Research proposal submitted to Faculty of Computing & Information Management in partial fulfillment of the requirement for the award of the degree of Master of Science (MSc) in Information System Management of Kenya College of Accountancy (KCA)The fast increasing adoption of information technology and increased digitization has led to generation of large data which needs to be sent across the network. The world is becoming a small globe by the essence of networking and exchange of real information is paramount in many corporate agencies such as banks whose clients access their services throughout the country. Fast and consistent application response across the LAN and WAN help in ensuring uncompromised access to mission critical applications and services and enable high-performance businesses to use their applications to accelerate a competitive advantage. This research covered how LAN and WAN optimization can be achieved through application of various existing technologies which are both on paper and practice. This was significant in establishing trends for emergent technology in this field of information and computer technology. LAN and WAN optimization ensures that the limited available resources are used effectively to ensure effective and efficient performance of the resources which are accessed through the network. Owing to the increased exchange of data, security of the data from access by foreign or unauthorised individuals is fundamental, optimized WAN and LAN is inevitable. This is because, the data on transit passes through different networks, using different protocols, in various format which are vulnerable to security issues. Moreover, data loss as a result of corruption or crashing of existing data bases is one of the challenges facing corporate and thus data back up in a secondary site is important. Real time back up has been achieved as a result of effective WAN network between a primary site and a secondary site. LAN and WAN optimization is therefore and important area of study to establish how security and back up can be enhanced. This further helps in reduction of both capital expenditure as well as the running costs incurred by institutions on network management. The study achieved this through simulation of the various optimization technologies for LAN and WAN and measure the results from various case scenarios.
