Passive optical networks (PONs) represent a promising solution for modern access telecommunication networks. These networks are able to meet the increasing demands on transmission rate for demanding multimedia services, while they can offer typical shared transmission speed of 1.25 or 2.5 Gbps. The major role in deploying optical distribution networks ODNs plays the maximum attenuable loss, whi...

A Passive Optical Network (PON) is a network technology for deploying access networks based on passive optical components. In a single PON access network, the client terminals are connected to a Central Office through optical splitters and interconnecting fibers where each splitter splits in equal parts the input optical signal coming from the Central Office over its different output fibers. In...

Title of dissertation: NETWORK STATE ESTIMATION VIA PASSIVE TRAFFIC MONITORING Ryan Lance, Doctor of Philosophy, 2005 Dissertation directed by: Professor James Yorke Department of Mathematics We propose to study computer network traffic as a dynamical system, with the intent of determining how predictable the traffic is over short time scales. We will use passive measurements from high capacity...

The complexity of network systems and the heterogeneity of end systems will make networks increasingly difficult to manage. To understand the operational details of networks it is imperative that sufficient information on their behavior is available. This can be achieved through network measurement. Passive network measurement systems typically collect packet traces that are then stored in trac...

In the Internet today, users and applications must often make decisions based on the performance they expect to receive from other Internet hosts. For example, users can often view many Web pages in low-bandwidth or highbandwidth versions, while other pages present users with long lists of mirror sites to chose from. Current techniques to perform these decisions are often ad hoc or poorly desig...
