byteblowerll.byteblower.LatencyDistribution¶

class byteblowerll.byteblower.LatencyDistribution(*args, **kwargs)¶

Receive-side packet processor which calculates distribution of latency on the incoming frames, matching a filter.

This latency distribution calculation is always active and starts processing frames as soon as it is created. Processing continues until the packet processor is destructed.

The transmit time stamp of a packet is obtained from a time tag in the frame. This tag is configured on the FrameTag.Tx, which can be obtained via :meth:.Frame.FrameTagTimeGet`.

..note:: The initial (empty) filter string accepts all incoming frames. See FilterSet() for filtering information.

A latency distribution object can be created via a ByteBlowerPort, using ByteBlowerPort.RxLatencyDistributionAdd()

This packet processor processes frames received on the ByteBlower interface where its parent ByteBlowerPort is located.

Example

Receive all frames on “trunk-1-45” of some server, matching UDP source or destination port 49523.

from byteblowerll.byteblower import ByteBlower
server = ByteBlower.ServerAdd('byteblower-1.lab.byteblower.com')
# TODO

__init__(*args, **kwargs)¶: Initialize self. See help(type(self)) for accurate signature.
