HIPNet / Heterogeneous IP Networks

ICT是英国GDP的重要组成部分，对英国经济至关重要。在过去的5年里，英国在创造世界上最具竞争力的宽带市场方面取得了实质性的进展，并且看到3G移动的开始对服务产生真实的影响。所有这一切都导致英国成为一个数字丰富的经济体，信息通信技术在我们的生活中无处不在。HIPNet项目支持联合王国保持这一技术领先地位，通过实验开发和建模相结合的方式，为这些复杂的信息和通信技术网络的验证和核查提供知识和技能。它将侧重于流量建模和网络测试所需的技术，以经济地实现所需的服务质量（QoS）水平的多种服务，在下一代网络（NGN），在流量增长的条件下，也是重大的中断。这一活动是在网络功能发生阶跃变化的背景下进行的，这种变化导致了这种额外的复杂性。将开发一个包含NGN所有组成网络组件的测试床，以验证端到端服务交付。此外，重要的是能够预测复杂网络的行为，并制定规则，以确保正在建设的网络可以扩展，以满足新的和不断发展的服务的需求。网络验证的这一方面可以通过许多建模活动来执行，然后可以通过与网络测试台的结果进行比较来验证

ICT is a substantial part of the UK's GDP and is of vital importance to the UK economy. In the past 5 years 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. It 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 is 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
