Internet2 fee model and capacity-augment policy

Citation: Internet2, 2025 Higher Education Fee Model Details, internet2.edu/wp-content/uploads/2024/11/2025-higher-education-fee-model-details.pdf; Internet2, "Internet2 IP Backbone Capacity Augment Practice," internet2.edu/community/about-us/policies/internet2-ip-backbone-capacity-augment-practice/.

Type: Provider policy documentation. Key findings used in this graph:

• Sustaining Contributions are determined by institutional research and total expenditures, not traffic volume — bandwidth is contractual flat-rate.
• Backbone circuits flagged for discussion at 30% week-over-week 95th-percentile utilization; 40% sustained utilization triggers capacity augment.
• 50% headroom maintained on connections between regionals, Internet2, and campuses by policy.

These figures support C-0006: incremental traffic from Tier 3 protocol participation is absorbed entirely by the existing flat-rate contract and well below the policy headroom.
