| dc.description.abstract | Traditional network architecture is facing a revolution. The Software-Defined Networking (SDN) and Network Functions Virtualization (NFV), two new network concepts have been proposed, network equipment manufacturers, telecom operators, IC design house, have invested a lot of research resources, participation in the development of specification.
SDN decouples the control plane and data plane, through the Controller application for centralized network management. Currently OpenFlow which promote by Open Networking Foundation (ONF) is the mainstream SDN communication protocol and it as a communication of control plane and data plane. European Telecommunications Standards Institute (ETSI) established NFV Industry Specification Group (ISG) were NFV technology research and specification, aimed at all kinds of network components such as: routers, firewalls, load balancing and other network functions, from a specific hardware device pulled out, the use of virtualization technology, convert to Virtual Network Function (VNF) and through software approach, deployed in the NFV Infrastructure (NFVI).
In this paper, according to the NFV Architecture Framework proposed by ETSI to build a Linct (Large-scale Intelligent NFV / SDN Cross -domain Testbed) on National Central University (NCU), National Cheng Kung University (NCKU) and National Center for High-performance Computing (NCHC) and design and implement NFV resource Orchestrator - Linct Orchestrator, to monitor resource utilization and system status from NFVI and VNF, provide VNF load balancing and high availability module. This paper proposed Vector-Based VNF Deployment Mechanism for NFVI Load Balance (VBVD) mechanism, this mechanism will be calculated based on each NFVI current resource utilization, to choose the most appropriate NFVI and deploy VNF on it, in order to achieve load balancing for all NFVI in testbed and optimize the use of resources and avoid resources overloading for single NFVI.
