Abstract
A network monitoring system having a router for generating flow records and a monitor device for filtering flow records, extracting internet address information of the remote hosts from the flow records and performing active tests on selected remote hosts. For at least some data packets, the router sends a flow record of the data packet to the monitor. Each flow record contains address, port, and subnet information of the filtered data packet. Based on the information provided by the flow records, the monitor can perform active tests on the selected remote hosts.
Claims27
A method to monitor a network by a network monitor, comprising:
- routing data packets through a router;
- generating flow records for at least some of said data packets;
- filtering said at least some of the flow records;
- extracting packet information from the filtered flow records, wherein the extracted packet information comprises internet information of at least one target of interest;
- and
- performing active measurements to said target of interest using the extracted packet information.
An apparatus for monitoring a network, comprising:
- a router for routing data packets, wherein said router generates flow records for at least some of said data packets;
- and
- a monitor for receiving the flow records, wherein said monitor filters said flow records, and further wherein said monitor extracts packet information from said filtered flow records, the extracted packet information comprising internet information of at least one target of interest, wherein said monitor performs active measurements to said target of interest using the extracted packet information.
A method to monitor a network by a network monitor, comprising:
- routing data packets through a router;
- generating flow records for at least a fraction of said data packets;
- extracting packet information from at least a fraction of said flow records, wherein the extracted packet information comprises internet information of at least one target of interest;
- and
- performing active measurements to said target of interest using the extracted packet information.
