Claim Text:
1. A method for generating a message integrity check for a data transmission between a plurality of nodes of a cluster, the method comprising: generating a single remote procedure call (RPC) data structure at a source node of the cluster to transmit data of the data transmission, wherein each node comprises a memory and processor and wherein requests and responses between the nodes include RPC data structures; computing one or more block checksums from the data of the data transmission to be included in the single RPC data structure; generating the message integrity check using a hash value of the one or more block checksums; appending the message integrity check to the single RPC data structure, wherein the single RPC data structure comprises a control portion maintaining the one or more block checksums and a message integrity section maintaining the message integrity check; and transmitting, over a computer network, the single RPC data structure, wherein the control portion of the single RPC data structure comprises an operation to perform a second message integrity check using the message integrity check appended to the single RPC data structure.
