Skill: Network architecture
The design and implementation of a communication network with respect to its communication disciplines and its interconnection topology. Network architecture deals explicitly with the encoding of information, its transmission,error detection, error correction, and flow control, techniques for addressing subscribers on the network, analysis ofnetwork performance under abnormal or degraded conditions (such as missing communication lines or improperly functioning switching nodes), etc. Examples of generalized network architectures are OSI (open systems interconnection, an architecture propounded by the ISO) and SNA (systems network architecture, proposed and supported by IBM).
