Scalability of closed-loop video delivery service
نویسندگان
چکیده
Scalability is a key issue of on-line video service. Different methods have been proposed for the closed-loop video service, such as batching and patching. However, scalability itself has not been formally defined and the condition for a scalable system is not well studied yet. This paper studies scalability and the condition for scalable systems. It is found that when the arrival rate is across the threshold Θ the system becomes scalable. This threshold value depends only on the number of videos, video length, and request distribution. We present an analysis for batching and patching. Comparison of batching, patching, and a new method, scheduled video delivery (SVD), is presented in this paper.

A New Approach in Preliminary Design of Closed Loop Solar Thermal Systems (RESEARCH NOTE)
In this paper, a model for closed loop solar system is presented and an attempt is made to generalize the model to be utilized for primary design of any solar active thermal system. This model may be used for systems in which gas or a liquid are fluids that flow. Two new parameters, namely, the system heat delivery factor and the system heat absorption factor are introduced in the model. These ...

In this research, we address the application of uncertaintyprogramming to design a multi-site, multi-product, multi-period,closed-loop supply chain (CLSC) network. In order to make theresults of this article more realistic, a CLSC for a case study inthe iron and steel industry has been explored. The presentedsupply chain covers three objective functions: maximization ofprofit, minimization of n...

Video conferences are considered as an attractive application in high–performance networks. Nevertheless video conference services are not as broadly used as services like e-mail or the WWW. Most existing video conference systems support open group conferences for transmitting public events, like lectures, TV programs, music concerts, talks, and conferences. Most everyday meetings and consultat...
