5.6.  The TCP Group

   Implementation of the TCP group is mandatory for all systems that
   implement the TCP.

   Note that instances of object types that represent information about
   a particular TCP connection are transient; they persist only as long
   as the connection in question.


          OBJECT:
          -------
               tcpRtoAlgorithm { tcp 1 }

          Syntax:
               INTEGER {

                    constant(2), -- a constant rto
                    rsre(3),     -- MIL-STD-1778, Appendix B
                    vanj(4)      -- Van Jacobson's algorithm [11]
               }

          Definition:
               The algorithm used to determine the timeout value used
               for retransmitting unacknowledged octets.

          Definition:
               The minimum value permitted by a TCP implementation for
               the retransmission timeout, measured in milliseconds.
               More refined semantics for objects of this type depend
               upon the algorithm used to determine the retransmission
               timeout.  In particular, when the timeout algorithm is

5.9.  The Transmission Group

   Based on the transmission media underlying each interface on a
   system, the corresponding portion of the Transmission group is
   mandatory for that system.

   When Internet-standard definitions for managing transmission media
   are defined, the transmission group is used to provide a prefix for
   the names of those objects.

   Typically, such definitions reside in the experimental portion of the
   MIB until they are "proven", then as a part of the Internet
   standardization process, the definitions are accordingly elevated and
   a new object identifier, under the transmission group is defined.  By
   convention, the name assigned is:

               type OBJECT IDENTIFIER    ::= { transmission number }

   where "type" is the symbolic value used for the media in the ifType
   column of the ifTable object, and "number" is the actual integer
   value corresponding to the symbol.

5.10.  The SNMP Group

   Implementation of the SNMP group is mandatory for all systems which
   support an SNMP protocol entity. Some of the objects defined below

Top       Page 84 
   will be zero-valued in those SNMP implementations that are optimized
   to support only those functions specific to either a management agent
   or a management client.
