Addressing a workload partition

摘要

A method for addressing a workload partition is provided in the illustrative embodiments. A packet of data directed to the WPAR and including a combined address is received at a software stack. A determination is made whether the combined address includes an identifier that is reserved. If the identifier is not reserved, the identifier is used to identify the WPAR in the data processing system and the packet is sent to the WPAR. The software stack is an application configured to enable data communication using a protocol of the packet, and is modified to detect, recognize, and process the combined address for routing the packet to the WPAR. The combined address may be logically formed using an identifier associated with the data processing system and an identifier associated with the WPAR, which may be located in different portions of the packet.

主权项

1. A computer implemented method for addressing a workload partition (WPAR), the computer implemented method comprising:
receiving, from a second data processing system, a packet of data at a software stack executing in a data processing system, the packet being directed to the WPAR executing in the data processing system, the packet including a combined address, wherein the combined address combines a first part to identify the data processing system to the second data processing system over a data network and a second part to identify the WPAR executing in the data processing system, wherein the first part and the second part are separated in the combined address using a delimiter character; determining whether the combined address includes an identifier that is reserved, wherein when a predetermined function is to be performed at the data processing system, the combined address in the packet stores the identifier that is reserved, the identifier corresponding to the function; using the identifier to identify the WPAR in the data processing system when the identifier is not reserved; and sending the packet to the WPAR.
