TAILIEUCHUNG - Internetworking with TCP/IP- P61

Internetworking with TCP/IP- P61: TCP/IP has accommodated change well. The basic technology has survived nearly two decades of exponential growth and the associated increases in traffic. The protocols have worked over new high-speed network technologies, and the design has handled applications that could not be imagined in the original design. Of course, the entire protocol suite has not remained static. New protocols have been deployed, and new techniques have been developed to adapt existing protocols to new network technologies | Sec. The Structure Of Management Information 559 integer in the range of 0 to 232- 1 and specifies that they are the terms used to define MIB variables. More important the rules in the SMI describe how the MIB refers to tables of values . the IP routing table . Formal Definitions Using The SMI standard specifies that all MIB variables must be defined and referenced using ISO s Abstract Syntax Notation 1 j . is a formal language that has two main features a notation used in documents that humans read and a compact encoded representation of the same information used in communication protocols. In both cases the precise formal notation removes any possible ambiguities from both the representation and meaning. For example instead of saying that a variable contains an integer value a protocol designer who uses ASN. 1 must state the exact form and range of numeric values. Such precision is especially important when implementations include heterogeneous computers that do not all use the same representations for data items. Besides keeping standards documents unambiguous also helps simplify the implementation of network management protocols and guarantees interoperability. It defines precisely how to encode both names and data items in a message. Thus once the documentation of a MIB has been expressed using the human readable form can be translated directly and mechanically into the encoded form used in messages. In summary The TCP IP network management protocols use a formal notation called to define names and types for variables in the management information base. The precise notation makes the form and contents of variables unambiguous. Structure And Representation Of MIB Object Names We said that specifies how to represent both data items and names. However understanding the names used for MIB variables requires us to know about the underlying namespace. Names used for MIB variables are taken from the object .
