IEEE Spanning Tree Protocol (STP) is a layer-2 protocol which ensures a loop free topology in Metro Ethernet networks. It is based on Minimum Spanning Tree solution that involves determining the links which can join all the nodes of a network together such that the sum of the costs of the chosen links is minimized. In STP, all customers need to use the same(More)
Spanning Tree Protocol (STP) is an IEEE approved standard that provides a loop-free forwarding topology in Ethernet networks. When we deal with large scale networks, we need high bandwidth links close to the Root node of the tree. In STP, all customers need to use the same spanning tree and there isn’t any traffic engineering mechanism for load(More)
IEEE STP is a layer-2 protocol which provides a loop-free connectivity across various network nodes. STP does this task by reducing the topology of a switched network to a tree topology where redundant ports are blocked. This action ensures there is a unique path from any node to every other node. Blocked ports are then kept in a standby mode of operation(More)

Major Challenge for deploying Ethernet in metro area networks is to guarantee the quality of service and traffic engineering requirements. In the literature, there are many forwarding strategies proposed by researchers to overcome this challenge. One significant difficulty in assessing and comparing the different forwarding strategies proposed is the lack(More)
The Spanning Tree Protocol (STP) is an approved standard that provides a loop-free active topology in Ethernet networks. The main idea in the STP is reducing the topology of a network to a tree topology by blocking the redundant ports. The lack of any traffic engineering mechanism for load balancing in the STP results in uneven traffic distribution and(More)
This paper addresses the problem of intelligibility and quality improvement for the speech corrupted due to reverberation. Several speech de-reverberation algorithms (both single- and two-channel methods) are studied and compared. Based on this study, we propose some hybrid methods to improve both intelligibility and quality of reverberated speech. The(More)
