We suggest an immediate allocation with colorless grant (IACG) method for dynamic bandwidth of a gigabit passive optical network (GPON) system. The suggested is based on the GigaPON Access Network (GIANT) media access control (MAC) method. IACG can assign transmission regardless value scheduling counter, whereas GIANT MAC only when counter has 1. Also, unlike method, utilizes unallocated remainder bandwidth. At end scheduling, assigns to each unit (ONU) equal share. Using computer...

In this paper, we propose a dynamic bandwidth allocation with high utilization (DBAHU) algorithm in order to utilize the unused of service class. DBAHU is based on simple and feasible (SFDBA) algorithm. Like SFDBA, uses common available byte counter down for multiple queues However, class, an can be negative unlike SFDBA. Also, remainder class added counters other classes who require more bandwidth. Using simulations, show that superior SFDBA mean delay frame variance.

In this paper, we propose a simple and feasible dynamic bandwidth allocation (SFDBA) algorithm in order to utilize the unallocated achieve implementation feasibility. SFDBA is based on an immediate with colorless grant (IACG) but uses only single available byte counter down for multiple queues of same service class. Since share counter, queue can be utilized by another queues. For better fairness, changes starting scheduling round-robin manner. Using simulations, show that superior existing...
