[ back to Tutorials ] [ prev ] [ next ] Reliability Issues in Network Planning Prof. Algirdas Pakstas Date & time: Tuesday, June 14, 2005, 14:00-18:00 ABSTRACT Capacity, Reliability, and Delay are three magic words which are used when concepts of the computer network design are described. While Capacity and Delay are relatively good understood it is not a case for Reliability. Term Reliability is often used interchangeable with Availability and Dependability. Increased Redundancy in the network structure is often considered as important or even the only way to achieve higher levels of Reliability. The goal of the Tutorial is to present a role of Reliability (in a broad sense) in the network design. Factors affecting Performability of the communications Systems are discussed. Reliability in the network design process in a context of systems approach to network design is considered in more detail. Examples of calculations of Reliability figures for different network designs are considered using tool Delite. Reliability support in communications protocols is discussed. Example of simulations and animations of network dynamics is presented using tools ns-2 and nam. INTENDED AUDIENCE: General SPEAKER'S BIOGRAPHY [ back to Tutorials ] [ prev ] [ next ] |
