| Abstract | Passive Optical Networks (PONs) are assumed to be green access technology; however, there is still big room to maximize its energy saving. Therefore, there are significant research efforts in industries and academia. To evaluate and compare different types of energy efficiency solutions in PON, mathematical models are already studied energy efficiency. However, mathematical models are complex and require simple assumptions; so that, simulation models are preferred to obtain big picture and detailed analysis of PON. One of the widely applied approaches to make PON energy efficient is sleep mode mechanism, in which some of the components in PON equipment are turned off whenever possible. However, sleep mode could deteriorate Quality of Service (QoS) performance of PON traffic (e.g. packet might experience delay, throughput might be reduced). Therefore, it is significantly important to take into consideration these QoS factors while proposing any sleep mode algorithm. To the best of our knowledge, to date, there are a few existing research efforts to understand energy saving and TCP traffic performance in PON at the same time. In this paper, we develop a novel simulation and modeling framework for Ethernet PON (EPON) with sleep mode capability using OPNET Modular; so that, all network traffic performance could be analyzed and wide range of results could be produced. In this paper, we have analyzed the performance of TCP throughput under a very widely used sleep interval deciding algorithm used for TDM-PONs (e.g. EPON). Our findings show that depending on parameters used in sleep interval deciding algorithms and available traffic in EPON at a given time, sleep mode might affect TCP throughput remarkably. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
