OPENFLOW VIRTUALIZATION: A DECLARACTIVE INFRASTRUCTURE OPTIMIZATION SCHEME FOR HIGH PERFORMANCE COMPUTING

Contempriarily, networks have become a critical component of all infrastructures in High Performance Computing (HPC) environments. With the wide acceptance of cloud computing, 4G long term eveolution (LTE), Smart grid integrated iTs and other internetworking applications, a highly optimized scheme is recommended. This scheme will give network operators more control of their infrastructure, allowing customization and optimization, thereby reducing overall capital and operational costs. This paper presents Openflow virtualization in layer 2 switch which serves as a uniform vendor interface between control and data planes. The operating system logically constructs and presents a logical map of the entire network to services or control applications implemented on top of it, hence slicing and virtualizing the underlying network. With this, a Synthesis Service Differenciation (SSD) model was introduced by writing internetwork operating system (IOS) scripts that manipulates the logical map of the switch slice with IP address ranges. The result is an increased ability to quickly introduce new services and to adapt the network faster when service changes are required in HPCs.
