Abstract
dc:description.abstractWith the continuous expansion of network infrastructure and deployment of applications sensitive to Quality-of-Service, network measurement plays a major role in both network planning and management. Accurate measurement of various network parameters, e.g., available bandwidth, link capacity, delay, packet loss and jitter, provides a positive impact for effective traffic engineering, Quality-of-Service (QoS) routing, optimization of end-to-end transport performance, and link capacity planning. For network measurement, there exists several proactive estimation tools based on either probe-gap model or probe-rate model that estimate path related attributes. Most of these tools that have been implemented can measure tight-link capacity (smallest available bandwidth) and/or narrow-link capacity (smallest link capacity) between a source node and destination node along a particular path. However, network measurement also has negative impacts on the cross traffic that induces extra queuing delay and packet loss for the legitimate data traffic that results in a significant intrusion and in degree of erroneous estimation. In this thesis, a combined measurement tool for measuring both available bandwidth and link capacity using a combination of probing packets and ICMP probe packets is been proposed. A study of the proposed tool is presented. The proposed schemes provide acceptable accuracy, low overhead, and avoid over-estimation.
