TRAMMS (see text box), is a Celtic project coordinated by Acreo, which focuses on measuring and modelling IP traffic in access networks.
The project has been running 2007 – 2009. In April 2010 a seminar is held to disseminate the results.

This involves detailed knowledge of applications used by broadband customers in different parts of Europe, and the demands that they put on the networks. For this purpose, traffic measurements on the application level are performed in selected access networks in Sweden and Spain, and will possibly be performed in other countries in the near future.
Measurements show that the traffic from peer-to-peer (p2p) file sharing completely dominates the Internet, with a share of over 90 % of the total traffic (measured in a Swedish municipal network, with fiber access customers). Earlier measurements from the Acreo National Testbed have shown that the p2p applications also have a large penetration; over 80 per cent of the households have used p2p applications (during a three-month measurement period). Although the usage of these applications is widely spread among the households, there are some heavy users that dominate the bandwidth. In the same measurement, 10 per cent of the households generated 2/3 of the traffic volume.
There is a large interest in these activities and some of the reasons for this are
- the rapid change in Internet user behaviour since new services emerge and become popular very quickly
- that these applications are accessed from many different terminals (PC, cell phone, etc.) and through different types of networks (LAN, wifi, 3G, HSDPA), and this adds new requirements to the networks, since they must be able to support the new emerging applications.
It is therefore natural that these areas of interest are two of the main focus areas for the Acreo research in the field. Understanding the trends in IP application usage and the implications that they have on the networks is imperative in order to plan and deploy IP multi-service networks. This work is partly performed in the framework of the TRAMMS project, where experts from 12 organisations in the field get together and analyse results from Swedish and other networks in Europe.
The main goal of the TRAMMS project is to characterise the traffic generated by end-users in fixed access network infrastructures by specifying traffic parameters to be measured and analysed in the different test sites, and to jointly evaluate the results and develop traffic models built upon them. Based on the traffic models, dimensioning rules for capacity planning of IP networks will be created. To achieve the goals of TRAMMS, work will be performed in the following main areas:
- Traffic measurements in fixed metro/access networks.
- Traffic analysis and models for fixed metro/access networks.
- Broadband bottleneck analysis and capacity planning
- Monitoring of routing events and QoS parameters
