MESSAGE FORWARDING IN DATA CENTER NETWORK

摘要

A data center network comprises CORE devices which are stacked to form a stack system and an ACCESS device. Information of connection between each CORE device in the stack system and its peer ACCESS devices is recorded. Upon determining a change in the information of connection between any CORE device and its peer ACCESS devices, said CORE device is labeled with a low-forwarding-capability identifier. When transmitting a message, the ACCESS device selects a CORE device other than the CORE device labeled with a low-forwarding-capability identifier to perform the message forwarding.

1. A message forwarding method in a data center network, said data center network comprising CORE devices and ACCESS devices, wherein the CORE devices form a stack system through stacking, wherein said method comprises:
recording information of connection between each CORE device in the stack system and its peer ACCESS devices; upon determining a change in the information of connection between any CORE device and its peer ACCESS devices, labeling said CORE device with a low-forwarding-capability identifier and controlling any ACCESS device, when transmitting a message, to select a CORE device other than said CORE device labeled with a low-forwarding-capability identifier to perform message forwarding.
