Abstract
A data relay apparatus that recovers a failure in a network that shares a part of a plurality of rings and avoids occurrence of a loop path by providing a block in each of the rings includes a failure-notification-packet transmitting unit that transmits, when a failure is detected in a shared portion of a ring, a failure notification packet to a predetermined redundancy-providing ring; and a block setting unit that sets a block that blocks a main signal by passing through a control packet at a port where the failure is detected.
Claims18
A data relay apparatus that recovers a failure in a network that shares a part of a plurality of rings and avoids occurrence of a loop path by providing a block in each of the rings, the data relay apparatus comprising:
- a failure-notification-packet transmitting unit that transmits, when a failure is detected in a shared portion of a ring, a failure notification packet to a predetermined redundancy-providing ring;
- and
- a block setting unit that sets a block that blocks a main signal by passing through a control packet at a port where the failure is detected.
A failure recovery method for a data relay apparatus that recovers a failure in a network that shares a part of a plurality of rings and avoids occurrence of a loop path by providing a block in each of the rings, the method comprising:
- transmitting, when a failure is detected in a shared portion of a ring, a failure notification packet to a predetermined redundancy-providing ring;
- and
- setting a block that blocks a main signal by passing through a control packet at a port where the failure is detected.
