Nettimer: A Tool for Measuring Bottleneck Link Bandwidth

by Kevin Lai, Mary Baker - In Proceedings of the USENIX Symposium on Internet Technologies and Systems , 2001
"... Measuring the bottleneck link bandwidth along a path is important for understanding the performance of many Internet applications. Existing tools to measure bottleneck bandwidth are relatively slow, can only measure bandwidth in one direction, and/or actively send probe packets. We present the netti ..."

Measuring Link Bandwidths Using a Deterministic Model of Packet Delay

by Kevin Lai, Mary Baker - in Proceedings of ACM SIGCOMM , 2000
"... We describe a deterministic model of packet delay and use it to derive both the packet pair [2] property of FIFO-queueing networks and a new technique (packet tailgating) for actively measuring link bandwidths. Compared to previously known techniques, packet tailgating usually consumes less network ..."

Models for Non-intrusive Estimation of Wireless Link Bandwidth

by Jian Zhang, Liang Cheng, Ivan Marsic - in Proceedings of PWC , 2003
"... Dynamics of link bandwidth of a wireless link, which changes frequently and abruptly due to the dynamic channel sharing, fading, and mobility, is of interest to adaptive network applications and communication protocols. This paper presents a novel approach to estimate wireless link bandwidth bas ..."

Dynamic Partitioning of Link Bandwidth in IP/MPLS Networks

by Veselin Rakocevic , John M Griffiths , Graham Cope - in Proceedings in The IEEE International Conference on Communications (ICC’2001
"... Abstract: Bandwidth allocation in the future multiservice global communication IP network presents a very interesting research issue. This paper presents the strategy of Dynamic Partitioning of link bandwidth in IP network. In the Dynamic Partitioning scheme the bandwidth of each link in the networ ..."

Increasing Effective Link Bandwidth by Suppressing Replicated Data

by Jonathan Santos, David Wetherall, Jonathan Santos Y, David Wetherall Z , 1998
"... In the Internet today, transfer rates are often limited by the bandwidth of a bottleneck link rather than the computing power available at the ends of the links. To address this problem, we have utilized inexpensive commodity hardware to design a novel link layer caching and compression scheme that ..."

Congestion control for high bandwidth-delay product networks

by Dina Katabi, Mark Handley, Charlie Rohrs - SIGCOMM '02 , 2002
"... Theory and experiments show that as the per-flow product of bandwidth and latency increases, TCP becomes inefficient and prone to instability, regardless of the queuing scheme. This failing becomes increasingly important as the Internet evolves to incorporate very high-bandwidth optical links and mo ..."

Link-Sharing and Resource Management Models for Packet Networks

by Sally Floyd, Van Jacobson , 1995
"... This paper discusses the use of link-sharing mechanisms in packet networks and presents algorithms for hierarchical link-sharing. Hierarchical link-sharing allows multiple agencies, protocol families, or traflic types to share the bandwidth on a tink in a controlled fashion. Link-sharing and real-t ..."

The Performance of TCP/IP for Networks with High Bandwidth-Delay Products and Random Loss.

by Member, IEEE T V Lakshman , Senior Member, IEEE Upamanyu Madhow - IEEE/ACM Trans. Networking, , 1997
"... Abstract-This paper examines the performance of TCP/IP, the Internet data transport protocol, over wide-area networks (WANs) in which data traffic could coexist with real-time traffic such as voice and video. Specifically, we attempt to develop a basic understanding, using analysis and simulation, ..."

, of the properties of TCP/IP in a regime where: 1) the bandwidth-delay product of the network is high compared to the buffering in the network and 2) packets may incur random loss (e.g., due to transient congestion caused by fluctuations in real-time traffic, or wireless links in the path of the connection

Achieving Faster Access to Satellite Link Bandwidth

by unknown authors
"... TCP with Van Jacobson congestion control (VJCC) is known to have poor performance over large bandwidthdelay product paths. Long delay paths, in particular, can display very poor behavior with VJCC slowly probing to acquire available capacity. TCP Performance Enhancing Proxies (PEPs) constitute one m ..."
