Many-to-many synchronization

In the many-to-many synchronization pattern each replica exchanges packets with all other replicas.

Advantages:
  • For companies with few sites, this pattern keeps each replica’s epoch table the most accurate for all siblings.
  • If one site is unavailable, the other sites do not have to change their patterns to continue synchronizing.
Disadvantages:
  • Each administrator must maintain more synchronization jobs and spend more time keeping track of packets.
