Paper Abstract

Passive optical networks (PON) is being considered as a promising solution for next generation broadband access network due to the convergence of broad bandwidth and low-cost fiber infrastructure along with its ability to successfully support IP-based multimedia applications. PON system has its individual bandwidth allocation mechanism compared with core network allocating bandwidth based on service priority level. However, no uniform bandwidth allocation mechanism from access network to care network. In this paper we propose a novel method of extended bandwidth allocation mechanism among multi-PON systems; then extended dynamic bandwidth allocation (DBA) algorithm in a Gigabit-capable PON (GPON) system for core network is presented. The bandwidth management mechanism among multi-optical line terminals (OLTs) can provide an end-to-end bandwidth guarantee for data transmission. We conduct detailed simulation experiments to study the performance and validate the effectiveness of the proposed method.
