Overview and History of the TCP/IP Internet Standard Management Framework and Simple Network Management Protocol (SNMP)
(Page 3 of 3)
Further Development of SNMP and the Problem of SNMP Variations
The description above provides the
history of how the first version of SNMP was developed, leading to the
publishing of the first Internet Standard Management Framework in 1988;
this is now called SNMP version 1 (SNMPv1). This initial version
of SNMP achieved widespread acceptance, and it is still probably the
most common version of SNMP.
Much of the history of SNMP since
that time has been a rather confusing “standards nightmare”.
SNMPv1 had a number of weaknesses, particularly in the area of security.
For this reason, shortly after SNMPv1 was done, work began on a new
version of SNMP. Unfortunately, this effort became a quagmire, with
many competing variations of SNMPv2 being created. After many years
of confusion, none of the SNMPv2 variants achieved significant success.
Recently, a third version of the
SNMP Framework and Protocol has been published, which adds new features
and “reunites” SNMP back under a single universal protocol
again. The topics on SNMP
versions and SNMP
standards later in this section further
explore the history of SNMP since 1988; they can be considered a continuation
of this topic, as they help clarify the very confusing story behind
SNMP versions over the last decade and a half.
This overview may have put more questions
in your mind about the Internet Standard Management Framework and SNMP
than it answered. This is part of why I said this stuff isn't really
that simple. J
The next two topics in this section provide more information about the
Framework and its components, and what those components do, so you can
understand better what the Framework is all about.
