Patent ID: 7961664

Claim:
A method for a digraph linked network to provide subnetwork communication comprising: running a first superframe in a digraph linked network containing a first digraph link, a second digraph link, and a third digraph link, wherein the first digraph link is a directional link specifying routing information between a first node and a second node in the digraph linked network, wherein the second digraph link comprises a directional link specifying routing information between the second node and a third node in the digraph linked network, wherein the third digraph link comprises a directional link specifying routing information between the third node and a fourth node in the digraph network, wherein a digraph of the digraph linked network forwards a packet using the first digraph link, the second digraph link, and the third digraph link towards a destination node; such that a packet forwarded along each digraph flows toward a destination node; and running a second superframe in the digraph linked network, wherein the second superframe includes defining communicating among a subset of nodes of the digraph linked network.
