DESCRIPTION
"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."
REVISION "200010020000Z" -- 2 October 2000

Published as RFC 2959."
::= { mib-2 87 }
InterfaceIndex ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"A unique value, greater than zero, for each interface
or interface sub-layer in the managed system. It is
recommended that values are assigned contiguously
starting from 1. The value for each interface sub-
layer must remain constant at least from one re-
initialization of the entity's network management
system to the next re-initialization."
SYNTAX Integer32
Utf8String ::= TEXTUAL-CONVENTION
DISPLAY-HINT "1024a"
STATUS current
DESCRIPTION
"To facilitate internationalization, this TC
represents information taken from the ISO/IEC IS
10646-1 character set, encoded as an octet string
using the UTF-8 character encoding scheme described
in RFC 2044 [10]. For strings in 7-bit US-ASCII,
there is no impact since the UTF-8 representation
is identical to the US-ASCII encoding."

DESCRIPTION
"This object is used to assign values to rtpSessionIndex
as described in 'Textual Conventions for SMIv2'. For an RTP
system that supports the creation of rows, the network manager
would read the object, and then write the value back in
the Set that creates a new instance of rtpSessionEntry. If
the Set fails with the code 'inconsistentValue,' then the
process must be repeated; If the Set succeeds, then the object
is incremented, and the new instance is created according to
the manager's directions. However, if the RTP agent is not
acting as a monitor, only the RTP agent may create conceptual
rows in the RTP session table."

DESCRIPTION
"Data in rtpSessionTable uniquely identify an RTP session. A
host RTP agent MUST create a read-only row for each session to
which packets are being sent or received. Rows MUST be created
by the RTP Agent at the start of a session when one or more
senders or receivers are observed. Rows created by an RTP agent
MUST be deleted when the session is over and there are no
rtpRcvrEntry and no rtpSenderEntry for this session. An RTP
session SHOULD be monitored to create management information on
all RTP streams being sent or received when the
rtpSessionMonitor has the TruthValue of 'true(1)'. An RTP
monitor SHOULD permit row creation with the side effect of
causing the RTP System to join the multicast session for the
purposes of gathering management information (additional
conceptual rows are created in the rtpRcvrTable and
rtpSenderTable). Thus, rtpSessionTable rows SHOULD be created
for RTP session monitoring purposes. Rows created by a
management application SHOULD be deleted via SNMP operations by
management applications. Rows created by management operations
are deleted by management operations by setting
rtpSessionRowStatus to 'destroy(6)'."
