Architectural Styles, SOLID Principles, and Design Patterns
Architectural Styles
Architectural Styles are reusable design solutions for common problems. They are defined by element types, connectors, topological layout, and semantic constraints. Each style addresses certain quality attributes but has tradeoffs, which are compensated with tactics (e.g., adding resources, intermediaries).
Common Architectural Styles
- Layered: Layers use only downward communication, good for modularity and reuse, but can incur a performance hit. Often associated with the Module
Cisco Router Configuration: Lab Examples
Cisco Router Configuration Examples
This document provides configuration examples for Cisco routers in a lab environment. The configurations cover basic setup, interface configuration, routing protocols, and host definitions.
