摘要： Methods and apparatus for operating a virtual node in a LAG that includes a first virtual node and a second virtual node are disclosed. The first virtual node includes at least a first fellow node and a second fellow node. In one exemplary method, the first fellow node receives, from the second virtual node, first control information comprising a system ID and first configuration information associated with the LAG. The first control information is compared with reference configuration information representing previously established expected configuration information associated with the LAG. Based on that comparison, and at least one additional criterion, a split brain condition may be determined to exist in the LAG. In a complementary fashion, a fellow node of the second virtual node may be configured to alter its transmitted configuration information depending on whether it is able to communicate with its fellow node in the second virtual node.

摘要： A technique for determining an interconnect node for establishment of a forwarding path for transmitting service based data within a network system comprising a first network and a second network is provided. The first network comprises: a plurality of network interconnect nodes connectable to a plurality of external links towards the second network, and one or more internal links connecting the network interconnect nodes with each other. A method implementation of the technique comprises assigning, for a given service, interconnect node status information to the network interconnect nodes, wherein a network interconnect node to which a passive status is assigned is only allowed to transmit service based data between an external link and another interconnect node of the network, or between two other interconnect nodes of the network, and wherein only a network interconnect node to which an active status is assigned is allowed to send or receive service based data to or from the network. The method further comprises determining, for a given service, an interconnect node having an active status for establishment of a forwarding path including the interconnect node having the active status and an external link, wherein the determination is based on the respective status information assigned to the network interconnect nodes for the service.

摘要： A technique for status change handling in an interconnect node is described, wherein the node comprises a data plane that can assume, per service, a passive or active status. A method aspect in the node comprises transmitting, to another node, a first indication that a change has been or is about to be performed, awaiting, from the other node, reception of a second indication that the data plane in the other node has been set to the passive status, and activating, responsive to the received indication, the data plane of the node from the passive status to the active status. The method aspect in the other node further comprises receiving, from the node, the first indication, passivating, responsive to the receiving step, the data plane being in the active status to the passive status, and transmitting, upon completion of the passivating step, the second indication.

摘要： The present disclosure provides a technique for ensuring that a service or conversation is carried in a congruent manner on a Link Aggregation Group (LAG). The Service ID (e.g., conversation ID) to link mapping is configured on both sides of the LAG independently of each other. The Service ID to link assignment is stored in a well-defined format, e.g. in an assignment table. A digest is then prepared on the assignment table. The digest is exchanged between the two sides of the LAG. If there is a mismatch between the digests, then the service is transmitted on a predefined and agreed-upon default link if congruency has to be enforced for that particular service. Furthermore, the digest exchange allows verification on the configuration to check whether all services to be handed-off are configured on both sides.

摘要： A system and method for in-service migration for a Virtual Local Area Network, VLAN, service if a Provider Bridge Metro Ethernet Network, PB MEN, is upgraded to a Provider Backbone Bridge, PBB, MEN or an Internet Protocol/Multi Protocol Label Switching, IP/MPLS, MEN. After the deployment of the new PBB or IP/MPLS technology, a sequence of management actions are performed to configure PBB or IP/MPLS edge nodes to use the new technology as well as the old PB-based technology to support the VLAN service. Both old and new connectivity structures are maintained in the edge nodes during the entire migration process. Customer traffic is then redirected per edge node to the new technology. When each edge node entirely provides the VLAN service under the new technology, the migration is complete.

摘要： Methods and apparatus are disclosed for applying multiple Link Aggregation Group (LAG) entities on the same set of physical links, thus making bundling of individual services or conversations possible by the different LAG entities within Link Aggregation. Each LAG entity is configured such that a single physical link is Active and all the other links are Standby. Each LAG entity may be regarded as a "bundle." Thus the services/conversations are bundled into a LAG entity and are handed-off on the Active link during normal operation. If service hand-off is not possible on the Active link (e.g., due to a failure), then the LAG entity switches over to a Standby link thus the service/conversation is handed-off on that formerly Standby link. Bundling may simplify operations of control and signaling.

摘要： A flow classification process is used at the edge of the shortest path bridging network to determine a flow label (320) for attachment to a client frame (330) entering the network. Any of several flow labels (320) can be assigned to a client frame (330) traversing the network to a particular egress node, and the flow labels are used by forwarding nodes to select among multiple equal -cost paths. In several embodiments, the flow label is calculated as a function of the client frame contents, which provide an entropy source for randomizing the selection of the flow label. This entropy source comprises the Internet Protocol (IP) header in the client frame, in some embodiments, but may comprise other client frame content in other cases.
