DESCRIPTION
"This MIB module defines a set of basic objects for
monitoring and configuring robust header compression.
The module covers information about running instances
of ROHC (compressors or decompressors) at IP interfaces.
Information about compressor contexts and decompressor
contexts has different structure for different profiles.
Therefore it is not provided by this MIB module, but by
individual modules for different profiles.
Copyright (C) The Internet Society (2004). The
initial version of this MIB module was published
in RFC 3816. For full legal notices see the RFC
itself or see:

The value of this object may be set in order to increase or
reduce the remaining time that the row may exist. Setting
the value to 0 will destroy this entry as soon as the

MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This object indicates the compression ratio concerning the
headers of the last 16 packets passing this context or
concerning the headers of all packets passing this context
if they are less than 16, so far. The compression is
computed over all bytes of all headers that are subject to
compression for the used profile."
::= { rohcContextEntry 20 }
rohcContextLastPacketsMeanSize OBJECT-TYPE
SYNTAX Unsigned32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This object indicates the mean compressed packet size
concerning the last 16 packets passing this context or
concerning all packets passing this context if they are
less than 16, so far. The packet size includes the IP
header and payload but excludes all lower layer headers.
The mean value is given in byte rounded to the next
integer value."

rohcContextLastHeadersMeanSize OBJECT-TYPE
SYNTAX Unsigned32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This object indicates the mean compressed packet header size
concerning the last 16 packets passing this context or
concerning all packets passing this context if they are
less than 16, so far. The packet header size is the sum of
the size of all headers of a packet that are subject to
compression for the used profile. The mean value is given
in byte rounded to the next integer value."
