| dc.description.abstract | Enterprise IT organizations started to face issues related to managing applications over the slow speed Wide Area Network (WAN) circuits a few years ago with the appearance and use of file-sharing applications over their WANs and/or Internet between headquarters and branch offices. The pain has continued to grow with introduction of mission critical transactional type data along with voice and video traffic over these networks.
For this very reason several techniques were developed and implemented over the years by the vendors and service providers to help the Enterprise organization cope with these problems.
This field project report provides an overview of Quality of Service (QoS) and its implementation in Enterprise Networks for Engineering Managers. The author will discuss the best practices around developing designs for architectures already in place, as well as the business and technical challenges that are faced by Engineering Managers in enterprise organizations when deploying QoS. While the project focuses on QoS implementation of WAN, similar concepts can be used for any type of implementation throughout the network.
The author will first address the issue of bandwidth utilization and how its use has increased in recent years, what type of applications are driving it and the issues enterprise organizations are having in managing it. Next, the various industry standard solutions available to tackle this issue and the advantages of deploying them in the network will be discussed. Recommendations on the use of Project Planning guidelines to implement this critical project within the company and strategic steps that can be used to accomplish the goal will follow.
Finally, cost analysis will show that increasing the bandwidth on the WAN can simply add cost to the enterprise organizations in most cases, whereas the proper use of QoS can help the organization reduce cost while utilizing the existing circuits while delivering the same level of service.
The author recommends the use of QoS in networks to manage traffic but does not rule out the possibility of increasing bandwidth in the enterprise network or the combination of both. | |
