Network function consolidation in service function chaining orchestration
2016 IEEE International Conference on Communications (ICC), 2016Network 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.

Subscriber aware dynamic service function chaining
Computer Networks, 2021Abstract 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.

Energy-Aware Service Function Placement for Service Function Chaining in Data Centers
2016 IEEE Global Communications Conference (GLOBECOM), 2016Nowadays, 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

Joint Optimization of Service Function Placement and Flow Distribution for Service Function Chaining
IEEE Journal on Selected Areas in Communications, 2017In 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.

Availability-aware mapping of service function chains
IEEE INFOCOM 2017 - IEEE Conference on Computer Communications, 2017Network 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), 2020Service 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

A scalable metaheuristic for service function chain composition
2017 IEEE 9th Latin-American Conference on Communications (LATINCOM), 2017Network Functions Virtualization (NFV) is a new network paradigm that has been strongly promoted from both scientific community and telecom industry, where network functions (NFs) such as firewalls, load balancers, gateways among others, are virtualized, isolated from middleboxes and housed on one or more industry standard computing nodes.

Service function chaining policy compliance checking
NOMS 2018 - 2018 IEEE/IFIP Network Operations and Management Symposium, 2018The end-to-end network services often requires various Network Functions (NFs) that provides the L4-L7 functionality. Service Function Chaining (SFC), which consists of an ordered set of NFs, and Software Defined Network (SDN), which has global view of the network and programmability, easily enable the creation of network services.

HybridSFC: Accelerating Service Function Chains with Parallelism
2019 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN), 2019Network 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 ...
