This object indicates the number of times that nodes contained within the 'scope of aggregation' have engaged the subscriber session throttle since the last discontinuity time. The mechanics of a subscriber session throttle vary with subscriber session type and implementation. However, the general concept of the throttle prevents a node from having to deal with more than a configured number of requests to establish subscriber sessions from the same CPE within the a configured interval of time. When the number of requests exceeds the configured threshold within the configured interval, then the node processing the requests engages the throttle. Typically, when a node engages a throttle, it drops requests from the CPE for some period of time, after which the node disengages the throttle. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of csubAggStatsDiscontinuityTime.
