“…Lakshman and Madhow [18] MAWI provides data from 1999 onwards on a Japanese network connecting universities and research institutes http://mawi.wide.ad.jp/. The data consist of the traffic captured for 15 minutes every day and has been used for long-term data analysis [19]. To get a sample which spans a long time period, in this paper data are sampled from the 15th day of every month from October 2006 to December 2012.…”

Abstract-This paper considers fundamental measurements which drive TCP flows: throughput, RTT and loss. It is clear that throughput is, in some sense, a function of both RTT and loss. In their seminal paper Padyhe et al [1] begin with a mathematical model of the TCP sliding window evolution process and come up with an equation showing that TCP throughput is (roughly) proportional to 1/RT T √ p where p is the probability of packet loss. Their equation is shown to be consistent with data gathered on several links. This paper takes the opposite approach and analyses a large number of packet traces from well-known sources in order to create a data-driven estimate of the functions which relate TCP, loss and RTT. Regression analysis is used to fit models to connect the quantities. The fitted models show different behaviour from that expected in [1].

“…Self-similarity is important because it may affect the buffer sizes in switches and the probability of collisions on Ethernet networks [354] -both of which affect the ability to achieve a given quality of service and satisfy service-level agreements. More recent data shows that self-similarity is retained when the traffic scales up in gigabit networks, and even under congestion [82].…”

Reliable performance evaluations require the use of representative workloads. This is no easy task since modern computer systems and their workloads are complex, with many interrelated attributes and complicated structures. Experts often use sophisticated mathematics to analyze and describe workload models, making these models difficult for practitioners to grasp. This book aims to close this gap by emphasizing the intuition and the reasoning behind the definitions and derivations related to the workload models. It provides numerous examples from real production systems, with hundreds of graphs. Using this book, readers will be able to analyze collected workload data and clean it if necessary, derive statistical models that include skewed marginal distributions and correlations, and consider the need for generative models and feedback from the system. The descriptive statistics techniques covered are also useful for other domains.

Passive and Active Measurement

Abstract. Internet speed at the edge is increasing fast with the spread of fiberbased broadband technology. The appearance of bandwidth-consuming applications, such as peer-to-peer file sharing and video streaming, has made traffic growth a serious concern like never before. Network operators fear congestion at their links and try to keep them underutilized while no concrete report exists about performance degradation at highly utilized links until today. In this paper, we reveal the degree of performance degradation at a 100% utilized link using the packet-level traces collected at our campus network link. The link has been fully utilized during the peak hours for more than three years. We have found that per-flow loss rate at our border router is surprisingly low, but 30 ∼ 50 msec delay is added. The increase in delay results in overall RTT increase and degrades user satisfaction for domestic web flows. Comparison of two busy traces shows that the same 100% utilization can result in different amount of performance loss according to the traffic conditions. This paper stands as a good reference to the network administrators facing future congestion in their networks.
