File control for data packet routers using consensus and inter-planetary file system (IPFS)
Packet routers route data packets based on existing topology files. The packet routers hash the existing topology files into content-addressed objects and exchange the content-addressed objects. One of the routers modifies its topology file into a new topology file, hashes the new topology file into a new content-addressed object, and transfers the new content-addressed object to the other packet routers. The packet routers exchange the content-addressed objects, and in response, exchange the topology files. The routers establish a consensus on the new topology file based on the existing topology files. The one packet router routes additional data packets based on the new topology file in response to the consensus. In some examples, the content-addressed objects comprise Inter-Planetary File System (IPFS) objects.
1. A method of operating a data communication network to control router topology with content-addressing, the method comprising:
packet routers routing data packets based on existing topology files, hashing the existing topology files into existing content-addressed objects, and exchanging the existing content-addressed objects;
one of the packet routers modifying one of the existing topology files into a new topology file, and in response, hashing the new topology file into a new content-addressed object and transferring the new content-addressed object to the other packet routers;
the packet routers exchanging the existing content-addressed objects, and in response, exchanging the existing topology files;
the other packet routers transferring the new content-addressed object to the one of the packet routers, and in response, receiving the new topology file from the one of the packet routers;
the one of the packet routers receiving the new content-addressed object from the other packet routers, and in response, transferring the new topology file to the other packet routers;
the packet routers establishing a consensus on the new topology file based on the existing topology files; and
the one of the packet routers routing additional data packets based on the new topology file responsive to the consensus.

the packet routers configured to exchange the existing content-addressed objects, and in response, exchange the existing topology files;
the other packet routers configured to transfer the new content-addressed object to the one of the packet routers, and in response, receive the new topology file from the one of the packet routers;
the one of the packet routers configured to receive the new content-addressed object from the other packet routers, and in response, transfer the new topology file to the other packet routers;
the packet routers configured to establish a consensus on the new topology file based on the existing topology files; and
the one of the packet routers configured to route additional data packets based on the new topology file responsive to the consensus.
