Abstract:

A new S/G/m/FCFS queuing model for GPON system is proposed to analyze the access delay for dynamic bandwidth allocation algorithms. An evaluation for both Static Estimation Bandwidth allocation (SEBA) and Dynamic Estimation Bandwidth allocation (DEBA) are carried out based on the proposed queuing model. To save bandwidth resource and improve network performance, the estimation factor of DEBA can be adjusted dynamically according to the traffic load. Simulations verify that DEBA is superior to SEBA for obtaining lower access delay and mitigating congestion effectively.
