Abstract
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.
Claims9
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.
A CORE device for use in a data center network, said CORE device being capable of forming a stack system together with other CORE devices, wherein said CORE device comprises:
- a recording unit to record information of connection between said CORE device and its peer ACCESS devices;
- a controlling unit to label said CORE device with a low-forwarding-capability identifier upon determining a change in the information of connection between said CORE device and its peer ACCESS devices, and control 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.
An ACCESS device for use in a data center network which comprises CORE devices which are stacked together to form a stack system through stacking, said ACCESS device comprising:
- a selecting unit to select a CORE device from other CORE devices than the CORE device labeled with a low-forwarding-capability identifier when transmitting a message, wherein a CORE device is labeled with a low-forwarding-capability identifier when determining a change in the information of connection between the CORE device and its peer ACCESS devices;
- a transmitting unit to forward a message to the selected CORE device.
