CDA Deployment Recommendations

It is recommended to consider the following aspects while deploying CDA:

 • Cisco CDA interoperates with the consumer devices using the UDP protocol. Therefore, it is recommended for CDA to be located geographically near the consumer devices. This is mainly important when CDA sends bulk data to the consumer device, which can be time consuming over the WAN.

 • It is recommended that any CDA node in the deployment receive all user login information from the Active Directory Domain Controllers. This will allow consumer devices to interoperate with the local CDA for all user logins data. Moreover, having the Active Directory Domain Controller geographically near the CDA will increase reliability.

 • To achieve high availability you can use two CDAs with the same configuration where both CDAs must retrieve same user login information from the same Active Directory Domain Controllers. It is the role of the consumer device to switch to the second CDA in case the first CDA is non-responding.
