ABSTRACT:
An architecture that achieves high speed performance in a network protocol handler combines parallelism and pipelining in multiple programmable processors, along with specialized front-end logic at the network interface that handles time critical protocol operations. The multiple processors are interconnected via high-speed interconnect, and each processor's memory is globally accessible by other processors. Each processor has multiple threads, each capable of fully executing programs. Each processors contains embedded dynamic random access memory (DRAM). Threads within a processor are assigned the processing of various protocol functions in a parallel/pipelined fashion. Data frame processing is done by one or more of the threads to identify relates frames. Related frames are dispatch to the same thread so as to minimize the overhead associated with memory accesses and general protocol processing. The high-speed protocol handler may also provide built-in monitors for examining the activity of its hardware resources and reallocating the workload to the resources that are not heavily used, thus balancing the resource utilization and increasing the workload throughput.
