Abstract
The present disclosure is directed to signaling a planned maintenance event between peering network devices, utilizing a specialized routing protocol message. A first network device may generate a maintenance notification message that includes a unique message-type code, a maintenance-type field, and an anticipated-duration field. The maintenance type field may specify a category of maintenance, such as a “Software upgrade” or a “User-initiated”, while the duration field may indicate an estimated time for session re-establishment. This message may also include a textual description field for additional context like reboot for maintenance type field “User-initiated”. The first network device may transmit the maintenance notification message to a second network device prior to or concurrent with temporarily terminating a peering session for the planned maintenance. Upon receipt of the message, the second network device may parse the fields and, via a policy engine, temporarily modify local policies. These modifications may include suppressing fault alarms related to the session termination, transitioning the session to a maintenance-pending state, or pausing reconnection attempts for the specified duration. The system may involve a network router comprising a processing module, a session manager, and a routing table configured to adjust metrics or path handling in response to the planned outage, thereby distinguishing the maintenance event from an unexpected failure and reducing network churn.
