DESCRIPTION
|
|
"This MIB module defines a set of objects for monitoring
|
|
and configuring RObust Header Compression (ROHC).
|
|
The objects are specific to ROHC RTP (profile 0x0001),
|
|
ROHC UDP (profile 0x0002), and ROHC ESP (profile 0x0003)
|
|
defined in RFC 3095 and for the ROHC LLA profile (profile
|
|
0x0005) defined in RFC 3242.

DESCRIPTION

"This object is only applicable to preferred packet

sizes of compressor contexts using the LLA profile.

When retrieved, it will indicate whether the packet

size is preferred for NHP only, for RHP only, or
|
|
for both of them.
|
|
|
|
The value of this object is only valid for LLA profiles,

|
i.e., if the corresponding rohcProfile has a value of

|
0x0005. If the corresponding rohcProfile has a value
|
|
other than 0x0005, then this object MUST NOT be
