Network Bandwidth Estimation

Oracle Instantis EnterpriseTrack is a web-based application where users make requests to the server using browsers. The browsers stores the static content in the cache and only dynamic requests are sent to the server. The following table gives an estimate of the client network bandwidth required to run the application.

Bandwidth is calculated on the basis of amount of data transferred over the network (request and received bytes) for a request. An HTTP request may consist of different components and all dynamic components (components not cached by the browser) are taken into consideration. Assuming a page takes 3 seconds to load, the amount of data traveled over the network is calculated and bandwidth for that request is calculated in Mbps (Mega bits per second).

Caching of static application components helps reduce bandwidth used by Oracle Instantis EnterpriseTrack. Caching reduces network roundtrips, which boosts the performance of the application. The proposed bandwidth estimates take caching into consideration. First page hits to the server are not taken into consideration for bandwidth estimation. The first hit to the server is costly as all static web components are fetched from the server. Subsequent requests contact server only for dynamic content.
