| 20080232360 | Session Admission Control Method and Apparatus - For efficient and fast admission control with respect to a new session and for exchange of data stream packets between an edge router ( | 09-25-2008 |
| 20080291822 | Method and Arrangement for Failure Handling in a Network - The invention relates to failure handling in a tree sructure network (NW | 11-27-2008 |
| 20100054157 | Method And Apparatus For Network Tree Management - There is disclosed a manner of managing the active topology, that is the scheme for forwarding data, in a computer network such as an Ethernet local area network. A root bridge is selected from a plurality of bridges in the network; the root bridge calculating at least one spanning tree from a topology database that has been populated by bridge neighbor information gleaned from link state advertising messages. The root bridge may also calculate an alternate topology for implementation in the event a failure condition that affects the primary spanning tree is detected. The root bridge then advertises the spanning tree and remotely configures the port states of the bridges in the spanning tree through tree advertising messages that the bridges are arranged to process and set their ports accordingly. | 03-04-2010 |

| 20100165884 | Ethernet Spanning Tree Provision - A method and apparatus for providing a Spanning Tree to nodes on an Ethernet network. A Spanning Tree topology is calculated, and a Resource Reservation Protocol Traffic Extension path message is generated. The path message contains at least a part of the Spanning Tree topology. The path message is sent to bridges on the Ethernet network. The bridge nodes that receive the path message configure their port states depending on the information contained in the path message, and may also configure port Virtual Local Area Network membership. | 07-01-2010 |
| 20110013640 | METHOD AD APPARATUS FOR ETHERNET PROTECTION WITH LOCAL RE-ROUTING - A method is provided for use at a first node of a network. The first node (B) has an input path for receiving Ethernet frames destined for a second node of the network. The first node (B) also has a first output (working) path for forwarding the received Ethernet frames towards the second node. A failure along the first output (working) path is detected at the first node. Following such failure detection, the received Ethernet frames are caused, at the first node, to be re-routed along a second output (backup) path, different to the first output (working) path, towards the second node. The re-routing is performed by using (e.g. referring to and/or changing) respective indications (VLAN | 01-20-2011 |
| 20110044171 | CONGESTION HANDLING IN MULTICAST NETWORKS - The invention relates to techniques for traffic handling in congestion situations in a point-to-multipoint (‘PTM’) enabled network. A method embodiment of the inventive technique is performed in an egress node of the network and comprises the steps of detecting marked packets, the marking being indicative of a congestion situation in a core node of the PTM-enabled network; selecting, based on the detected markings, a particular PTM flow from one or more PTM flows passing the egress node for termination; and indicating the selected PTM flow in an upstream direction of the selected flow. | 02-24-2011 |
| 20110080854 | Method And System For Controlled Tree Management - There is disclosed a method and apparatus for facilitating a network, such as an Ethernet LAN, for efficient forwarding of data traffic by collecting neighbor information, generating and distributing link state advertisements, populating a topology database for the network, and calculating trees for each bridge serving as a root bridge. In a preferred embodiment the method and system also prepare one or more backup topologies, and store them for use if they are needed due to a failure condition detected in the network. In a particularly preferred embodiment, probabilities are assigned to various potential failure conditions, and the probability values are used to decide which backup topologies to calculate, store, or use. | 04-07-2011 |
| 20110116418 | Multiple Tree Registration Protocol - A registration protocol for setting up and updating a tree that defines the active topology in an Ethernet network includes a plurality of application components and a plurality of attribute declaration components corresponding to the application components, wherein the application components declare and register attribute values and the corresponding attribute declaration components make and withdraw registration of the attributes. | 05-19-2011 |
