Sampling TCP Data-Path Quality with TCP Data Probes
نویسندگان
چکیده
In this paper, we present preliminary results of measuring TCP data-path quality using a new measurement tool called OneProbe. Unlike the existing tools, OneProbe uses legitimate TCP data probes to profile TCP data-path quality by sampling round-trip delay, one-way loss rate, and one-way reordering rate at the same time. This paper presents a set of recent measurement studies on a set of web servers hosting the Beijing Olympic Games in China and Hong Kong.

Evaluating Multipath TCP Resilience against Link Failures
Standard TCP is the de facto reliable transfer protocol for the Internet. It is designed to establish a reliable connection using only a single network interface. However, standard TCP with single interfacing performs poorly due to intermittent node connectivity. This requires the re-establishment of connections as the IP addresses change. Multi-path TCP (MPTCP) has emerged to utilize multiple ...
متن کاملLinkWidth: A Method to measure Link Capacity and Available Bandwidth using Single-End Probes
We introduce LinkWidth, a method for estimating capacity and available bandwidth using single-end controlled TCP packet probes. To estimate capacity, we generate a train of TCP RST packets “sandwiched” between two TCP SYN packets. Capacity is obtained by end-to-end packet dispersion of the received TCP RST/ACK packets corresponding to the TCP SYN packets. Our technique is significantly differen...
متن کاملTo maximize throughput via multi-pathing and Parallel TCP on each path
Parallel TCP, which opens multiple TCP connections over a single path, and Multi-Pathing, which concurrently uses multiple paths to transfer data, have both been proved to be effective methods to improve end-to-end throughput. How much throughput can we ultimately achieve between a source and a destination if we use multiple overlay paths and open multiple TCP connections on each used path? In ...

متن کاملDesign and Implementation of TCP Data Probes for Reliable and Metric-Rich Network Path Monitoring
Monitoring network services and diagnosing their problems often require active probing methods. Current probing methods, however, are becoming unreliable, because of interferences from various middleboxes, and inadequate due to their limited path metrics support. In this paper, we present the design and implementation of OneProbe, a new TCP probing method for reliable and metric-rich path monit...
