<p>The invention provides a data processing network having a first processor, a second processor and a communication system linking said first processor and said second processor characterised in that when said first processor issues a call for triggering said second processor to allocate a real identifier for an entity, control logic associated with said first processor and responsive to said call from said first processor allocates a local identifier available for immediate use by said first processor and subsequently transforms between said local identifier and said real identifier. The invention both recognises and solves the problem of a first processor being delayed whilst waiting for an identifier to be supplied by a second processor. Control logic associated with the first processor provides a local identifier for use by the first processor without having to wait for the real identifier from the second processor. This mode of operation presents the problem that the first and second processors are using different identifiers for the same entity and so the control logic must also transform between the real and local identifiers in order to maintain integrity between the processors. The control logic is typically provided in the form of software running on the first processor.</p> |
