A method and apparatus for reserving bandwidth in a network includes a series of elements (1B). A demand matrix is calculated (6), for bandwidth requirements based upon communication needs among a plurality of nodes on the network (2). An integer number of time slots is provided (4) aligned around the network. Bandwidth is reserved for node-to-node communication based upon the demand matrix (8). The reserving of bandwidth reserves bandwidth between two nodes based upon time-slot alignment (14). Transmission is scheduled between the two nodes by reservation of wavelengths and time slots (15). |
