TCP Server Implementation This example demonstrates a TCP echo server using epoll for efficient I/O multiplexing: #include <sys/epoll.h> #include <netinet/in.h> #include <unistd.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAX_EVENTS 20 #d...
Overview of UDP Communication Modes User Datagram Protocol (UDP) is a connectionless and unreliable protocol. In Qt development, implementing UDP requires understanding three primary transmission modes: Unicast, Broadcast, and Multicast. Effective implementation often depends on how network interfac...
Network programming in Java involves three core components: IP addresses, port numbers, and communication protocols. IP Address An IP address uniquely identifies a device on a network. The loopback address 127.0.0.1 represents the local machine. Port Number Port numbers distinguish between different...
Implementing real-time voice communication in Unity requires capturing audio input, encoding and tranmsitting it over the network, and decoding and playing it on remote clients. This approach avoids reliance on third-party SDKs while maintaining low-latency transmission suitable for local or LAN-bas...
UDP Socket Creation The socket(AF_INET, SOCK_DGRAM, 0) system call creates a UDP socket with the following parameters: AF_INET: Specifies IPv4 address family SOCK_DGRAM: Designates a datagram socket for connectionless UDP communication 0 (or IPPROTO_UDP): Indicates the default UDP protocol sendto()...
Network Communication Overview Network communication requires two essential elements: Addressing: IP address and port number identify communicating endpoints Protocols: Standardized rules governing data exchange (OSI reference model vs TCP/IP model) The TCP/IP model became the de facto standard desp...
Unity3D's default TCP networking can be inefficient for large file transfers due to its reliability mechanisms. UDP offers a faster alternative by sacrificing guaranteed delivery, making it suitable for scenarios where speed is prioritized over perfect reliability. UDP Protocol Fundamentals UDP (Use...
Transport layer protocols facilitate logical communication channels between application processes running on different hosts. While the network layer handles logical communication between hosts, the transport layer extends this capability to specific processes via ports. These protocols operate excl...
Intrdouction to iperf3 iperf3 is version 3.0 of iperf, a network performance testing tool that transmits data streams in one direction over the network. It can adjust transmission rate and data size as needed, and report bandwidth, jitter, and packet loss. Download: https://github.com/esnet/iperf/ i...
Computer networks enable connectivity across diverse hardware and operating systems. To facilitate reliable data exchange, standardized communication rules—known as network protocols—govern transmission formats, rates, and procedures. Key protocols include IP (Internet Protocol) at the network layer...
