Abstract

A tool for network-based package monitoring and recovery. The tool scans a database to identify a gap in network traffic data. The tool determines whether at least one gap in the network traffic data is identified in the database, wherein the at least one gap is a gap in communication between a target device and a communication serve. Responsive to a determination that at least one gap in the network traffic data is identified, the tool determines a missing package from a package archive. The tool determines whether there is active network traffic between the target device and the communication server. Responsive to a determination that there is active network traffic between the target device and the communication server, the tool replays the missing package in the active network traffic between the target device and the communication server.

Claims20

Dependent claims

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.

3 more elements

A computer program product for providing network-based data packet monitoring and recovery, the computer program product comprising:

one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the stored program instructions comprising:
program instructions to continuously monitor, via 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;
program instructions to determine whether at least one gap in the network traffic data is identified in the database on the communication server;
program instructions to, responsive to that at least one gap in the network traffic data is identified in the database on the communication server, determine missing data packets associated with the at least one gap from a data packet archive on the disaster recovery device;
program instructions to determine whether there is active network traffic between the edge device and the communication server;
and
program instructions to, responsive to determining that there is active network traffic between the edge device and the communication server, replay the missing data packets in the active network traffic between the edge device and the communication server.

4 more elements

A computer system for network-based data packet monitoring and recovery, the computer system comprising:

one or more computer processors;
one or more computer readable storage media;
and
program instructions stored on at least one of the one or more computer readable storage media for execution by at least one of the one or more computer processors, the stored program instructions comprising:
program instructions to continuously monitor, via 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;
program instructions to determine whether at least one gap in the network traffic data is identified in the database on the communication server;
program instructions to, responsive to determining that at least one gap in the network traffic data is identified in the database on the communication server, determine missing data packets associated with the at least one gap from a data packet archive on the disaster recovery device;
program instructions to determine whether there is active network traffic between the edge device and the communication server;
and
program instructions to, responsive to determining that there is active network traffic between the edge device and the communication server, replay the missing data packets in the active network traffic between the edge device and the communication server.
