The current progress of network technique and the complication of network structure make administrators must spend more time and mind to maintain the system and the network under normal operation. With continuously increasing dependence on the network, it seems to be a knotty matter to know how to effectively manage all equipments on the network and to make sure they whether run it rightly or not. To make a comprehensive survey of present administrator's management mode, administrators have to quite understand themselves rule network's each equipmental IP and the entire topology structure to rapidly and efficiently tend more and more complicated network environment, which work fine in most small-scale network environments, but not in slightly large-scale environments that reveal the vitalness of leading into automation management to relieve the burden of administrator towards network management. This essay's presenting an cross-layer topology discovery Algorithm (Automatic Cross-Layer Topology Discovery) that can work on network layer and data-link layer based on Simple Network Management Protocol (SNMP) that is widely used by each network administrator nowadays. It can be automatic exploration through random knotted dot, and possesses the feature of cross-layer and multiple protocols to support exploration of heterogeneous network, possesses quicker and more effective explorative ability of topology resource. The implement way will rely on the standard of the mutual communicative protocol to automatically discover the entire network topology and all network equipped link dot from integration to open source code's network-managed system to prove the CLTD Algorithm is effective.
