Service Function Chain Migration: A Survey

Computers
As a core technology emerging from the convergence of Network Function Virtualization (NFV) and Software-Defined Networking (SDN), Service Function Chaining (SFC) enables the dynamic orchestration of Virtual Network Functions (VNFs) to support diverse ...

Traffic Steering for Service Function Chaining [PDF]

IEEE Communications Surveys & Tutorials, 2019
Dynamic service function chaining (SFC) is a technique that facilitates the enforcement of advanced services and differentiated traffic forwarding policies. It dynamically steers the traffic through an ordered list of service functions. Enabling SFC capabilities in the context of a software defined networking (SDN) architecture is promising, as it ...

A Scalable Algorithm for the Placement of Service Function Chains [PDF]

IEEE Transactions on Network and Service Management, 2016
Network function virtualization (NFV) decouples software implementations of network functions from their hosts (or hardware). NFV exposes a new set of entities, the virtualized network functions (VNFs). The VNFs can be chained with other VNFs and physical network functions to realize network services.

Composing and deploying parallelized service function chains

Journal of Network and Computer Applications, 2020
Abstract Network Function Virtualization (NFV) provides great flexibility in solving the problem of deploying service function chains (SFCs). The existing serial SFCs organize virtual network functions (VNFs) in a predefined order and execute the VNFs one by one, which can result in high SFC delay as the lengths of the SFCs increases.

Distributed Service Function Chaining [PDF]

IEEE Journal on Selected Areas in Communications, 2017
A service-function chain, or simply a chain, is an ordered sequence of service functions, e.g., firewalls and load balancers, composing a service. A chain deployment involves selecting and instantiating a number of virtual network functions (VNFs), i.e., softwarized service functions, placing VNF instances, and routing traffic through them.

SFCaaS: Service function chains as a service in NFV environments

ITU Journal on Future and Evolving Technologies, 2022
With the growing deployment of emergent technologies like software-defined networking, network services are expected to be revolutionized. In this paper, we investigate offering Service Function Chains as a Service (SFCaaS) in NFV environments. We describe the potential business model to offer such a service and then we address the service function ...

Prioritized Deployment of Dynamic Service Function Chains [PDF]

IEEE/ACM Transactions on Networking, 2021
Service Function Chaining and Network Function Virtualization are enabling technologies that provide dynamic network services with diverse QoS requirements. Regarding the limited infrastructure resources, service providers need to prioritize service requests and even reject some of low-priority requests to satisfy the requirements of high-priority ...

Service Function Chaining Simplified

CoRR, 2016
Middleboxes have become a vital part of modern networks by providing service functions such as content filtering, load balancing and optimization of network traffic. An ordered sequence of middleboxes composing a logical service is called service chain. Service Function Chaining (SFC) enables us to define these service chains.
