RE: staffing guidelines

I'm sure it varies greatly based on the type of work that's being done, but my experience with another company led me to think that one set of eyes could handle up to about 200-300 devices, purely for monitoring and outage management. Configuration and support was another matter. (When I say devices I mean routers, servers, and manageable switches) To get at a 24x7 figure, I generally multiplied by about 4 or 5 (taking into account shifts, vacations, weekends, etc.) So, for about, say, 1,000 manageable devices, I would expect to need about 16-20 people. The curve improves significantly as you grow and get to use more sophisticated problem isolation methods and tools. -----Original Message----- From: Irwin Lazar Sent: Thu 2001-10-04 14:26 To: 'nanog(a)merit.edu' Cc: Subject: staffing guidelines Is anyone aware of guidelines for IT staffing that are freely available on the web?

who doesn't aggregate?
by R.P. Aditya 04 Oct '01

Below is a list of the top 20 origin ASes in terms of advertising prefixes smaller than the registry allocations in a particular prefix range. Although the total number of "extra" routes represented by these top 20 is a small percentage of the global tables, these are many of the entities that would have the most routers to upgrade as the number of prefixes grows...one imagines it would be in their best self-interest to clean up shop and aggregate better esp since they are also comprise the few that run default-free...(funny, I don't see 2914 in that list *grin*) smd, you should hit these guys up first for your prefix-maint fund. Thanks to pfs(a)cisco.com for including this in his stats (and if you have complaints about being publically shamed, blame me for urging him to include it in his reports).

Re: Carnivore alternative
by Eliot Lear 04 Oct '01

Hank, Indeed when the FBI visited with NANOG in Washington D.C., the guy stated pretty plainly that if you didn't want to use Carnivore you didn't have to. You merely needed to provide the information listed in the warrant. Now I'm not a provider, and I can't verify what he said, but that is what he said. On the other hand, what assurance is there that there is no trap door in NetWitness. What one might do is place filters on the port that connects such devices so as to limit the intercept to information that could be conceivably covered by the warrant. I've heard from some ISPs that they would rather the FBI not even tell them who the target is, for fear of the information leaking. Strange legal jungle we live in. Comments? (So, Ran, got both barrels loaded, yet? ;-) Eliot ----- Original Message ----- From: "Hank Nussbacher" <hank(a)att.net.il> Sent: Wednesday, October 03, 2001 9:45 PM Subject: Carnivore alternative > > http://www.theregister.co.uk/content/6/21992.html > > Hank >

netsol: not processing requests?
by Eric S. Hvozda 04 Oct '01

04 Oct '01

Anyone out there notice a slow down or lack of processing requests at netsol (ie verisign, whatever their name is now)? We did some maintenance yesterday and only received 2 of the "do you agree with this change" emails. Yet we received all the "we have received your request" emails for all changes. Changes that we approved we never got the "your change has been completed" emails and yet we did the maintenace around 1-3pm EDT yesterday. Anyone will similar experience out there?

No more MMDS fixed wireless networks?
by Christopher J. Wolff 04 Oct '01

04 Oct '01

Hello folks, I heard today that Sprint is ready to capitulate to the FCC and reassign the radio spectrum it occupies in most major markets (MMDS) to mobile use. I guess they will be shutting off the Sprint Broadband Internet product in 30 days. Can anyone corroborate this? Regards, Christopher J.
