SDN/NFV based caching solution for future mobile network (5G)

Abstract

Caching content locally at the edge of the network and managing these caches by SDN/NFV based technologies are able to satisfy increasing data traffic demand in 5G. The virtualization of caching functionalities allows network operators to deploy caching services with advanced features like flexibility, dynamicity and auto-scalability, and provide caching services to service providers or virtualized network operators over the same common infrastructure. The caching management system provides two levels of operations: i) at the global level managed by the Infrastructure Provider applying to all the tenants or virtualized network operators; or ii) at the tenant-specific level managed by the specific tenants. Our caching solution opens an entirely new space of business opportunities for network operators, service providers and content providers.
