    摘要： A computer-implemented method for discovering network topologies. The method may include (1) receiving, on a host system within a network, a switch-protocol message that includes a switch identifier, a port identifier, and/or a root path cost, (2) identifying a set of switches within the network based on the switch-protocol message, (3) determining how the set of switches are connected based on the switch-protocol message, and (4) mapping a topology of the network based on determining how the set of switches are connected. Various other methods, systems, and computer-readable media are also disclosed.

    摘要： Detection of network devices (e.g., stealth devices) and mapping network topology are performed via network introspection by collaborating endpoints/nodes. The method includes receiving (e.g., by a node on a network) an assignment to be a supernode that will manage multiple agents of a subnetwork within an overall network. This assigned supernode instructs two or more of the agents to perform a set of network traffic fingerprinting tests of the subnetwork by passing information across the subnetwork to each other. The supernode receives results of the tests from the clients and detects one or more intermediate devices located between the clients based on an effect of the intermediate devices on the information passed between the clients. The supernode can further map the topology of the subnetwork (including the detected devices) which can be used in mapping the overall network topology.
