1.1 THE MOTIVATION FOR PON
One of the most critical decisions for any business involves the purchase of capital equipment. The two important factors which influences this decision are equipment cost and the resulting revenue potential. Service providers face this decision when upgrading existing access networks, and they want to minimize the cost and maximizing the revenue potential. Thus, the most important decision the service provider makes when purchasing network equipment ....etc

ABSTRACT
PON-based access networks envisage the demonstration of scalability to allow gradual deployment of time and
wavelength multiplexed architectures in a single-platform without changes in fibre infrastructure and also
highly-efficient bandwidth allocation for service provision and upgrade on-demand. This is achieved by the
application of coarse-fine grooming to route reflective-ONUs of time and wavelength PONs collectively and the
development of MAC protocols enabling the OLT to dynamically assign available time slots among O ....etc

Synthesis Control of Switching Topologies of Converters

ABSTRACT
An intelligent inference pipeline for the control of a dc-dc buck-boost converter was designed and built using a semi-custom. The switching topologies of the converter was mapped into a look-up table that was synthesized into controllers, and detectors for building complete instrument systems.
Two different topologies are called buck“boost converter. Both of them can produce an output voltage much larger (in absolute magnitude) than the inpu ....etc

PON Topologies

There are several topologies suitable for the access network: tree, ring, or bus. A PON can also be deployed in redundant configuration as double ring or doubletree; or redundancy may be added only to a part of the PON, say the trunk of the tree. For the rest of this article, we will focus our attention on the tree topology; however, most of the conclusions made are equally relevant to other topologies.All transmissions in a PON are performed between Optical Line Terminal (OLT) and O ....etc

Multi-path Dissemination in Regular Mesh Topologies

Abstract:

Mesh topologies are important for large-scale peer-to-peer systems that use low-power transceivers. The Quality of Service (QoS) in such systems is known to decrease as the scale increases. We present a scalable approach for dissemination that exploits all the shortest paths between a pair of nodes and improves the QoS. Despite the presence of multiple shortest paths in a system, we show that these paths cannot be exploited by spreading the messages over the paths in a ....etc

During recent years, peer-to-peer (P2P) file-sharing sys- tems have evolved in many ways to accommodate growing numbers of participating peers. In particular, new features have changed the properties of the unstructured overlay topology formed by these peers. Despite their importance, little is known about the characteristics of these topologies and their dynamics in modern file-sharing applications. This paper presents a detailed characterizat ....etc
