quality of service (QoS)

Today more and more business processes are using different telecommunication and information technologies to facilitate and improve business efficiency. Each business process is organized as a sequence of components which cooperate together in order to achieve common goal. This goal is to provide high quality services for clients. The main component that is used for building such systems is web-service. Web-service is a component that incapsulates a set of functions that can be invoked remotely over the Internet.

Designing the photonic transport networks is the task of great complexity, because of variety traffic queues should be transmitted with different priorities. Task of dynamic supporting the different quality of service (QoS) requirements during transmission over optical channel is even more complex. The most significant aspect for effective transport network designing from economic point of view is the network parameters optimization. In general, the methods and models for quality parameters estimation, developed in teletraffic theory are useful for packet networks as well.
