20 Claims

1. A method for providing network-based data packet monitoring and recovery, the method comprising:

continuously monitoring, by one or more computer processors of a disaster recovery device, a database on a communication server for gaps in network traffic data sent from an edge device to the communication server, wherein the disaster recovery device monitors and stores data packets generated by a specific set of edge devices and sent to the communication server;

determining, by the one or more computer processors, whether at least one gap in the network traffic data is identified in the database on the communication server;

responsive to determining that at least one gap in the network traffic data is identified in the database on the communication server, determining, by the one or more computer processors, missing data packets associated with the at least one gap from a data packet archive on the disaster recovery device;

determining, by the one or more computer processors, whether there is active network traffic between the edge device and the communication server; and

responsive to determining that there is active network traffic between the edge device and the communication server, replaying, by the one or more computer processors, the missing data packets in the active network traffic between the edge device and the communication server.
