Method and system to transfer data utilizing cut-through sockets

A method to exchange information between computer applications, the method comprising:

• receiving, at an offload stack hosted on a device comprising one or more processors, a message from a source operating system to a destination operating system, the source operating system and the destination operating system being distinct network nodes and having a shared memory, the shared memory of the source operating system and the destination operating system comprising a memory page to which data from the source operating system has been written, the offload stack being hosted by a third operating system separate from the source operating system and the destination operating system, the message from the source operating system comprising a request to transfer source data from the source operating system to the destination operating system;
• determining by the offload stack, that the source operating system and the destination operating system are both hosted on the device;
• transferring the message to the destination operating system such that a network layer of the offload stack is bypassed in response to the determination that the source operating system and the destination operating system are both hosted on the device, wherein transferring the message such that the network layer is bypassed comprises transferring a pointer to the memory page from the source operating system to the destination operating system;
• and
• transferring, by the offload stack, the source data from the source operating system to the destination operating system by transferring ownership of memory pages storing the source data.

A non-transitory machine-readable storage medium having instructions which, when executed by a machine, cause the machine to:

• receive, at an offload stack hosted on a device, a message from a source operating system to a destination operating system, the source operating system and the destination operating system being distinct network nodes and having a shared memory, the shared memory of the source operating system and the destination operating system comprising a memory page to which data from the source operating system has been written, the offload stack being hosted by a third operating system separate from the source operating system and the destination operating system, the message from the source operating system comprising a request to transfer source data from the source operating system to the destination operating system;
• determine, at the offload stack, that the source operating system and the destination operating system are both hosted on the device;
• transfer the message to the destination operating system such that a network layer of the offload stack is bypassed in response to the determination that the source operating system and the destination operating system are both hosted on the device, wherein transferring the message such that the network layer is bypassed comprises transferring a pointer to the memory page from the source operating system to the destination operating system;
• and
• transfer, by the offload stack, the source data from the source operating system to the destination operating system by transferring ownership of memory pages storing the source data.

A system to exchange information between computer applications, the system comprising:

• means for receiving, at an offload stack hosted on a device, a message from a source operating system to a destination operating system, the source operating system and the destination operating system being distinct network nodes and having a shared memory, the shared memory of the source operating system and the destination operating system comprising a memory page to which data from the source operating system has been written, the offload stack being hosted by a third operating system separate from the source operating system and the destination operating system, the message from the source operating system comprising a request to transfer source data from the source operating system to the destination operating system;
• means for determining, at the offload stack, that the source operating system and the destination operating system are both hosted on the device;
• and
• means for transferring the message to the destination operating system such that a network layer of the offload stack is bypassed in response to the determination that the source operating system and the destination operating system are both hosted on the device, wherein the means for transferring the message comprises means for transferring a pointer to the memory page from the source operating system to the destination operating system;
• and
• means for transferring, at the offload stack, the source data from the source operating system to the destination operating system by transferring ownership of memory pages storing the source data.
