 The network has been designed to exploit the worst case of the Ethernet protocol. Namely the spanning tree is constructed such that the the nodes are at the bottom of different branches of the tree. As such, the direct link between switches 12 and 13 is disabled, and the packets must traverse the entire ring.

 Due to this, the Ethernet protocol performs very badly here, requiring 26 frames in each direction for the UDP packet and the ARP Response packet - giving a total of 52 unicast UDP packets, and 52 unicast ARP packets, combining to make a total of 104 unicast frames.

 Using broadcast in a mesh network is problematic for MOOSE, as it utilises Reverse Path Forwarding to prevent broadcast storms, whereas Ethernet uses the Rapid Spanning Tree Protocol. s such, each broadcast packet is sent to the next switch, before it is culled in MOOSE, while in Ethernet, it doesn't need to send it any further as it knows the entire topology.
