Sizing and Licensing
Sizing and Licensing
The following guidelines apply when sizing various components in a Unified Expert Advisor
deployment:
deployment:
•
Unified Expert Advisor
Unified Expert Advisor is licensed according to the number of Cisco Unified Presence users that
may be configured as expert advisors and the number of servers in the cluster. There is no separate
limit to the number of expert advisors who may be logged in or actively connected to callers.
Licenses are strictly enforced, but all license checking is performed at configuration time.
may be configured as expert advisors and the number of servers in the cluster. There is no separate
limit to the number of expert advisors who may be logged in or actively connected to callers.
Licenses are strictly enforced, but all license checking is performed at configuration time.
Currently each Unified Expert Advisor cluster supports up to 3000 expert advisors and up to 6000
busy hour call attempts (BHCA) on Cisco MCS-7845 servers. See the chapter on
busy hour call attempts (BHCA) on Cisco MCS-7845 servers. See the chapter on
, for complete details about supported Unified Expert
Advisor capacities under various conditions.
•
Network Bandwidth
Outside of normal SIP and telephony network guidelines, the only significant bandwidth occupied
by Unified Expert Advisor is in the link between each runtime server and the reporting server.
Reporting event traffic for the number of calls and expert advisors indicated above is about 1.6
megabits per second. No special QoS or latency minimums are required.

•
Cisco Unified Communications Manager (Unified CM)
With some older Cisco IOS releases on the gateway, when you size Unified CM for Unified Expert
Advisor deployments, it is important to take into account that an MTP resource is required for all
calls on the SIP trunk that connects to Unified CVP or its SIP proxy server. (See
Advisor deployments, it is important to take into account that an MTP resource is required for all
calls on the SIP trunk that connects to Unified CVP or its SIP proxy server. (See
.)
•
Cisco Unified Presence
Each Unified Expert Advisor runtime server logs one presence user (who must be fully licensed)
into Cisco Unified Presence. During startup of either runtime server or of the presence server itself,
and every 30 to 60 minutes thereafter, the system goes through the process of subscribing for
presence notifications from each configured expert. This process can take several minutes to
complete, during which time the presence server experiences a heavy load. However, the presence
server works together with Unified Expert Advisor to inject delays as necessary so that the presence
server does not become overloaded. Once the systems reach steady state, the presence server load is
equal to the number of configured experts issuing typical presence updates to each of the two
runtime server presence users.

•
Cisco Unified Presence SIP Proxy Server
The load is relatively light, equivalent to about 3 SIP dialogs and 8 to 20 IM messages per call,
depending on the number of AQ broadcasts.
