Fair sharing using service-level agreements (SLAs) for open access in EPON

Ethernet passive optical networks (EPONs) are an attractive solution for meeting the broadband access requirements of residential users. Open access is a regulatory requirement in many countries which mandates that the access infrastructure must be open to various service providers for free competition. Thus, different service providers may cater services to same or different users using the same shared access channel. Open access demands fairness in the use of network resources among sharing entities, namely service providers and end users. In this study, we investigate scheduling algorithms for fair bandwidth sharing in the context of open access for EPONs.
