We were discussing Riverbed Operating System (RiOS) technical concepts. We were looking at the management streamlining functions. The controller and the console were used for this purpose. The central management console provides touchless feature. It provides aggregated or individual device reporting, group based configuration policies and scheduled operations. It also provides trends upto a years worth of data and drilldrowns for more granular data. This is a web interface that also facilitates over the wire software upgrades, global SSL certificate management and an easy to use QoS rules configuration interface. One of the things administrators look for when optimizing WAN traffic are those that are the heaviest users of bandwidth and they are referred to as "Top Talkers" . This is useful for both security monitoring as well as for accounting purposes.  Top Talkers together with NetFlow give a lot of WAN transparency.
While the console manages the devices, the Controller provides central management capabilities for the clients. The SMC enables easy deployment of mobile client software to remote users via MSI packages. It also integrates with Active Directory or LDAP for access control. The controller also provides license management, job scheduling and notifications to extend its administrative capabilities.
Next we look at the deployment options for RiOS. We mentioned the plug-in interface for RiOS appliances in any network topology and scalability due to its adherence to the networking fundamentals instead of specific architectures or setups such as tunnels. Consequently it requires less involvement during deployment. Even legacy devices and networks are compatible with this kind of appliances - since there are no changes expected or required from the network. Changes such as tunnel configurations, DFS changes, client drive mapping changes, plugins router configurations, route injection, or any other overhead required for competitive solutions are avoided. This implies that RiOS devices can be installed in networks as large as using satellite infrastructure or as connected as full mesh MPLS networks.
