  1. DATACOMMUNICATIONS An overview of the University’s network By Jacob Pagendarm

  2. How Important is the Network?

  3. Network Devices • Core Router-The backbone of our network. It forwards information to/from a building to the data center, the Internet or to another building. • Edge Router-It’s job is to forward campus information to/from the Internet. • Aggregation Switch-Takes information from the core router and forwards to distribution switches • Distribution Switch-Delivers information to the end-user, wireless access point or controller. • WAP-Wireless access point

  4. CISCO 6513 • Router that feeds fiber to all of the buildings on campus • Central core of the entire university network.

  5. Apogee’s core network Fiber patch panels to each building(BDF closets)

  6. Data Closet • Fiber feeds to data closets in each building • Fiber feeds to switches in closets • Each jack for the given building is activated from a patch or krone panel into the switch

  7. MSC Closet Rehab: BEFORE

  8. AFTER

  9. Switches • Most popular model is the Cisco 2950 • Fiber distribution switch in each BDF feeds to closets • Switching gives 100 Mb/s to each port • Copper GBIC connection gives 1 Gb/s to one port • GBIC ports are where fiber is fed to from fiber panel • Switches are stacked using GBICS and stacking cables • Some switches are POE(power over Ethernet) • Voice over IP • Currently 288 data closets throughout 100+ buildings on campus

  10. Fiber Optics • Single mode(SM): can run 1GB/s or 10GB/s • Multi mode(MM): can run 1GB/s @ • Aqua fiber(MM): run 10GB/s @ • SC vs. LC vs. ST vs. MTRJ

  11. WAPS • Currently 428 WAPs on network(all campuses) • Wireless access point activated on designated ports on switches (VLANS) • Uses power injectors or POE switches • Can broadcast multiple SSIDS

  12. Server Room • Different servers serve purposes ranging from email to data backup and storage • The power is all run underneath the floor • The fiber is run above the server cabinets • A halon system removes oxygen in case of fire(Unique to UA) • Hot and Cold rows

  13. 154 Terabytes of storage Fiber channels and NFS cannels Main fiber rack for server room

  14. NanoFab Network • Building was designed to have data closets unlike the academic buildings due to age • Data closets are well organized with state of the art cable management systems • Network infrastructure increases at an alarming rate per year
