The Next Generation Access Networks (NGAN) are the new step forward to deliver broadband services and to facilitate the integration of different technologies. The real challenge faced by 10GEPON new standard IEEE 803.3av is to upgrade the channel capacity for both upstream and downstream channels gracefully, while maintaining the logical layer intact ensuring the coexistence with legacy 1 Gb/s (IEEE...
Ethernet passive optical networks (EPON) are a cost-effective solution for the bottle-neck problem in the access network. An open issue for this technology is the bandwidth allocation over the upstream channel in order to provide differentiated services, fairness and efficiency. Several algorithms for dynamic bandwidth allocation in EPON have been proposed, but very few of them address the possibilities...
