Hi Monia,

'Burst' is a very broad term. It would be useful to clarify to what you are
referring.. I can think of a few possibilities:

- Data Transmission: The length of an uninterrupted flow of information.
- Traffic Engineering: The ability for traffic to temporarily exceed it's
allocated (average) bandwidth share.
- Internal Event: A backup (scheduled) or a server failure (adhoc) altering
traffic patterns.
- External Event: Marketing campaign / event coinciding with increased
traffic towards say, a website.

Perhaps -> Over what period of time is a 'Burst'..?


Cheers,
Heath
