A framework for campus wide network using cluster virtualization and transmission rate management

Abstract

With cluster virtualization, coexistence of multiple virtual servers in a shared network infrastructure without requiring unified protocols, applications, and control and management plane is realizable. In this case, Delocalized Software Defined Networking (DSDN) was use to enhanced the performance of campus cloud service network. This offers virtualized resource management thereby saving cost for enterprise organization(s). Also, for optimizations of bandwidth link in such wireless network, transmission rate management is needful. In this paper, a conceptual framework for campus wide network is presented leveraging the two highlighted perspectives. Detailed algorithms that ensures network and traffic stability on a typical Campus Wide network substrate is described. Using Riverbed Modeler event based simulation; the algorithms for computational intelligence were migrated from switch-centric to server-centric cloud datacenter network topology. This architecture is recommended for enterprise web application services deployment in Campus networks. Furthermore, Admission Control Synthesis Architecture (ACSA), transmission rate management by scheduling, and virtualization implementation with IBM Flex System manager were extensively analyzed in the proposed framework. A feasible production testbed (CWN FiConn) for unified services is presented as a validation/proof of concept showing over 50.57% efficiency in terms of throughput, resource utilization of about 31.25% and near zero network latency when compared with a legacy FatTree model. The perspective offered in this work demonstrates that campus networks can be re-engineered for enterprise efficiency.
