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-

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 ...

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.

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

Availability-aware mapping of service function chains

IEEE INFOCOM 2017 - IEEE Conference on Computer Communications, 2017
Network Function Virtualization (NFV) is a promising technique to greatly improve the effectiveness and flexibility of network services through a process named Service Function Chain (SFC) mapping, with which different network services are deployed over virtualized and shared platforms in data centers.

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
