(ar) Transition bezeichnet ein informatisches Paradigma im Rahmen von Kommunikationssystemen das den Übergang zwischen Mechanismen, d. h. Funktionen eines Kommunikationssystems, insbesondere Dienst- und Protokollbestandteile, beschreibt. Bei einer Transition werden kontextabhängig funktional vergleichbare Mechanismen innerhalb eines Kommunikationssystems ineinander überführt. Das Ziel ist es, eine möglichst gleichbleibende und hohe Qualität bzw. Dienstgüte sicherzustellen. (de) Transition refers to a computer science paradigm in the context of communication systems which describes the change of communication mechanisms, i.e., functions of a communication system, in particular, service and protocol components. In a transition, communication mechanisms within a system are replaced by functionally comparable mechanisms with the aim to ensure the highest possible quality, e.g., as captured by the quality of service. Transitions enable communication systems to adapt to changing conditions during runtime. This change in conditions can, for example, be a rapid increase in the load on a certain service that may be caused, e.g., by large gatherings of people with mobile devices. A transition often impacts multiple mechanisms at different communication layers of a layered architecture. Mechanisms are given as conceptual elements of a networked communication system and are linked to specific functional units, for example, as a service or protocol component. In some cases, a mechanism can also comprise an entire protocol. For example on the transmission layer, LTE can be regarded as such a mechanism. Following this definition, there exist numerous communication mechanisms that are partly equivalent in their basic functionality, such as Wi-Fi, Bluetooth and ZigBee for local wireless networks and UMTS and LTE for broadband wireless connections. For example, LTE and Wi-Fi have equivalent basic functionality, but they are technologically significantly different in their design and operation. Mechanisms affected by transitions are often components of a protocol or service. For example, in case of video streaming/transmission, the use of different video data encoding can be carried out depending on the available data transmission rate. These changes are controlled and implemented by transitions; A research example is a context-aware video adaptation service to support mobile video applications. Through analyzing the current processes in a communication system, it is possible to determine which transitions need to be executed at which communication layer in order to meet the quality requirements. In order for communication systems to adapt to the respective framework conditions, architectural approaches of self-organizing, adaptive systems can be used, such as the MAPE cycle (Monitor-Analyze-Plan-Execute). This central concept of Autonomic Computing can be used to determine the state of the communication system, to analyze the monitoring data and to plan and execute the necessary transition(s). A central goal is that users do not consciously perceive a transition while running applications and that the functionality of the used services is perceived as smooth and fluid. (en) |
