RTP-MIB
64 objects
The managed objects of RTP systems. The MIB is structured around three types of information. 1. General information about RTP sessions such as the session address. 2. Information about RTP streams being sent to an RTP session by a particular sender. 3. Information about RTP streams received on an RTP session by a particular receiver from a particular sender. There are two types of RTP Systems, RTP hosts and RTP monitors. As described below, certain objects are unique to a particular type of RTP System. An RTP host may also function as an RTP monitor. Refer to RFC 1889, 'RTP: A Transport Protocol for Real-Time Applications,' section 3.0, for definitions.
