Network Sort Engine Based on Concurrent Heap -- Toward Implementing Massive and Ultra High Speed Per-flow Queuing --
Muneyoshi Suzuki, Katsuya Minami (NTT) IN2006-77
Abstract (in Japanese) (See Japanese page) 
(in English) Network Sort Engine (NSE) that rapidly identifies the highest priority from numerous priorities is indispensable to enable per-flow queuing that supports massive queues and high speed communication line. This is because bottleneck of per-flow queuing is the selection process of a single queue to emit a frame from queues which are ready to emit frame; this process leads a sorting issue which identifies the highest priority. Thus, concurrent heap that parallelizes each layers of a binary tree is invented for an implementation method of massive and ultra high speed NSE. It does not essentially modify conventional heap algorithm which can work at high speed due to lightweight memory management and ensure worst case run time. FPGA implementation results of concurrent heap indicates that required resources are very small thus it could practically be implemented in a small FPGA, and measured run time speed shows that thousands per-flow queuing for 10GbE LAN-PHY could work at wire-rate with successive of minimum length frames.
