Beltway buffers are operating system I/O paths optimised for high-throughput network applications. The key architectural feature of Beltway buffers is that all I/O takes place in long-lived, allocation-free, shared ringbuffers. Advantages of this design are (1) improved throughput through system-wide copy, context-switch and allocation avoidance and judicious use of the data cache, (2) transparent integration of peripheral hardware and (3) simplicity and familiarity due to comprehensive use of… CONTINUE READING
