Abstract:
1. A lattice network comprising: a plurality of optical shell nodes logically arranged in at least two primary networks, each said primary network having at least two optical shell nodes interconnected by where said optical shell nodes are further logically arranged in at least two secondary networks, each said secondary network having an interconnection means for interconnecting selected optical shell nodes, said selected optical shell nodes including one of said at least two optical shell nodes from each of said at least two primary networks; a plurality of shell controllers, each shell controller associated with an optical shell node; and a plurality of edge nodes, each edge node subtending to at least one of said plurality of optical shell nodes, said each edge node having an edge controller exchanging time-locking signals with a shell controller of each of said at least one of said plurality of optical shell nodes wherein each of said at least one primary optical core node comprises parallel switch planes and each of said at least two optical shell nodes connects to each switch plane of said parallel switch planes.
