The extended network spans of next generation long-reach passive
optical networks (LR-PONs) result in extremely long propagation
delays that severely degrade the performance of currently adopted
upstream bandwidth-allocation algorithms. This is because these
algorithms are based on bandwidth negotiation messages, frequently
exchanged between the central office and distant network units,
which become seriously delayed when the network is possibly
extended to hundreds of kilometers. This book addresses this
problem by proposing decentralized media access for these emerging
networks, allowing the network units to communicate with each other
and take turns accessing the upstream channel. This makes the
upstream bandwidth-allocation performance independent of the
network reach and enables sooner transmission of upstream packets.
The book also reviews some of the major contributions in this
field, and studies many challenges facing the decentralized scheme.
Through extensive simulation, the performance of the decentralized
scheme is evaluated in contrast with centralized schemes. In
addition, various improvement approaches are explored and further
research points are highlighted.
