摘要： A method of providing topology information about a network to a topology manager is disclosed. The network includes a plurality of sensors each having a sensor ID, and the method includes performing the following steps at each of the plurality of sensors: receiving a stream of packets and identifying a topology trace packet in the stream of packets, wherein the topology trace packet has a destination address and an ID of a previous sensor, including the sensor ID in the topology trace packet, sending the topology trace packet to the destination address, forming a report message so as to include the sensor ID, the previous sensor ID, sending the report to the topology manager; and, providing network addresses of adjacent nodes to the topology manager.

摘要： A method of monitoring packet traffic is provided. The method includes: at a first access point, capturing portions of traffic packets passing therethrough separated by time intervals; encapsulating the portions of traffic packets thereby forming encapsulated packets and adding timestamps to the encapsulated packets so as to preserve the portions of traffic packets and information related to the time intervals; transmitting the encapsulated packets over a network; decapsulating the encapsulated packets so as to obtain replay packets and the capture timestamps, wherein the replay packets include the portions of the traffic packets; and, transmitting the replay packets separated by the time intervals, wherein the timestamps are used to reproduce the time intervals so as to imitate the traffic packets passing through the first access point.
