Abstract: The present invention discloses a method for detecting abnormal network packets, which is applied to a packet distributing unit in a network. The packet distributing unit exchanges a plurality of network packets with a plurality of network devices on an extranet, and records a destination IP address, a destination port number and a network packet output time of the network packets specifically outputted within at least two time periods, every time before the packet distributing unit sends these specific output network packets out, then the packet distributing unit compares these specific output network packets in different time periods to determine whether or not there are data having the same output time, same destination IP address and same destination port number; if yes, then the packet distributing unit issues a warning report.

Abstract: A network connection apparatus testing method is proposed. The method first provides a first terminal apparatus having at least an inlaid test program and a test parameter, and a second terminal apparatus having a packet capturing program and an execution parameter, then enables the first terminal apparatus to transmit a group of testing data packets to the second terminal apparatus, and counts a number of the test data packets that have been transmitted until the number is equal to a setting value of the test parameter. The method then counts a number of the test data packets received by the second terminal apparatus, compares the test parameter with the number of the received test data packets, and calculates a receiving rate of the test data packet. The method therefore judges the efficiency of the connecting port assembled in a network connection apparatus according to the receiving rate.

Abstract: A network equipment testing method and system is proposed, which is designed for use with a network system based on a server-client architecture for implementing a data transmission reliability testing procedure concurrently on one or more pieces of network equipment, and which is characterized by the utilization of a universally acceptable and recognized network testing standard for performing a data transmission reliability testing procedure.
