DESCRIPTION
"This module defines a MIB for Round Trip Time (RTT) monitoring of a list of targets, using a variety of protocols.
The table structure overview is a follows (t: indicates a table, at: indicates an augmented table, and it: indicates table with the same indices/control as parent table):

DEFINITIONS:
conceptual RTT control row - This is a row in the 'Overall Control Group'. This row is indexed via the rttMonCtrlAdminIndex object. This row is spread across multiple real tables in the 'Overall Control Group'.
probe - This is the entity that executes via a conceptual RTT control row and populates a conceptual statistics row and a conceptual history row.
Rtt operation - This is a single operation performed by a probe. This operation can be a single Rtt attempt/completion or a group of Rtt attempts/completions that produce one operation table entry.
ARR Protocol Definition: The format of the RTT Asymmetric Request/Responses (ARR) protocol is as follows:
The ARR Header (total of 12 octets):
4 octet -> eyecatcher: 'WxYz'
1 octet -> version : 0x01 - protocol version
1 octet -> command : 0x01 - logoff request
0x02 - echo request
0x03 - echo response
0x04 - software version request
0x05 - software version response
2 octet -> sequence number (Network Byte Order)
4 octet -> response data size (Network Byte Order)
The ARR Data:
n octets -> request/response data: 'AB..ZAB..ZAB..'
For software version request/response the protocol version octet will contain the version number of the responder. Thus the sequence number, etc will not be included.
For snaLU0EchoAppl and snaLU2EchoAppl all character fields will be in EBCDIC.
The response data should be appended to the origin request data. This allows data verification to check the data that flows in both directions. If the response data size is smaller than the request data size the original request data will be truncated.
An example would be:
Request: / Response:
'WxYz' / 'WxYz'
0x01 / 0x01
0x02 / 0x03
0x0001 / 0x0001
0x00000008 / 0x00000008
'ABCDEF' / 'ABCDEFGH'
NOTE: We requested 8 bytes in the response and the response had 8 bytes. The size of the request data has no correlation to the size of the response data.
NOTE: For native RTT request/response (i.e. ipIcmpecho) operations both the 'Header' and 'Data' will be included. Only the 'sequence number' in the Header will be valid.
NOTE: For non-connection oriented protocol the initial RTT request/response operation will be preceded with an RTT request/response operation to the target address to force path exploration and to prove connectivity. The History collection table will contain these responses, but the Statistics capture table will omit them to prevent skewed results."
