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，英国在创建世界上最具竞争力的宽带市场之一方面取得了实质性的进展，并且看到3G移动开始对服务产生真正的影响。所有这些都使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变得无处不在。HIPNet项目通过实验开发和建模相结合，提供验证和验证这些复杂ICT网络的知识和技能，支持英国保持这一技术领先地位。它将专注于流量建模和网络测试所需的技术，以便在流量增长和重大中断的条件下，在下一代网络（ngn）中经济地实现多种服务所需的服务质量（QoS）水平。这一活动的背景是网络特性的逐步变化，这种变化导致了这种额外的复杂性。需要开发一个包含下一代网络所有组成网络组件的测试平台，以验证端到端业务交付。此外，重要的是能够预测复杂网络的行为并制定规则，以确保正在构建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试验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
