Bandwidth Management

The university's telecommunications network accommodates several thousand users on and off campus. The network is constantly monitored to measure network traffic volume, and adjustments are periodically made to maximize performance. Individuals operating network-attached devices which consume an excessive amount of bandwidth are subject to having their network bandwidth (or capacity) managed to ensure all users have appropriate network resources.

Although the parameters are subject to change, the maximum upload permitted from on campus residents to off campus destinations is 4.7GB, during a twenty-four (24) hour period. If that threshold is exceeded, the user will receive a warning notice. If excessive uploads continue for a subsequent twenty-four hour period, the user's bandwidth is limited to keep network traffic below the threshold. This referred to as "bandwidth management," and it continues until the user's networked device returns to an acceptable rate of consumption.

The threshold is one of many administrative tools used in a very dynamic network environment. It may be modified at any time to ensure that overall network objectives are met. The upload threshold meets the vast majority of the academic and leisure needs of on campus residents.

Excessive upload demand most often results from installation of peer-to-peer (p2p) or file-sharing applications, such as BitTorrent, on computers. Though p2p software is primarily used to download files, by default it puts you in the position of illegally sharing or uploading copyrighted music, movies or software, which generate a large volume of traffic to the Internet.

The next most common reasons are on-line game playing, video/audio chatting, or the initial backup of files to a cloud drive. Try decreasing the bitrate of video and audio being sent, turning off the HD (high definition) option on chat program and games. Play games over a local area network instead of the university network or Internet. Back up only about 20 GBs of data per 24 hours at a time.

Another reason may be that your computer has been infected with a virus. Follow all steps under the "CLEAN IT UP" section at to remove the virus.

If you are not aware of any action on your part that may have led to excessive consumption of network resources by your computer, it is possible file-sharing has been remotely established on your computer without your knowledge. This is easily accomplished on computers with weak or blank administrative passwords. Information about setting and changing passwords is available online.

If your connection is subject to bandwidth management, it is imperative that you locate and remove any file-sharing programs and copyrighted files you have not purchased and, that you immediately secure your computer.
