Abstract: The present invention relates generally to networking, and more particularly to techniques and products for verifying, qualifying and/or quantifying the performance of networking devices and infrastructure. According to certain aspects, test equipment according to embodiments of the invention performs stress tests using both client and server emulation with very low overhead, providing a virtually unlimited number of servers and/or clients. According to further aspects, tests include the transfer of real files between clients and servers, not just test patterns. According to further aspects, test equipment includes an easy to use Web GUI interface. According to further aspects, tests are performed using TCP protocol, which is the predominant form of network traffic.
