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 ...

Robust service provisioning of service function chain under demand uncertainty
IET Communications, 2022 In network function virtualization, resource allocation is one of the key techniques to ensure the QoS of service requests in face of the uncertain traffic demand and traffic fluctuation of user services.

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 ...

A survey on service function chaining
Journal of Network and Computer Applications, 2016 Cloud computing is gaining significant attention and virtualized datacenters are becoming popular as a cost-effective infrastructure. The network services are transitioning from a host-centric to a data-centric model moving the data and the computational resources closer to the end users.

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.

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 ...
