Distributed service function failover mechanism in service function chaining

2017 International Conference on Information Networking (ICOIN), 2017
In service function chaining (SFC), end-to-end traffic flows are classified and processed by an ordered set of service functions (SFs). When SF in the chain fails, the corresponding traffic flows cannot be processed further to reach the destination until the failed SF recovers.

Optimal placement of service function in service function chaining

2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN), 2016
In service function chaining (SFC), an ordered list of service functions (SFs) is specified for network services, and those SFs should be placed in appropriate service nodes (SNs) to satisfy the given service latency requirement. In this paper, we formulate an integer non-linear programming (INLP) problem for the optimal placement of SFs when the ...

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).

Fault Tolerant Service Function Chaining

Proceedings of the Annual conference of the ACM Special Interest Group on Data Communication on the applications, technologies, architectures, and protocols for computer communication, 2020
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. Making a chain fault-tolerant is challenging since, in the event of failures, the state of faulty middleboxes ...

On Achieving Trustworthy Service Function Chaining

IEEE Transactions on Network and Service Management, 2021
Service Function Chaining (SFC) has recently received considerable attentions from both industry and academia, due to its potential for improving the flexibility of provisioning and composition of Virtualized Network Functions (VNFs) to suit application-specific needs.

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-

Network function consolidation in service function chaining orchestration

2016 IEEE International Conference on Communications (ICC), 2016
Network Function Virtualization (NFV) is an emerging technology proposed to improve service provisioning in telecommunication industry. The flexibility of NFV enables network operator to dynamically deploy Virtual Network Functions (VNFs) according to real-time requirements.
