Dynamic Bandwidth Allocation (DBA) is a major research challenge in the migration of
Passive Optical Networks (PON) systems towards Long Reach PON, especially when hybrid …

While in recent years backbone bandwidth has experienced substantial growth, little has
changed in the access network.“Last mile” still remains the bottleneck between a high …

Upstream dynamic bandwidth allocation (DBA) for Gigabit Passive Optical Networks (GPON)
is an important design problem since the shared uplink carries many bursty streams of …

In a Passive Optical Network (PON), the possibility of smooth upgrading the network
infrastructure is an important requirement for network providers as it allows to minimize initial …

For an efficient bandwidth management among the optical network units in the upstream link
of a passive optical network (PON), it is necessary to use a dynamic bandwidth assignment …

These days there is a clear trend toward extending the reach of passive optical networks to
cover large geographical areas, which enables reduction of the number of central offices …

A passive optical network (PON) combines multiple service providers' in a ubiquitous city (u-
City) without suffering from a bandwidth bottleneck. Multiple optical line terminals (multi …

Long-reach passive optical networks (LR-PONs) have been considered to be promising
solutions for future access networks. In this paper, we propose a distributed medium access …

The extended network span of next-generation long-reach passive optical networks (LR-
PONs) results in extremely long propagation delays that severely degrade the performance …

A software-defined hybrid passive optical network (HPON) architecture is proposed, in which
multiple PON systems using various physical layer (PHY) multiplexing technologies can …
