Patent ID: 7684389

Claim:
A lattice network comprising: a plurality of edge modules arranged into: a group of non-intersecting primary sub-nets, each primary subnet having a first number of edge modules; a group of non-intersecting secondary sub-nets, each secondary sub-net having a second number of edge modules; and a group of non-intersecting ternary sub-nets, each ternary-subnet having a third number of edge modules; and a plurality of core modules arranged into: a group of primary core stages, each primary core stage exclusively assigned to a respective primary sub-net and having a number of primary core modules, each said primary core module connecting to each edge module of said respective primary sub-net; a group of secondary core stages, each secondary core stage exclusively assigned to a respective secondary sub-net and having a number of secondary core modules, each said secondary core module connecting to each edge module of said respective secondary sub-net; and a group of ternary core stages, each ternary core stage exclusively assigned to a respective ternary sub-net and having a number of ternary core modules, each said ternary core module connecting to each edge module of said respective ternary sub-net; wherein each edge module belongs to only one of said primary sub-nets, only one of said secondary sub-nets, and only one of said ternary sub-nets.
