In this paper we describe an approximate method for the analysis of an open network of finite capacity queues. Finite buffer capacities at the nodes introduce blocking of jobs that finish service at a node and find that the destination node is full at that time. When this happens, we assume that the blocked job is held at the server of the queue where it(More)
The complexity and dynamics of the Internet is driving the demand for scalable and effective network control. This paper proposes a collaborative on-line simulation architecture to provide pro-active and automated control functions for networks. The general model includes autonomous on-line simulators which continuously monitor/model the network conditions(More)
As the Internet infrastructure grows to support a variety of services, its legacy protocols are being overloaded with new functions such as traffic engineering. Today, operators engineer such capabilities through clever, but manual parameter tuning. In this paper, we propose a back-end support tool for large-scale parameter configuration that is based on(More)
We propose BANANAS a connectionless framework for both intra domain and inter domain tra c engineering TE in the Internet The key contributions of this framework are a it allows the source to discover multiple paths and decide on how to split tra c among paths assuming simple for warding extensions in a subset of routers b it does not require signaling or(More)

In this paper, we address the issues associated with the dynamic optimization of OSPF weights. For this work we have chosen the packet loss rate in the network as the optimization metric as it is a good indicator of congestion in the network and also impacts the performance of the underlying applications. The packet loss rate has been formulated in terms of(More)
In this paper, we present a scheme for minimizing the packet loss in an OSPF network by optimizing link weights using Online Simulation. For this work we have chosen packet loss rate in the network as the optimization metric as it is a good indicator of congestion and impacts the performance of the underlying applications. We have formulated packet loss(More)
Traffic Engineering (TE) deals with the task of mapping traffic flows to the routes in an existing physical topology to improve the performance of operational IP networks. A desirable traffic engineering solution must provide network operators a precise control over the traffic flows within their routing domains. This enables the network operators to(More)
