Today the Internet offers a single path between end-systems even though it intrinsically has a large multiplicity of paths. This paper proposes an evolutionary architectural framework "BANANAS" aimed at simplifying the introduction of multipath routing in the Internet. The framework starts with the observation that a path can be encoded as a short hash(More)
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)
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)
— 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(More)
In this paper we describe QNAT, a software tool developed at Indian Institute of Technology, Kanpur, India, for the analysis and simulation of queueing networks. Arbitrary configurations of open or closed networks of multi-server queues with infinite or finite capacity, fork-join queues with or without synchronization queues can be analyzed or simulated(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)
