Measurement and criteria for Selecting a CDN The original purpose of measurement in CDN network is to judge whether the CDN network has the ability to provide customers with desired content and service. performance implications of data center consolidation by the same CDN is important because it eliminates a possibility that unrelated issues in different CDNs could affect the results[11]. .The measurement is achieved with a combination of hardware and software-based probes distributed around the CDN, as well as using the logs from various servers within the CDN [13]. There are five critical quality metrics. Cache hit ration means the ratio of the amount of cache document divide The total documents. If a CDN network exploits an efficient …show more content…
External measurement using a third party to informs customer of content that the performance verified. There distributed many computers which are used for measurement connected through main internet backbones in several different cities. These computers measure if the specific Web site perform well from the end user’s viewpoints. Information Group is often involved in the external measurement. It is often act as evaluator by analyzing several parameters in a CDN network, the parameters include scalability, manageability, area of coverage, the degree how easy it can be used, budget. For both the internal and external measurement, depend on the types of parameters, different networks statistic acquisition are exploited. For instance, t Traffic monitoring is a measurement technique where the traffic between the client and the surrogate is monitored to know the actual performance metrics[13]. Network probing is a measurement technique where the possible requesting entities are probed in order to determine one or more metrics from each surrogate or a set of surrogates[13]. Surrogate servers can also send feedback to help acquire the data for CDN. In order to obtain the CDN status information, networks statistic acquisition are employed rely on a number of metrics. Stimulation measurement Stimulation tools are always used to measure performance of CDN. In stimulation measure, no actual hardware are involved in this

I am glad to present our report on “Analysis of Centennial College’s Online Portal”. I would like to thank you for being available to help at all times. I would also like to thank Taranjeet Kaur for her collaborative work on this report.
In this paper, we present the first data collection and profiling process result in our research framework. At this time, the second and the third data collection process are still on going. If it is completed, we will conduct the second part of our proposed experiment. The challenges is, we have to obtain an appropriate and enough RAW data that need more prolonged time for trial and error. We have to design scalable devices and computation architecture, since the system proposed will handle high volume of traffic at national level network. A comment and suggestion are welcome.
We need to have a secure services and network and also it must be available sometime up to 24/7/365. To make sure that we are close to our Service level agreement (SLA) with our clients, we must check our performance to find the bottleneck. After identifying our bottlenecks we can plan and see what changes can improve our performance.
When people teach about the “Discovery of America”, most of the time it is a general view of what happened that day. However, recordings of diaries that give humanity a further understanding on the matter still exist and can be analyzed. These recordings are personal experiences from explorers of the New World. John Smith and William Bradford were explorers of America that recorded their trip to the new continent and their encounter with the Indians. The General History and Plymouth Plantation are based on real experiences that have their similarities and differences on what happened during the discovery of America.
In 2008, when the financial crisis occurred, millions of Americans were left without jobs and trillions of dollars of wealth was lost wealth. To make sure the Great Recession would not happen again, President Barrack Obama put into effect the Dodd- Frank Act. With the help of this law, banks will not be able to take irresponsible risks that had negative effects on the American people. Furthermore, with the Volcker Rule embedded into the act, it will ensure that banks are no longer allowed to own, invest, or sponsor hedge funds, private equity funds, or proprietary trading operations for their own profit, unrelated to serving their
4.1.4 What types of metrics would you want to track on your E-Business Web site?
For our purpose we will focus on ECHELON was collects and analyzes signals of various networks. ECHELON was created to monitor
Virtue theory is how a person makes decision right and wrong. What kind of person does one wants to be? Also, it deals with a person characteristic difference between good habits and bad habits and the commitments to their relationship, job, and community. Virtue theory is especially important in medical field. Working in medical field it does not matter if a person is doctor, nurse, or therapist. This type of occupations it is extremely important to keep patients information confidential. Also, working medical workers needs to be good to their patients. Medical Beneficence is to be good the patient. Medical virtue is higher standard of virtue than any other career because; it is not based on person self-interest
Metrics are used to measure aspects of network and protocol performance. The values for such metrics in various scenarios indicate the level of performance of a
The rule behind cloud CDN administrations is the utilization of server systems. This includes advising nearest servers when substance is asked for by a client. This lessened page stacking time. Another approach to speed the procedure is to store content for future use by the same client. The objective is to get substance to the client rapidly, accelerating the time taken for reaction.
The next step is to Choose Individual DES statistics. For this project, various statistics like Delay, Traffic received, Traffic sent and Collision count are selected.
