Core Networking Concepts Every online interaction—fetching a web page or posting a status—can be viewed as input/output. At its heart, network communicasion is simply inter-process communication carried out across machines. The global internet identifies a unique process through the combination of an IP address (which locates the host) and a po ...

Network Protocol Models OSI Reference Model Application Layer: Actual data being transmitted Presentation Layer: Data encryption/decryption Session Layer: Session establishment and connection management Transport Layer: Data transmission methods (datagram, stream) Network Layer: Data routing between networks (IP addressing ...

Netty Overview Netty is an asynchronous event-driven network application framework designed for rapid development of maintainable high-performance protocol servers and clients. Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. Key Character ...

Establishing a signaling layer is the foundational step for peer-to-peer connectivity. This mechanism facilitates the exchange of session control messages, including Session Description Protocol (SDP) offers and answers, along with Interactive Connectivity Establishment (ICE) candidates. While various protocols exist, WebSocket remains a standa ...

Netty is an asynchronous event-driven network application framework that simplifies the development of high-performance protocol servers and clients. This article walks through a minimal but complete client-server communication example built with Netty 4.1, using the Reactor threading model (Main Reactor + Sub Reactors) and line-delimited strin ...

Software Development Architectures Network communication applications generally fall into two primary architectural categories: Client/Server (C/S) and Browser/Server (B/S). The C/S Architecture requires a dedicated client application installed on the user's machine. This architecture typically offers richer user interfaces and higher performan ...

Java IO Streams Overview Various Stream Types Memory Streams ByteArrayInputStream - Memory input stream ByteArrayOutputStream - Memory output stream Important Notes: Memory streams interact between the program and memory, not with files Memory streams are channels from the program to memory and cannot be closed Use Cases: Frequently used data ...

This article demonstrates how to quickly establish server and client functionality using the DSAPI.Network-related HTTP Listener component. The HTTP Listener Server monitors specified computer ports to provide web request parsing services similar to IIS. While commonly used for web pages, this functionality extends to various other applications ...

Introduction to I/O Multiplexing In traditional I/O models, functions like read() and write() handle both the waiting phase and the data transfer phase of I/O operations. Since I/O efficiency is primarily determined by waiting time, a new paradigm emerged: delegate the waiting process to a dedicated mechanism that monitors multiple file descrip ...
