| How many e-mail transactions occur each day? How many people have Personal Web pages? How many people use Penn State dial-up services? The chart below provides an at-a-glance view for ASET's wide-range of services. For project details, refer to the New, Improved and Continued Services and/or the Project/Initiative Hightlights sections of this report. |
| Service | Stats |
|---|---|
| Access Accounts | approx. 110,000 at any given time |
| Friends of Penn State (FPS) Accounts | Total: 181,772 Migrated: 106,799 (includes old Access Accounts) |
| Directory Services | 134,000 entries 150,000 queries/day |
| Calendering via CorporateTime | 1211 customers 73 customers for handheld synchronization |
| VPN Connections (from a non-Penn State network) |
300 connections/day |
| Dial-up Connections | an average of 22,385 connections/day average length of call is 72 minutes |
| Web Space Directories | Personal: 46,839 Departmental: 156 Course: 685 Clubs: 657 |
| Hits to www.psu.edu | Two million/day |
| E-mail transactions | 3.5 million/day POP: 58,100/day; 71,300/week KPOP: 37,430/day; 54,226/week WebMail: 37,300/day; 54,346/week IMAP: 60/day; 60/week |
| E-mail Spam Filtering | 1 - 4 million spam messages/day |
| Virtual Hosts A virtual host is a computer which can be setup to respond to multiple IP addresses and provide various services, typically different Web services, on each. Each IP address, which usually has its own hostname, operates as if it is a separate host on a separate machine, although it is really the same host. For example, a Penn State department can choose to have departmental Web space at http://www.psu.edu/some_dept/ and request the virtual host http://www.some_dept.psu.edu/. Requests for virtual hosts are sent and billed through CSS' ILSD program and ASET sets up the virtual host. |
