Communication network monitoring

摘要

Techniques described herein generally include methods, devices and systems related to monitoring a flow of data packets in a communication network. Some example devices may include one or more of a stream capture unit, and/or an analyzer. The stream capture unit can be coupled to a communication network, and configured to monitor a flow of data packets associated with communication steams in the communication network, and identify a first stream of data packets and a second stream of data packets from the monitored flow of data packets. The first stream and the second stream are associated with a single destination. The analyzer can be coupled to the stream capture unit and configured to identify an event associated with from the first stream identified by the stream capture unit, identify information related to the identified event from the second stream identified by the stream capture unit, and determine a response based on the event and the information related to the event.

1. A monitoring device configured to monitor a flow of data packets associated with communication streams in a communication network between a first end point and a second end point, the monitoring device comprising:
a stream capture unit coupled to the communication network and the second end point, wherein the stream capture unit is configured to
monitor the flow of data packets associated with the communication streams in the communication network from a same point on the communication network, andidentify a first stream of data packets and a second stream of data packets from the monitored flow of data packets, wherein the first stream and the second stream are multiplexed onto an association between the first end point and the second end point; and an analyzer, coupled to the stream capture unit, wherein the analyzer is configured to:
identify an event associated with the first stream identified by the stream capture unit,identify information related to the event from the second stream identified by the stream capture unit,determine a cause for quality of service related issues associated with the communication network or quality of experience related issues at the second end point based on the event and the information related to the event, anddetermine a response based on the determined cause.
