A Multi-Threaded Dynamic Bandwidth and Wavelength Allocation Scheme With Void Filling for Long Reach WDM/TDM PONs

Multi-OLT and multi-wavelength PON-based open access network for improving the throughput and quality of services

“…In [8], a multi-threaded scheduling algorithm is considered for a hybrid WDM/TDM PON. The scheduling scheme of the multiple wavelengths allows sending multiple transmissions at a same time.…”

Reducing attendance time in LR-EPONs with differentiated services

“…A bandwidth grant is allocated into void if the void size is greater than or equal the bandwidth grant. In [2], authors extended RBVF to allow bandwidth grant to be divided at most p chunks and hence make better void utilization. We will refer to their work as request based partial void filling (RBPVF).…”

Blind void filling in LR-EPONs: How efficient it can be?

“…In [6], authors proposed a request based partial void filling (RBPVF) scheme to further improve RBVF. Their algorithm is a mix between RBVF and multi-thread polling (MTP) [4].…”

“…The negative effect of such voids motivates many researchers to either reduce their size by proposing new DBA schemes [4], [2] or trying to fill these voids with request based bandwidth grants [5], [6]. The void filling techniques presented so far are request based void filling (RBVF).…”
