Jari,
MAPPING RESOLUTION
===============
The caching design has a number of issues:
- If packets are dropped while cache entries are being fetched, there
may be deterministic loss
- If packets are routed through a secondary path while cache entries are
being fetched, there may be deterministic delay
Both of these are issues (draft-thaler 3.1.6-3.1.7). Exactly how serious
issues is left for further study, however.
In addition, all designs with a mapping resolution system may have
incentive and reliability issues due to the fact that a third party is
needed. And, the non-caching design may have scalability issues.
Although this has not yet been largely discussed on the mailing list, I
think that we should add that the security of the mapping resolution
system is a concern. The mapping system should take security into
account while few of the existing proposals have addressed this issue.
