Partially Symmetric Service Function Chains
2019 2nd IEEE Middle East and North Africa COMMunications Conference (MENACOMM), 2019With 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, 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. With

Order dependency-aware service function placement in service function chaining
2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017In 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), 2020In 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), 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.

Coordinated Allocation of Service Function Chains
2015 IEEE Global Communications Conference (GLOBECOM), 2014Network 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 ...

Service Function Chaining in Wildfire Scenarios
2021 IEEE 7th International Conference on Network Softwarization (NetSoft), 2021Mission Critical Services (MCS) are associated with public safety networks and their support has been progressively introduced in LTE/5G standards. MCS are composed by distinct functions that are required for voice and critical data communications, along with strict security requirements.

Hierarchical Service Function Chaining (hSFC)
2018Hierarchical Service Function Chaining (hSFC) is a network architecture allowing an organization to decompose a large-scale network into multiple domains of administration. The goals of hSFC are to make a large-scale network easier to reason about, simpler to control and to support independent functional groups within large network operators.

Resilient allocation of service Function chains
2016 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN), 2016Network 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 ...

Embedding Dependence-Aware Service Function Chains
Journal of Optical Communications and Networking, 2018Network function virtualization (NFV) provides an effective way to decouple network functions from the proprietary hardware, allowing the network providers to implement network functions as virtual machines running on standard servers. In the NFV environment, an NFV service request is provisioned in the form of a service function chain (SFC).
