Connection Cluster Requirements When the Servers Are in Separate Buildings or Sites Depending on the number of voice messaging ports on each Connection server, the path of connectivity must have the following guaranteed bandwidth with no steady-state congestion: –For 48 voice messaging ports on each server—50 Mbps –For 96 voice messaging ports on each server—100 Mbps –For 144 voice messaging ports on each server—150 Mbps •The maximum round-trip latency must be no more than 20 ms. •The network must use the following load-balancing techniques for connections to the Connection servers: –The Connection servers are assigned a common DNS name with the Connection publisher server first. –All user client and administrator sessions connect to the Connection publisher server. If the Connection publisher server stops functioning, the user client and administrator sessions must connect to the Connection subscriber server. –Phone systems must attempt to route incoming calls to the Connection subscriber server. If no voice messaging ports are available to answer calls on the Connection subscriber server, the phone systems must route calls to the Connection publisher server. •The Connection servers must not be separated by a firewall.
