20090003192 | Protection Mechanisms for a Communications Network - A method of path protection for a connection-oriented packet switched communications network is described using a protection hub in communication with a worker hub via a core protection path. Both the worker hub and the protection hub communicate with at least one provider edge device via a respective worker and protection paths. The method detects a failure in the communications network, indicates the failure to the at least one of the provider edge device, the worker hub, and the protection hub. The method then employs the core protection path if a failure occurs along a worker path is detected, or a worker path and a protection path in parallel if a failure occurs along the core protection path. | 01-01-2009 |
20090010154 | Protection Scheme - A protection scheme for a metro optical network involves programming ingress nodes and egress nodes with a primary multicast label switched path (LSP) and a back-up LSP to provide one-to-one protection. The primary and back-up LSPs are configured prior to the occurrence of a network fault to allow the network to transmit multicast communication when the fault occurs. Particularly, multicast communications are sent on the primary LSP during normal operation. However, when a network fault occurs, the nodes also send a duplicate multicast communication over the back-up LSP. Configuring the primary and back-up LSPs prior to the fault occurring avoids the need for signalling to establish a working LSP after a fault occurs. | 01-08-2009 |

20120287818 | MULTIPOINT-TO-MULTIPOINT SERVICE FOR A COMMUNICATIONS NETWORK - A multipoint-to-multipoint service is provided between a set of edge nodes of a communications network. The network comprises at least two sub-networks and an intermediate node at a boundary between sub-networks. For each pair of edge nodes comprising an edge node in a first of the sub-networks and an edge node in a second of the sub-networks, a multi-segment pseudowire connection is configured between the pair of edge nodes. The pseudowire connection passing via at least one intermediate node. At the intermediate node forwarding data is configured which specifies a forwarding relationship between pseudowire segments corresponding to the multi-segment pseudowire connections. A topology of Label Switched Paths carry the multi-segment pseudowires. Edge nodes within a sub-network can be connected with a mesh topology or a hub-and-spoke topology. | 11-15-2012 |
20130021918 | FAULT MONITORING IN CONNECTION-ORIENTED NETWORKS - The invention relates to a method of fault monitoring in a fault monitoring entity of a network node of a network having at least a first connection-oriented network layer, having first protection measures associated therewith, and a second connection-oriented network layer, having second protection measures associated therewith. In a first step the service condition status of the first network layer is monitored using the first protection measures. In a second step the second network layer protection measures are determined for onward transmission within the second network layer depending on the service condition status of the first network layer. Since the network node is aware of the monitored status condition of both the first and second layers the protection mechanisms for the first network layer and the second network layer can be co-ordinated and the second network layer protection measure for onward transmission may be determined for optimum network fault protection operation. | 01-24-2013 |
20140043976 | METHOD AND DEVICE FOR CREATING AND FOR RECEIVING A DATA PACKET WITH DISCARD ELIGIBLE INFORMATION - Aspects of the present disclosure relates to a method and a device for creating a data packet with discard eligible information and to a method and device for receiving a data packet with discard eligible information. Specifically, one aspect of the present disclosure provides a method for creating a data packet, containing a data payload and at least one label determining onward routing for the data packet, for onward transmission in a data communication system, a machine readable medium for implementing the method, and a corresponding device. In a first step a discard eligibility associated with the data packet is determined. In a second step, discard eligible information is encoded in a label determining onward routing for the data packet. In a third step an outgoing data packet including the label is generated. | 02-13-2014 |
