Abstract
Methods, devices, and systems for selecting a link of a link group based on contents of a concealed header are disclosed. A network node operating method includes a first network node receiving a packet and concluding that a link group connecting the first network node to a second network node will forward the packet to the second network node. The method further includes determining that the packet includes a tunnel header and an original header concealed by the tunnel header, selecting one link from among a set of parallel links of the link group based at least on one or more fields of the concealed original header, and forwarding the packet to the second network node via the selected link.
