Designing network infrastructure for an e-learning cloud

Abstract

This paper discusses the aspect of designing network infrastructure for e-learning private clouds. The aim is to build a comprehensive, stable, scalable, reliable and flexible infrastructure that will effectively support all models of deploying cloud computing services in academic environment. Main component of the infrastructure is a network organized in three logical layers: core, distribution and access. Functions of the access and distribution layer are integrated in the cloud. OpenFlow protocol was used as an interface for software switches in cloud. The implementation of the model and the system for network management in an educational institution are described in details. The developed infrastructure can host numerous services for learning and collaboration for both students and teaching staff
