Understanding Open Source protocols: common open source protocols

Open source is already widely used in today's software industry, but does open source mean that users can do whatever they want to do with open source code? The answer is no. Open-source sports also have their own game rules and ethics. Failing to comply with these rules will not only damage the healthy development of the open source movement, but also cause reputational and market losses to violators, and more likely fall into legal disputes and compensation. There are many open-source

Object Code refers to the object code generated after the source code is compiled, similar to the "class library". It provides various interfaces for others to use. According to my understanding, it is something like common DLL, ActiveX, OCX controls. (I don't know if this is correct) The pur

Common understanding of TCP/IP network protocols

The common understanding of TCP/IP network protocols was developed some time ago. network programming was involved and the development process was smooth. However, after the task was completed, I always felt a bit confused. The main reason is that you are not familiar with network protocols and are not clear about some concepts. Later, I spent some time learning

This article compares the transmission performance of five communication protocols, including RMI, Hessian, Burlap, Httpinvoker, and web service, in different data structures and data volumes. RMI is a remote communication protocol provided by the java language. It is stable and efficient and is the basis of EJB. However, it can only be used for communication between JAVA programs. Hessian and Burlap are open source

Common network video camera transmission protocols

connection-oriented network services, designed to provide a reliable end-to-end byte stream on an unreliable interconnected network. The TCP protocol usually requires multiple "handshakes" between the server and the client to establish a connection,Therefore, the overhead of audio and video streams with strong real-time performance in TCP transmission is high.If the network is unstable, audio and video jitter is obvious.. The reliability is often used to transmit Network Camera management comma

Analysis of Common three network protocols

Analysis of the three common network protocols TCP/IP is undoubtedly one of the most important of the three protocols. As the basic protocol of the Internet, it is impossible to access the Internet without it, any Internet-related operations are inseparable from the TCP/IP protocol. However, the TCP/IP protocol is also the most troublesome configuration among the

Knowledge about three common protocols of IP routing: RIP, OSPF, and OSPF

may depend on the number of forwarding times between nodes, the current network running status, data transmission rate, and topology. To find the optimal path, Each router needs to communicate with each other through the routing protocol. The routing protocol is only used to collect data about the current status of the network and find the optimal transmission path. Based on the data, the router can create a route table for future packet forwarding. In addition to the ability to find the optim
