ABSTRACT
An extensive measurement capability has been implemented in the Interface Message Processors (IMP's) of the ARPA network of computers. These measurement facilities were implemented by the network contractor, Bolt Beranek and Newman, Inc., to meet the measurement needs of the UCLA Network Measurement Center, and consist of software routines within the store-and-forward IMP's to accumulate statistics, periodically record snap-shots, trace selected messages through the net, and to be able to generate artificial traffic. These capabilities have been augmented by routines at the Network Measurement Center to provide selective control over the data gathering functions, as well as, providing data reduction and print-out routines, and more extensive artificial traffic generation facilities. The purpose of the measurement effort is to provide insight into network behavior, and to support the analytic and simulation modeling work being done at UCLA. In this latter role, the measurements provide a means of verifying, or correcting, models of network behavior by performing appropriate tests in the actual network environment. The result of several such efforts will be discussed.

Crowdsourced network measurements
Network measurements are of high importance both for the operation of networks and for the design and evaluation of new management mechanisms. Therefore, several approaches exist for running network measurements, ranging from analyzing live traffic ...
Obtaining in-context measurements of cellular network performance
IMC '12: Proceedings of the 2012 Internet Measurement ConferenceNetwork service providers, and other parties, require an accurate understanding of the performance cellular networks deliver to users. In particular, they often seek a measure of the network performance users experience solely when they are interacting ...
Fundamental bounds on the accuracy of network performance measurements
SIGMETRICS '05: Proceedings of the 2005 ACM SIGMETRICS international conference on Measurement and modeling of computer systemsThis paper considers the basic problem of "how accurate can we make Internet performance measurements". The answer is somewhat counter-intuitive in that there are bounds on the accuracy of such measurements, no matter how many probes we can use in a ...
