Abstract:
|
The evolution of the Ethernet passive optical
network (EPON) to the enhanced 10G-EPON standard looks
poised to maintain its position as the leading fiber to the
home technology worldwide. Fair bandwidth allocation will
be a challenge in the near future in plants where 1G and
10G customer premises equipment coexists. In this paper
we propose a distributed algorithm, distributed dynamic
scheduling for EPON (DDSPON), to dynamically allocate the
bandwidth requested by the user equipment with quality of
service (QoS) constraints. The proposed algorithm is scalable
and simple to re-configure, which facilitates a smoother
transition from legacy 1G to 10G networks. By using the
DDSPON, enhanced optical network units (ONUs) will take full
advantage of the 10 Gb/s rate while legacy 1G ONUs maintain
their service level agreement; as a result, the individual
performance is maximized for both groups of ONUs. We
also present an analytical model to evaluate the algorithm
performance in a coexistent 1G/10G network. Finally, we also
illustrate the enhancement of the DDSPON to provision the
QoS to different services under the DiffServ architecture.
Analysis and simulation results validate the effectiveness of
the proposed mechanisms. |
