SIMET  (Traffic Measurement System) - http://simet.nic.br/ which consists of a webpage with a Java applet and servers inside our Internet Exchange Points. The Java applet can measure delay, jitter, TCP and UDP bandwidth, among other network parameters. There are a lot of such tests spread over the Internet, but ours has two important characteristics that bring some advantages. First: the majority of Brazilian Internet providers exchange traffic directly with the network in which SIMET servers are; it is almost the same as to have the test servers inside the provider network, the results are not distorted by foreign networks. Second: alongside with giving the end user the knowledge about the quality of his connection, we collect the data, and it becomes an important tool for the Brazilian Internet Steering Comittee to know the general quality of our national Internet Providers.
