The actual problem is more complicated

Hi Kishi,

Imagine running a network where both the intranet and internet links run a variety of network protocols including:

1) Latency-sesitive high-bandwith applications such as VOIP.
2) Intermittant, high bandwidth applications such as downloading Linux ISO's.

Add to this a large number of protocols on the intranet such as NFS and X11 and you can see that this can be a management issue.

I don't actually think that auditing is normally the solution. Rather it is important to understand the nature of the biggest offenders and plan for them. Obviously in the case of VOIP, if you don't plan, you *will* eventually get jitter and poor voice quality. This means that *all* internal routers and gateways between the internet and intranet must support QoS and have this effectively managed. All unplanned-for-protocol can go through a default queue where they are not expected to be latency-sensitive. Then when a problem occurs you have pretty good idea of what is causing the problem but it is limited to that one application (and you can add a queue for it or move it to a different queue).

Best Wishes,
