摘要： Aspects of the present disclosure relate 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.

摘要： 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.
摘要翻译：用于城域光网络的保护方案涉及使用主要组播标签交换路径（LSP）和备用LSP对入口节点和出口节点进行编程，以提供一对一保护。在发生网络故障之前配置主备份LSP和备份LSP，以允许网络在故障发生时传输组播通信。特别地，在正常操作期间，在主LSP上发送组播通信。但是，当发生网络故障时，节点也通过备份LSP发送重复的组播通信。在发生故障之前配置主备份和备份LSP避免了在发生故障后建立LSP的信令。

摘要： A connection-oriented network (5) has a plurality of connections terminated at a first node (N6). A recovery group (A) is configured at the first node (N6) comprising at least two of the plurality of connections (LSP1-6, LSP2-6, LSP3-6, LSP4-6). Fault detection is performed over each of the connections in the recovery group (A) and the node determines if at least one recovery group fault condition is met, based on the results of the fault detections performed over the connections in the recovery-group (A). When the at least one recovery group fault condition is met, the node causes traffic on the plurality of connections in the recovery group (A) to be transferred to backup paths. When the at least one recovery group fault condition is not met, and a fault has been detected on a connection in the recovery group (A), the node causes traffic to be transferred from that connection to a backup path.

摘要： Network interconnection apparatus comprising a platform with interface ports for network interconnection and comprising in turn a first series and a second series of interface port cards and an interconnection unit for commanded interconnection at least between the cards of the first and second series and between cards of the first series. The cards of the first series have their own associated MAC address tables for addressing traffic between ports through the interconnection unit. Each entry of the table has an age field defining in time the age of the entry. The content of the age field is periodically verified and if it reaches a preset maximum figure the entry is updated on the basis of the content of the age field by a corresponding entry in the table of another card of the first series and associated therewith by the information in the entry to be updated. If the content of the age field of the corresponding entry is also a maximum figure, both the entries can be deleted.

摘要： An apparatus and a method are described in which a flow of packets is distributed in several separate flows over several links (12) forming a logically aggregated link (11). The flow outgoing from each physical link is sent to its own policer (18) which applies to said flow a traffic policing algorithm with the policers being interconnected to exchange algorithm control parameter modification information to fit them in among the various policers while allowing for the control parameters of the others so that a distributed policer (15) is realized.

摘要： A node (110) for an MPLS telecommunications network has interfaces (100) for OAM information exchange relating to a path for data traffic, between first and second other nodes each operating according to different OAM state machines for OAM information exchange. An OAM state machine mapper (120) maps the states of either of the different OAM state machines of the first and second other nodes into states recognized by the other of the different OAM state machines. OAM information exchange is according to either the first or the second OAM state machine and according to states mapped from the other of the OAM state machines, to support the path for data traffic through the node. By such mapping of the different states OAM information can be exchanged across corresponding boundaries and so paths no longer need to be terminated at the boundary to enable end to end operations.
