The IT managers of all organisations are very much concerned to make proper utilisation of available network bandwidth and to make it sure that sufficient bandwidth is available to every user/application for productive work. With the exponential growth of digitally rich contents and Intranet computing demands for the last few years, the users often perceive that there is insufficient bandwidth available to completely satisfy their needs whereas the problem lies at the end of management who fails to identify certain bandwidth eating unproductive applications. In this paper an attempt is made to analyse and implement a policy framework for optimal utilisation of Intranet bandwidth by considering Organisational Networking System (ONS) of Chanakya Organisation, as a case study. To implement Policy-Based bandwidth management we applied ACLs on: gateway routers; content filters on gateway routers; appropriate network nodes; proxy caches, Apply content filters to restrict prohibited content. To restrict applications and protocols and to priorities traffic, install various bandwidth shaping and priorisitation techniques. Monitor users and, where necessary, prevent their accessing prohibited Content. The findings of the study indicate that there is a need of good netiquette of all stakeholders as per IT policy. The IT policy must be framed and enforced for optimal utilisation of bandwidth in Chanakya Keywords: Bandwidth Management, Organisational Networking System (ONS), Netiquette, Intranet Usage Policy, Traffic Filtering, Mission Critical Application, Network Monitoring. 1. Introduction The organisational networking system is one of the most essential assets for any organisation to support and deliver numerous key services. This is also an integral part of computing environment that supports organisanal business activity and official works [6]. It is not viable for any big organisation to operate if it is not connected to the entire offices spread across the country side. This means, the survival is dependent on good working access of Intranet. Effective Intranet Access requires an information delivery chain consisting of four essential links: (i) content, (ii) connection, (iii) local resources, and (iv) bandwidth management. The content must be in a form accessible by the user. The connectivity is essential to access the content. Furthermore, the resources are required to deliver the content to the end users. These include the local network, computers, necessary tools and skills of network administration team. But bandwidth management is the core issue that attracts attention to provide seamless flow of information. Without proactive management, network capacity fills with viruses and inappropriate traffic, and the connection becomes ineffective [12]. In that case, network management becomes essential. The network management is defined as the control, planning, acquisition, allocation, deployment, coordination and monitoring of the resources of the network [6]. In the current paper, one of the core issues of network management system, i.e. to make available adequate bandwidth is discussed in detail by considering case study of Chanakya Organisation. This organisation has various categories of users with varying network requirements and service utilisation trends. This paper has also tried to identify the major bottleneck applications which generally eat one of the most valuable and limited resources of the organisation‘s network, i.e. bandwidth followed by designing of policy framework by considering both technical and managerial possible solutions. 2. Necessity of Bandwidth Management The bandwidth simply represents the capacity of the communication media to transfer data from source to destination. Wider the route/path for data transmission, more packets of information will be transmitted to the user's Intranet enabled devices. Bandwidth is a gross measurement, taking the total amount of data transferred in a given period of time at a particular rate, without taking into consideration the quality of the signal itself [10]. Furthermore, the bandwidth is responsible for data transfer speed and commonly used in Intranet connections. Bigger the bandwidth quota is, the higher the connection speed and hence quicker it will be to upload and download information. Various Intranet connections are offering different bandwidth standards. For instance, the traditional dial-up Intranet Connection provides a very narrow bandwidth limit of about 56 kbps, while the current broadband connections allow data transfer at much higher speed ranging from 128 kbps to 2 mbps. Bandwidth is both absolutely and relatively much more expensive for any organisation. Many organisations are finding that they still do not have reliable, usable Intranet Access for their offices and staffs despite considerable investment. Improving the Paper ID: SUB155578 1760
