NEDG: Application Oriented Edge Routers

该项目重新审视了边缘路由器的角色，并开发了新的架构，从而设计了面向应用程序的边缘路由器。该路由器高度智能化。并通过将数据包移动到应用层来提供高级网络服务。此类应用程序（服务）的示例包括安全和用户保护、定价、负载平衡、多媒体、点对点（P2P）和VoIP。新颖性和技术优点：a.应用感知处理。开发了多线程算法和多核调度技术，以提高吞吐量和减少延迟，同时保持应用程序的QoS要求。通过网络处理器实现。应用程序处理通过可编程网络处理器（NPs）也进行了探讨。为了满足不同业务的需求，开发了新的NP分区、处理器分配和调度方案。服务分类。对基于签名的包分类技术进行了扩展，根据需要的业务区分入方向的流量。更广泛的影响：a.产业影响和技术转移：目前来自Cisco和Intel的项目与项目有互补效应和协同互动。b.国际合作：刘斌教授的积极参与，促成了UCR与清华大学的长期合作。c.教育影响：项目的基准应用和成果得到广泛传播。该项目还培养了高质量的博士研究生，包括加州大学洛杉矶分校的本科生。d.少数民族外展计划：UCR本科生中有30-40%是少数民族学生。因此，这个项目对加州大学洛杉矶分校的外联活动产生了扩大和直接的影响。

This project revisits the role of the edge router, and develops novel architectures that lead to the design of an Application Oriented Edge Router. The router is highly ?intelligent? and provides advanced network services by moving packets to the application layer. Examples of such applications (services) are security and user protection, pricing, load balancing, multimedia, peer-to-peer (P2P) and VoIP.Novelty and Technical Merit: a. Application aware processing. Multithread algorithms and multi-core scheduling techniques are developed so as to increase throughput and reduce latency while preserving the QoS requirement of an application.b. Implementing through network processors. Application processing through programmable network processors (NPs) is also explored. New NP partitioning, processor allocation and scheduling schemes are developed to meet the requirements of various services.c. Service classification. The signature based packet classification techniques are extended to differentiate the incoming traffic based on required services. Broader impact: a. Industrial impact and technology transfer: The current projects from Cisco and Intel have complimentary effect and synergistic interaction with project. b. International collaboration: The active participation of Prof. Bin Liu in the project brings in long-term collaboration between UCR and Tsinghua University. c. Educational impact: Benchmark applications and results from the project are widely disseminated. The project also produces high quality Ph.D. graduates and involves Undergraduate students at UCR. d. Minority outreach plan: 30-40% of the UCR undergraduate body is minority students. As a result, this project has an amplified and direct impact on the outreach activities at UCR.
