AggregateIPAddrPair
AggregateIPAddrPair — Click element; sets aggregate annotation based on IP source/destination address pair
AggregateIPAddrPair(KEYWORDS)
Ports: 1 input, 1-2 outputs
Processing: agnostic, but output 1 is push
Drivers: userlevel
AggregateIPAddrPair sets the aggregate annotation on every passing packet to a flow number based on its IP address pair. Packets with the same source-destination address pair are assigned the same aggregate number, as are reply packets (with source and destination addresses switched). The paint annotation is set to 0 or 1 to indicate which direction the packet was headed.
Flow numbers are assigned sequentially, starting from 1. Different flows get different numbers. Paint annotations are set to 0 or 1, depending on whether packets are on the forward or reverse subflow. (The first packet seen on each flow gets paint color 0; reply packets get paint color 1.)
Keywords are:
- TIMEOUT — The timeout for active address pairs, in seconds. Default is no timeout (address pairs never expire). If a timeout is specified, then information about an address pair is forgotten after that timeout passes; if the address pair occurs again later, it will get a new aggregate annotation.
- REAP — The garbage collection interval. Default is 20 minutes of packet time.
AggregateIPAddrPair is an AggregateNotifier, so AggregateListeners can request notifications when new aggregates are created and old ones are deleted.
- clear (write-only) — Clears all flow information. Future packets will get new aggregate annotation values.
