....of switch resources. PIGLET While the SANE architecture presents a secure resource management interface to switchlets, the underlying system must be capable of providing the appropriate capabilities to implement that interface. In the SQoSH architecture those capabilities are provided by Piglet [8], a multiprocessor operating system designed to provide applications with low overhead direct access to network resources. PIGLET: STRUCTURE AND ARCHITECTURE The Piglet architecture is based around the concept of an active kernel one or more system CPUs are dedicated to continually running ....

....the two tests was the mechanism used to send packets, any differences in roundtrip time can be attributed to the overhead of those mechanisms. Table 1 shows the modal round trip time measured for various sizes of packets; a more detailed histogram and analysis of these results is presented in [8]. These figures show that the difference in round trip time, or equivalently the difference in the overhead of sending a packet, varies from 38 s to 55 s, there being some dependence on payload size due to Piglet performing less data copying than Linux. We believe that such a reduction, due to ....
