随着弹性云架构和移动计算系统的使用增加，对基于软件的网络的附加层的需求也随之增加。研究界已经提出了开放标准来指定网络服务，而不将规范与网络接口相耦合，称为软件定义网络(SDN)。这样的软件层可以提高网络路由器和交换机的性能。随着网络安全需求的增加，包括高性能计算在内的各种应用的流量聚合将进一步要求数据平面的新解决方案。本项目探索基于硬件和软件的解决方案，以在延迟、吞吐量和功率效率方面优化SDN数据平面。这项工作研究了新的算法、数据结构和架构，这些算法、数据结构和架构利用了最先进的技术，包括异构型多处理器系统芯片架构、多核处理器和可编程门阵列，以实现灵活的数据平面内核设计并了解性能权衡。将开发基于散列和数据结构的大规模IP查找的新解决方案，以及支持高性能的多字段包分类的并行解决方案。这项工作还开发了使用混合树和虚拟引擎的网络虚拟化和数据聚合的新技术，以在各种平台上实现高性能。该项目的更广泛影响包括为高性能互联网主干提供灵活且可扩展的解决方案，以支持下一代网络。

As the use of elastic cloud architectures and mobile computing systems increases, the need for an additional layer of software based networking arises. The research community has proposed open standards to specify network services without coupling specifications with network interfaces, referred to as Software Defined Networking (SDN). Such a software layer can improve the performance of network routers and switches. As demands due to network security increase, aggregation of traffic from diverse applications including high performance computing will further require novel solutions for the data plane.This project explores hardware as well as software-based solutions to optimize the SDN data plane with respect to latency, throughput, and power efficiency. The work investigates novel algorithms, data structures, and architectures that exploit state-of-the-art technologies including heterogeneous multi-processor system-on-chip architectures, multi/many-core processors, and Programmable Gate Arrays to realize flexible designs for data plane kernels and understand performance tradeoffs. Novel solutions based on hashing and data structures for large-scale IP lookup as well as parallel solutions for multi-field packet classification to support high performance will be developed. The work also develops new techniques for network virtualization and data aggregation using hybrid trees and virtual engines to achieve high performance on various platforms. The broader impact of the project includes providing a flexible and scalable solution for a high performance Internet backbone to support next generation networking.
