ZTSFC: A Service Function Chaining-Enabled Zero Trust Architecture
IEEE Access, 2023 Recently, zero trust security has received notable attention in the security community. However, while many networks use monitoring and security functions like firewalls, their integration in the design of zero trust architectures remains largely ...

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 ...

VNF Availability and SFC Sizing Model for Service Provider Networks
IEEE Access, 2020 This paper considers service provider network design with a view of meeting application availability. Our primary goal is to design a service provider network using disparate network components and low-availability Virtual Network Functions (VNFs) while ...

HP-SFC: Hybrid Protection Mechanism Using Source Routing for Service Function Chaining
Applied Sciences, 2021 Service Function Chaining (SFC) is an emerging paradigm aiming to provide flexible service deployment, lifecycle management, and scaling in a micro-service architecture. SFC is defined as a logically connected list of ordered Service Functions (SFs) that

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.
