![]() Knowing the "car per hour" rate of the road will contribute negligible value in the planning process. Being on time is the reason why car drivers plan a departure time prior to starting any journey that has a finite purpose. Ultimately the success of any network application’s delivery is based on this. Time is the overriding metric that matters to the user experience, nothing else. So how should a road be measured? Cars per hour? Average speed attained? Both? Some other metric? Understanding utilization versus speed will define the experience of any road. I would expect a road architect to be more than just interested in wanting to understand the relationship between utilization of a road and the speed attained on the road. This simple example demonstrates that the number of vehicles on the road is not necessarily a measure of performance, although it could be argued that there are some obvious correlations. I would suggest the answer is obvious, clearly being on time defines a good user experience, being late does not. That the speed of your car is at or close to the speed limit of the road and you'll reach the airport on time. That the road is delivering cars at a rate of 5,000 cars per hour, orĢ. If you are driving to the airport, what is more important to your experience?ġ. How would you react if I replied, "the road to the airport delivers 5,000 cars per hour". If you were to ask me the question, "I have an 11am flight tomorrow. The big disconnect is that bandwidth is not a speed, only a rate. "Time is the overriding metric that matters to the user experience, nothing else." In fact, 1Gbps to the home is now becoming a common reality when, just 5 years ago, 10Mbps was considered fast. Over the years bandwidth offerings have grown from as little as 512Kbps (considered to be the popular definition of a broadband connection) to 10Gbps or higher, especially in the business world. Does more bandwidth really deliver a better user experience? This is a good question, however, a better question would be, "why is a poor user experience still the No.1 service complaint, when the No.1 service solution is to increase the bandwidth"? Not surprising really, it is a bit like buying a new sports car, our first urge is to test the car’s ability to deliver on its published rating of acceleration and top speed. In the USA alone several million so called speed tests are run each and every day. One of the most popular application services on the Internet today is bandwidth measurement. In short, bandwidth is synonymous with speed, and more speed is better for the experience than less speed. This desire is encouraged by the persistent publicity from a myriad of bandwidth providers, that more bandwidth is faster. No matter how much bandwidth is provided our desire always seems to be 'I want more'. Our obsession with bandwidth is essentially driven by our desire for a better Online experience, a poor user experience is frustrating. ![]()
