Conway's law. Conway's law describes the link between communication structure of organizations and the systems they design. It is named after the computer programmer Melvin Conway, who introduced the idea in 1967. [ 1] His original wording was: [ 2][ 3] [O]rganizations which design systems (in the broad sense used here) are constrained to ...
The end-to-end principle is a design framework in computer networking. In networks designed according to this principle, guaranteeing certain application-specific features, such as reliability and security, requires that they reside in the communicating end nodes of the network. Intermediary nodes, such as gateways and routers, that exist to ...
Bus (computing) In computer architecture, a bus[ 1] (historically also called data highway[ 2] or databus) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
Messaging pattern. In software architecture, a messaging pattern is an architectural pattern which describes how two different parts of an application, or different systems connect and communicate with each other. There are many aspects to the concept of messaging which can be divided in the following categories: hardware device messaging ...
Service-oriented architecture. In software engineering, service-oriented architecture ( SOA) is an architectural style that focuses on discrete services instead of a monolithic design. [ 1] SOA is a good choice for system integration. [ 2] By consequence, it is also applied in the field of software design where services are provided to the ...
In telecommunications, packet switching is a method of grouping data into short messages in fixed format, i.e. packets, that are transmitted over a digital network. Packets are made of a header and a payload. Data in the header is used by networking hardware to direct the packet to its destination, where the payload is extracted and used by an ...
In software architecture, publish–subscribe is a messaging pattern where publishers categorize messages into classes that are received by subscribers. This is contrasted to the typical messaging pattern model where publishers send messages directly to subscribers. Similarly, subscribers express interest in one or more classes and only receive ...
The system creates a bilateral security architecture in East Asia that is different from the multilateral security architecture in Europe. The US acts as a "hub", and Asian countries like South Korea and Japan are its "spokes". There is a strong connection between the hub and the spoke, but weak or no connections between the spokes themselves. [5]
