How much will CPS reduce my CI usage ?

This is probably the most common question asked and is a difficult one to answer.

First, each Connector will have different traffic patterns, so just because one Connector reduces their CI load by 50% doesn't mean other Connectors will see the same thing.  

Second, Internet'2 Commercial Peering Service is still fairly new (started in October of 2006).    As Internet2 gets connected to additional exchange points and establishes new peerings relationships, the reductions in CI usage can increase dramatically.   In some cases, an single peer network can off-load as much as 10-15% of a Connector's overall CI usage.

In general, the current Internet2 CPS Connectors are seeing a 30-40% reduction in CI usage (as of April 11, 2007).
