WiscNet Transit Share Service provides cost-effective "commodity Internet" transit service to research and education institutions whose fiber optic network facilities can connect to WiscNet fiber optic network facilities or its transit providers' facilities at Chicago, Illinois. To serve our Wisconsin member institutions, WiscNet commits to purchase transit service from national network providers at Chicago. WiscNet may re-sell available portions (or "shares") of our unused transit commitments. As a non-Wisconsin institution that commits to TransitShare, the Sharer may order from WiscNet a minimum "transit-commitment-share" delivered for an agreed period to the institution's network facilities at Chicago. Subject to availability, the Sharer or University may increase its share for an agreed time period.
