Re: jitter testing

["bart knippenberg" <bartknippenberg () gmail com>]

Hello Markus,

some Vendors implement this on there routers egg Cisco ip SLA. Values
can than be read by an snmp client. You can find more information on
the cisco site if you want. How other vendors implement this I do not
know but they propably also have a similar feature.

Best regards
