Control groups for network testing

摘要

Novel tools and techniques are provided for testing performance of network connections. In some cases, a method for testing performance of a network connection might comprise establishing a plurality of test points within one or more segments in the network connection. With a computer, performance of a selected segment of the network connection at one or more first test points may be tested. The selected segment might have a first endpoint and a second endpoint. The performance of one or more sub-segments of the selected segment at one or more second test points may also be tested with the computer. The computer may also determine an isolated performance of a particular one of the sub-segments based on the testing. In some instances, the method might further comprise determining, with the computer, that performance of the one or more sub-segments has affected performance of the network connection.

主权项

1. A method for testing performance of a network connection, the method comprising: identifying, at a computer, poor performance in browsing a web site on the Internet from a subscriber device at a subscriber premises, the subscriber premises comprising a subscriber local area network that provides communication between the subscriber device and a provider access network, the provider access network providing access, through an Internet drain, to the Internet; testing, with the computer, end-to-end network performance, by testing network performance between the subscriber device and the web site; testing, with the computer, a first segment network performance, by testing network performance between the subscriber device and a broadband modem on the subscriber local area network; testing, with the computer, a second segment network performance, by testing network performance between the broadband modem and the Internet drain; inferring, with the computer, a third segment network performance, by inferring network performance between the Internet drain and the web site, based on the tested end-to-end network performance, the tested first segment network performance, and the tested second segment network performance; and based on the testing of the end-to-end network performance, the first segment network performance, and the second segment network performance, and based on the inferring of the third segment network performance, wherein the third sub-segment network performance is not directly tested, determining, with the computer, a source of the poor performance, the source of the poor performance being one or more of the subscriber local area network, the provider access network, the Internet, or the web site.
