—Ethernet passive optical networks (EPONs) have emerged as the one of the most promising candidates for next-generation access networks. These new architectures couple low-cost optics with advanced edge electronics to offer vastly improved scalability over competing digital subscriber line and cable modem offerings. This paper proposes several novel(More)
ecently, the interest in broadband satellite networks has grown rapidly. Advances in transmission technology have led to the availability of low-cost earth terminals with interfaces to standard terrestrial networks. The relative ease of deployment and superior remote access capabilities of satellite networks are envisioned to provide bandwidth on demand to(More)
Given the increasing adoption of DWDM networking technology, there is now a growing need to address distributed inter-domain lightpath provisioning issues. Although inter-domain provisioning has been well studied for packet/cell-switching networks, the wavelength dimension presents many additional challenges. To address this challenge, a detailed(More)
— Ethernet passive optical networks (EPONs) are being designed to deliver multiple services and applications, such as voice communications (VoIP), standard and high-definition video (STV and HDTV), video conferencing (interactive video) and data traffic access network. However, most of the current work focuses on inter-ONU dynamic bandwidth allocation (DBA)(More)
An efficient resource allocation is a fundamental requirement in high performance computing (HPC) systems. Many projects are dedicated to large-scale distributed computing systems that have designed and developed resource allocation mechanisms with a variety of architectures and services. In our study, through analysis, a comprehensive survey for describing(More)
— Smoothed Round Robin (SRR) is an O(1) scheduler that efficiently schedules flows based on flow granularity leading to short-term fairness. We propose DS2R2 – Delay Sensitive Smoothed Round Robin Scheduler that enhances SRR by adhering to delay constraints of flows. Scalability and performance issues of DS2R2 for high-speed optical networks are considered.
Storage traffic. The test-bed is based on the recently proposed Strongly connected Light-trail (SLiT) technology that enables the triple features of dynamic provisioning, spatial sub-wavelength grooming and optical multicasting – that are quintessential for provisioning of the aforementioned emerging services. SLiT technology entails the use of a(More)
