Fact One: File Descriptor Limits Friends who write network server programs in Linux surely know that each TCP connection occupies a file descriptor. Once this file descriptor is exhausted, a new connection attempt will return the error “Socket/File: Can’t open so many files”. At this point, you need to understand the operating system’s limit on … Read more
1. Introduction to TCP/IP The IP protocol is the network layer, the TCP protocol is the transport layer, the HTTP protocol is the application layer, and socket is the code encapsulation and application of the TCP/IP protocol. TCP/IP mainly addresses how data is transmitted over the network, while HTTP mainly deals with how to package … Read more
↓Recommended Follow↓ Network Models: Common models include the OSI network model, TCP/IP network model, and the five-layer protocol network model: The OSI seven-layer network model splits the application layer of the traditional five-layer TCP model into the application layer, presentation layer, and session layer. Application Layer: Responsible for providing a unified interface for applications. Presentation … Read more
