Slide 20 of 26
Notes:
- For 98% of all traffic (in bytes) successfully inferred a demand. Promising but does not necessarily mean we have the right demands. To check this, we used our routing model. Of the 98%, 95 to 99% consistent with our OSPF simulation. This is for all traffic, inbound, output, and a third class of ětransitî traffic between peers. Other consistency tests also successful.
- Outbound: via the disambiguation procedure, 67% disambiguated. Of the 33% remaining, we found about 15% disambiguated to border routers in the same physical location (city). Traffic from that set of routers takes essentially the same paths.
- Inbound traffic: all contributed to the first bullet. Results are good.
- Outbound traffic: where cannot disambiguate consider measurements at certain customer-side links (e.g., hosting centers), responsible for heavy traffic. Otherwise, to get the last 15% accounted for in TE logic, would have to model distribution among the possible inputs.
