A passive optical network (PON) is a highly capable access network that effectively converges several service providers, without suffering from any bandwidth deficiency. However, a PON consisting of a single optical line terminal (OLT) for multiple service providers increases the computational complexity for data packet processing in the OLT, resulting in a longer time delay and more packet loss. A multi-OLT PON-based access network is an effective solution for reducing the computational complexity of data packet processing in a hybrid network of multiple service providers. The most important issue concerning the multi-OLT PON is the sharing efficiency of upstream channels among multiple service providers having different packet lengths and data rates. In this paper, we propose a dynamic bandwidth allocation algorithm called adaptive limited dynamic bandwidth allocation for multi-OLT PON (ALDBAM). The …
