Abstract
A recoverable I/O request processor includes computer-executable instructions for processing I/O requests, such as requests to send or receive data through a network. The recoverable I/O request processor translates virtual memory addresses to physical memory addresses utilizing translation tables local to an I/O device. If a local translation fails, the recoverable I/O request processor requests virtual address mapping information from the operating system.
