US 9,753,755 B2 · Addressing a workload partition

Abstract

A system, and computer usable program product for addressing a workload partition are 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.

Dependent claims

A computer usable program product comprising a computer usable storage device including computer usable code for addressing a workload partition (WPAR), the computer usable code comprising:

computer usable code for receiving, from a second data processing system, a packet of data at a software stack executing in a first data processing system, the packet being directed to the WPAR executing in the first data processing system, the packet including a combined address, wherein the combined address combines a first part to identify the first data processing system to the second data processing system over a data network and a second part to identify the WPAR executing in the first data processing system;
computer usable code for determining whether the combined address includes an identifier that is reserved;
computer usable code for using, responsive to the identifier not being reserved, the identifier to identify the WPAR in the first data processing system;
and
computer usable code for sending the packet to the WPAR.
