preload a shared library into the transmission control protocol client application and the transmission control protocol server application when starting the transmission control protocol client application and the transmission control protocol server application,

wherein the shared library comprises the one or more customized socket application programming interface functions.

4 . The apparatus of claim 1 , wherein the one or more customized socket application programming interface functions are comprised in a shared library integrated into the transmission control protocol client application and the transmission control protocol server application prior to starting the transmission control protocol client application and the transmission control protocol server application.

5 . The apparatus of claim 1 , wherein the one or more customized socket application programming interface functions are comprised in a kernel of an operating system of the apparatus.

6 . The apparatus of claim 5 , wherein the replacing comprises using a loadable kernel module to intercept and redirect one or more system calls from the one or more socket application programming interface functions to the one or more customized socket application programming interface functions.

7 . The apparatus of claim 5 , wherein the replacing comprises modifying the kernel of the operating system of the apparatus to direct one or more calls to the one or more customized socket application programming interface functions.

8 . The apparatus of claim 5 , caused to:

add, within the kernel of the operating system of the apparatus, a transport mechanism for utilizing the one or more shared memory channels for the communication between the transmission control protocol client application and the transmission control protocol server application,

wherein the one or more customized socket application programming interface functions are configured to support the transport mechanism added within the kernel.

9 . The apparatus of claim 1 , wherein the one or more customized socket application programming interface functions are further configured to create the one or more transmission control protocol sockets.

10 . The apparatus of claim 9 , wherein the apparatus is caused to create the one or more shared memory channels based on a type and an address of the one or more transmission control protocol sockets.

11 . The apparatus of claim 9 , wherein the one or more customized socket application programming interface functions are further configured to:

associate the one or more transmission control protocol sockets with a context indicating a possibility for using the one or more shared memory channels as an alternative to the one or more transmission control protocol sockets, and

start the at least one of the transmission control protocol client application or the transmission control protocol server application based on the context indicating the possibility for using the one or more shared memory channels, such that the at least one of the transmission control protocol client application or the transmission control protocol server application is configured to support the one or more shared memory channels for the communication between the transmission control protocol client application and the transmission control protocol server application.

12 . The apparatus of claim 11 , caused to:

perform one or more further socket application programming interface calls associated with one or more socket file descriptors;

determine whether the one or more socket file descriptors are associated with the context indicating the possibility for using the one or more shared memory channels; and

based at least on determining that the one or more socket file descriptors are associated with the context, utilize the one or more shared memory channels for the communication between the transmission control protocol client application and the transmission control protocol server application according to the one or more further socket application programming interface calls.

13 . The apparatus of claim 12 , wherein the utilization of the one or more shared memory channels for the communication comprises at least one of:

writing, by the transmission control protocol client application or the transmission control protocol server application, one or more messages in the one or more shared memory channels, or

reading, by the transmission control protocol server application or the transmission control protocol client application, the one or more messages from the one or more shared memory channels.

14 . The apparatus of claim 1 , caused to:

determine whether the one or more shared memory channels are available for the communication; and

based at least on determining that the one or more shared memory channels are available for the communication, utilize the one or more shared memory channels for the communication between the transmission control protocol client application and the transmission control protocol server application.

15 . The apparatus of claim 1 , caused to:

determine whether the transmission control protocol client application and the transmission control protocol server application are capable of utilizing the one or more shared memory channels; and
