Network Processors: Origin of Species
نویسندگان
چکیده
Numerous programmable alternatives to network processing have emerged in the past few years to meet the current and future needs of network equipment. They all promise various trade-offs between performance and flexibility. In this paper we attempt to understand these new network processing alternatives. We present five major aspects of network processor architectures: approaches to parallel processing, elements of specialpurpose hardware, structure of memory architectures, types of on-chip communication mechanisms, and use of peripherals. For each of these aspects, we include examples of specific network processor features.
