File control for data packet routers using consensus and inter-planetary file system (IPFS)
A data packet router uses Inter-Planetary File System (IPFS) and consensus to control file modifications. The router routes data packets based on a networking file. The router modifies the networking file. The router generates a new IPFS object from the modified networking file. The router obtains consensus on the new IPFS object from neighbor routers. The routers use previously approved IPFS objects to retrieve topology data and achieve consensus on the modified networking file based on the topology data. In response to the consensus, the router routes data packets based on the modified networking file.
