GrantFiled: September 8, 2008Date of Patent: May 15, 2012Assignee: Alcatel LucentInventors: Andrew Dolganow, Jason Rusmisel

Patent number: 8159941Abstract: In various exemplary embodiments, a Deep Packet Inspection device is integrated into a provider edge router associated with a user agent client or provided externally. The DPI device monitors the exchange of packets between an originating proxy and a user agent client and inspects the packets to identify SIP control messages. By monitoring the messages exchanged between the two devices, the DPI device may determine the type of application, desired QoS, source, destination, and other information related to the connection. Using this information, the router may then access a policy database to determine whether there is a QoS policy for the application and/or user. Based on this determination, the router may initiate network reservation for an anticipated data flow or store the information so the flow of packets can be remarked as the packets arrive. Accordingly, in various exemplary embodiments, the edge router is aware that QoS should be granted.Type: GrantFiled: August 28, 2008Date of Patent: April 17, 2012Assignee: Alcatel LucentInventors: Andrew Dolganow, Steven Edward Morin
