Technique for bundling in link aggregation

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.

1. A method for configuring a plurality of first Link Aggregation Group (LAG) nodes of a first LAG virtual node of a first network, the method implemented by a Network Management System (NMS) computing device and comprising:
creating service-to-bundle assignments that assign each of a plurality of network services that utilize the first LAG nodes to a respective LAG bundle, wherein each LAG bundle designates one or more first links between the first LAG virtual node and a second LAG virtual node of a remote second network as active links, and designates one or more other links between the first and second LAG virtual nodes as standby links to be used in case of active link failure; and transmitting the service-to-bundle assignments to the first LAG nodes, wherein the first LAG nodes are included in a plurality of LAG bundles.
