ISP and Internet Service Internship Report

ISP and Internet Service


Internet Service Providers (ISPs) offer access to the Internet and other network resources to their customers. The ISP marketplace is extremely competitive, requiring ISPs to provide their services with limited resources. In this study, I use constrained optimization to reflect the tensions between changing customer demands and infrastructure costs that the ISP faces in its investment decisions. Specifically, I model the traffic routing decisions, the investment in augmenting capacity decisions, and the investment in building network infrastructure decisions made by ISPs.

That is why I choose subject of my report is “ISP and Internet Service”. Working in live servers at Information Service Network Ltd. added huge experiences in upcoming career. Solving real life problems was another key issue. This report takes us through all the details of networking knowledge and experience gathered during this internship period.

In this report I focus primarily on explaining the factors that lead to changes in network performance and extract investment policies for ISPs to maximize the effectiveness of limited resources.

5.1 Discussion and Conclusion

I above has discussed the structure and working method of ISN. where I will discuss about the basic problem of ISN. I have discuss some recommendation or plan for the satisfactory level of services given to the customer. The Basic services have become commodities and customers are looking for new services to add value. Additional offerings such as quality of service, bundled services, banking, e-commerce etc. are also becoming attractive to customers. There is a clear change of strategy both within an ISP and between ISPs.

The purpose of the report was to do an evaluation of the customer satisfaction of Information service  Network and scope for its improvement To survive in the competitive environment ISN should satisfy the customer, otherwise the environment is too competitive to loose the clients. And most of the time clients have a little cost and sometimes no cost to switch to other organization. To satisfy the customer ISN can follow the proposed suggestion and can progress accordingly, which might help ISN to retain the clients and make the clients loyal to the organization. All in all, Internet service provision is an extremely complex and dynamic area and detailed investigation of any part of it is beyond the scope of this report.

I gather a lot of experience and this is a great opportunity for me to complete this internship on “MikroTik Router and Monitoring Software Configuration and Maintenance “Information Service Network (ISN) During this internship, I considered to implement and test the operating system.

Now  I am able to create or maintain different types of routers, which is very helpful for my future. It gives me the chance to meet the real life networking system which is very effective for me in future.
