HIPNet / Heterogeneous IP Networks

信息和通信技术对英国经济至关重要。在过去的5年里，英国在打造世界上最具竞争力的宽带市场方面取得了实质性进展，3G移动开始对服务产生真正的影响。所有这些都导致英国成为一个数字富裕的经济体，ICT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的方式对这些复杂的信息和通信技术网络进行验证和验证，从而支持英国保持这一技术领先地位。它将重点放在流量建模和网络测试所需的技术上，以便在流量增长和重大中断的条件下，在下一代网络(NGN)中为多种不同的服务经济地实现所需的服务质量(QoS)水平。这项活动是在网络特征逐步变化的背景下进行的，这一变化正在推动这一额外的复杂性。将开发一个包含NGN的所有组成网络组件的试验台，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进行扩展，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多个建模活动来执行，这些建模活动然后可以通过与来自网络测试台的结果进行比较来验证

ICT 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 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 and diverse 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
