Recently, nodejs has been used to implement a resumed upload protocol for Tus, with several intermittent changes in the middle.CodeAddress: https://github.com/maddemon/tus-demoIt's just a demo, so the code is not complete, such as exception capture or something, but I just want to implement the core code. After all, it is not a real project development. Tus Protocol address.This is an HTTP-based resumable

What is HTTP? Simply put, it is a communication specification based on the application layer: both parties need to communicate, and everyone must abide by this specification, which is the HTTP protocol. What can the HTTP protocol do? Most people will first think of: browsing the Web page. Yes, Web browsing is the main application of HTTP, but it does not mean that HTTP can only be used for Web browsin

Socket is used when learning Java, but I still don't understand what is going on. There is no foundation for computer networks. I found some information everywhere. A rough summary of the useful information is provided to facilitate a deeper understanding in the future. For more information, see. I. Differences between the Tup protocol and the UDP protocol TCP-the transmission control

Layer-7 network division In 1978, the International Organization for Standardization (ISO) proposed the "Open System Interconnection Reference Model", the famous OSI/RM model (Open System Interconnection/Reference Model ). It divides the communication protocol of the computer network architecture into seven layers:Layer 7: Application LayerLayer 6: Presentation LayerLayer 5: Session LayerLayer 4: Transport LayerLayer 3: Network LayerLayer 2: Data Lin

ObjectiveWhen the Mqtt protocol was born, it was never considered for transmission over HTTP. This is also normal, network constrained, unstable network is not suitable for HTTP (2g/3g network everyone using WAP is not OK). On the desktop side of the network more abundant, although the pure text contrast binary is not much advantage, subject to historical legacy and usage habits, as well as a large number of traditional infrastructure to facilitate co

"TCP/IP Detailed Volume 1: Protocol" chapter 6th icmp:internet Control Message Protocol---reading notes1. IntroductionICMP is considered to be an integral part of the IP layer, which transmits error messages and other information that needs attention. ICMP packets are typically used by the IP layer or higher-level protocols (TCP or UDP). Some ICMP packets return the error message to the user process.The ICM
