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-based passive optical networks (EPON) are being considered as the best candidates for the next generation broadband access networks. Several algorithms for dynamic bandwidth allocation in EPON have been proposed, as this is an open issue that was left out of the scope of the standard IEEE 802.3ah. Very few of those works address the possibilities for an on-the-fly (immediate) distributed...
