Heterogeneous IP Networks (HIPNet)

This project is in collaboration with Ericsson, Freescale (formerly Motorola Semiconductors), Artesyn (a software company), University of Wales Swansea, University of Cambridge, University of Essex and Aston University. The project has a telematics strand where future telematics networks and wireless systems are modeled and validated. This is part of a collaborative research project, funded by the Technology Strategy Board (TSB) (formerly Department of Trade and Industry (DTI)) and EPSRC (Engineering & Physical Science Research Council).

Goals of the project

  • Characterise and model multi service networks including mobile, fixed, edge (including telematics based networks) and core
  • Validate Next Generation Networks (NGN) behavioural model and impact of new services on this modelling
  • Validate advanced technology and impact of any associated new services
  • Develop an advanced and proven design capability allowing the design of reliable, cost effective networks


Information & Communication Technogolies (ICT) is a substantial part of the UK's GDP and is of vital importance to the UK economy. Since 2000 the UK has made substantial progress in creating one of the most competitive broadband markets in the world and is seeing 3G mobile starting to make a real impact on services. All this is leading towards the UK being a digitally rich economy, with ICT becoming all-pervasive in our lives.

The HIPNet project supports the UK in maintaining this technological lead by providing knowledge and skills in the validation and verification of these complex ICT networks through a combination of experimental development and modelling. HIPNet will focus on traffic modelling and the network testing of techniques needed to economically achieve the required levels of Quality of Service (QoS) for multiple services, in Next Generation Networks (NGNs), under conditions of traffic growth and also of major disruption. This activity is set against the background of a step change in network features which is driving this additional complexity.

A test-bed that contains all the constituent network components of a NGN is to be developed to validate end to end service delivery. In addition it is important to be able to predict the behaviour of complex networks and develop rules to ensure that the networks being built can be scaled to meet the needs of new and evolving services. This aspect of the network validation can be performed by a number of modelling activities, which can then be verified by comparison with the results from the network test-beds.
