This is an implementation of a connection between server (or many servers) to one client under "infiniband" connection. Click for more information.
The API enables the client to send messages or files to the server and to get it back later when needed. Depending on the amount of servers which are available, the messages or the files will be evenly saved among the servers. (For this to happen, one of the servers has to handle the task of distributing the files(act like a "load balancer"). it does not have to be a different server)
Inside "http-server" there is an implementation example of http-server using this functionality.
