byteblowerll.byteblower.LatencyDistributionMobile

class byteblowerll.byteblower.LatencyDistributionMobile(*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 WirelessEndpoint, using WirelessEndpoint.RxLatencyDistributionAdd()

This packet processor processes frames received on the ByteBlower interface where its parent WirelessEndpoint 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.MeetingPointAdd('byteblower-1.lab.byteblower.com')
wireless_endpoint = server.DeviceGet('aa-89bb54-c04')
trigger = wireless_endpoint.RxLatencyDistributionAdd()
# Do the rest of the test
# ...
result = trigger.ResultGet()
# parse the results
# ...
wireless_endpoint.RxLatencyDistributionRemove(trigger)
