— In this paper, we propose Layered TCP (LTCP for short), a simple layering technique for the congestion window response of TCP to make it more scalable in highspeed, high RTT networks. LTCP is a two dimensional congestion control framework-the macroscopic control uses the concept of layering to quickly and efficiently make use of the available bandwidth(More)
Dii-serv framework is receiving wide attention as an architecture for implementing service guarantees in the Internet. Current framework allows customers to mark their packets and the network provider to check them for conformance to service contracts. This paper looks at the impact of marking strategies employed by aggregated sources (customers) on the(More)
—The frequent attacks on network infrastructure, using various forms of denial of service attacks, have led to an increased need for developing techniques for analyzing network traffic. If efficient analysis tools were available, it could become possible to detect the attacks, anomalies and to appropriately take action to contain the attacks before they(More)

In comparison with prior work on high-speed congestion control, the paper explores an interesting design space: what if(More)
Considerable work has been done in devising mechanisms for providing service guarantees within a network. These schemes can be broadly classiied into two categories, schemes that require maintaining state for each ow and schemes that do not require maintaining state for each ow within the network. Both the approaches have their advantages and proponents.(More)
This paper discusses techniques for achieving desired throughput guarantees in the Internet that supports diierentiated services framework. Dii-serv framework proposes using diierent drop precedences to achieve soft service guarantees over Internet. However, it has been observed that the drop precedences by themselves cannot achieve the desired target rates(More)
This paper presents the implementation and evaluation of an active storage system. Our prototype system is based on the multi-view storage system (MVSS). It uses the notion of views to support " filtering " of data at the storage devices. Similar to views of a database in a multi-view database system, views in our system are generated dynamically and are(More)
— In this paper we investigate the impact of packet reordering on the performance of high-speed protocols. Our results show that even small fraction of packet reordering can severely impair the performance of these protocols. We then investigate the benefits of using delayed congestion response (TCP-DCR) with the high-speed protocols. Our results indicate(More)
