Determining when routes may be advertised by a network device in the context of asynchronous hardware platform processing code responses

A network device, comprising:

• an interface system;
• a memory system;
• and
• a control system configured to:
• receive, via the interface system, information regarding a forwarding information base (FIB) sequence number;
• place the FIB sequence number into a FIB sequence number queue implemented in the memory system;
• assign the FIB sequence number a new state;
• receive a route processing request including an indication of a route and a platform sequence number associated with the FIB sequence number;
• assign the FIB sequence number a sent-to-platform state;
• place the route processing request into a route-associated queue corresponding to the route, the route-associated queue being implemented in the memory system;
• receive a route processing response corresponding to the route and corresponding to one or more processing requests, including at least the route processing request;
• remove the route processing request from the route-associated queue;
• assign the FIB sequence number a processed state;
• and
• publish the FIB sequence number.

One or more non-transitory media having instructions for controlling a network device to perform a method stored thereon, the method comprising:

• receiving information regarding a forwarding information base (FIB) sequence number;
• placing the FIB sequence number into a FIB sequence number queue;
• assigning the FIB sequence number a first state;
• receiving a route processing request including an indication of a route and a platform sequence number associated with the FIB sequence number;
• assigning the FIB sequence number a second state;
• placing the route processing request into a route-associated queue corresponding to the route;
• receiving a route processing response corresponding to the route and corresponding to one or more processing requests, including at least the route processing request;
• removing the route processing request from the route-associated queue;
• assigning the FIB sequence number a third state;
• and
• publishing the FIB sequence number.
