TLDR
The article presents an Ethernet gigabit PON (GPON) system aligned with the philosophy of the evolving FSAN (full service access network) ITU-T specification, which focuses on the efficient support of any level of quality of service.Abstract:
The standardization of passive optical networks capable of transporting Ethernet frames at gigabit-per-second speeds, currently in progress in both ITU-T and IEEE, constitutes a major milestone toward cost-effective photonization of the last (aka first) mile. The article presents an Ethernet gigabit PON (GPON) system aligned with the philosophy of the evolving FSAN (full service access network) ITU-T specification, which focuses on the efficient support of any level of quality of service. The intelligence of this system, in terms of traffic quality guarantees, lies in the MAC protocol, which controls the distributed multiplexing/concentration function by allocating variable length slots to every user of the shared upstream (toward the network) medium. The way transport of information is organized in an ITU-T GPON system and the operation of a MAC protocol that preserves all QoS guarantees are presented and evaluated.read more

Method for mapping service flow to service transmission path and optical network terminal
TL;DR: The method comprises: optical network terminal saves message features of different services, and after receiving service stream, maps the service stream matching the message feature into the appointed service transmission channel.

A hybrid dynamic bandwidth allocation scheme operating with IACG and cooperative DBA for converged fronthaul networks
TL;DR: In this article , a hybrid dynamic bandwidth allocation (DBA) scheme for converged fronthaul that combines a status reporting DBA and a cooperative DBA is proposed, which is evaluated in terms of average upstream delay and percentage of frame loss.
