Data Processing System with Routing Tables

摘要

A data processing system with routing tables comprising an operating system for supporting processes, such that the process are associated with one or more resources and the operating system being arranged to police the accessing by processes of resources so as to inhibit a process from accessing resources with which it is not associated. Part of this system is an interface for interfacing between each process and the operating system and a memory for storing state information for at least one process. The interface may be arranged to analyze instructions from the processes to the operating system, and upon detecting an instruction to re-initialize a process cause state information corresponding to that pre-existing state information to be stored in the memory as state information for the re-initialized process and to be associated with the resource.

1. A data processing system comprising:
an operating system that stores a plurality of first network routing tables each comprising one or more entries, each entry indicating at least part of a route over a network to a respective destination; at the user level a copy of the respective first network routing table; and a network data transmission function arranged to transmit data in accordance with the copy network routing table and without accessing the first network routing table.
