Abstract
As e-commerce services are exponentially growing, businesses need quantitative estimates of client-perceived response times to continuously improve the quality of their services. Current server-side nonintrusive measurement techniques are limited to no secured HTTP traffic. In this paper, we present the design and evaluation a monitor, namely sMonitor, which is able to measure client-perceived response times for both HTTP and HTTPS traffic. At the heart of sMonitor is a novel size-based analysis method that parses live packets to delimit different web pages and to infer their response times. The method is based on the observation that most HTTP(S)-compatible browsers send significantly larger requests for container objects than those for embedded objects. SMonitor is designed to operate accurately in the presence of complicated browser behaviors, such as parallel downloading of multiple web pages and HTTP pipelining, as well as packet losses and delays. It requires only to passively collecting network traffic in and out of the monitored secured services. We conduct comprehensive experiments across a wide range of operating conditions using live secured Internet services, on the Planet Lab, and on controlled networks.
Existing System:
WITH recent technology developments, secured Internet services are the foundation for various e-commerce services, such as online banking, shopping, auctions, and payments. For these e-commerce services, the Internet is a highly competitive environment. Clients have many choices when they are seeking quality services. Whenever an ecommerce service cannot meet their quality requirements, they can turn to elsewhere much more easily than in traditional business environments. This makes it especially critical for e-commerce service providers to offer quantifiable service quality to attract new clients while retaining old ones. Client-perceived response time is a key measure of client-experienced service quality. In deciding whether to continue using one e-commerce service, 46 percent clients want to have quick checkout process and 40 percent want to have fast page view response time.
Proposed System:
In this paper, we present sMonitor for measuring client perceived response times for both secured and unsecured Internet services nonintrusive. At the heart of sMonitor is a novel packet-size-based analysis method that parses live packets to delimit different WebPages retrieved by different clients at the same time and infers their response times. The analysis method is based on the observation that most HTTP(S)-compatible browsers send significantly larger requests for container objects than those for embedded objects. Note that the analysis method is based on protocol features of HTTP and HTTPS. Therefore, although the use of web services evolves very quickly.
