Abstract
A frame forwarding device for forwarding a frame in a network of a datalink layer includes: an acquisition unit for acquiring a status of an adjacent port from an adjacent device having the adjacent port accommodating a link accommodated in a port of a self-device; a determination unit for determining whether or not a frame loop is generated based on an inconsistency between a status of the port of the self-device and the status of the adjacent port; and a blocking unit for blocking the port of the self-device when determined that the loop is generated.

A frame forwarding device for forwarding a frame in a network of a datalink layer, comprising:
- an acquisition unit acquiring a status of an adjacent port from an adjacent device having the adjacent port accommodating a link accommodated in a port of a self-device;
- a determination unit determining whether or not a loop of a frame is generated based on an inconsistency between a status of the port of the self-device and the status of the adjacent port;
- and
- a blocking unit blocking the port of the self-device when determined that the loop is generated.
A method for staying a loop of a frame, comprising:
- acquiring a status of an adjacent port from an adjacent device having the adjacent port accommodating a link accommodated in a port of a self-device in a network in which a frame of a datalink layer is forwarded;
- determining whether or not a frame loop is generated based on an inconsistency between a status of the port of the self-device and the status of the adjacent port;
- and
- blocking the port of the self-device when determined that the loop is generated.
A program for controlling a computer to execute the steps of:
- acquiring a status of an adjacent port from an adjacent device having the adjacent port accommodating a link accommodated in a port of a self-device in a network in which a frame of a datalink layer is forwarded;
- determining whether or not a frame loop is generated based on an inconsistency between a status of the port of the self-device and the status of the adjacent port;
- and
- blocking the port of the self-device when determined that the loop is generated.
