TLDR
This chapter defines Network Functions Virtualization, including examination of the ETSI model for NFV, as well as NFV Orchestration and Infrastructure, and considers what functionality can actually be virtualized, including provider edge routers, firewalls, deep packet inspection, and intrusion prevention.Abstract:
In this chapter we define Network Functions Virtualization, including examination of the ETSI model for NFV, as well as NFV Orchestration and Infrastructure. We consider what functionality can actually be virtualized, including provider edge routers, firewalls, deep packet inspection, and intrusion prevention. We introduce the reader to an open source platform for NFV called OPNFV. We list the major vendors involved in NFV, including their products as well as their target domains. Lastly we look at the relationship between SDN and NFV, describing how SDN can be used to enable and even enhance NFV.read more

New Paradigm of 5G Wireless Internet
TL;DR: An overview of China Mobile's 5G vision and potential solutions is provided, Targeting a paradigm shift to user-centric network operation from the traditional cell-centric operation, 5G radio access network (RAN) design considerations are presented, including RAN restructure, Turbo charged edge, core network and RAN function repartition, and network slice as a service.

Virtual function placement and traffic steering in flexible and dynamic software defined networks
TL;DR: This paper forms the problem of network function placement and routing as a mixed integer linear programming problem, and develops heuristics to solve the problem incrementally, allowing it to support a large number of flows and to solving the problem for incoming flows without impacting existing flows.

Optimizing Virtual Backup Allocation for Middleboxes
TL;DR: This work suggests a novel approach for planning and deploying backup schemes for network functions that guarantee high levels of survivability with significant reduction in resource consumption and describes different goals that network designers can take into account when determining which functions to implement in each of the backup servers.

TL;DR: This work introduces ClickOS, a high-performance, virtualized software middlebox platform, and implements a wide range of middleboxes including a firewall, a carrier-grade NAT and a load balancer and shows that ClickOS can handle packets in the millions per second.

Deep Packet Inspection as a Service
TL;DR: This paper proposes to treat DPI as a service to the middleboxes, implying that traffic should be scanned only once, but against the data of all middleboxes that use the service, having significant advantages in performance, scalability, robustness, and as a catalyst for innovation in the middlebox domain.
