Abstract: A first network device determines flow statistics information associated with a flow. The first network device modulates the time-to-live (TTL) header field in a packet associated with the flow to include flow statistics information. The packet includes a header and a payload. The first network device transmits the packet to a second network device. The second network device demodulates the TTL header field to determine flow statistics information.

Abstract: A method for alert throttling in media quality monitoring, includes monitoring a plurality of active communication sessions. Each active communication session is between at least two endpoints. The method also includes detecting at least one quality-impacted communication session out of the plurality of active communication sessions. The method also includes generating a first alert for each detected quality-impacted communication session out of the plurality of active communication sessions until a first throttling number of quality-impacted communication sessions is detected out of the plurality of active communication sessions. Upon detecting the first throttling number of quality-impacted communication sessions, the method includes generating a second alert for each group of additional second number of quality-impacted communication sessions detected out of the plurality of active communication sessions.
