Designing the diagrams Entity structure diagram (ESD) The diagram shows how the action entities cooperate with the system. Entity structure diagram (ESD) notations: Entity: An entity is an object that is used on the system and by the system. Action: The actions that are carried out by entities and the actions that affect other entities.
The network planner uses these diagrams to analyze how the network performs in each state, ensuring that the network is optimally designed. Network congestion. Network congestion occurs when a link or node is subjected to a greater data load than it is rated for, resulting in a deterioration of its quality of service.
Example of a JSP diagram. Jackson structured programming ( JSP) is a method for structured programming developed by British software consultant Michael A. Jackson and described in his 1975 book Principles of Program Design. [1] The technique of JSP is to analyze the data structures of the files that a program must read as input and produce as ...
A wireless mesh network ( WMN) is a communications network made up of radio nodes organized in a mesh topology. It can also be a form of wireless ad hoc network. [1] A mesh refers to rich interconnection among devices or nodes. Wireless mesh networks often consist of mesh clients, mesh routers and gateways. Mobility of nodes is less frequent.
Feistel cipher. In cryptography, a Feistel cipher (also known as Luby–Rackoff block cipher) is a symmetric structure used in the construction of block ciphers, named after the German -born physicist and cryptographer Horst Feistel, who did pioneering research while working for IBM; it is also commonly known as a Feistel network.
Network architecture. Network architecture is the design of a computer network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used. In telecommunication, the specification of a network ...
A Nassi–Shneiderman diagram (NSD) in computer programming is a graphical design representation for structured programming. This type of diagram was developed in 1972 by Isaac Nassi and Ben Shneiderman who were both graduate students at Stony Brook University. These diagrams are also called structograms, as they show a program's structures.
