Two forces have exacerbated problems associated with packet processing. First, demands for higher bandwidth and line rates challenge our abilities to perform real-time packet processing. Second, more complex functional requirements and services are being defined that significantly increase packet computational demand. In response, modern routers are being equipped with Network Processors (NPs) that include both general-purpose multiprocessing and special hardware capabilities. NPs push the envelope of our design capabilities. This research aims at quantifying NP design and at developing a performance driven methodology that is cognizant of both physical constraints (e.g., area, power) and the computational requirements of packet applications.Principal architectural approaches (parallelism, pipelining, instruction specialization) are investigated and design procedures for exploiting these architectural paradigms are developed. The NP architecture models along with associated benchmarking lead to a coherent NP design methodology and extend our understanding of real-time computer design.The research directly benefits the rapidly expanding area of NP and router design, and network performance. The techniques utilized are those of classical computer architecture, including the formalization of the design constraints, development of design models, and the use of benchmarks for quantitative model parameterization.

两种力量加剧了与分组处理相关联的问题。首先，对更高带宽和线路速率的需求挑战了我们执行实时数据包处理的能力。其次，更复杂的功能需求和服务正在被定义，这显著增加了分组计算需求。作为回应，现代路由器配备了网络处理器（NP），包括通用多处理和特殊硬件功能。纳米粒子推动了我们设计能力的极限。本研究旨在量化NP设计，并开发一种性能驱动的方法，该方法认识到物理约束（例如，面积，功率）和包应用程序的计算要求。主要的架构方法（并行，流水线，指令专门化）进行了研究，并开发了利用这些架构范例的设计程序。NP体系结构模型沿着相关的基准测试，形成了一个连贯的NP设计方法，扩展了我们对实时计算机设计的理解，对迅速扩展的NP和路由器设计领域以及网络性能有着直接的益处。所采用的技术是经典的计算机体系结构，包括形式化的设计约束，开发的设计模型，并使用定量模型参数化的基准。
