Patent number: 9118502Abstract: The invention is directed to providing a method and system for automatically determining a root cause of a failure in a packet switching telecommunications network using IP/MPLS protocols and having Virtual Private Network (VPN) services such as VLL, VPLS, VPRN.Type: GrantFiled: June 16, 2009Date of Patent: August 25, 2015Assignee: Alcatel LucentInventors: Denis Armand Proulx, Reda Laichi

Patent number: 8326976Abstract: The invention is directed to configuring an application management reporting service for managing a networked application carried over a WAN service without requiring knowledge of a network operator's infrastructure that is providing the WAN service. This capability aims at providing an abstraction from both the architecture of the operator's network and the technical details of its QoS management.Type: GrantFiled: June 30, 2009Date of Patent: December 4, 2012Assignee: Alcatel LucentInventors: Denis Armand Proulx, Glenn Michael Chenier

Patent number: 8040822Abstract: The invention is directed to configuring services in a packet switching network. Embodiments of the invention group existing service policies configured on network routers into policy groups, thereby enabling better management of service policies and policy overrides. This functionality can be useful for identifying redundant policies that may be eliminated by reconfiguring one or more of the network routers to reduce the overall network-wide number of policies, as well as provisioning new services in a manner that efficiently uses existing policies.Type: GrantFiled: June 4, 2009Date of Patent: October 18, 2011Assignee: Alcatel LucentInventors: Denis Armand Proulx, Reda Laichi

Patent number: 8000264Abstract: The invention is directed to managing changes to a configuration of routers connected in a ring network architecture. Embodiments of the invention alleviate risks to services carried over a ring of IP/MPLS routers when configuration changes are made to the ring, such as inserting a router into, or removing a router from, the ring. To that end, embodiments of the invention automate some steps of such a configuration change operation that were previously performed manually, and coordinate those steps with other steps of the operation using a procedure stored as instructions on a computer readable media and executed by a computer system in order to effect and validate a correct sequencing of the steps.Type: GrantFiled: April 29, 2009Date of Patent: August 16, 2011Assignee: Alcatel LucentInventors: Denis Armand Proulx, Patricia Michaud

Patent number: 7961599Abstract: The invention is directed to providing pseudowire tunnel redundancy for VPLS and VLL services in the form of automatic protection switching of the service from a primary pseudowire tunnel to a backup pseudowire tunnel upon detection of a failure affecting the primary pseudowire tunnel. Embodiments of the invention monitor event notifications reported by a network management entity for an indication of a failure affecting the primary pseudowire tunnel; and responsive to detecting the indication, switch a service carried by the primary pseudowire tunnel to the backup pseudowire tunnel. Such event notifications include those corresponding to any of provider edge routers, interface ports, service access points, spokes, and tunnel endpoints that are related to operation of the primary pseudowire tunnel.Type: GrantFiled: March 3, 2009Date of Patent: June 14, 2011Assignee: Alcatel LucentInventor: Denis Armand Proulx

Publication number: 20100235914Abstract: The invention is directed to detecting an attempt of an intruder system to participate in a virtual Layer-2 service provided over a packet switching network. Embodiments of the invention monitor operational status of an interface port of a PE router to which a CE router is communicatively coupled for providing the virtual Layer-2 service, determine, consequent to a change in said status, whether information that should relate to the CE router has changed; and thereby, in the affirmative, interpret said change to indicate that an intruder system has attempted to participate in the virtual Layer-2 service. Advantageously, this capability is complementary to other security measures such as MAC filters and Anti-spoofing filters that depend on the content of data packets exchanged between the CE and PE routers and not on the operational status of communicative connections between them.Type: ApplicationFiled: March 13, 2009Publication date: September 16, 2010Applicant: ALCATEL LUCENTInventor: Denis Armand Proulx

Patent number: 7453888Abstract: A method and human-machine interface for backbone Virtual Local Area Network (VLAN) provisioning in bridged networking environments are provided. The method includes steps of provisioning backbone VLAN support on every backbone data transport trunk and by extension of every stackable data trunk port in the associated data transport network. The human-machine interface enables an operator to expediently effect VLAN provisioning abstracting the intricacies of the data transport network over which VLAN services are provisioned. Advantages are derived from backbone VLAN provisioning independent of an underlying in-use active spanning-tree topology. In particular backbone VLANs are provisioned over spanning-tree stand-by designated backbone data transport trunk links and therefore preprovisioned in the case of spanning-tree re-configuration. Customer VLANs are mapped onto backbone VLANs ensuring data traffic differentiation, and providing standard VLAN identifier portability.Type: GrantFiled: August 27, 2002Date of Patent: November 18, 2008Assignee: Alcatel LucentInventors: Attaullah Zabihi, Denis Armand Proulx, Macmohana Singh Virdy, Chuong Ngoc Ngo, Andre Neil Dominic Jacob

Publication number: 20040042416Abstract: A method of automatic discovery of existing Virtual Local Area Network (VLAN) configuration in a bridged network is provided. The method includes steps of: reconciling a data transport infrastructure in a data transport network; reconciling data transport node configurations; gathering nodal VLAN configurations from all data transport nodes; correlating the data transport infrastructure information, node configuration information and nodal VLAN configurations; and extracting network-wide provisioned VLAN configuration subject to discrepancies. A VLAN auto-discovery application tool having human-machine interface is also provided. The VLAN auto-discovery application tool is operable to initiate the VLAN auto-discovery process and to display the discovered VLAN configuration. The VLAN auto-discovery human-machine interface also is adapted to display a VLAN-specific provisioning status.Type: ApplicationFiled: August 27, 2002Publication date: March 4, 2004Inventors: Chuong Ngoc Ngo, Andre Neil Dominic Jacob, Attaullah Zabihi, Denis Armand Proulx

Publication number: 20040044754Abstract: A method and human-machine interface for Virtual Local Area Network (VLAN) provisioning in bridged networking environments are provided. The method includes steps of provisioning VLAN support for each customer VLAN on every data transport trunk and by extension of every data trunk port in the associated data transport network. The human-machine interface enables an operator to expediently effect VLAN provisioning abstracting the intricacies of the data transport network over which VLAN services are provisioned. Advantages are derived from VLAN provisioning independent of an underlying in-use active spanning-tree topology. In particular customer VLANs are provisioned over spanning-tree stand-by designated data transport trunk links and therefore pre-provisioned in the case of spanning-tree re-configuration. Operator VLAN provisioning tasks are lessened via provisions for the selection of all data transport trunk links/ports in the data transport network.Type: ApplicationFiled: August 27, 2002Publication date: March 4, 2004Inventors: Macmohana Singh Virdy, Moise Gaspard, Denis Armand Proulx, Georges Jabbour, Imad Alam Ansari
