项目摘要

As demand for network capacity increases, the traditional practice of over-provisioning of the network becomes impractical. So, there is much ongoing work to define new protocols and mechanisms for high-speed, QoS-controlled networking within Internet Protocol (IP) based environments. This includes work on QoS mechanisms and services, congestion control mechanisms and work on new transport protocols for specific purposes. However, as these new mechanisms have been developing, there has not been much activity in trying to observe and analyse the behaviour of these systems working together, within a real, integrated networked environment. With the rapidly increasing deployment of IPv6, it is also vital to consider carefully the differences in behaviour in the use of these mechanisms compared to IPv4. In this project, we will have two broad areas of work. Firstly we will, through experimentation and analysis, examine how DIFFSERV, ECN and decentralised reservation can be made to operate together in a very highspeed IPv4 and IPv6 environment to support TCP- and UDP-based applications. Secondly, we will propose ways in which such networks can be instrumented in order to provide performance and operational data to network operators as well as users and applications through appropriate APIs and using network monitoring equipment via configurable sampling techniques, which will also be developed in the project. We will examine the performance of the system in a real networked environment operating at very high speeds (several Gb/s). To stretch the network services, we intend to test with selected applications from the e-Science/Grid community which have requirements for very high-speed connectivity and QoS-controlled network access. This proposal is supported by Sun Microsystems, Cisco Systems and UKERNA.

随着对网络容量的需求增加，传统的网络超额配置做法变得不切实际。因此，为基于互联网协议 (IP) 的环境中的高速、QoS 控制的网络定义新的协议和机制正在进行大量工作。这包括关于 QoS 机制和服务、拥塞控制机制的工作以及针对特定目的的新传输协议的工作。然而，随着这些新机制的不断发展，试图观察和分析这些系统在真实的集成网络环境中协同工作的行为的活动还很少。随着 IPv6 部署的迅速增加，仔细考虑这些机制与 IPv4 相比在使用方面的行为差异也至关重要。在这个项目中，我们将有两个广泛的工作领域。首先，我们将通过实验和分析，研究如何使 DIFFSERV、ECN 和去中心化预订在非常高速的 IPv4 和 IPv6 环境中一起运行，以支持基于 TCP 和 UDP 的应用程序。其次，我们将提出对此类网络进行检测的方法，以便通过适当的 API 并通过可配置的采样技术使用网络监控设备，向网络运营商以及用户和应用程序提供性能和操作数据，这些技术也将在项目。我们将检查系统在以非常高的速度（几 Gb/s）运行的真实网络环境中的性能。为了扩展网络服务，我们打算使用 e-Science/Grid 社区中选定的应用程序进行测试，这些应用程序需要非常高速的连接和 QoS 控制的网络访问。该提案得到了 Sun Microsystems、Cisco Systems 和 UKERNA 的支持。
