Service failure diagnosis in service function chain

2017 19th Asia-Pacific Network Operations and Management Symposium (APNOMS), 2017
Network function virtualization (NFV) is a powerful emerging technique with widespread applicability. It provides Network Functions (NFs) through software virtualization techniques that decouple software and hardware. Some connected network functions constitute a service function chain (SFC).

Partially Symmetric Service Function Chains

2019 2nd IEEE Middle East and North Africa COMMunications Conference (MENACOMM), 2019
With the variety of proposed networking services and the growing requirements of subscribers, networking infrastructures strive to offer the best quality of service. Complex services, such as security services require a composition of intermediate Service Functions (SFs). Service Function Chaining (SFC) is a new trending networking concept that enables

Subscriber aware dynamic service function chaining

Computer Networks, 2021
Abstract In this study, a novel subscriber aware dynamic service function chaining (SFC) framework is developed by using open source software-defined networking (SDN) and network function virtualization (NFV) solutions, where the aim is to provide service chaining per user traffic and to transform SGi-LAN services into virtual network functions.

Order dependency-aware service function placement in service function chaining

2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017
In distributed network function virtualization (NFV) environments, the latency can be significantly increased as the length of service function chain (SFC) increases. To reduce the latency, the order dependency allowing parallel processing of service functions (SFs) can be exploited.

Bounding Reliability in Service Function Chaining

2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO), 2020
In Network Function Virtualization (NFV), the re-liability of Service Function Chain (SFC) is one of the most critical performance parameters. Since each SFC has different composition, placement, configuration and deployment requirements, the exact analysis of SFC reliability is a challenge. In this paper, we address this challenge by analyzing the end-
