An architecture of next generation access network namely orthogonal frequency division multiplexing passive optical network was presented, which has high spectrum efficiency, fine bandwidth granularity and low cost. A novel efficient dynamic bandwidth allocation algorithm based on orthogonal frequency division multiplexing passive optical network namely fixed cyclic polling in pipeline dynamic bandwidth allocation algorithm was investigated. To meet the quality of service requirements under multi-services access scenario, two level bandwidth allocation mechanisms, bandwidth pre-request for expedited forward service and the smallest bandwidth request allocated the first principle for assured forwarding and the best effort services were applied in this algorithm. A simulation was conducted to study the performance of fixed cyclic polling in pipeline dynamic bandwidth allocation algorithm in orthogonal frequency division multiplexing passive optical network. The results show that the proposed algorithm supports expedited forwarding services with low packet average delay and low jitter, balances priority and fairness between assured forwarding services and best effort services, and achieves bandwidth allocation fairness among different optical network units in the same priority. Compared with the traditional dynamic bandwidth allocation algorithms, fixed cyclic polling in pipeline algorithm meets the quality of service requirements excellently, and adapts orthogonal frequency division multiplexing passive optical network better with higher bandwidth efficiency and lower algorithm complexity.
