INFORMATION PROCESSING SYSTEM, SWITCHING DEVICE, AND METHOD FOR CONTROLLING INFORMATION PROCESSING SYSTEM |
摘要 |
An information processing system includes a switching device group including a plurality of switching devices that include a switching device as a root node and switching devices as leaf nodes and are connected in a tree topology. The switching device includes: a controller that, when a failure that occurs in a communication path connected to the root node side of the switching device is detected, writes identification information indicating the communication path from which the failure is detected to a flow table which stores the identification information and output destination port information so as to be associated with each other, thereby switching a plurality of communication paths; and a notification unit that, when a failure that occurs in a communication path connected to the leaf node side of the switching device is detected, notifies another switching device connected to the switching device of a position where the failure occurs. |

1. An information processing system comprising:
a switching device group including a plurality of switching devices that include a switching device as a root node and switching devices as leaf nodes which are connected to an information processing apparatus, the plurality of switching devices being connected in a tree topology, wherein the switching device includes: a controller that, when a failure that occurs in a communication path connected to the root node side of the switching device is detected, writes identification information indicating the communication path from which the failure is detected to a flow table which stores the identification information and output destination port information indicating a communication path of an output destination of a packet so as to be associated with each other, thereby switching a plurality of communication paths; and a notification unit that, when a failure that occurs in a communication path connected to the leaf node side of the switching device is detected, notifies another switching device connected to the switching device of a position where the failure occurs. |
