Abstract
In the operation of an MPLS network or the like, a network node receives a plurality of packets assigned to a label switched path (LSP) which exits the node on a link bundle. The node forwards the received packets such that packets assigned to the LSP are distributed over two or more distinct component links of the bundle.
Claims10
A method, comprising:
- receiving, at a network node, a plurality of packets assigned to a label switched path (LSP) which exits the node on a link bundle;
- forwarding the received packets such that packets assigned to the LSP are distributed over two or more distinct component links of the bundle, wherein the forwarding is carried out by a routing device, and during the forwarding, all packets belonging to the same flow traverse the same internal path within the routing device;
- and
- computing, for each packet, a number that is the same for packets that belong to the same flow, but different for packets that belong to different flows, and wherein the forwarding is carried out such that packets are distributed over the component links according to the respective values of said computed number.

- receiving, at a network node, a plurality of packets assigned to a label switched path (LSP) which exits the node on a link bundle;
- and
- forwarding the received packets such that packets assigned to the LSP are distributed over two or more distinct component links of the bundle, wherein the forwarding is carried out by a routing device having a first, a second, and a third stage, and during the forwarding, the first stage forwards packets to the second stage, the second stage forwards packets to the third stage, and the third stage forwards packets onto component links.
