Abstract: Combining lower layer network tests and upper layer network tests is disclosed. A method includes receiving a user selection to create an upper layer test and a lower layer test, receiving upper layer test information and lower layer test information, displaying a first timeline showing the activity of the upper layer test in a first pane and a second timeline showing the activity of the lower layer test in a second pane. Synchronization between the lower layer tests and upper layer tests may be defined. The method allows for observing and ascertaining the impact of the lower layer tests on the upper layer tests. The method may be implemented in software, stored on a storage medium and performed on a network testing system that includes one or more network cards and in one or more network testing systems.

Abstract: Data communication optimization is disclosed. In a method, when data transmission is requested, an outgoing data unit is prepared with dummy payload data. In a method, when data reception is requested, the header and validation information from an incoming data unit is provided while the payload of the data unit is ignored. The methods cause an increase in the throughput of a network card when transmitting and/or receiving a data units having a large payload. The methods may be achieved on a hardware device included on a board in a network testing system and/or with associated software.
