Background TCP data transfer with Inline network measurement

Abstract

Abstract-In the present paper, ImTCP-bg, a new background TCP data transfer mechanism that uses an inline network measurement technique, is proposed. ImTCP-bg sets the upper limit of the congestion window size of the sender TCP based on the results of the inline network measurement, which measures the available bandwidth of the network path between the sender and receiver hosts. ImTCP-bg can provide background data transfer without affecting the foreground traffic, whereas previous methods cannot avoid network congestion essentially. ImTCP-bg also employs an enhanced RTT-based mechanism so that ImTCP-bg can detect and resolve network congestion, even when reliable measurement results cannot be obtained. The performance of ImTCP-bg is investigated through simulation experiments, and the effectiveness of ImTCP-bg in terms of the degree of interference with foreground traffic and the link bandwidth utilization is also investigated.

Aggregate Congestion Control for Peer-to-Peer File Sharing Applications

“…4CP [10] adjusts its cwnd through balancing the loss probability along a network path to some target of loss probability with farsighted strategy. ImTCP-bg [11] uses an inline network measurement technique [12] which uses modified TCP protocol to measure the network available bandwidth. Based on measured available bandwidth, ImTCP-bg adjusts the rate of data packets transfer.…”

“…ImTCP-bg [61] is a delay-based scheme close in spirit to TCPW-LP. A congestion control algorithm, based on estimating the available bandwidth, is complemented with a congestion detector based on RTTs.…”

Design, Implementation and Evaluation of ICMP-Based Available Network Bandwidth Measurement Based on IMTCP

“…When multiple peers hold the same resource in a P2P network, we can use network bandwidth information to choose a peer to retrieve the resource from. In a CDN, we can transfer data at low priority on the basis of bandwidth information so as not to affect high priority data transfer [5]. Network bandwidth information can also be used for the determination of the failure point in a network.…”
