Flexible Network Management using Active Network Framework

The growing intelligence of communication equipment and the advances in communication services created a demand for more complex and flexible network management functions. It becomes difficult to handle such a demand by the traditional, simple manager-”management agent” paradigm for network management systems. Mobile agent technology is regarded as one of the promising solutions for handling such demand. We evaluate the efficiency of a mobile agents based network management system, quantitatively as well as qualitatively, by using our prototype SDH (Synchronous Digital Hierarchy) test management functions. The results show effective use of mobile agent technology for network management.

A method to develop common management service in many management application programs based on management service specification using GDMO template

In the OSI (open systems interconnection) management system, many kinds of management application programs are developed in order to manage the communication networks. Therefore, it is necessary to develop applications efficiently. One of methods which develop applications efficiently is that the management system provides common functions to each application as a management service. We propose one method that develops the above management service. We define the management service as a function object. The management system executes the management service based on the management service specifications defined in the GDMO (Guidelines for the Definition of Managed Object) templates.

Verification Of An Optimal Scope-Patterns Decision Method for OSI Management Operation

In this presentation an optimal scope-pattems decision method for efficient OS1 management operation is proposed. The scope-pattems are CMIS operational range-specifications based on the containment relationship between managed objects. The motivation for this study is to improve human interfaces for network management systems by providing a translating function for user-specified operational ranges based on various kinds of relationships into CMIS scope-pattems. The goal of this method is to define optimal scope-patteims for minimizing invoked operations by solving a combinatorial optimization problem. human interface are shown.

Also, the CMIS includes the scope and the filter service parameters for efficient management operation with respect to multiple managed objects. The scope parameter indicates a subtree based on the containment relationship between managed objects, rooted at the base managed object which is to be searched. The search pattems that may be performed are the base object alone, the Nth level subordinates of the base object, the base object and all of its subordinates down to and including the Nth level, and the base object and all of its subordinates. The filter parameter specifies the set of attribute value assertions that define the filter test that is applied to the scoped managed objects. However, network operators are forced to decide the scope parameters by following the above mental information processing, in order to use OS1 management operations efficiently, especially when treating many managed objects. 0 mapping displayed objects to managed objects 0 translating operator-specified operational ranges based on various kinds of relationships (geography, 0 selecting effective scope-pattems for machine processings connection, service, etc.) into CMIS scope-pattems based on the containment relationship Therefore, it is difficult to use present human interfaces with OS1 management operations efficiently. In order to resolve the above issues, a method to achieve user-friendly human interfaces for OS1 management operations is proposed.
