Abstract

Background/Objectives: Significant amount of research and development has been made in the field of core network and it operates in hundreds Gigabits per second (Gbps) speed currently. But on seeing the growth in bandwidth demand in the access network which is exploding day by day, the only promising solution is to upgrade the access network. So it is essential to have an efficient access network that can operate at high functional speeds to support differentiated services. Methods: This paper proposes a novel TD_Optimum for improve the network performance and compares it with a DBA_GATE algorithm. The algorithm is employed by emulating an access network with the use of two 10G transceivers for 10G-EPON. The algorithm is tested for Triple Play services that include emulated voice, video and data packets. Findings: The algorithm is found to maintain a better tradeoff between throughput and delay as well as QOS, than the existing DBA_GATE algorithm. Application/Improvement: The 10G-EPON is a great boom in the optical technology and provides a great support to Video on Demand, High Definition TV (HDTV), Online gaming, Telemedicine, Video Conferencing. The ardent task of this research is to implement in this algorithm using 40Gbps supported NIC cards (next generation optical networks) and measure the variation of throughput and the average delay with an efficient network monitoring tool. The purpose is to provide huge bandwidth for packet transfer without dropping of voice, video and data packets. The emulation of this scenario in future can be switch over to Labview or Opnet software for further improvements.
