ABSTRACT:
Techniques for making a recursive mesh network for connecting a varying number of access stations within a service area is disclosed. The techniques include (a) dividing the service area into M.times.N rectangular regions, having (M+1).times.(N+1) corners, which cover the entire range of the service area; (b) placing an access station at an available region corner whenever a new access station becomes available, and connecting the access station to its corresponding optical connection paths, until (M+1).times.(N+1) access stations have been so connected; (c) determining, for each additional new access station, which region the additional new access station falls within; (d) if this determined region has not been divided, dividing the determined region into S.times.T sub-regions; (e) if the divided determined region has less than (S+1).times.(T+1) access stations within it, placing the additional new access station at an available sub-region corner in the region and connecting the new additional access station to at least one other access station within the same region; and (f) if the divided determined region has (S+1).times.(T+1) access stations within it, repeating steps (c)-(f) with respect to that sub-region until the new additional access station can be connected. Also disclosed are an optical telecommunications network and techniques for routing information in a recursive mesh network.
