Abstract: A method for managing access to a physical resource in a data processing system supporting an application, the resource being identified by a physical address, and the method comprising: forming a token at an encryption entity by encrypting the physical address together with additional data, in such a way that decryption of the token yields decrypted data that includes the physical address and that can be used to verify the validity of the token; making the token available to the application; generating a command by means of the application for triggering accessing of the physical resource, the command including the token.

Abstract: Method for managing a queue in host memory for use with a peripheral device. Roughly described, the host makes a determination of the availability of space in the queue for writing new entries, in dependence upon historical knowledge of the number of queue entries that the host has authorized the device to write, and the number of entries that the host has consumed. In dependence on that determination, the host authorizes the device to write a limited number of new entries into the queue. The device writes entries into the queue dependence upon the number authorized. The host maintains a read pointer into the queue but does not need to maintain a write pointer, and the peripheral device maintains a write pointer into the queue but does not need to maintain a read pointer.

Abstract: Method of managing interaction between a host subsystem and a peripheral device. Roughly described, the peripheral device writes an event :finto an individual event queue, and in conjunction therewith, also writes a wakeup event into an intermediary event queue. The wakeup event identifies the individual event queue. The host subsystem, in response to retrieval of the wakeup event from the intermediary event queue, activates an individual event handler to consume events from the individual event queue.

Abstract: A network bridge (10) is provided for interfacing between a first network, such as a Gigabit Ethernet (11), having a first protocol and a second network, such as a CLAN (1-9) having a second different protocol. The network bridge (10) has a buffer (29) which receives payload data from Ethernet packets and a buffer (30) which supplies CLAN headers corresponding to the final destination address in memory to which an application for processing the payload data of the packet requires delivery. The CLAN packets are assembled at (31) so that the payload data are delivered to the final memory destination address without the need for a protocol stack in a computer of the CLAN cluster 5.
