Logical path control system and logical path control method

摘要

PROBLEM TO BE SOLVED: To reduce the number of logical paths.SOLUTION: A logical path control system 1 includes: a plurality of optical line terminals (OLT) 40-1, ..., 40-X, a plurality of physical devices 50-1, ..., 50-Y, and a logical path management controller 10 for controlling logical paths L1a, ..., L4a between the plurality of optical line terminals 40-1, ..., 40-X and the plurality of virtual network functions (VNF) 51-1, ..., 5X-Y. The logical path management controller 10 determines, from the plurality of optical line terminals 40-1, ..., 40-X, optical line terminals 40-1, 40-2 that are to set logical paths L1a, ..., L2c with a plurality of virtual network functions 51-1, ..., 52-Y. The logical path management controller 10 sets the logical paths L1a, ..., L2c between the determined optical line terminals 40-1, 40-2 and the plurality of virtual network functions 51-1, ..., 52-Y.SELECTED DRAWING: Figure 1
