High-end routers and switches perform performance-critical lookupsinto large data based on network packet content. Current designs relyon specialized hardware modules for high performance. While mostlysufficient, emerging new protocols create a problem; for these to bedeployed, expensive equipment upgrades are required. To support the rapid deployment of new data plane protocols, we need a flexible hardware/software framework.This project is developing such a unified framework for futurenetwork devices with four components: a) an abstract execution modelto represent hardware, b) a toolchain to ease implementation, d)quantitative performance evaluation of protocols, and d) programmablehardware architectures specialized for the core operations in networkprotocols. Leveraging trends in tiled architectures, the project isdeveloping a specialized tiled architecture that moves computation closeto storage and thus provide efficient lookups. The project is alsoinvestigating how these design methodologies extend beyond protocolprocessing to payload inspection as required by intrusion prevention,application identification and other functionality.Deploying and implementing new protocols is challenging. This projectwill result in specification of flexible hardware for high-endrouters. This flexibility to support multiple protocols using a singletoolchain and architecture framework will reduce development costs offuture high-end routers and speedup the deployment of newprotocols. Another outcome will be the open-source release tothe academic community of the toolchain for developing high-speedimplementation of protocols, reference implementations of variousprotocols, standard data sets, and a NetFPGA implementation of theproposed hardware architecture.

高端路由器和交换机根据网络数据包内容对大量数据执行性能关键型查找。 目前的设计依赖于专门的硬件模块来实现高性能。虽然基本上已经足够了，但新兴的新协议会带来一个问题;要部署这些协议，需要昂贵的设备升级。为了支持新的数据平面协议的快速部署，我们需要一个灵活的硬件/软件框架，本项目正在为未来的网络设备开发这样一个统一的框架，该框架由四个部分组成：a）一个抽象的执行模型来表示硬件，B）一个工具链来简化实现，d）协议的定量性能评估，以及d）专门用于网络协议核心操作的可编程硬件架构。利用平铺架构的趋势，该项目正在开发一种专门的平铺架构，将计算移动到存储附近，从而提供高效的查找。该项目还调查了这些设计方法如何从协议处理扩展到入侵防御、应用程序识别和其他功能所需的有效负载检查。部署和实施新协议具有挑战性。这一项目的结果是为高端路由器提供灵活的硬件规范。这种使用单一工具链和架构框架支持多种协议的灵活性将降低未来高端路由器的开发成本，并加快新协议的部署。另一个成果将是向学术界开源发布工具链，用于开发高速协议实现、各种协议的参考实现、标准数据集以及拟议硬件架构的NetFPGA实现。
