Cost-efficient virtual network function chaining over NFV-based telecommunications networks
2017 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS), 2017Network Function Visualization (NFV) enables the softwarization of network functions on standardized commodity hardware, which is promising to help the network carriers to achieve a lower investment cost, a shorter time to deployment, as well as a more flexible and dynamic way of network configuration and management. One of the key challenges is how to

It is essential for economical NFV-based network design to determine the place where each network function should be located in the network and what its capacity should be. The authors proposed an algorithm of virtual routing function allocation in the NFV-based network for minimizing the network cost, and provided effective allocation guidelines for ...

The certificate cost and certificate management complexity increase when PKI is leveraged into Network Function Virtualization (NFV), a significant enabling technology for 5G networks. The expected security of PKI cannot be met because the certificate revocation inquiry is unavailable during the intranet implementation in the operator’s core network ...

Network Functions Virtualization (NFV) for mobile networks
The target of Network Function Virtualization (NFV) is to decouple network hardware and software, enable the development of network solutions by using multi-vendor hardware that can effectively cooperate with multi-vendor software platforms and replace current standard networking operations for fixed and mobile networks. It is hoped that CAPEX and OPEXopenaire +1 more source

Abstract Network function virtualization (NFV) and edge computing (EC) are two promising and innovative technologies to accelerate 5G networks. However, placing the service function chains (SFC), each of which consists of a series of ordered virtual network functions (VNFs), into the EC enabled networks is an intractable issue and some new challenges

We propose SLA-NFV, a Service Level Agreement (SLA) aware framework, for building high-performance NFV, focusing on fulfilling SLAs of service subscribers (or tenants). SLA-NFV leverages a hybrid infrastructure with both software and programmable hardware to enhance NFV’s capability with respect to various SLAs.
