Description (partial)


A 7600 router running the inline video monitoring feature may report a spurious high DF (delay factor) when a dynamic change is made to jitter being induced by a impairment generator. This is seen for one interval only and the correct value of the impairment gets reported from the next interval onwards.


This issue is only seen when artificial impairment is induced via a test equipment. Real-world video flows with continuously varying jitter get correctly monitored, and DF gets reported correctly.
