sprint2

The first sprint has passed its time for the second sprint.

sprint results 1

Using the method of sending a whole bunch of message at the same time and timing how long it takes before they get back the following milliseconds per message have been measured using the protocols isc capabilities( dont understand what is actually being measured? look at the bandwidth chapter in RoundTrip).

ISC measurements bandwidth
Language: python3
protocol ms/msg
MQTT 6.5
ZMQ 7.3
DDS under construction

If the processes communicate in an interprocess way the following times are measured:

IPC measurements bandwidth
Language: python3
protocol ms/msg
MQTT 9.5
ZMQ 0.4
DDS under construction
