Generalized Processor Sharing (GPS) Techniques

Abstract

In this era of service integration and proliferation of value-added services, ICT networks have traffic volume that tends to overwhelm network resources. Satisfaction of quality of services (QoS) is usually difficult especially with static network resources. A flexible and popular technique, Generalized Processor Sharing (GPS), provided an effective and efficient utilization of the available resources at the face of stringent and varied QoS requirements. This paper, therefore, presents the comparison of two GPS techniques – PGPS and CDGPS – based on performance with limited resources in an isolated node. The better performing PGPS technique was further investigated under varying QoS, resources and traffic load. PGPS resource utilization behaviors for given QoS parameters (delay, and reliability) were presented and applied in the realization of a network performance management system at the ETF centre of excellence in Communication Networking, University of Nigeria, Nsukka.
