Products

The project has impacted 7 product lines in 5 different companies. All of these products are aimed at finding the bottlenecks in the network and monitoring traffic and QoS parameters, and they complement each other in a very nice way to get a complete picture of the status of your network. The QoS related products include the CM-100, CompactSAE and SAE chassis from TELNET, the Accu-Qos from the recently formed startup Naudit. These products monitor QoS parameters by sending and analyzing probe packets. The BGP probe by GCM is a silent listener that can easily be installed near the border router to record and analyse BGP routing events. This information is collected and presented in a nice way to use for e.g. forensic activities for analysing routing events etc. BART (Bandwidth Available in Real Time) is an active method for estimating end-to-end available bandwidth and tight link capacity in real time over packet-switched network paths. As part of the TRAMMS project BART has been evaluated in realistic field tests, and further developed to improve accuracy in high speed networks. The knowledge gained in the project has been used to further develop and improve the PacketLogic product from Procera, mainly regarding its statistics functionality. Some of the products mentioned above are described in the project milestone M4.2.

Standardisation

Ericsson has within the project promoted standardization of active end-to-end capacity measurement methods in the International Telecommunication Union (ITU-T). The main result so far is the acceptance and inclusion of the IP-layer capacity framework in ITU-T Recommendation Y.1540. TRAMMS has contributed as a participant to the creation of the ISG MOI group under the ETSI framework.

Traffic analysis and measurements

Measurements from the application to the packet level per household were collected in real networks located in different countries (Sweden and Spain) covering different types of access (FTTH, xDSL, CMTS, GGSN, university network). Measurements from a large amount of users were gathered for long periods of time (close to 3000 TiB of traffic volume was analysed in Spanish and Swedish networks in 2007-2009 in periods ranging from several days to several years). A common methodology was established between the different partners in order to perform and share the measurements with other partners, as well as to prepare them for a later analysis, while preserving the user privacy and respecting the privacy policies of the operators.
