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.

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 ...

Coordinated Allocation of Service Function Chains

2015 IEEE Global Communications Conference (GLOBECOM), 2014
Network Functions Virtualization (NFV) is an emerging initiative to overcome increasing operational and capital costs faced by network operators due to the need to physically locate network functions in specific hardware appliances. In NFV, standard IT virtualization evolves to consolidate network functions onto high volume servers, switches and ...

Resilient allocation of service Function chains

2016 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN), 2016
Network Functions Virtualization (NFV) is an emerging initiative where standard IT virtualization evolves to consolidate network functions onto high volume servers, switches and storage that can be located anywhere in the network. One of the main challenges to implement NFV is the problem of allocating Virtual Network Functions (VNFs) on top of the ...

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-

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

Breaking Service Function Chains with Khaleesi

2018 IFIP Networking Conference (IFIP Networking) and Workshops, 2018
Network Function Virtualization (NFV) has recently emerged as a means to replace vendor specific, purpose built equipment with commodity hardware and leverage the open APIs and application orchestration for on demand deployment and scaling of network services.

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.

Joint Optimization of Service Function Placement and Flow Distribution for Service Function Chaining

IEEE Journal on Selected Areas in Communications, 2017
In this paper, we consider the problem of optimal dynamic service function (SF) placement and flow routing in a SF chaining (SFC) enabled network. We formulate a multi-objective optimization problem to maximize the acceptable flow rate and to minimize the energy cost for multiple service chains.

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.
