What are the network latency limits (or Round Trip Times) in a scalable Meeting Server deployment?


In scalable and resilient Meeting Server deployments the following network latency limits (or Round Trip Times) apply:

The maximum RTT (Round Trip Time) between any two Meeting Server nodes in a cluster is 300ms.

But there are 4 special cases:

  1. The maximum RTT between clustered databases (DB-DB) is 200ms
  2. The maximum RTT between any call bridge and primary DB (Call Bridge-DB) is 200ms
  3. The maximum RTT between XMPP servers in a cluster (XMPP-XMPP) is 200ms (Note: XMPP is not supported from version 3.0 of the Cisco Meeting Server software)
  4. The maximum RTT between any two Call Bridges in a Call Bridge Group is 100ms
