Title: Full flow retrieval optimized packet capture

Patent ·
OSTI ID:1525041

A packet capture system may copy packets from an interface to a bucket. When the bucket is full of packets, a new bucket for incoming packets may be started, and the full bucket may be indexed. During the indexing, each packet may be sorted in the bucket by flow, and each flow may be indexed. Once indexing is complete, the packets are written to a flow ordered FCAP file and the indexes are written to disk. The flow ordered nature of the FCAP file combined with the indices and their associated search algorithms allow for rapid retrieval of captured flows.
