Socket transferring for HPC networks using kernel tracing

A computer program product for building socket transferring between containers in cloud-native environments, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:

• probe a connection-relevant system call event to collect and filter data at a router and handled by server and client coordinators;
• and
• create a mirror call at a host namespace with a dummy server and dummy client by:
• creating the dummy server with mirror listening parameters;
• sending a server host address mapping to overlay the server host address to the client coordinator in an overlay process injected with a file description call;
• and
• creating and connecting the dummy client to return a client host address to the server coordinator such that a file descriptor is transferred to a forwarder.

A system for building socket transferring between containers in cloud-native environments, the system comprising:

• a server implementing a server process;
• and
• a client host communicating with the server, the client host implementing a client process, wherein system calls are transmitted from the server to the client host to:
• probe a connection-relevant system call event to collect and filter data at a router and handled by server and client coordinators;
• and
• create a mirror call at a host namespace with a dummy server and dummy client by:
• creating the dummy server with mirror listening parameters;
• sending a server host address mapping to overlay the server host address to the client coordinator in an overlay process injected with a file description call;
• and
• creating and connecting the dummy client to return a client host address to the server coordinator such that a file descriptor is transferred to a forwarder.
