Full Title or Meme
Distributed Consistency in Identity Management is required when more than one process might be assigning identifiers that are required to be unique.
Context
- Decentralized Consistency is an easier problem when each Registration Authority is given control of a portion of a name space where it can control registration.
- With the advent of fully distributed systems where any one machine could desire the ability to create an identifier, this problem needs a practical resolution.
Problems
- Coordination is tricky to implements and expensive in terms of latency added.
Solutions
- CALM[1]
