ABSTRACT:
In one embodiment, a network architecture includes a plurality of application monitoring modules for monitoring network traffic data in a plurality of network segments. Network monitoring modules include a staging area that receives network traffic data from a packet capture and analysis engine and an indexing area that stores the data in meta-flow tuples with associated measures divided into time interval buckets. Index tables store dimension-based sorted pointers to the storage locations in the data buckets. HyperLock queries collect time aggregated results for measure based operators with respect to a queried dimension. For each value of the queried dimension, the time interval buckets are traversed compiling a partial result that is finally stored in a stack as the time aggregated value. The stored sorted pointers are used to determine the starting location in each bucket with respect to the next value of the queried dimension.
