behzad nouri 3b87aa9227 reverts wide fanout in broadcast when the root node is down (#26359) ... A change included in https://github.com/solana-labs/solana/pull/20480 was that when the root node in turbine broadcast tree is down, the leader will broadcast the shred to all nodes in the first layer. The intention was to mitigate the impact of dead nodes on shreds propagation, because if the root node is down, then the entire cluster will miss out the shred. On the other hand, if x% of stake is down, this will cause 200*x% + 1 packets/shreds ratio at the broadcast stage which might contribute to line-rate saturation and packet drop. To avoid this bandwidth saturation issue, this commit reverts that logic and always broadcasts shreds from the leader only to the root node. As before we rely on erasure codes to recover shreds lost due to staked nodes being offline.		2022-08-16 19:40:06 +00:00
