The dis-aggregated passive optical network (PON) optical line terminal (OLT) architecture is attracting attention in academia and industry. This paper first reviews the evolution in dynamic bandwidth allocation (DBA) dis-aggregation. We further enhance the scalability of the dis-aggregated PON-OLT by reducing the bandwidth overhead of REPORT/GATE, the time division multiplexing (TDM) control information transferred between dis-aggregated DBA and the hardware platform. Our experiment verifies that the data compression based on basic integer coding can improve the scalability by 27% with acceptable processing time.

PON-OLT中的DBA分解，并通过REPORT / GATE压缩增强了可伸缩性[已邀请]

分解的无源光网络（PON）光线路终端（OLT）体系结构引起了学术界和行业的关注。本文首先回顾了动态带宽分配（DBA）分解的发展。通过减少REPORT / GATE的带宽开销，在分解DBA和硬件平台之间传输的时分复用（TDM）控制信息，我们进一步提高了分解PON-OLT的可伸缩性。我们的实验验证了基于基本整数编码的数据压缩可以在可接受的处理时间下将可伸缩性提高27％。
