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

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

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

8 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

9 MSC Closet Rehab: BEFORE

10 AFTER

11 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

12 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

13 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

14 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

15 154 Terabytes of storage Fiber channels and NFS cannels Main fiber rack for server room

16 College of Nano Science and Engineering An Inside Look at CNSE

17 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
