Network connectivity measurement system and method

A system for detecting a transient outage of an Internet Protocol (IP) network, the system comprising:

• a probe sending device configured to perform operations comprising sending a stream of probe packets over the IP network, wherein each probe packet comprises a probe sequence number and a timestamp value issued by the probe sending device;
• a probe receiving device configured to perform operations comprising:
• receiving a current probe packet, wherein the current probe packet comprises a current probe sequence number and a current timestamp value issued by a probe sending device;
• overwriting probe packet data obtained from a last received probe packet with the current probe packet when the current probe sequence number exceeds the sequence number of the last received probe packet by one, wherein the last probe packet comprises a last probe sequence number and a last timestamp value issued by the probe sending device;
• and
• storing probe packet data obtained from the current probe packet when the current probe sequence number exceeds the sequence number of the last received probe packet by more than one.
