Patent number: 9197550Abstract: A method and corresponding device for determining forwarding rule for data packet in Virtual Private LAN Service with Provider Backbone Bridge (PBB-VPLS) network are disclosed. In the method, a value in a backbone service instance identifier (I-SID) field of the received data packet is firstly examined, then a virtual split horizon group corresponding to the data packets is determined based on the I-SID value, wherein the virtual split horizon group defines a forwarding rule for the data packets between different pseudo wire ports of the PBB-VPLS network. With the dynamic split horizon group, the method dynamically adapts to different forwarding rules for multiple I-VPLS instances with different tree topologies, and is capable of supporting multiple I-VPLS instances with different root sites and tree topologies in one B-VPLS instance, thereby ensuring the stability of the backbone network and reducing the network operation cost.Type: GrantFiled: December 17, 2009Date of Patent: November 24, 2015Assignee: Alcatel LucentInventors: Lixin Zhang, Duan Chen, Lijun Chen

Patent number: 9148223Abstract: The present disclosure provides hybrid packet-optical private network systems and methods for a private and dedicated multi-point Ethernet Private Local Area Network (EPLAN). The network systems and methods include a Layer 1 infrastructure service with the inclusion of reserved, dedicated packet switch capacity upon which clients can build their personal, private packet networks. In the systems and methods described herein, packet networking methods are not used to partition the isolated LAN connectivity. Instead, dedicated Ethernet Private LANs (EPLs) are defined between dedicated virtual switching instances (VSIs) that are defined, as necessary, within larger packet-optical switches. Each VSI is partitioned from the remainder of its packet switch fabric as a dedicated, private resource for a specific EPLAN. A packet network is then built by the customer on top of the private EPLAN bandwidth and operated as an isolated, private network with no influence by other carrier's network resources.Type: GrantFiled: May 20, 2013Date of Patent: September 29, 2015Assignee: Ciena CorporationInventor: Loudon T.

Patent number: 9137194Abstract: A system and method for associating users with a micro-community that is relevant to an object reference. The object reference is anything that can be perceived either physically or conceptually, such as a location, a document, a calendar entry, a document, a news feed, a biometric key, an image, a news feed, etc. A micro-community engine identifies users who are associated explicitly with the object reference as well as people who would be interested in the object implicitly and associates them with a micro-community. The micro-community engine provides an intuitive and flexible means for communication between members of the micro-community.Type: GrantFiled: March 19, 2014Date of Patent: September 15, 2015Assignee: Google Inc.Inventors: Christopher Wren, Nadav Aharony
