Joint Inter-Domain Management
Joint Inter-Domain Management (JIDM) task force, jointly sponsored by X/Open and the Network Management Forum, has defined a mapping between SNMP, CMIP and CORBA. The JIDM specification was adopted as a standard by the Open Group in 2000. The mapping specification is in two parts: the Specification Translation and the Interactive Translation. The Specification Translation spells out translation of the object oriented object models among the network management protocols that allow for data transfer across protocols. The Interactive Translation concerns the dynamic translation of objects in use that allows for the construction of network management software that operates across protocols. The JIDM specification was considered the most significant work to use the CORBA framework in network management mapping. The JIDM specification led to CORBA's further use in specifications in the telecommunications industry, such as the ITU-T GDMO specifications. But the object framework led to p ...

X/Open
X/Open group (also known as the Open Group for Unix Systems and incorporated in 1987 as X/Open Company, Ltd.) was a consortium founded by several European UNIX systems manufacturers in 1984 to identify and promote open standards in the field of information technology. More specifically, the original aim was to define a single specification for operating systems derived from UNIX, to increase the interoperability of applications and reduce the cost of porting software. Its original members were Bull, ICL, Siemens, Olivetti, and Nixdorf—a group sometimes referred to as BISON. Philips and Ericsson joined in 1985, at which point the name X/Open was adopted. The group published its specifications as X/Open Portability Guide, starting with Issue 1 in 1985, and later as ''X/Open CAE Specification''. In 1987, X/Open was incorporated as X/Open Company, Ltd. By March 1988, X/Open grew to 13 members: AT&T, Digital, Hewlett-Packard, Sun Microsystems, Unisys, NCR, Olivetti, Bull, Ericsson ...

Simple Network Management Protocol
Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behaviour. Devices that typically support SNMP include cable modems, routers, switches, servers, workstations, printers, and more. SNMP is widely used in network management for network monitoring. SNMP exposes management data in the form of variables on the managed systems organized in a management information base (MIB) which describe the system status and configuration. These variables can then be remotely queried (and, in some circumstances, manipulated) by managing applications. Three significant versions of SNMP have been developed and deployed. SNMPv1 is the original version of the protocol. More recent versions, SNMPv2c and SNMPv3, feature improvements in performance, flexibility and security. SNMP is a component of the Internet Protocol Suite as defined by the I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Management Interface Protocol
The Common Management Information Protocol (CMIP) is the OSI specified network management protocol. Defined iITU-T Recommendation X.711, ISO/IEC International Standard 9596-1 It provides an implementation for the services defined by the Common Management Information Service (CMIS) specified iITU-T Recommendation X.710, ISO/IEC International Standard 9595 allowing communication between network management applications and management agents. CMIS/CMIP is the network management protocol specified by the ISO/ OSI Network management model and is further defined by the ITU-T in the X.700 series of recommendations. CMIP models management information in terms of managed objects and allows both modification and performing actions on managed objects. Managed objects are described using GDMO (Guidelines for the Definition of Managed Objects), and can be identified by a distinguished name (DN), from the X.500 directory. CMIP also provides good security (support authorization, access co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CORBA
The Common Object Request Broker Architecture (CORBA) is a standard defined by the Object Management Group (OMG) designed to facilitate the communication of systems that are deployed on diverse platforms. CORBA enables collaboration between systems on different operating systems, programming languages, and computing hardware. CORBA uses an object-oriented model although the systems that use the CORBA do not have to be object-oriented. CORBA is an example of the distributed object paradigm. Overview CORBA enables communication between software written in different languages and running on different computers. Implementation details from specific operating systems, programming languages, and hardware platforms are all removed from the responsibility of developers who use CORBA. CORBA normalizes the method-call semantics between application objects residing either in the same address-space (application) or in remote address-spaces (same host, or remote host on a network).

The Open Group
The Open Group is a global consortium that seeks to "enable the achievement of business objectives" by developing "open, vendor-neutral technology standards and certifications." It has over 840 member organizations and provides a number of services, including strategy, management, innovation and research, standards, certification, and test development. It was established in 1996 when X/Open merged with the Open Software Foundation. The Open Group is the certifying body for the UNIX trademark, and publishes the Single UNIX Specification technical standard, which extends the POSIX standards. The Open Group also develops and manages the TOGAF® standard, which is an industry standard enterprise architecture framework. Members The over 840 members include a range of technology vendors and buyers as well as government agencies, including, for example, Capgemini, Fujitsu, HPE, Orbus Software, IBM, Huawei, Philips, the U.S. Department of Defense, and NASA.

Object Oriented
Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code. The data is in the form of fields (often known as attributes or ''properties''), and the code is in the form of procedures (often known as ''methods''). A common feature of objects is that procedures (or methods) are attached to them and can access and modify the object's data fields. In this brand of OOP, there is usually a special name such as or used to refer to the current object. In OOP, computer programs are designed by making them out of objects that interact with one another. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types. Many of the most widely used programming languages (such as C++, Java, Python, etc.) are multi-paradigm and they support object-oriented programming to a greater or lesser degree, typically in combination with impera ...

Object Model
In computing, object model has two related but distinct meanings: # The properties of objects in general in a specific computer programming language, technology, notation or methodology that uses them. Examples are the object models of ''Java'', the '' Component Object Model (COM)'', or ''Object-Modeling Technique (OMT)''. Such object models are usually defined using concepts such as class, generic function, message, inheritance, polymorphism, and encapsulation. There is an extensive literature on formalized object models as a subset of the formal semantics of programming languages. # A collection of objects or classes through which a program can examine and manipulate some specific parts of its world. In other words, the object-oriented interface to some service or system. Such an interface is said to be the ''object model of'' the represented service or system. For example, the Document Object Model (DOMis a collection of objects that represent a web page, page in a web br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Management
Network management is the process of administering and managing computer networks. Services provided by this discipline include fault analysis, performance management, provisioning of networks and maintaining quality of service. Network management software is used by network administrators to help perform these functions. Technologies A small number of accessory methods exist to support network and network device management. Network management allows IT professionals to monitor network components within large network area. Access methods include the SNMP, command-line interface (CLI), custom XML, CMIP, Windows Management Instrumentation (WMI), Transaction Language 1 (TL1), CORBA, NETCONF, and the Java Management Extensions (JMX).

Network Management Software
Network management software is software that is used to provision, discover, monitor and maintain computer networks. Purpose With the expansion of the World Wide Web and the Internet, computer networks have become very large and complex, making them impossible to manage manually. In response, a suite of network management software was developed to help reduce the burden of managing the growing complexity of computer networks. Network management software usually collects information about network devices (which are called Nodes) using protocols like SNMP, ICMP, CDP etc. This information is then presented to network administrators in an easy to understand and accessible manner to help them quickly identify and remediate problems. Problems may present itself in the form of network faults, performance bottlenecks, compliance issues etc. Some advanced network management software may rectify network problems automatically. Network management software may also help with tasks involved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Method Invocation
In a distributed computing environment, distributed object communication realizes communication between distributed objects. The main role is to allow objects to access data and invoke methods on remote objects (objects residing in non-local memory space). Invoking a method on a remote object is known as remote method invocation (RMI) or remote invocation, and is the object-oriented programming analog of a remote procedure call (RPC). Class stubs and skeletons The widely used approach on how to implement the communication channel is realized by using stubs and skeletons. They are generated objects whose structure and behavior depends on chosen communication protocol, but in general provide additional functionality that ensures reliable communication over the network. In RMI, a stub (which is the bit on the client) is defined by the programmer as an interface. The rmic (rmi compiler) uses this to create the class stub. The stub performs type checking. The skeleton is defined in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
