Technique for handling a status change in an interconnect node

A computer program product stored in a non-transitory computer readable medium for status change handling in an interconnect node, the computer program product comprising software instructions which, when run on one or more computing devices of the interconnect node, causes the interconnect node to:

• receive, by the interconnect node and from another node, a first indication of a given service for which a change has been or is about to be performed, the given service having a data plane that is active in the interconnect node and passive in the other node as a backup to the active data plane;
• exchanging data plane roles with the other node, the exchanging comprising passivate the data plane of the interconnect node, by the interconnect node and in response to receiving the first indication, the passivating comprising selectively changing the data plane of the interconnect node from active status to passive status with respect to the given service;
• transmit, upon completion of the passivation of the data plane of the interconnect node, a second indication of the passive status of the data plane of the interconnect node with respect to the given service from the interconnect node to the other node.

A method for status change handling in an interconnect node, wherein the method is performed in the interconnect node and comprises:

• transmitting, to another node, a first indication of a given service for which a change has been or is about to be performed, the given service having a data plane that is active in the other node and passive in the interconnect node as a backup to the active data plane;
• exchanging data plane roles with the other node, the exchanging comprising awaiting reception, from the other node, of a second indication that the data plane of the given service in the other node has been set to passive status, and in response, activating the data plane of the given service in the interconnect node, the activating comprising selectively changing the data plane of the given service in the interconnect node from passive status to active status.

A device for status change handling in an interconnect node, the device comprising:

• at least one processor configured to:
• transmit, to another node, a first indication of a given service for which a change has been or is about to be performed, the given service having a data plane that is active in the other node and passive in the interconnect node as a backup to the active data plane;
• exchange data plane roles with the other node, the exchange comprising awaiting reception, from the other node, of a second indication that the data plane of the given service in the other node has been set to passive status, and in response, activating the data plane of the given service in the interconnect node, the activating comprising selectively changing the data plane of the given service in the interconnect node from passive status to active status.
