Abstract – We have developed a refinement to existing methods to increase the capacity
efficiency of span-restorable mesh networks on sparse facility graphs. The new approach views the
network as a “meta-mesh of chain sub-networks.” This makes the prospect of WDM mesh
networking more economically viable than with previous mesh-based design where the average
nodal degree is low. The meta-mesh graph is a homeomorphism of the complete network in which
edges are either direct spans or chains of degree-2 nodes. The main advantage is that loop-back type
spare capacity is provided only for the working demands that originate or terminate in a chain, and
not for the entire flow that crosses a chain. The transiting (“express”) flows are entirely mesh-
protected within the meta-mesh graph which is of higher average degree and hence efficiency for
mesh restoration, than the network as a whole. Nodal equipment savings also arise from the
grooming of express lightpaths onto the logical chain-bypass span. Only the meta-mesh nodes need
optical cross-connect functionality. Other sites use OADMs and/or glassthroughs. The resultant
designs comprise a special class of restorable network that is intermediate between pure span
restoration and path restoration. Most of the efficiency of path restoration is achieved, but with a
span restoration mec
