Queuing theory
The queuing theory focuses on mathematical concepts that analyze the queues or the waiting lines. According to the article, the queue theory is used to predict waiting times, and the queuing lengths. Servers are defined as the computer applications or programs that meet (serve) the commands or requests of other computers (usually referred to as the clients). The clients are connected to the server through the network. The server is expected to meet the commands and requests of many computers. Therefore, the servers need to be designed in a way that will enable them (the servers) to meet the commands and request of the client computers simultaneously.
The queue theory foresees the establishment (the designing) of servers in a way that the servers will be able to meet the commands and requests of the client computers at a time. This in turn avoids “congestion” on the networks (the connection between the servers and the clients).
Control theory
The control theory is a theory that deals with concepts in the mathematical and engineering field. The theory focuses on the features and the behaviors of the dynamical systems. The theory concentrates mostly on the behavior of the dynamical systems. The theory also explains the many ways in which the dynamical systems are altered through feedback. Typically, the control theory focuses on regulating the control system.
The servers (as discussed earlier), are meant to meet the requests and the commands of the client computers. At times, the requests and commands can be too much, in turn causing “traffic”. The control theory ensures that the servers are designed in a manner that they (severs), are able to control the request and the commands that overload the networks. It is through the control theory that servers reject certain requests and commands. The control theory enables the servers to assess the most essential dynamics when the networks are overloaded.
QoS
The Quality of service (QoS) model enables computer networks and serves to offer diverse priorities, to different users and different computer applications. Judging by the application of the Quality of service (QoS) model in the article, it is correct to conclude that the model minimizes the negative effects that come with increase in “traffic congestion” on computer networks.
The Quality of service (QoS) models (as stated earlier), enables computer networks to offer diverse services to diverse users and computer applications. Through the Quality of service (QoS) model, the computer networks and servers are able to offer services (by meeting the requests and commands of the computer applications and users) according to importance.
The model enables the servers to differentiate the important services from the less important services.
Basic features
There are certain features that are considered mandatory for the designing of digital home embedded web servers. These features include the memory module, the internet module, the USB communication module, the infrared communication or the transducer interface module, the power module, among many others.
There are other vital features considered when it comes to the designing of embedded web servers. Among these features is the HTML and XML language (metalanguage basics), the scripting features, the server scripting features (CGI, and Perl), Client scripting features (VBScript, JavaScript DHTML).
Basic principles
There are certain principles that dictate the designing of embedded web servers. These principles range from the data base remote methods, client applications, server script for database, to graphical and interactivity interfaces. Embedded web design is also influenced by the choice of the operating systems. The choice of operating systems could range from Linux, windows, to BSD.
Designing embedded servers
It is a rather sophisticated procedure.The designers must pay close attention of data storing methods, sensors for slow and fast signals, data and code for the systems, internal and external communication buses, microprocessors, operating systems and soon. The embedded systems should strictly incorporate operating systems that coincide with the programming environments of the embedded systems. The embedded systems should also be designed in a manner that regulates energy consumption, and ensures the protection of both input and output features.
Сonclusion
Judging by the discussion, it is evident that the article provides information that could be used in the research. The theories and models enable an individual to comprehend the fundamental features, expectations, and basic rules that apply during the designing of servers.
