  1. Networking costs Estimation of costs for campuses Jean-Paul Le Guigner Jplg@cru.fr

  2. Contributors • Brian Gilmore (Edindburg university) • David Williams (Terena and CERN) • Jean-Paul Le Guigner (Universities in France) If you strongly disagree and wish to punch some one in the face don’t look elsewhere

  3. The goal • Estimation of the costs for : • the different components of campus networking • supporting teams • connectivity to the NREN and the Internet. Varies from country to country (need more work) Almost deterministic if agreement on rules Depend on the committment of the university and the extend of services provided by the team

  4. Assumptions and guidelines • One campus • medium size (in the european standard) • 15000 undergraduate students • 1500 staff (with post-graduate) • 10 000 installed Ethernet ports • 5 000 active simultaneously • Costs are expressed by installed ports (wired) • Depreciation • Cabling (local, inter-building, MANs, …)  15 years, • Equipment 5 years.

  5. Items of cost (if you had to pay for all) • Cabling the proximity (wired, wireless) • Interconnecting buildings to reach the core network • Equipments : • Switches from local ports to network core • Core routers, switches, security and basic services equipments • Personnel (installation, supervision, maintenance, services) + [MANs, [Regional network]] , NREN

  6. Internet Res. & Educ. Internet NREN Includes GEANT and CIT • Very simple case • Total cost = campus costs + NREN costs!

  7. Internet Res. & Educ. Internet NREN MAN Leased circuit A bit more complex : add the NREN costs + MAN costs and even in some cases leased circuits.

  8. Internet Res. & Educ. Internet NREN Regional network Even more complicated for Some countries (France, Spain, …)  Need to add costs of regional nets. MAN

  9. Details (you can read in deliverable D18)

  10. Details (you can read in deliverable D18)

  11. Remarks (1) • All the numbers proposed may be subject for discussion • particularly NRENs and Regional network costs per port • and the cost of supporting teams • Wireless will soon spread all around the campuses • this will lower the costs a bit but not so much actually • and security is still an issue, which put constraints on the network architecture and the personnel in charge • wired (copper or even fiber) will still be necessary for medium and high levels of usage.

  12. Remarks (2) • Personnel costs is one of the major item in the list and if we want to have well managed, reliable and secured networking with up to date technology it’s not going to decrease. • Smaller sites need to spend even more on this chapter to get real good expertise. They of course can share expertise and services with others (easy to say  ).

  13. That’s the end for me (and today) not for this study may be.
