Object-Oriented Networks
Object-oriented technology has been in practical use on the public telecommunications network in one form or another for several years. The object orientation permits carriers to easily administer and manage various network elements and gives corporate users the means to easily upgrade, change, and customize telecommunications services without carrier involvement.
Object-oriented technology permits applications to be broken into classes of objects that can be reused and easily modified for use elsewhere. This feature greatly reduces application development time, simplifies maintenance, and increases reliability. With each object being viewed as a separate functional entity, reliability is improved because there are fewer chances that a change will produce new bugs in previously stable sections of code.
The use of objects also improves the productivity of programmers. Each instance of an object draws upon the same piece of error-free code, resulting in less application development time. Over time, this approach also makes it easier to maintain program integrity with changes in personnel.
Objects
In a network-management application, the functions of a switch, multiplexer, bridge or router any device that exists on the network can be described as an object. Each object swaps messages with the network-management system, triggering events such as status and performance reports. Through messaging, the reports can be sent to another object, such as a printer or disk drive.
In the TCP/IP environment, the collection of object definitions that a given management system can work with is called the Management Information Base (MIB). The MIB...
