H04L 1/00

US Classification:

370229, 3702362, 3702411, 370252, 370325, 370353, 370354, 370355, 370356, 370468, 370230, 370231, 370235, 4554521, 455453, 455518, 455519, 455520

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.

International Classification:

H04J 3/14

H04L 12/56

US Classification:

370236, 370242, 370389, 370252

Abstract:

In one embodiment, a router examines an incoming packet for a flow monitoring request. The router may examine every packet for the flow monitoring request, or preferably may only examine packets including a lifetime value indicating that the packet should be dropped and not forwarded or may only examine packets having a predetermined message format. When the flow monitoring request is included, the router performs detailed flow analysis or other monitoring according to the flow monitoring request.

H04M 3/22
H04M 1/24

US Classification:

379 3201

Abstract:

A method for adaptive media quality monitoring includes monitoring at least one metric of a call between at least two endpoints and detecting a threshold crossing event via the monitoring of the at least one metric. The method also includes executing a threshold crossing action based on detecting the threshold crossing event. The threshold crossing action comprises monitoring at least one additional metric of the call.

Appl. No.:

11/740784

Inventors:

Robert Biskner - Santa Barbara CA, US

Assignee:

CISCO TECHNOLOGY, INC. - San Jose CA

International Classification:

H04L 12/56

US Classification:

370392

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.
