This article introduces core networking concepts, explaining what a network is, its classifications, the OSI seven‑layer model and its relation to TCP/IP, common protocols with their port numbers, and the processes of data encapsulation and decapsulation across each layer.
The article compares Google’s A2A coordination protocol with Anthropic’s Model Context Protocol, showing through a financial‑report case study that A2A enables deeper LLM‑driven interactions while MCP provides tool‑wrapper services, evaluates three integration paths, discusses SDK, latency and cost challenges, and predicts A2A could become the dominant orchestration layer for AI agents.
This article explains the differences between Python's typing Protocols and Abstract Base Classes, shows practical code examples, and provides guidelines on when to use each approach to achieve flexible, type‑safe, and maintainable software design.
