Porting an Application

An application based on either TCP or UDP can run in binary-compatibility mode. For some applications you only recompile and relink all source files. This may be true of applications that use simple RPC calls and use no socket or TCP or UDP specifics.

Some editing and new code may be needed if an application depends on socket semantics or features specific to TCP or UDP. Examples use the format of host addresses or rely on the Berkeley UNIX concept of privileged ports.

Applications that are dependent on the internals of the library or the socket implementation, or depend on specific transport addressing probably require more effort to port and may require substantial modification.
