Next generation broadband access networks are gaining more interests from many key
players in this field. The demands for longer reach and higher bandwidth are among the …

In recent years, there has been an increasing trend towards extending the coverage of
passive optical networks (PONs) over large geographical areas. Long-reach PONs …

In a dynamic bandwidth assignment (DBA) scheme for a passive optical networks (PON), a
polling mechanism with higher polling frequency helps OLT to accurately enquire the ONU …

In order to ensure fairness of each optical networks unit (ONU) in access network and meet
quality of service (QoS) requirements of differentiated service such as voice, video and data …

Abstract Passive Optical Networks (PON) have emerged as an important fiber-based access
network alternative to DSL, Cable, and other access networks. Some of the limitations of …

Bandwidth allocation is one of the critical issues in Ethernet passive optical networks
(EPONs). To achieve good network performance and thus provide guaranteed network …

In this article, new Dynamic Bandwidth Allocation (DBA) algorithms which give high priority
to some ONUs corresponding to important agencies are studied in order to manage …

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 …

Bandwidth assignment is a key issue in optical access networks, so an efficient mechanism
is required for dynamic distribution of limited resources in the uplink channel among …

As network speeds (capacities) are increasing, it has become more important to reduce
network power consumption. In passive optical networks, reducing the buffer size in …
