Systems and methods for providing a boundary scan test of a wired or wireless network having a plurality of network nodes are presented. The system includes a test station communicatively coupled with the network. The test station creates a MAC layer scan test route sequence that includes each link in the network and is independent of the routing mechanism and protocol used for the network. The test station also creates a test agent that is configured to traverse each link in the scan test route sequence. The test agent is then deployed on the network and information about a link is reported back to the test station after the test agent examines the link. The scan test route sequence can be created by sending out a series of broadcast messages from one or more nodes in the network, sequentially applying a network tour to cover the entire network, or performing a depth first search on the entire network.

The invention relates to a tide predicting method for the tide is influenced by various factors, including cyclical factors, such as tidal generation force, and non-cyclical factors, such as wind power, atmospheric pressure, coast characteristics, rainfall, dip angles of the lunar orbit and the like. The predicting accuracy of the traditional harmonic analysis method is influenced by partial tide number, and the traditional harmonic analysis method cannot analyze the influence of non-cyclical factors; the artificial neural network method developed recent years overcomes the defect that the non-cyclical factors cannot be predicted by the harmonic analysis method to a certain extent, but has great data volume required by study training samples and wide involve range, can cover various possible conditions, but has less station historical data of non-cyclical factors.
