One Sentence Summary:
presents a network design optimization methodology to implement ultra reliable low latency communications (URLLC) in a metro area
Abstract:
-Optical aggregation network is a key subsystem to support high performance end-to-end services in 5G mobile networks. This paper presents a network design optimization methodology to implement ultra reliable low latency communications (URLLC) in a metro area. Novel optimization algorithms based on Integer Linear Programming (ILP) are defined to solve dedicated (DPP) and shared (SPP) path protection problems, in the presence of single failure with the aim to minimize the number of active nodes, by adopting the functional splitting options defined by 3GPP. The results prove the ability of the proposed algorithm to find optimal solutions which also minimize the number of high capacity node instances and the usage of bandwidth resources, especially when SPP is applied.
