US Patent:

7558290, Jul 7, 2009

Filed:

Dec 16, 2005

Appl. No.:

11/303651

Inventors:

Antonio Nucci - Burlingame CA, US
Su Chen - Somerset NJ, US

Assignee:

Narus, Inc. - Sunnyvale CA

International Classification:

H04J 3/18

US Classification:

370477

Abstract:

An important component of network monitoring is to collect traffic data which is a bottleneck due to large data size. We introduce a new table compression method called “Group Compression” to address this problem. This method uses a small training set to learn the relationship among columns and group them; the result is a “compression plan”. Based on this plan, each group is compressed separately. This method can reduce the compressed size to 60%-70% of the IP flow logs compressed by GZIP.
