How it is Used on Campus |
| TCP/IP |
A suite of communication protocols that include the Transmission Control Protocol, Internet Protocol and many others. TCP/IP defines the logical addressing scheme as well as traffic routing, error-correction and flow control methods used on the Internet. |
Each network node (computer, printer, game console) is assigned an IP address from the address space owned by the college. This space is usually expressed as 138.78.0.0/16 and has roughly 65k addresses. |
| FTP/sFTP |
The File Transfer Protocol (FTP) and Secure File Transfer Protocols (sFTP) define methods for transferring data between computers. Both protocols utilize TCP/IP for addressing, error correction and flow control. Additionally, sFTP provides encryption to protect the data while it is in transit. |
Using clients that support these protocols, FTP/sFTP can to be used to access to home drives (G: ) and some other shared folders from the residence hall network, wireless network or the Internet. |
| Traffic Shaping |
Generic Traffic Shaping or rate-limiting is used to ensure that no one network node or type of traffic can over utilize a network connection. GTS is also used to smooth traffic before transmittal over a WAN link |
Used to approximate fair-use on the Colleges Internet connection |
| iSCSI SAN |
(Internet SCSI Storage Area Network) A Storage Area Network is a high-speed network used to interconnect storage devices and the servers that utilize the storage. iSCSI or SCSI-over-IP is used to transmit the server-to-storage module commands over any network medium that supports TCP/IP |
The College operates an iSCSI based SAN with an aggregate capacity of 10 TB. Faculty, Staff and Student home drives (G:) as well as department shared drives and other data are stored on the SAN. |
