16.4. Integration of IPC with communications
16.4.1. IPC above sockets
A socket is the operating system provided interface to communications services. In this section we see the system calls that any IPC support package, for example java.net, makes on behalf of the distributed system programmer. An example of Java socket programming is given in Section 16.5. In later sections we see how higher levels of abstraction are provided for the programmer.
The basic concepts at the operating system interface for integrating IPC with communications software are:
socket: an endpoint of communication;
domain: within which sockets are named and communication takes place. A socket operates in a single domain and the address format of the socket depends on that ...
