Capacity/Load Ratios
Looking at the link capacity/average load
- Most ESnet links show ratios of a few to several tens
- The international links (CERN-Perryman (~4), DFN (~5), Italy (~4), KEK (~10), Canada (15)) show ratios of 4-15
- The worst link appears to be the MAE-W-ESnet link at about 1.5 ratio
However this may not be the bottleneck link
Notes:
For shared networks without some form of quality of service guarantees, one way to ensure excellent performance is to over-provision the links so they have sufficient capacity to handle instantaneous loads.
