             Summary: Checksum all communication between Cassandra nodes
                 Key: CASSANDRA-8117
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8117
             Project: Cassandra
          Issue Type: Improvement
            Reporter: sankalp kohli


We have seen corruption in Gossip due to corruption happening in the n/w card 
between main memory which is ECC protected and TCP checksum. Same corruption 
can happen to other data flowing b/w machines. We should add checksum to all 
communication b/w machines in the application. 

A different JIRA could be to add checksums from the client driver for writes 
and back to the driver for reads.
