Development and Information Library of SNMP protocol (1)

SNMP has become the most widely used Network Management Protocol. So how does it develop step by step? Here we will briefly describe the relevant features, as well as its management information library. From the descriptions in this article, we will be able to better understand.

SNMP protocol development

SNMP is the most widely used Network Management Protocol in TCP/IP networks. In May 1990, RFC1157 defined SNMP (simplenetworkmanagementprotocol) the first version of SNMPv1. RFC1157, together with another file RFC1155 on information management, provides a system method for monitoring and managing computer networks. Therefore, SNMP has been widely used, and become the de facto standard for network management ｡

The SNMP protocol developed rapidly in Early 1990s S and exposed obvious shortcomings. For example, it is difficult to implement a large amount of data transmission, lack of Authentication and encryption) therefore, SNMPv2 was released in 1993 and has the following features:

Supports distributed network management

Extended Data Type

It can achieve simultaneous transmission of a large amount of data, improving efficiency and performance

Enriched fault handling capabilities

Added the set processing function.

Enhanced Data Definition Language
