Abstract
Systems and methods for automatically accommodating one or more connections associated with a network resource targeted for maintenance in a network include receiving a request identifying the network resource for the maintenance; responsive to the network resource carrying no traffic, blocking the network resource during the maintenance; and, responsive to the network resource carrying traffic, attempting local recovery on all connections of the traffic to move the connections off of the network resource based on action at the local node, and, for the connections unable to locally recover, performing a network action through a control plane in the network to move the connections unable to locally recover off of the network resource.
Claims20
A method for automatically accommodating one or more connections associated with a network resource targeted for maintenance at a local node in a network, the method comprising:
- receiving a request identifying the network resource for the maintenance;
- responsive to the network resource carrying no traffic, blocking the network resource during the maintenance;
- and
- responsive to the network resource carrying traffic, attempting local recovery on all connections of the traffic to move the connections off of the network resource based on action at the local node, and, for the connections unable to locally recover, performing a network action through a control plane in the network to move the connections unable to locally recover off of the network resource.
An apparatus adapted to automatically accommodate one or more connections associated with a network resource targeted for maintenance at a local node in a network, the apparatus comprising:
- circuitry adapted to receive a request identifying the network resource for the maintenance;
- circuitry adapted to block the network resource during the maintenance responsive to the network resource carrying no traffic;
- and
- circuitry adapted to attempt local recovery on all connections of the traffic to move the connections off of the network resource based on action at the local node, and, for the connections unable to locally recover, circuitry adapted to cause a network action through a control plane in the network to move the connections unable to locally recover off of the network resource, responsive to the network resource carrying traffic.
A node in a network adapted to automatically accommodate one or more connections associated with a network resource targeted for maintenance at a local node in a network, the node comprising:
- one or more ports;
- and
- a controller communicatively coupled to the one or more ports, wherein the controller is configured to
- receive a request identifying the network resource for the maintenance,
- block the network resource during the maintenance responsive to the network resource carrying no traffic, and
- attempt local recovery on all connections of the traffic to move the connections off of the network resource based on action at the local node, and, for the connections unable to locally recover, circuitry adapted to cause a network action through a control plane in the network to move the connections unable to locally recover off of the network resource, responsive to the network resource carrying traffic.
