A Multi-Stage Graph Aided Algorithm for Distributed Service Function Chain Provisioning Across Multiple Domains

IEEE Access, 2021
Network Service Providers (NSPs) envisage to support the divergent and stringent requirements of future services by instantiating these services as service chains, commonly referred to as Service Function Chains (SFCs), that are customized and configured

Fault Tolerance for Service Function Chains

CoRR, 2020
Enterprise network traffic typically traverses a sequence of middleboxes forming a service function chain, or simply a chain. Tolerating failures when they occur along chains is imperative to the availability and reliability of enterprise applications.

Service Function Chaining Architecture for Multi-Hop Split Inference

IEEE Transactions on Machine Learning in Communications and Networking
Service Function Chaining (SFC) ensures traffic follows a predefined sequence of service functions, enabling dynamic and efficient network services. Inspired by this, we propose an SFC-based architecture for Multi-hop Split Inference (MSI), where split ...

Optimal Construction of Service Function Chains Based on Security Level for Improving Network Security

IEEE Access, 2019
In this paper, in order to improve network security, we propose an optimal placement of security virtual network function (security VNF) for service function chains based on the security level.

Evaluation of Reactive Service Function Path Discovery in Symmetrical Environment

Telfor Journal, 2022
In this paper we continue our study of path discovery process for Service Function Chaining (SFC) in Software Defined Network (SDN). By default, service function (SF) paths are established proactively - before data transmission takes place.

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.
