Abstract
Transaction and session processing of packets within a network monitoring system may be distributed among tightly-coupled processing elements by marking each received packet with a time-ordering sequence reference. The marked packets are distributed among processing elements by any suitable process for transaction processing by the respective processing element to produce transaction metadata. Where a session-owning one of the processing elements has indicated ownership of the session to the remaining processing elements, the transaction-processed packet and transaction metadata are forwarded to the session owner. The session owner aggregates transaction-processed packets for the session, time-orders the aggregated packets, and performs session processing on the aggregated, time-ordered transaction-processed packets to generate session metadata with the benefit of context information. Where the session owner for a transaction-processed packet has not previously been indicated, the transaction-processed packet and transaction metadata are forwarded to an ordering authority of last resort, which assigns ownership of the session.
