Embodiments of the invention include a system for preventing a packet of a test pattern from being communicated over a network. In one embodiment, a communications management system is disclosed that includes a network interface configured to enable the communications management system to communicate with a plurality of network nodes over a network. The communications management system further includes a processor configured to execute instructions to determine whether one or more portions of the network are congested, and generate and transmit a message to at least one of the network nodes to terminate communication of test packets in response to a determination that one or more portions of the network is congested.
