Abstract
According to an example method, it is determined that a first network node in a ring network is claimed by a first managing device and a second network node in the ring network is claimed by a second managing device. The ring network includes a single link to a customer network. The second network node is then isolated from the first network node. A separate linear network is formed including the second network node. Upon reset of the second network node to an unclaimed status, the second network node is claimed by the first managing device.
Claims20
A method comprising:
- determining, by a first network node in a ring network, that the first network node is managed by a first managing device and a second and a third network nodes in the ring network are managed by a second managing device, wherein the ring network has a first link to a customer network, and wherein the second managing device is configured to manage the ring network;
- in response to the determination, isolating the first network node from the ring network by disabling, by the first network node, flow of data traffic between the first network node, and the second and third network nodes;
- forming a separate second link to the customer network in response to the isolation wherein the first and second links are not part of the ring network;
- and
- resetting the first network node to remove association with the first managing device;
- and
- joining the ring network under management of the second managing device.
A first network node in a ring network, comprising
- a hardware controller configured to:
- determine that the first network node is managed by a first managing device, and a second and a third network nodes in the ring network are managed by a second managing device, wherein the ring network has a first link to a customer network, and wherein the second managing device is configured to manage the ring network;
- in response to the determination, isolate the first network node from the ring network by disabling, by the first network node, flow of data traffic between the first network node, and the second and third network nodes;
- and
- form a separate second link to the customer network in response to the isolation, wherein the first and second links are not part of the ring network;
- and
- a ring module configured to:
- reset the first network node to remove association with the first managing device;
- and
- join the ring network under management of the second managing device.
A non-transitory machine readable storage medium comprising instructions that when executed cause a computer to:
- determine, by a first network node in a ring network, that the first network node is managed by a first managing device, and a second and a third network nodes in the ring network are managed by a second managing device, wherein the ring network has a first link to a customer network and a single ring protection link owner, and wherein the second managing device is configured to manage the ring network;
- in response to the determination, isolate the first network node from the ring network by disabling, by the first network node, flow of data traffic between the first network node, and the second and third network nodes;
- form a separate second link to the customer network in response to the isolation, wherein the first and second links are not part of the ring network,
- reset the first network node to remove association with the first managing device;
- and
- join the ring network under management of the second managing device.
