  • **Thank Chris** For those of you who don’t recognize me, I’m the guy that used to raise his hand at CCSP if the speaker asked “Is anyone from URHnet here?” I moved over to CITES last fall for a change of scenery and to narrow my focus a little, though you can’t tell for the 2 panels and 1 “gotta be there” session today. Middle of an RFP, can’t say much Want to give an update anyway What we’ve done, what we are doing, where we are headed and maybe a new service
  • 6 Internal CITES meetings with representatives from most of the divisions Open ended question asking for input from IT Alliance using the CITES wiki Part of a meeting with the NUTAG group, several very good points of input and suggestions And some unofficial input from several other places
  • Have to leverage an existing authentication store, not another password to remember Have to leverage an existing authorization store, don’t want to re-invent the wheel and I don’t want to hand manage “X gets this domain, Y gets that” IPv6 is coming, our reciprocal offsite DNS secondary, Indiana, has it today, requests have come in, but only a few. BIND views, if you aren’t familiar with the concept, allows different answers to be given based on the source of the question For example, On campus vs Off campus views, for private IP space Dynamic DNS support Mail infrastructure for campus and many others in the CITES Datacenter peak at over 2500 queries/sec, rest of campus regularly hits 1200 queries/sec New Centralized service?
  • If you’ve dealt with an RFP before, you know the drill. If you haven’t, well, this one is a little odd and drawn out because of the nature of what we are trying to do. A couple of months gathering input A month writing the RFP Most of February posted on the Higher Ed Procurement site Actually got it in hand in early March, most of a month scoring the responses (note that Spring Break is in there) Vendors were on site during Finals week, evaluation equipment is here this month BoT if we are over the magic dollar amount, I hope not. July/August/later if forced
  • 1 “resident expert” from CS Had to keep the group small so that we could find a time to meet and make a decision fairly quickly
  • DNS is a utility, just like the power company, no one notices when it works, everyone notices when it breaks. Hopefully, the average user doesn’t even notice we’ve changed something, unless they are a “power user” and notice one of the new features. ITPros should notice an interface change, - we hope to offer some “one time, one record” tools in the portal, which Chris will talking about and - a new service, which I’ve hinted at
  • And, that new service, might be: DHCP! URHnet has ~10500 IPs leased, many other CITES services use DHCP
  • Can’t say much else, the RFP is still out there
  • Chris described what kinds of uses it will have. I’ll describe how we can accomplish it. Some goals: Externally consistent and convenient, providing the right capability to various kinds of users in one place Internally must be rapidly extensible, generalize well to future needs, supportable Performance must scale to meet demands for high-volume network data reporting, network troubleshooting, and other use Maintain a useful historical record for resource and problem analysis and other business functions. We’re building a platform! Not just an application. (We are using model apps to design the platform, but will build to suit!) Three-tiers, each layer suited to do a particular function well Flexibility: We can select the best solutions for specific jobs Wide Integration: We can leverage and improve existing systems Agile: Applications can be insulated from backend changes. Facilitates gentle evolution and migration paths Well-defined: We can support a set of capabilities instead of a “database”.

      • New service?
  • DHCP Service
    • CITES has multiple services that can leverage a centralized, managed DHCP service.
    • Once this service is stable and proven reliable, CITES plans to offer DHCP services to networks on an opt-in basis.
    • No, centralized DHCP will not be forced on anyone.
    • Architecture will be highly available, redundant, monitored and managed just like any other critical campus service.
