Abstract
A software virtual machine mechanism that increases the efficiency of context switching is disclosed. In an application to the networking environment, the software virtual machine is operative to increase the efficiency of handling input/output operations through the improved control of switching between contexts. The software virtual machine supports restartable instructions such that the resumption of a previously blocked context will continue at the instruction that had previously blocked.
