PacketMeterBase

simple module

This is a base module for various packet meter modules. Derived modules must implement a single meterPacket() function which meters the flow of and attaches the required tags.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Known subclasses

Name	Type	Description
EligibilityTimeMeter	simple module	This module is a packet meter which measures the packet flow that is passing through and optionally attaches an EligibilityTimeTag to the packets. The tag contains the calculated simulation time when the packet becomes eligibile for transmission according to the asynchronous shaper algorithm.
ExponentialRateMeter	simple module	This module attaches a RateTag to each packet specifying the datarate and packetrate of the received stream of packets. The algorithm takes older packets into account with an exponentially decreasing weight.
MultiTokenBucketMeter	simple module	This module labels packets according to the first token bucket that contains the required number of tokens. If no such token bucket is found then the default label is attached to the packet.
SlidingWindowRateMeter	simple module	This module attaches a RateTag to each packet specifying the datarate and packetrate of the received stream of packets. The algorithm takes packets into account only in the given time window.
TokenBucketMeter	simple module	This module labels each packet if the token bucket contains enough tokens for the packet that is passing through. The amount of required tokens is equal to the packet length in bits and is subtracted from the number of stored tokens. New tokens are generated with the provided constant rate and they may also be added by other modules.

Extends

Name	Type	Description
PacketFlowBase	simple module	This is a base module for various packet flow modules. A packet flow module passes or streams all pushed or pulled packets after processing them from its input to its output.
