Dynamic Bandwidth Allocation using Sequential Channel Selection for Hybrid WDM/TDM EPON
Motivation
Hybrid WDM/TDM PON is identified an access solution where the user traffic demands can be met in pay-as-you-grow paradigm, exploiting merits of current TDM PONs and future WDM PONs. Dynamic Bandwidth Allocation (DBA) for Hybrid WDM/TDM PON is challenge for any Medium Access Control (MAC) algorithm to justify the bandwidth demands of individual terminal equipment, i.e., Optical Network Unit (ONU).
Current Progress
We propose a DBA algorithm with Sequential Channel Selection (SCS) keeping the scalability, fairness, simplicity (i.e., not to over load Optical Terminal Equipment (OLT) s performance) and robustness issues upfront for Hybrid WDM/TDM PON.
The main idea of SCS is to serve more number of TDM PONs (i.e., increased scalability) by allocating bandwidth dynamically with lesser tunable transceivers (i.e., reducing the overall cost of transceivers in the network) at the OLT. Wavelength channels for each PON are allocated statically and the OLT tunes its transceivers to each channel in round robin fashion providing bandwidth to each PON dynamically.
