Data transfer

A non-transitory computer-readable medium storing computer-readable code for fabrication of an apparatus comprising:

• bridge circuitry configured to couple processing circuitry to an allocated subset of a plurality of port controllers for connecting the processing circuitry to link partners, wherein the bridge circuitry is configured to perform a data transfer between the processing circuitry and the allocated subset according to a bandwidth quota;
• and
• control circuitry configured to receive configuration information identifying the allocated subset, and to allocate a bandwidth share of the bandwidth quota to each port controller identified in the allocated subset,
• wherein the control circuitry is configured:
• to determine the bandwidth share that is allocated to each port controller based on the configuration information;
• and
• for each given port controller identified in the allocated subset, to implement a restriction to limit the data transfer between the given port controller and the processing circuitry according to the bandwidth share allocated to the given port controller.

A method comprising:

• coupling, with bridge circuitry, processing circuitry to an allocated subset of a plurality of port controllers for connecting the processing circuitry to link partners, wherein the bridge circuitry is configured to perform a data transfer between the processing circuitry and each port controller of the allocated subset according to a bandwidth quota;
• receiving configuration information identifying the allocated subset, and allocating a bandwidth share of the bandwidth quota to each port controller identified in the allocated subset, wherein the bandwidth share that is allocated to each port controller is determined based on the configuration information;
• and
• for each given port controller identified in the allocated subset, implementing a restriction to limit the data transfer between the given port controller and the processing circuitry according to the bandwidth share allocated to the given port controller.
