Class Names, Class Numbers, and Class Types

Expert(s)
Dimitri Papadimitriou
Reference
[RFC3936]
Note
Each class of data object in an RSVP message is identified by a Class
Name and an 8-bit Class Number.  The Class Name is all upper-case.
Within each object class there is an 8-bit Class Type (also known as a
C-Type).  The following lists shows the Class Number and Class Name for
each class, followed by the corresponding Class Types.

In general, the appropriateness of allowing assignments of Class Types
through Expert Review or Vendor Private depends on the semantics of the Class
Number itself.  Thus, any new Class Number definition must specify an
appropriate IANA Considerations policy for assigning additional Class
Type values.

For Class Numbers that pre-date [RFC3936] (specifically, 0, 1, 3-25,
30-37, 42-45, 64, 65, 128-131, 161-165, 192-196, and 207), the
default assignment policy for new Class Types is Standards Action,
unless a Standards Track or Best Current Practice RFC supercedes this.

The EXPLICIT_ROUTE object [RFC3209] carries a variable length sub-
object that is identified by a 7-bit Type field.  Types 0 through 119
are to be assigned by Standards Action.  Types 120 through 123 are to
be assigned by Expert Review.  Types 124 through 127 are to be
reserved for Vendor Private Use.

The RECORD_ROUTE object [RFC3209] carries a variable length sub-
object that is identified by an 8-bit Type field.  Types 0 through
191 are to be assigned by Standards Action.  Types 192 through 251
are to be assigned by Expert Review.  Types 252 through 255 are to be
reserved for Vendor Private Use.

Error Codes and Globally-Defined Error Value Sub-Codes

Expert(s)
Dimitri Papadimitriou
Reference
[RFC3936]
Note
An Error Code is an 8-bit quantity that appears in an ERROR_SPEC
object to broadly define an error condition.  With each Error Code
there may be a 16-bit Error Value that further specifies the cause
of the error.  Error Values may be globally defined, in which case
the sub-code component is assigned by IANA [RFC2205].

Globally defined Error Values are assigned by Standards Action.

The following list extends the basic list of Error Codes and Values that
are defined in [RFC2205].
