RFC1065 - часть 4


For example, the structure of a

given object type might be an INTEGER or OCTET STRING. Although in

general, we should permit any ASN.1 construct to be available for use

in defining the syntax of an object type, this memo purposely

restricts the ASN.1 constructs which may be used. These restrictions

are made solely for the sake of simplicity.

The encoding of an object type is simply how instances of that object

type are represented using the object's type syntax. Implicitly tied

to the notion of an object's syntax and encoding is how the object is

represented when being transmitted on the network. This memo

specifies the use of the basic encoding rules of ASN.1 [6].

It is beyond the scope of this memo to define either the initial MIB

used for network management or the network management protocol. As

mentioned earlier, these tasks are left to the companion memos. This

memo attempts to minimize the restrictions placed upon its companions

so as to maximize generality. However, in some cases, restrictions

have been made (e.g., the syntax which may be used when defining

object types in the MIB) in order to encourage a particular style of

management. Future editions of this memo may remove these

restrictions.

3.1. Names

Names are used to identify managed objects. This memo specifies

names which are hierarchical in nature. The OBJECT IDENTIFIER

concept is used to model this notion. An OBJECT IDENTIFIER can be

used for purposes other than naming managed object types; for

example, each international standard has an OBJECT IDENTIFIER

assigned to it for the purposes of identification. In short, OBJECT

IDENTIFIERs are a means for identifying some object, regardless of

the semantics associated with the object (e.g., a network object, a

standards document, etc.)

Rose & McCloghrie [Page 4]

RFC 1065 SMI August 1988

An OBJECT IDENTIFIER is a sequence of integers which traverse a

global tree. The tree consists of a root connected to a number of

labeled nodes via edges.
