Abstract

In terms of provisioning of guaranteed QoS to the end-user, the performance of remote servers is a critical issue for internet service providers to remain competitive in the market. The end-user would like to have a quick and instant response from the webmail server to enjoy the service. Load and congestion are the greatest hurdles in web based linkage and conversation. The efficiency of web page retrieval is degraded due to the peak use of internet and also because of its highly complex architecture. This paper provides an experimental effort to analyze the effect of load and congestion on web services and measures the performance characteristics like Response time, Latency, jitter, Round Trip Time, hits lost ratio, Page error rates, sending and receiving speed, availability and reliability for accessing different popular and vastly used remote servers (Yahoo Server, Gmail Server, Hotmail Server) to conclude, how load and congestion cause the increment in latency of services? Is there any significant relationship between congestion and hop counts? We contributed new and novel results for further discussions.

Key words: QoS, congestion avoidance, load, latency, response time, congestion, hop count’s relationship.
