RELIABLE SYSTEMS AND METHODS FOR NETWORK NOTIFICATIONS
First Claim
1. A method of reliable network notifications, comprising:
- at a first device, communicating network management to a second device;
generating a notification at the first device;
transmitting information to the second device with the notification;
buffering subsequent notifications for the second device at the first device;
receiving an acknowledgement of the information at the first device from the second device; and
transmitting any buffered subsequent notifications to the second device.

Abstract
The present disclosure provides reliable systems and methods for network notifications, i.e. Simple Network Management Protocol version 2 Protocol Data Unit (SNMPv2-Trap-PDU) messages, asynchronous notifications, InformRequest-PDU messages, and the like, between network elements, element managers, and other element managers. In an exemplary embodiment, the present invention includes a network management system and method with a plurality of network elements operating a management agent communicatively coupled to an element manager which in turn is communicatively coupled to another element manager, a network management system (NMS), an operations support system (OSS), or the like. The present invention may utilize SNMPv2 and/or v3, and includes various techniques and processes ensuring reliable notifications between any of the network elements, element managers, or the like in the network management system.

11. A method of reliable network notifications, comprising:
-
at a first device, communicating network management to a second device; generating a notification at the first device; transmitting the notification from the first device to the second device with a logical identifier within the notification, wherein the logical identifier is utilized to identify any missing notifications from the first device to the second device; receiving the notification at the second device; examining the logical identifier; if no prior notifications are missing, processing the notification at the second device; and if prior notifications are missing, requesting missing notifications by the second device to the first device. - View Dependent Claims (12, 13, 14, 15, 16)

17. A network management system, comprising:
-
one or more managed network elements; an element manager communicatively coupled to the one or more managed network elements; and a network manager communicatively coupled to the element manager; a first reliable notification mechanism between the one or more managed network elements and the element manager ensuring delivery of each notification therebetween; and a second reliable notification mechanism between the element manager and the network manager ensuring delivery of each notification therebetween. - View Dependent Claims (18, 19, 20)
