Patent number: 9225622Abstract: Echo messaging for operation, administration, and management of a service-based distribution path and associated services are disclosed. Service-based distribution paths or transport tunnels include services mapped or bound to a path associated with the transport tunnel. Echo messaging provides OAM capabilities to monitor the operational state of a service-based distribution path, including determining configuration, connectivity, and other characteristics of the path and associated services that transport data. OAM functions provided by echo messaging enable OAM functions despite service volume along a core network, path or set of paths.Type: GrantFiled: December 23, 2008Date of Patent: December 29, 2015Assignee: Alcatel LucentInventors: Joe Regan, Vach Kompella, Wenao Hu

Patent number: 8626883Abstract: Inserting an address used for performing such OAM functions in an efficient way that is transparent to a customer or service using the network path is disclosed. An indication is received that a source address reserved for OAM use should be inserted into a forwarding database associated with a provider network node, such as a provider edge device, that receives the indication. The address is inserted into a forwarding database as an address that is owned by the provider network node and reserved for OAM use. One or more other nodes associated with a service with which the OAM address is associated may be notified that the OAM address is associated with the provider network node that owns the OAM address.Type: GrantFiled: May 6, 2010Date of Patent: January 7, 2014Assignee: Alcatel LucentInventors: Vach Kompella, Joe Regan, Wenao Hu

Patent number: 7558194Abstract: Loss of connectivity on a mesh or virtual service (e.g., VPLS) may be restored by “stitching” a healing path between an affected node and another node on the mesh. Connectivity may be restored by “healing” or constructing an alternate path or connection between the affected node and the mesh. Unidirectional and bidirectional healing may be used to establish an alternate path between the affected node and the mesh. Additionally, removing pseudowire connections between the affected node and the mesh may be performed, while establishing a spoke connection to an advertised, available router to create a new connection or “stitch” together existing connections.Type: GrantFiled: April 27, 2004Date of Patent: July 7, 2009Assignee: Alcatel-Lucent USA Inc.Inventors: Joe Regan, Vach Kompella
