Abstract
Network administrators are always worried that may not being informed about a failure taken place in
the network, or are informed lately. They are also worried that even if they are informed very soon, they
couldn’t get to the related location to solve the problem. This anxiety is mainly because normally network managers need to go to the network location or at least have access to the internet to be able to do something for fixing the occurred failure. This paper suggests a novel method for remote administration of computer and telecommunication networks. In this approach, (SMS) short massage service is used to inform administrators about a failure, as well as let them send commands for fixing the occurred failure. We set up an application program on one of the manageable network systems or on a system which has access to the internet, then using SNMP protocol; we gather the needed information for the network administrator. Also network managers can send commands to the application software by Short Message Service to let it issue commands for fixing the failure. By taking advantage of this approach, network managers can control and manage their network when they are far from the network location.
INTRODUCTION
Data communication and computer networking facilities are expanding rapidly. Proportional to this expansion, problems relating to network control and administration has also be increased. Physical presence of network administrator or remote access via Internet are identified as common solution to this problem. In these approaches the network administrator will investigate all aspects of network operation and under his access privilege intervene and apply necessary commands. SNMP [1, 2 and 3] and CMIP [4] are two popular network management protocols, however SNMP is a simpler and more favorite than the CMIP SNMP is used to acquire information on network operation status, generation of reports and applying corrective commands to the network devices under administration. In this paper a new approach to network administrator has been adopted which uses the SNMP protocol, based on short message services (SMS). An application is installed on a system which has access to the network under administration. Upon the administrator request, all necessary information will be gathered by this application, using SNMP protocol and then is sent to the administrator via short message service, SMS. In turn the administrator is able to issue commands with certain format applicable to the SMS, to the same application. At this stage the application with the collaboration of SNMP, the issued command will be applied to the target device. The proposed system has been implemented and evaluated in both experimental and real network at Yazd University. Under both circumstances the results show that there would be a drastic reduction of network downtime as well as capability to produce varieties of reports from the network which is being administered. This paper deals with the details of the proposed system in several sections. Section two introduces the SNMP protocol and section three will explain the way short messages are sent and received. Section four is allocated to describe the overall structure of proposed system and in section five the security aspect of this system has been explored. In section six our system is evaluated and following section will discuss some of the related research work. The final section will deal with the outcome of this research work and the conclusion.
