Abstract: Methods, computing devices, and computer readable storage media for testing network connections are disclosed. A first processor of a plurality of processors may define a new TCP connection to be opened. The first processor may apply a hash function to determine a second processor of the plurality of processors to open the new TCP connection. The first processor may provide data defining the new TCP connection to the second processor. The second processor may open the new TCP connection in accordance with the data provided by the first processor.

Abstract: Methods, port units, and computer readable storage media for testing network connections are disclosed. A plurality of Transmission Control Protocol (TCP) connections with one or remote devices may be established via a network. Metadata may be extracted from TCP packets transmitted via the plurality of TCP connections and TCP packets received via the plurality of TCP connections. The extracted metadata may be stored in a memory.

Abstract: A first node that transmits TCP packets to and receives TCP packets from a second node splits a target TCP packet throughput across multiple consecutive time slots, each slot having a target throughput value. If a current slot's achieved throughput value does not match the current slot's target throughput value, the target throughput value for the current slot and/or a subsequent slot is adjusted. Transmit throughput from the first node to the second node is controlled by transmitting TCP packets from the first node to the second node according to a target throughput value for the current slot. Receive throughput from the second node to the first node is controlled by dynamically calculating an advertised receive window size according to a target throughput value for the current slot and communicating the advertised receive window size to the second node.

Abstract: Methods, computing devices, and computer readable storage media for testing network connections are disclosed. A first processor of a plurality of processors may define a new TCP connection. The first processor may apply a hash function to determine an appropriate one of the plurality of processors to open the new TCP connection. The first processor may write data defining the new TCP connection to a queue associated with the appropriate processor. The appropriate processor may retrieve the data defining the new TCP connection from the queue and open the new TCP connection.

Abstract: Methods and computer readable storage media to test secure network connections. One or more pre-calculated encryption data (PCCD) sets may be defined in accordance with a secure communications protocol. The one or more PCCD sets may be stored in a first PCCD memory and a second PCCD memory located respectively within a first port unit and a second port unit of a plurality of port units. Each PCCD set may include at least a first parameter and a second parameter generated by encrypting the first parameter. A simulated secure connection between the first port unit and the second port unit via a network under test may be opened using a selected PCCD set from the one or more PCCD sets without performing decryption processing.

Abstract: Methods, computing devices, and computer readable storage media to test network connections using a port unit having a plurality of processors. A plurality of transmission control protocol (TCP) connections to be initiated by the port unit during a test session may be defined.
