A method for intelligent network topology mapping includes identifying network paths between a source and a destination, wherein identifying the network paths includes, for a hop in network topology: selecting a number of probe packets for revealing an expected number of next hops reachable from the hop; maintaining a list of flows reaching the hop; selecting, from the list, flow parameters for each of the probe packets; generating the number of probe packets and including the selected flow parameters in the probe packets; transmitting the number of probe packets to the hop; receiving responses to the probe packets; and recording network addresses of next hops revealed by the responses. The method further includes generating, from the network addresses of next hops, a network topology map illustrating the network paths.

The subject matter described herein includes methods, systems, and computer readable media for quiescence-informed network testing. One method for quiescence-informed network testing includes determining, by a first test agent, a quiescence state of the network. The method further includes reporting, by the first test agent and to a test controller, the quiescence state of the network. The method further includes configuring, by the test controller, the first test agent to execute a network test. The method further includes executing, by the first test agent, the network test. The method further includes reporting results of execution of the network test to the test controller.

Methods, systems, and computer readable media for receiving test configuration information are disclosed. According to one exemplary method, the method occurs at a node configured to operate in a private network. The method includes registering node identification information with a registration server. The method also includes sending a keep-alive message to the registration server. The method further includes receiving, in response to the keep-alive message and via the registration server, test configuration information from a configuration system outside the private network.

Methods, systems, and computer readable media for facilitating the resolving of endpoint hostnames in test environments with firewalls, network address translators (NATs), or clouds is disclosed. According to one exemplary method, the method occurs at a registration server configured to operate in a public network. The method includes receiving, from a first endpoint, a packet including a payload containing a first address and a hostname associated with the first endpoint. The method also includes identifying a second address from a header of the packet. The method also includes initiating, using the second address, a connection to the first endpoint. The method also includes determining whether the connection is successful. The method further includes associating the hostname of the first endpoint with one of the first address and the second address based on results of the determination.
