In this paper, a distributed Dynamic Bandwidth Allocation (D-DBA) scheduling mechanism for star-ring protection architecture is proposed in Ethernet Passive Optical Networks (EPONs). The D-DBA mechanism can effectively resolve the idle period problem and reduce overload of OLT in traditional DBA mechanism. We perform exhaustive simulation experiments to study the performance and validate the usefulness...
During the last years so-called ``Thin Client'' architectures have become very popular. Thin Clients are simple end user devices, which are provided with content and services by powerful servers. Originally this concept was developed for Local Area Networks (LANs), which provide a high Quality of Service. If they are used in Wide Area Networks (WANs) they need to be adjusted accordingly in order to...
Many real-time communication protocols have been studied to guarantee the communication requirements of distributed real-time systems. But, current techniques lack all or most of these requirements specially bounded message delivery time. In this paper we have proposed a Mac layer protocol called RDM+ with concepts similar to Round Data Mailer multi layer protocol. Our simulation results show that...
