The fast growing development of Network Function Virtualization (NFV) trends and the remarkable progress of Software Defined Networking (SDN) have yielded a synergy between both, towards the provision of convergent networking solutions. Since the traditional networking principles were not designed according to the NFV principles, a work has emerged dedicated to protocol redesign among the academic...
This paper describes the experimentation on the Future Internet Research & Experimentation (FIRE) Long Term Evolution (LTE) testbeds for open experimentation (FLEX) facilities by combining the existing Evolved Node B (eNB) with an execution infrastructure. In this direction, LTE Edge Network Enhancement with Core Functionalities (LENA) project will enhance the LTE FLEX testbed with a Network Function...
The surge of the Internet traffic with exabytes of data flowing over operators' mobile networks has created the need to rethink the paradigms behind the design of the mobile network architecture. The inadequacy of the 4G UMTS Long term Evolution (LTE) and even of its advanced version LTE-A is evident, considering that the traffic will be extremely heterogeneous in the near future and ranging from...
The paper leverages the emerging paradigm of Network Function Virtualization (NFV) in an attempt to outline from the network management point of view the current trends on the road to 5G region. To that end, relevant architectural frameworks and concepts have been presented and the anticipated network densification through the notion of Edge Cloud has been discussed.Within this context, added value...
