Abstract
An embodiment of a method of restoring a communication state of a process includes creating a new socket for a socket saved as part of a checkpoint of the communication state. The new socket is initialized with an adjusted transmission control protocol state saved as part of the checkpoint. The adjusted transmission control protocol state indicates that a send buffer and a receive buffer are empty. Send data saved as part of the checkpoint is written into the new socket. Receive data saved as part of the checkpoint is written into a restart buffer. While at least a portion of the receive data remains in the restart buffer, a socket read system call for the new socket is redirected to read the receive data that remains in the restart buffer.
