Customizable Deployment of NFV Services

Journal of Network and Systems Management, 2021
Network Functions Virtualization (NFV) promotes a paradigm shift in the core network, by enabling the execution of network functions on a virtualized software plane instead of on dedicated hardware. Despite its benefits, NFV introduces new challenges, of which we highlight those related to the deployment of virtualized network services.

SPaaS-NFV: Enabling Stream-Processing-as-a-Service for NFV

2018 IEEE 8th International Symposium on Cloud and Service Computing (SC2), 2018
Network Function Virtualization (NFV) as new network paradigm provides an opportunity to accelerate network innovation in the next generation mobile network (MN). The monitoring, in this case, helps the analysis and gives better insights into the network function in real time.

NFV-Enabled Network Slicing

2018 IEEE International Conference on Communications Workshops (ICC Workshops), 2018
Next generation (5G) networks are expected to support multiple types of services and various customer segments, which can be realized through the network slicing and network function virtualization (NFV) techniques. Through these techniques, a single physical network can be partitioned into multiple virtual networks providing cost-effective, flexible ...

A fault management system for NFV

2018 International Conference on Information Networking (ICOIN), 2018
NFV (Network Functions Virtualization) is attracting attention as a next-generation network technology. NFV is a technology allows existing network devices based on hardware to be resiliently managed by virtualization technology. Each network function, VNF (Virtual Network Function), runs on virtualized general purpose hardware and it is organized into

NFV-GUARD: Mitigating Flow Table-Overflow Attacks in SDN Using NFV

2021 IEEE 7th International Conference on Network Softwarization (NetSoft), 2021
Software Defined Networking (SDN) has recently drawn attention by changing the network control paradigm. SDN devices handle the network traffic based on entries stored in their flow table. However, due to the flow table’s limited size, attacks such as DDoS can cause the table to overflow. Some of the current table overflow mitigation methods distribute

Service assurance architecture in NFV

2017 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN), 2017
Service Assurance (SA) is a significant part of Network Function Virtualization (NFV) to enable automated and efficient service delivery from end to end (E2E). In NFV, SA should be integrated into the design and development loop from the beginning. However, it sees slower pace than other NFV management and orchestration (MANO) components.

Transparent flow migration for NFV

2016 IEEE 24th International Conference on Network Protocols (ICNP), 2016
NFV together with SDN provides the flexibility for NFs in the way that they are deployed and managed. The flexibility enables dynamical scale in and scale out through migrating in-process flows among NFs. Due to stateful packet processing in NFs, flow migration has to guarantee loss-free and order-preserving for both flow states and packets.

Causality inference for failures in NFV

2016 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2016
In this paper we consider a root-cause analysis framework for NFV infrastructure. As monitoring machinery for NFV has matured the next step is to leverage on such data to automatically optimize failure detection, analysis, and overall resiliency.

Implementing NFV system with OpenStack

2017 IEEE Conference on Dependable and Secure Computing, 2017
Network Function Virtualization (NFV) is a promising approach for service providers to reduce CAPEX and OPEX and has drawn a lot of attention from vendors. Service Function Chaining (SFC) provides the ability to define a sequence of network services.

Orchestrating distributed mode of NFV

2016 IEEE NetSoft Conference and Workshops (NetSoft), 2016
This paper introduces the Distributed NFV Orchestrator (DiNO). DiNO integrates and orchestrates Software-Defined Networking (SDN) and Network Function Virtualization (NFV) in a physically and logically distributed manner and optimizes their service quality and resource utilization.
