This page contains a bandwidth allocation by link of this traffic for purposes of network design, QoS, prioritization etc.
Traffic Types | Priority (Descending order) | La Serena - Santiago (Leased + Lambda) | Santiago to Miami (Leased + Lambda) | Miami to Chicago (Shared + Esnet) | Chicago - Champaign | ||||
Case 1 | Case 2 | Case 3 | Case 4 | Case 5 | Case 6 | Case 7 | Case 8 | ||

Bandwidth Reservation for LSST (Lambda/Spectrum + Leased) | 25% | 12% | 25% | 38% | 75% | 38% | 75% | 0% | |
NOTES: | |||||||||
[1] Guaranteed reservation | Shared via Leased | ||||||||
[2] Expected use, Prioritized/QoS | Dedicated via Spectrum | ||||||||
[3] Carried on AURA circuits, not LSST. Fail-over from AURA to LSST is not baselined. | |||||||||
[4] Combinations of Cases use numbers from lowest performance case | |||||||||
[5] All numbers are stated in line speed reservation, efficiency may lower actual delivered BW | |||||||||
[6] Cases of total network failure" on a link, i.e. all paths connecting two points are not shown. Those cases rely on data buffering and catch-up. |
