A proprietary network protocol is one that does not comply to any open standards. The intent of a proprietary protocol is to limit communication only to nodes that implement a specific application. NetBIOS is an example of a proprietary network protocol that is only applicable to Microsoft Windows hosts. The opposite of a proprietary protocol is an open standard, which can be utilized by any application. An example of an open standard is TCP/IP, the standard protocol of the internet.
