Resource Management Architecture of Metro Aggregation Network for IoT Traffic

Abstract

SUMMARY IoT (Internet of Things) services are emerging and the bandwidth requirements for rich media communication services are increasing exponentially. We propose a virtual edge architecture comprising computation resource management layers and path bandwidth management layers for easy addition and reallocation of new service node functions. These functions are performed by the Virtualized Network Function (VNF), which accommodates terminals covering a corresponding access node to realize fast VNF migration. To increase network size for IoT traffic, VNF migration is limited to the VNF that contains the active terminals, which leads to a 20 % reduction in the computation of VNF migration. Fast dynamic bandwidth allocation for dynamic bandwidth paths is realized by proposed Hierarchical Time Slot Allocation of Optical Layer 2 Switch Network, which attain the minimum calculation time of less than 1/100.

Highly efficient optical aggregation network with network functions virtualization

“…For cost‐efficient end‐to‐end cloud networking, minimum‐cost mapping must be found that efficiently aggregates traffic from numerous AGNs to datacenters, while reducing the consumption of physical link resources. In addition, metro/access networks account for most of the network cost . Thus, virtual network embedding problems in metro aggregation networks must be solved for cost‐efficient cloud networking.…”
