Aguri is an aggregation-based traffic profiler targeted for near real-time,
|
|
long-term, and wide-area traffic monitoring. Aguri adapts itself to spatial
|
|
traffic distribution by aggregating small volume flows into aggregates, and
|
|
achieves temporal aggregation by creating a summary of summaries applying the
|
|
same algorithm to its outputs. A set of scripts are used for archiving and
|
|
visualizing summaries in different time scales. Aguri does not need a
|
|
predefined rule set and is capable of detecting an unexpected increase of
|
|
unknown protocols or DoS attacks, which considerably simplifies the task of
|
|
network monitoring.
|
|
|
|
Aguri produces four separate profiles for source addresses, destination
|
|
addresses, source protocols and destination protocols. IP addresses are
|
|
designed to be hierarchical and aggregatable so that it is natural to apply
|
|
aggregation. Both IPv4 and IPv6 are supported in address profiles. Although
|
|
protocol numbers are not hierarchical, the same technique can be used to
|
|
identify port ranges. We concatenate the IP version, the protocol number and
|
|
the TCP/UDP port number to create a 32-bit key for a protocol profile.
