the report generation module is used for generating a report from the route registration result and sending the report to clients in each province;
the RADB route acquisition module is specifically used for:
synchronizing the routing information of the RADB to a local library of the IRRD;
synchronizing routing information of a local library of the IRRD to a Mysql database;
completing the route information acquisition of the RADB;
the BGP route acquisition module of the device is specifically configured to:
establishing IBGP neighbor relation between RR and each intra-province BGP routing device, and transmitting BGP routing information acquired from the IBGP neighbor to all IBGP neighbors of RR;
the acquisition machine establishes an IBGP neighbor relation with the RR and receives BGP routing information sent by the RR;
a route analysis program deployed on the acquisition machine analyzes BGP route information into a local mysql database;
if the prefix in the RADB route information is strictly equal to the prefix in the BGP route information, and the ORIGINAS is equal to the route registration record of the AS to be registered, the registration is judged, otherwise, the registration is judged not to be registered.
4. The route registration integrity rate evaluation device of claim 3, wherein the judgment rule in the route registration integrity rate calculation module is as follows:
if ASPATH is empty, the community does not contain no-advertisement and no-export, and the route granularity is greater than or equal to/24, and the route is in the self address range, the route is a provincial convergent route;
if the route PEERAS is an in-network public AS, the ORIGINAS is an in-network public AS, the community does not contain no-advertisement and no-export, the granularity of the route is greater than or equal to/24, and the route is in an own address range, the route is an in-provincial detail route;
if ASPATH is empty or route PEERAS is an in-network public AS, orignias is an in-network public AS, the community does not contain no-advertisement and no-export, the granularity of the route is greater than or equal to/24, and the route is not in the self address range, such route is a multicast route;
if the route PEERAS is public AS in the network, ORIGINAS is public AS but not in the AS number range in the network, the communication does not contain no-advertisement and no-export, and the granularity of the route is greater than or equal to/24, the route is the intra-provincial client route;
among the routes that should be registered, the route that includes 4134:111 or 4134:2400 is the necessary registration range.
5. A computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the processor implements the method of any of claims 1-2 when executing the computer program.
6. A computer readable storage medium, characterized in that the computer readable storage medium stores a computer program for executing the method of any one of claims 1-2.
