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).

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.

Service Chaining for Hybrid Network Function
IEEE Transactions on Cloud Computing, 2019In the Service-Function-Chaining (SFC) enabled networks, various sophisticated policy-aware network functions, such as intrusion detection, access control and unified threat management, can be realized in either physical middleboxes or virtualized network function (VNF) appliances.

Container-Based Service Function Chain Mapping
2019 SoutheastCon, 2019Network function virtualization (NFV) allows service provides to implement network processing functionality in software using standard computing servers. As such, this approach precludes the need for deploying costly and proprietary hardware-based networking devices, i.e., black boxes, greatly reducing infrastructure and operational costs.

Breaking Service Function Chains with Khaleesi
2018 IFIP Networking Conference (IFIP Networking) and Workshops, 2018Network 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.
