Abstract
A method for handling transmission control protocol (TCP) data between networked computer nodes during blackout periods associated with live kernel updating is provided. The method includes initiating a live kernel update on a first node, transmitting, prior to performing a network blocking procedure associated with the live kernel update, a zero window update to one or more peer nodes, generating a surrogate partition associated with the first node, copying network states from an original partition associated with the first node to the surrogate partition, restoring the network states on the surrogate partition, and transmitting another window update to the one or more peer nodes.
