Routing protocol interface for generalized data distribution
First Claim
1. A method comprising:
- dynamically registering, by an application executing on a network device and via an interface of a routing protocol process executing on the network device, a new address family identifier that identifies application data for the application;
receiving, by a management interface process via an interface of the management interface process, a display function for the new address family identifier;
receiving, by the routing protocol process from a peer network device, a routing protocol advertisement according to a routing protocol, wherein the routing protocol advertisement includes data and includes the new address family identifier to identify the data as application data for the application;
formatting, by the management interface process according to the display function for the new address family identifier, the data to generate formatted data; and
outputting, by the management interface process for display at a display device, the formatted data.

Abstract
In general, techniques are described for defining an interface to a network router software infrastructure that allows developers to dynamically extend a routing protocol executed by the network router to distribute data throughout the routing domain for use with custom applications. In some examples, a routing protocol process executing on a control plane of a network device may expose an interface, such as an Application Programming Interface (API), that defines methods and parameters for extending the operation of a routing protocol executed by the routing protocol process. Third-party developers may then build custom applications that invoke the interface of the routing protocol process to define new routing protocol messages or message payloads, inject application-specific data into the routing protocol process for distribution within the newly defined messages/payloads, and extract application-specific data that is carried by newly defined messages/payloads that are originated by another network device in the routing domain.

8. A method comprising:
-
dynamically registering, by a network device during run-time operation of the network device and via an interface of the network device, a new address family identifier that identifies application data for an application; receiving, by the network device, a display function for the new address family identifier; receiving, by the network device from a peer network device, a routing protocol advertisement according to a routing protocol, wherein the routing protocol advertisement includes data and includes the new address family identifier to identify the data as application data for the application; formatting, by the network device according to the display function for the new address family identifier, the data to generate formatted data; and outputting, by the network device, the formatted data.

9. A network device comprising:
-
a memory; at least one processor coupled to the memory; a routing protocol process configured for execution by the at least one processor;
an application configured for execution by the at least one processor to dynamically register, via an interface of the routing protocol process, a new address family identifier that identifies application data for the application; anda management interface process configured for execution by the at least one processor to receive, via an interface of the management interface process, a display function for the new address family identifier, wherein the routing protocol process is further configured to receive, from a peer network device, a routing protocol advertisement according to a routing protocol, wherein the routing protocol advertisement includes data and includes the new address family identifier to identify the data as application data for the application, wherein the management interface process is further configured to format, according to the display function for the new address family identifier, the data to generate formatted data, and wherein the management interface process is further configured to output, for display at a display device, the formatted data. - View Dependent Claims (10, 11, 12, 13, 14, 15)
