Latency and policy aware hierarchical partitioning for NFV systems
Abstract
This paper explores latency-aware and policy-aware optimized placement of virtual network functions across data centers in NFV systems. A hierarchy of distributed data centers is suggested to support network function software appliances with the flexibility to place functions based on performance requirements in the hierarchy, and different test scenarios for optimal VNF placement are studied. The paper discusses options for distributed function virtualization such as hierarchical partitioning, collapsing, replication, and north/south function splitting, to explore VNF placement options in NFV systems.
