METHODS OF PROVIDING ACCESS TO I/O DEVICES
First Claim
1. A method of providing one or more computing devices with access to a plurality of resources, the plurality of resources being provided by at least one physical device, the method comprising, at a first control element:
- receiving a data packet transmitted by one of said one or more computing devices;
determining whether said data packet comprises a command including a first logical identifier identifying one of said resources; and
if it is determined that said data packet comprises a command including a first logical identifier;
obtaining a second logical identifier, the second logical identifier being associated with said first logical identifier and identifying said one of said resources; and
transmitting a request including said second logical identifier to a second control element, the second control element being arranged to identify a physical device associated with said second logical identifier and to forward said request to the identified physical device.

Abstract
A method of providing one or more computing devices with access to a plurality of resources. The plurality of resources are provided by at least one physical device. The method comprises, at a first control element receiving a data packet transmitted by one of said one or more computing devices, and determining whether said data packet comprises a command including a first logical identifier identifying one of said resources. If it is determined that said data packet comprises a command including a first logical identifier a second logical identifier is obtained, the second logical identifier being associated with said first logical identifier and identifying said one of said resources. A request including said second logical identifier is transmitted to a second control element, the second control element being arranged to identify a physical device associated with said second logical identifier and to forward said request to the identified physical device.

28. A control element for providing one or more computing devices with access to a plurality of resources, the plurality of resources being provided by at least one physical device, the apparatus comprising:
-
an interface arranged to receive a data packet transmitted by one of said one or more computing devices; a processor arranged to determine whether said data packet comprises a command including a first logical identifier identifying one of said resources, wherein if it is determined that said data packet comprises a command including a first logical identifier;
the processor is arranged to obtain a second logical identifier, the second logical identifier being associated with said first logical identifier and identifying said one of said resources;an interface arranged to transmit a request including said second logical identifier to a further control element if it is determined that said data packet comprises a command including a first logical identifier identifying one of said resources, the further control element being arranged to identify a physical device associated with said second logical identifier and to forward said request to the identified physical device. - View Dependent Claims (29, 30, 31, 32, 33)
