Every year the University contracts for a finite amount of aggregated Internet access. In order to provide the expected service level to traffic related to core institutional activities, choices must sometimes be made regarding traffic priorities. Goal: No one application will affect the total network usage by consuming an inordinate amount of the University internet/intranet network bandwidth. OIT will intercede in normal traffic routing and flow as little as possible. It is not the goal of OIT to inhibit general use of the Internet or campus networks. Implementation: OIT will set time-dependent rate limits, when needed, on any application or protocol which exceeds established parameters. In order to set differentiating guidelines, we have classified applications into two separate categories. One (Primary) are those applications which have general consensus as having merit and purpose to the core mission of the University of Minnesota (teaching, education and research) and Secondary applications are those which may prove to have significant bandwidth requirements and as such impede core mission applications.Primary applications include:HTTP (web browser)SMTP, POP, IMAP (e-mail)DNS (address information)Other applications that use less than 7% of total internal or external network capacity.Secondary bandwidth priorities include:Applications not listed above that use more than 10% (or an updated percentage determined by the CIO) of total internal or external network capacity with provisions for specific exceptions (e.g. research requirements) that may be made by approval of the CIO.

Consultation and Notification: When intervention measures are necessary, every effort will be made to work with campus populations who utilize the said application(s) to arrive at mutually agreeable methods of controlling or minimizing campus resources impact. When rate-limiting methods are determined necessary, these will be put into place and approved by the CIO, who will then notify the appropriate faculty governance committees.
