TUNNEL PROVISIONING WITH LINK AGGREGATION

摘要

A method for processing data packets in a communication network includes establishing a path for a flow of the data packets through the communication network. At a node along the path having a plurality of aggregated ports, a port is selected from among the plurality to serve as part of the path. A label is chosen responsively to the selected port. The label is attached to the data packets in the flow at a point on the path upstream from the node. Upon receiving the data packets at the node, the data packets are switched through the selected port responsively to the label.

1. A method for assigning and utilizing an Ethernet physical data port in an Ethernet Link Aggregation Group (LAG) in a Multi-Protocol Label Switching (MPLS) network, the method comprising the steps of:
selecting, by a first MPLS/LAG switch, from a plurality of physical data ports in said first MPLS/LAG switch, a single physical tunnel port of the LAG which meets a bandwidth requirement of a network tunnel, wherein said single physical tunnel port has a port serial number; assigning, by said first MPLS/LAG switch, said single physical tunnel port to said network tunnel; preparing, by said first MPLS/LAG switch, a data packet label by which said single physical tunnel port may be identified; sending, by said first MPLS/LAG switch, a message comprising said data packet label to a preceding node; receiving from the preceding node, by said first MPLS/LAG switch, a data packet comprising said data packet label; and switching, by said first MPLS/LAG switch, said data packet to said single physical tunnel port according to said serial port number, and sending said data packet to a second MSPLS/LAG switch via said single physical tunnel port.
