Abstract
An Island-Based Network Flow Processor (IB-NFP) receives packets of many flows, and classifies them as belonging to an ordering context. These packets are distributed to a set of Worker Processors (WPs), so that each packet of the context is processed by one WP, but multiple WPs operate on packets of the context at a given time. The WPs use an atomic ticket release functionality of a transactional memory to assist in determining when to release packets to another set of Output Processors (OP). The packets are indicated to the set of OPs in the correct order, even though the WPs may complete their processing of the packets in an out-of-order fashion. For a packet that is indicated as to be released, an OP generates a 'transmit command' such that the packet (or a descriptor of the packet) is then put into a properly ordered stream for output from the IB-NFP.
