Detecting and isolating dropped or out-of-order packets in communication networks

A processor-implemented method for analyzing dropped or out of order data packets that are sent from an initiating device over a communications network, comprising:

• monitoring, by a processor, a plurality of ports corresponding to a network communication device, wherein the network communication device comprises a switch device and a network adapter device;
• setting, by the processor, a defined threshold for a number of dropped or out of order data packets in an exchange with the network communication device;
• receiving, by the processor, a plurality of data packets in the exchange from the initiating device to the network communication device via the communications network;
• determining, by the processor, at least one of the of the data packets in the exchange that are dropped or received out of order, wherein the at least one of the data packets in the exchange that are dropped based on determining header information that is corrupt, and wherein the header information is determined to be corrupt based on determining at least one of missing header information, invalid header information, and unreadable header information;
• accessing, by the processor, a header portion corresponding to the at least one of the data packets in the exchange that are dropped or received out of order, wherein the accessed header portion comprises information associated with the network communication device at which the one or more of the data packets in the exchange are dropped or received out of order, wherein the information associated with the network communication device comprises switch port information corresponding to the switch device and network adaptor information corresponding to the network adaptor device and
• writing, by the processor, the header information of the at least one of the data packets in the exchange that are dropped or received out of order into a table or log on the network communications device.

A non-transitory computer-readable recording medium for storing a computer program for analyzing dropped or out of order data packets that are sent from an initiating device over a communications network, wherein the computer program comprises:

• receiving a predetermined plurality of test data packets from the initiating device over the communications network;
• determining at least one of the predetermined plurality of test data packets that are dropped or received out of order, wherein the at least one of the predetermined plurality of test data packets are dropped based on determining header information that is corrupt, and wherein the header information is determined to be corrupt based on determining at least one of missing header information, invalid header information, and unreadable header information;
• accessing a header portion corresponding to the at least one of the predetermined plurality of test data packets that are dropped or received out of order, wherein the accessed header portion comprises information associated with a network communication device at which the at least one of the predetermined plurality of test data packets that are dropped or received out of order, wherein the network communication device comprises a switch device and a network adapter device, wherein the information associated with the network communication device comprises switch port information corresponding to the switch device and network adaptor information corresponding to the network adaptor device;
• writing the header information of the at least one of the predetermined plurality of test data packets that are dropped or received out of order into a table or log on the network communications device;
• and
• sending the accessed header portion to the initiating device, wherein the accessed header portion includes information associated with a device location at which the one or more of the predetermined plurality of test data packets are dropped or received out of order.

A system for analyzing dropped or out of order data packets that are sent from an initiating device over a communications network comprising:

• a memory;
• and a processor disposed in communication with the memory and configured to issue processing instructions stored in the memory to:
• receive a predetermined plurality of test data packets from the initiating device over the communications network;
• determine at least one of the predetermined plurality of test data packets that are dropped or received out of order, wherein the at least one of the predetermined plurality of test data packets are dropped based on determining header information that is corrupt, and wherein the header information is determined to be corrupt based on determining at least one of missing header information, invalid header information, and unreadable header information;
• access a header portion corresponding to the at least one of the predetermined plurality of test data packets that are dropped or received out of order, wherein the accessed header portion comprises information associated with a network communication device at which the at least one of the predetermined plurality of test data packets that are dropped or received out of order, wherein the network communication device comprises a switch device and a network adapter device, wherein the information associated with the network communication device comprises switch port information corresponding to the switch device and network adaptor information corresponding to the network adaptor device;
• write the header information of the at least one of the predetermined plurality of test data packets that are dropped or received out of order into a table or log on the network communications device;
• and
• send the accessed header portion to the initiating device, wherein the accessed header portion includes information associated with a device location at which the one or more of the predetermined plurality of test data packets are dropped or received out of order.
