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.

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.

Dynamic Fault Management in Service Function Chaining

2020 IEEE 44th Annual Computers, Software, and Applications Conference (COMPSAC), 2020
Service Function Chaining (SFC) is an important mechanism in Software-Defined Network/Network Function Virtualization (SDN/NFV) to allow the network traffic to be forwarded through a pre-defined ordered set of Virtual Network Functions (VNFs). Nevertheless, such a chain may be broken with the failure of a VNF. In this research, we propose a novel fault

Energy-Aware Service Function Placement for Service Function Chaining in Data Centers

2016 IEEE Global Communications Conference (GLOBECOM), 2016
Nowadays, data centers deploy a large number of servers and network devices to provide various service functions (e.g. firewalls, deep packet inspection, content caches, WAN optimizers, etc.) and sufficient network connection. Most traffic in data centers is subject to treatment by multiple service functions (SFs) which form an ordered service function

HybridSFC: Accelerating Service Function Chains with Parallelism

2019 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN), 2019
Network Function Virtualization (NFV) coupled with Software Defined Networking (SDN) creates new opportunities as well as substantial challenges such as increased Service Function Chain (SFC) latency and reduced throughput. In this paper, we present HybridSFC, a framework that explores the opportunities of parallel packet processing at both traffic ...

Service Function Chain Deployment with Guaranteed Resilience

2020 IEEE 17th International Conference on Mobile Ad Hoc and Sensor Systems (MASS), 2020
Network Function Virtualization (NFV) transforms the implementation of network functions from expensive hardwares to software middleboxes. These software middleboxes, also called Virtual Network Functions (VNFs), are executed on virtualization platforms, which makes them more prone to error compared to dedicated hardwares. One effective way of ensuring

A self-recovery scheme for service function chaining

2015 International Conference on Information and Communication Technology Convergence (ICTC), 2015
Service function chaining provides a new service deployment model that delivers the traffic along the predefined logical paths of service functions with no regard of network topologies or transport mechanisms. The traffic path of service functions needs to be recovered at failure of the service functions but it may incur a signaling delay among control-

On Dynamic Service Function Chain Deployment and Readjustment

IEEE Transactions on Network and Service Management, 2017
Network function virtualization (NFV) is a promising technology to decouple the network functions from dedicated hardware elements, leading to the significant cost reduction in network service provisioning. As more and more users are trying to access their services wherever and whenever, we expect the NFV-related service function chains (SFCs) to be ...
