PHYSICAL LOOP DETECTION METHOD AND AN APPARATUS BETWEEN THE PORTS OF A NETWORK CONNECTING APPARATUS CAPABLE OF HAVING A PLURALITY OF PORT

摘要

PURPOSE: A physical loop detection method and an apparatus are provided to provide a method and an apparatus capable of detecting a physical loop between the ports of a network connecting apparatus such as a dummy hub, and a method and an apparatus capable of recognizing the physical loop generation between the ports of the network connecting apparatus by a user, by notifying the physical loop generation between the ports to the user.;CONSTITUTION: A method for detecting a physical loop between the ports of a network connecting apparatus(210) having a plurality of port comprises following steps: a step(410) consecutively applying a pulse signal to each of the plurality of port, a step(430) determining whether a signal outputted through each of the plurality of port is a normally outputted signal, a step(450) notifying the physical loop generation between the ports of the network connecting apparatus if the determination result shows that the pulse signal is not normally outputted, and a step(470) of stopping the consecutive application of the pulse signal if the determination result shows that the pulse signal is not normally outputted.;COPYRIGHT KIPO 2013;[Reference numerals] (410) Consecutively applying a pulse signal to each of the plurality of ports; (430) Is the signal outputted through each of the plurality of ports a normal signal?; (450) Notifying physical loop generation between the ports of a network connecting apparatus; (470) Stopping the consecutive application of the pulse signal; (490) Is the signal outputted from the outside?; (AA) Start; (BB) End
