Broadcast Source code
The customized SW for KM3net demonstrator is already in the repository.
• There is a Manual to start playing with it easily.
• Scripts to compile the code and configure the switch.
• Waiting for feedback from KM3net community

Pause Frame.The entire pause frame is finished.
The TX is done.
The Rx is done (almost). • The mechanism has been tested.• A couple of minor suggestions from Peter are going to be
done. They will be finished before the end of the week.

Pause Frame.Tx Pause frame at the on-shore station.
1- DOM 1 is sending too much traffic.2- The pause frame is triggered by the Rx port of the WRS1.3- The pause frame arrives at all the DOMs but just DOM1 will accept the request. The PF uses unicast address.

Pause Frame.Rx Pause frame at the on-shore station
1- The BC Switch is sending to much traffic through the SC link.2- A DOM reception buffer exceeds the threshold . A pause frame is transmitted to the on-shore station.3- The PF arrives at the BC switch which halts the whole BC link for a limited period.

7S tasks for KM3NetKM3Net topology requires: Gateware/Firmware modifications:
• Broadcast implementation (TX to DOMs) .• Pause frame protocol.
KM3Net demonstrator 3 network levels: o 2 SPECs as DOMs o 3 WR switches as ShoreStation network
This is our last signed task, so that we wait for your feedback and validation to upload and close the system.
