摘要： A method and ingress node for configuring intermediate OAM monitoring entities to monitor the quality of segments of a communication connection between an ingress node and an egress node. The ingress node constructs an object that includes technology-independent OAM parameters, identities of the OAM monitoring entities to be configured, and technology- specific attributes, wherein the technology-independent OAM parameters define an OAM type and desired monitoring actions by each of the identified OAM monitoring entities, and the technology-specific attributes define descriptors for configuring the 0AM monitoring entities in accordance with a communication protocol utilized for the connection. The ingress node utilizes Generalized Mu Its- Protocol Label Switching, GMPLS, signaling to send the object to the OAM monitoring entities. The object may be a Hop Attributes sub-object or a Label Switching Protocol, LSP, Attributes object including a Segment OAM Configuration Type-Length-Value, TLV, field that includes the technology-independent OAM parameters and technology- specific attributes.

摘要： Extensions to a Multi-Protocol Label Switching (MPLS) frame forwarding procedure in an MPLS node are described. A context descriptor is defined for each frame received on a connection terminated at that node, and where this context descriptor is provided together with the frame to a corresponding function (e.g. Operations, Administration and Maintenance, OAM) if needed. The context descriptor is constructed based on key attributes characterizing the terminated connection, over which the frame is received, and addresses a particular function endpoint (Maintenance Endpoints (MEPs), Selector Bridge of a protection instance etc.) of a corresponding function (OAM, protection, etc.). In one embodiment, a Multi-Protocol Label Switching (MPLS) node is directed to check not only the first but also the second label, and not to drop the first label (and the label space if relevant) when the second label is the Generic Association Channel Label (GAL). In this way, the original context of the packet is kept (i.e. the information relating to the connection over which the packet was received), and can be used for de-multiplexing to the corresponding MEP. Then the identifiers within the OAM payload can be used for verification of the connectivity. Other embodiments describe alternative solutions.
摘要翻译：描述MPLS节点中多协议标签交换（MPLS）帧转发过程的扩展。为在该节点处终止的连接上接收的每个帧定义上下文描述符，并且如果需要，该上下文描述符与帧一起被提供给相应的功能（例如，操作，管理和维护，OAM）。上下文描述符是基于表征终止的连接的关键属性构成的，通过该关键属性接收帧，并且寻址相应功能（OAM，等等）的特定功能端点（维护端点（MEP），保护实例的选择器桥等）保护等）。在一个实施例中，多协议标签交换（MPLS）节点被指示用于不仅检查第一标签，而且还检查第二标签，并且当第二标签是通用标签时，不删除第一标签（以及相关的标签空间）关联通道标签（GAL）。以这种方式，保持分组的原始上下文（即，与接收到分组的连接有关的信息），并且可以用于对相应的MEP进行解复用。那么OAM有效载荷内的标识符可以用于连接的验证。其他实施例描述了替代解决方案。

摘要： The present invention relates to an ingress node (102, 700) and methods therein for Operation Administration arid Maintenance, OAM related to Resource Reservation Protocol- Traffic Engineering, RSVP-TE5 for obtaining attributes for timer values being assigned to a connection from the ingress node (102) via intermediate nodes (104, 106, 108, 110) to an egress node (112), during configuration of die connection. An interval of suitable tinier values for the intermediate nodes is specified. Configuration attributes are obtained for a timer value within an interval that is acceptable by the intermediate nodes and the egress node, based on the specified interval of suitable timer values. The obtained configuration attributes are applied during configuration of the connection from the ingress node via the intermediate nodes to the egress node, if the obtained configuration attributes are appropriate to the ingress node. Fine-tuning of connection related timers can therefore be achieved, decreasing the overall recovery time and the overall overhead.

摘要： A method performed by a network element, for notifying a controller of a change to a packet forwarding configuration of the network element. The network element is separated from the controller by a communication channel. The method includes determining the change to the packet forwarding configuration of the network element. The packet forwarding configuration specifies how packets are to be forwarded by the network element. The method also includes actively notifying the controller of the change to the packet forwarding configuration by sending a message to the controller over the communication channel. The message, in addition to indicating the change, also indicates at least one detail about the packet forwarding configuration after the change.

摘要： A method to facilitate the broadcast of frames between a set of Edge Nodes of a transport network, where nodes of the transport network forward frames using labels added to the frames at ingress Edge Nodes. The method comprises, at each of said Edge nodes a nd at intermediate nodes in the paths between said Edge Nodes, installing an entry or entries into a forwarding table mapping frame labels to output forwarding ports such that said entries together form a single forwarding construct such that frames labell ed by any of the Edge Nodes of said set are transmitted to all other Edge Nodes of the same set. Upon receipt of a frame at one of said Edge Nodes or intermediate nodes, the provided forwarding table is used to map the frame label of the frame to one or m ore forwarding ports. Frames are then sent via the identified forwarding port(s).
