For the combined dedicated link in this example, the results are as follows:

Total Link = 2,550,000 bps

Router/Logger high-priority bandwidth queue of 264,000 bps

PG high-priority bandwidth queue of 1,998,000 bps

If this example were implemented with two separate links, Router/Logger private and PG private, the 
link sizes and queues would be as follows:

Router/Logger link of 330,000 bps (actual minimum link is 1.5 Mb, as defined earlier), with 
high-priority bandwidth queue of 264,000 bps

PG link of 2,220,000 bps, with high-priority bandwidth queue of 1,998,000 bps

When using Multilink Point-to-Point Protocol (MLPPP) for private networks, Cisco recommends the 
following attributes for the MLPPP link:

Use per-destination load balancing instead of per-packet load balancing.

You must have two separate multilinks with one link each for per-destination load balancing.

Enable Point-to-Point Protocol (PPP) fragmentation to reduce serialization delay.

For details about Unified CCE clustering over the WAN, see 

.

Bandwidth must be guaranteed across the highly available (HA) WAN for all Unified ICM private, 
public, CTI, and Unified CM intra-cluster communication signaling (ICCS). Moreover, bandwidth must 
be guaranteed for any calls going across the highly available WAN. Minimum total bandwidth required 
across the highly available WAN for all Unified CCE signaling is 2 Mbps.

In addition to the bandwidth requirements for the private and public networks, this section adds 
bandwidth analysis for the connections from Unified IP IVR or Unified CVP PG to Unified IP IVR or 
Unified CVP, CTI Server to CTI OS, and Unified CM intra-cluster communication signaling (ICCS).
