摘要： Methods and apparatus for collecting, storing, processing and using data, such a RMON2 network traffic data, are described. Network traffic probes are identified and attempts are made to configure the identified probes to generate network traffic data sets which are as close to a preselected common data format as possible. Application layer traffic data is collected in addition to network layer traffic data when possible. In an RMON2 embodiment, the common data format includes the use of delta count values as opposed to absolute count values. The common data format of the present invention utilizes terminal count mode format as opposed to all count mode format for the presentation of RMON2 application layer information. To minimize the amount of data processing required to put a probe's network traffic data into the desired common format and to maximize the amount of information collected, network data is obtained from a probe using one of the available RMON2 table formats. The utilized format is selected in the following order of preference: alMatrixTopN(Terminal Mode), alMatrixTopN(AllMode), alMatrix, nlMatrixTopN and nlMatrix.

摘要： A method, and a system for implementing the method, for implementing the method, for determining if a wire has been miswired in a network comprising service nodes and switch elements. The method includes the steps of: (1) transmitting a transmission stream in an outbound route, (where this transmission stream includes one or more service node fields for one or more service nodes, one or more switch element fields for one or more switch elements connected to the one or more service nodes, and a port field for each the switch element); (2) if the transmission stream is received on a port at a the switch element different than a the port field for the switch element indicated by the transmission stream, then setting an error indicator in the transmission stream; (3) transmitting the transmission stream back to the one or more service nodes in a return route, where the one or more service nodes determine from the error indicator a miswired condition between the receiving switch element and a previous switch element or service node along the outbound route. The one or more service nodes can record, store and tabulate the miswired condition and one or more additional miswired conditions. The transmission stream can store the one or more switch element fields for the one or more switch elements and the port fields for each the switch element separately for a path comprising the outbound route and a path comprising the return route.
