1. A method, comprising:

  • collecting and storing a plurality of transmission events as network event data elements in a plurality of data structures, each transmission event being reported by one or more nodes of a network and stored in compressed form in at least one storage site;

    extracting said plurality of transmission events stored as network event data elements in said plurality of data structures;

    based on a set of predefined network event characteristics and the extracted plurality of transmission events, creating indices which identify data structures and locations of network event data elements within those data structures, wherein each index identifies a data structure and a respective location of a network event data element within that data structure;

    receiving a query that requests particular transmission event information;

    based on the query, accessing the indices to identify a location of at least one network event data element by apportioning said query into multiple partial queries that request the particular transmission event information and sending the multiple partial queries to different storage sites which store said plurality of data structures; and

    in response to the multiple partial queries, receiving query results from the different storage sites and combining the query results to form an analyzable aggregation of transmission event information;

    wherein the query results contain particular transmission events in the compressed form to maximize the amount of data conveyed in each disk cycle.
