Internet working between OSI and TCP/IP Network Managements with Security Features Requirements

    4 Votes

Powerful and flexible paradigms has been used to integrate OSI network and the TCP/IP internet the application gateway. Drawbacks in micro managements of the gateway causes high commission costs and long delays while responding to critical scenarios. There should be a well defined mechanism to map the access control policy between two domains which are using different security policy. This scenario arise due to the use of different standards across each domain. Aim of this project is to to reduce network management costs and delays by proposing an application gateway that delegates powerful and complex services of the CMIP as well as management functions sent to an agent by a manger. Another objective of this project is to to guarantee the safe communication between two domains by security mechanism converting the security policy in order.

 Answer to the above mentioned problems is by introducing a delegation function. Different functionalities of delegation function is given below

  • Manager had to wait for notifications when a request is made for managed operations
  • It should control management behaviors

Managers should micro manage agents through primitive steps in order to manage the above mentioned non trivial tasks. But this will result in traffic overheads. Delegation function helps to minimize the traffic overhead by delegating

  • Execution of scripts to an agent
  • By allowing managers to write out managed scripts

Script management function can dynamically create the management script based on the needs of a manager. Executions of management script can be delegated to an management system when a manager can't execute specific management functions or when a manger can reduce the burden of the system with excessive management traffics.


Inorder to manage network efficiency among various domains, an integrated management mechanism needs to be introduced. Relations between Managers and Super manager and relation between manager and the agents are specified in super manager which owns them. There are a variety of paradigms which manage the networks without structure modification of the existing network managements in the heterogeneous systems. On of them is application gateway which interconnects the ISO network and TCP/IP internet efficiency and transparently.

Application Gateway Layout

 Application gateway has an end to end role of an agent to a manger and vice versa.  Since protocols used by a manager and agent are different, gateway which serves for the transmitter performs the role of transformation. Application gateway consists of

  • Generic process
  • Processor of management script
  • Name Server
  • Table of management script
  • MIB

Generic Process composed of two phase commit relation between the name server and the processor of management scripts and takes charge of translation of both primary protocol services and management scripts. Whenever delegation function requires, process requests management scripts from the processor. using name server, generic process take the instance address of an actual managed object. Management scripts send out by manager to agent should be understood by him. Management scripts is generated by the processor, searches for script table, and if the script exist, script is transmitted to an agent without the process of the transformation and then waits the response.
