Time and Memory Complexity of Next-Generation Passive Optical Networks in NS-3

Abstract

Passive optical networks (PONs) offer a high network capacity and densified coverage at the cost of high capital expenditure. That fact is why operators use a shared infrastructure with one fiber for more customers in a split ratio. Deploying a passive optical network requires capital, but the operators can use a simulation tool to verify the physical layer parameters. The higher layers are less relevant for operators than for researchers. In this paper, we provide a basic simulation topology with downstream and upstream services. In real networks, the services control optical line termination (OLT), but in a simulation, it requires a router after optical line termination. We demonstrate a comparison of the time and memory complexity for low-rate services in 10G passive optical networks with different split ratios in Network Simulator 3 (NS-3).
