Abstract

The Common Object Request Broker Architecture (CORBA) (1) specifies the architecture by which instances in a heterogeneous environment can communicate requests (that is, invoke methods) with each other regardless of whether they are local or remote. Recently, the increasing popularity of the CORBA pushed many people to write mappings between the "CMIP" and "SNMP" (2,3) protocols and CORBA based on the assumption that CORBA will become the network management standard of the future and that everybody will use it instead of CMIP and SNMP.

Multidomain Network Management Using Common Object Request Broker
Architecture

      The Common Object Request Broker Architecture (CORBA) (1)
specifies the architecture by which instances in a heterogeneous
environment can communicate requests (that is, invoke methods) with
each other regardless of whether they are local or remote.  Recently,
the increasing popularity of the CORBA pushed many people to write
mappings between the "CMIP" and "SNMP" (2,3) protocols and CORBA
based on the assumption that CORBA will become the network management
standard of the future and that everybody will use it instead of CMIP
and SNMP.

      Disclosed is a technique which allows management of CMIP and
SNMP network resources through CORBA.  Relevant characteristics of
this technique are:  full support of the CMIP and SNMP protocols, no
limitations on the complexity of the ASN.1 (4) attribute syntaxes,
light, extensible, string-syntax based.  The goal of this work is to
allow management of CMIP and SNMP resources through CORBA easily.

      To avoid the burden of mapping ASN.1 datatype to CORBA, every
ASN.1 datatype is represented using a CORBA string according to the
mapping defined in document (5) without mapping it to a CORBA
datatype closer to the original ASN.1 type.  This mapping allows
ASN.1 datatype to be fully supported and reduces significantly the
complexity of the whole system since each ASN.1 datatype is
represented with a string; hence, there is no need to define new
CORBA types when new ASN.1 types have to be supported and to modify
the application in order to support new types of management
applications which deal only with strings that are natively supported
by programming languages.

      CORBA object interfaces, defined using the Interface Definition
Language (IDL), represent generic CMIP and SNMP objects.  The
interface DSOMInformation, derived from SOMObject, contains the
information relative to the request and to the response(s).
DSOMSNMPObj and DSOMCMIPObj interfaces, derived from DSOMInformation,
implement some high ...
