Methods, systems, and computer readable media for classifying application traffic at a network traffic emulation device that emulates multiple application servers are disclosed. The method may include, at a network traffic emulation device, providing a plurality of different application flows for monitoring mixed application traffic received from different client applications via a device under test on the same transport layer port. For each of the different application flows that monitor the same transport layer port, parsing a payload of received packets associated with the same session in the mixed application traffic and identifying non-matching application flows based on whether a portion of each payload matches a signature associated with the application flow. The method further includes eliminating, as identification candidates, non-matching application flows from the application flows that monitor packets received on the same transport layer port until an application flow that identifies an application for the received packets associated with the same session remains.

Methods, systems, and computer readable media for generating simulated network traffic from a plurality of different traffic flows and maintaining a configured distribution among the flows are disclosed. One exemplary method includes determining a number of operations per flow for each of a plurality of flows that generate simulated network traffic between the flows and a device under test. The method further includes determining a desired traffic distribution among the traffic generated by the traffic flows. The method further includes assigning a weight to each flow that determines the number of times to execute each flow during execution of a batch of flows. The method further includes executing the flows in batches according to the assigned weights to transmit the desired distribution of traffic between the different flows and the device under test.

Methods, systems, and computer readable media for adjusting load at a device under test are disclosed. According to one method, the method occurs at a testing platform. The method includes determining whether a current operations rate associated with a device under test (DUT) is near a target operations rate, wherein the current operations rate is associated with one or more simulated users being simulated by the testing platform. The method also includes adjusting the current operations rate by increasing or decreasing the number of simulated users interacting with the DUT in response to determining that the current operations rate associated with the DUT is not near a target operations rate.

Methods and apparatus to test connection rate of a network device. T connections between a test system and the network device may be defined and C connections of the T connections may be initiated in each of a plurality of sequential time intervals, where T and C are positive integers and T&#x3e;C. Connection identifiers associated with active connections and inactive connections may be stored in first-in first-out active and idle queues, respectively. Connection identifiers associated with the initiated connections may be moved from the head of the idle queue to the tail of the active queue. When a number NI of connection identifiers in the idle queue at the start of a time interval is less than C, C&#x2212;NI connections associated with connection identifiers at the head of the active queue may be aborted and re-initiated.
