Chapter 2 - Basics Client Architecture

Introduction

Well it's the question most asked, How does a MINA based application look like? In this article lets see what's the architecture of MINA based application. Have tried to gather the information from presentations based on MINA.

A Bird's Eye View

Lets take a deeper dive into the details
