ABSTRACT:
Techniques are described for distribution of label switched packets, such as multiprotocol label switched (MPLS) packets, across multiple physical data paths. The techniques may, for example, be used to load balance the label switched packets across an aggregated link having two or more logically associated physical interconnects. A network device, for example, includes an interface card to receive packets associated with a common label switched path (LSP), and a control unit to distribute the packets across multiple paths. The network device may include label data that maps ranges of labels, such as MPLS labels, to types of payloads carried by the label switched packets. In accordance with the label data, the control unit extracts flow information from the label switched packets and distributes the label switched packets across the paths based on the flow information. The control unit may generate hash values from the flow information, the labels, or combinations thereof, to control distribution of the label switched packets.
