Description: This MIB is applicable to router-devices. It's made for RCR (Resilient Controllable Routing). RCR provides an effective resolution which can dynamically auto-adjust outbound traffic to the optimal external interface by monitoring the performance and traffic load of each external interface. It provides the functions of intelligentized traffic load distribution and the optimal external interface selection. This can optimally utilize the external interfaces. Furthermore, RCR realized the function which can select the optimal external interface based on different classes of operation flow.
