| UNO Remote Protocol (URP). A binary protocol. | |
| UNO provides a protocol called the UNO Remote Protocol (URP) that provides | |
| a bridge between UNO environments. This bridge allows processes and objects | |
| to send method calls and to receive return values. UNO objects in different | |
| environments are connected by way of this interprocess bridge. The underlying | |
| connection is made through a socket or pipe. Remote UNO objects are connected | |
| by means of TCP/IP using the high-level protocol of the URP. | |
