Network Programming Instant messaging Program (chat room)------(i) Brief introduction of communication process and communication protocol custom _ programming

Before I begin, I'd like to describe what this so-called communication program is all about. The communication program is similar to a weak version of QQ, login needs to register, after successful login, you can achieve instant communication, group chat, private chat, but also can be transmitted documents. Let's get to the last picture Server side: Client Login:

Communication pre-system-Communication Service design

Let me introduce some of the issues that need attention when designing communication services. 1, the use of short-chain, or long-chain. The advantages of short-chain can be guaranteed to a certain extent the number of concurrent services, each communication is completed, the release of resources, the disadvantage is that each time the need to establish a link, waste of resources,

Process communication mode-thread communication mode

Interprocess: Pipeline, Message queue, signal, shared memory, socketThere are several ways to communicate between processes:(1) Pipes: Pipelines can be used to communicate between affinity processes, allowing one process and another to communicate with a process that has a common ancestor to it.(2) Named pipe (named pipe): The named pipe overcomes the limitation of the pipe without name, so that, in addition to having the functionality that the pipeline has, it allows for inter-process

Serial Can only be transmitted by one person. Sync (Understanding) Establish the direct control of the receiver clock by the sender clock, so that the two sides a

Linux_c Development (5-2) interprocess communication _ Pipeline Communication

Pipeline CommunicationWhat is a pipe? The pipeline is one-way, first-out, and he connects the output of one process with the input of another. One process (write process) writes data at the end of the pipeline, and another process (read process) reads the data from the head of the pipe.Pipeline CreationPipelines include nameless pipes and two of known pipelines, which are used for communication between parent and child processes, which can be used for

Microsoft Next Generation Communication system releases-UC communication

For telecommunications devices such as Cisco, Nortel and Avaya, Tuesday is their bad day. Tomorrow, Bill Gates will announce Microsoft's official foray into the communications equipment industry. The product that Microsoft brings is "unified communication". This is a platform to integrate all communication methods, such as: Voice, video, instant messaging and other information. If the project succeeds, th

The principle of satellite communication

Access (CDMA), that is, different Earth stations occupy the same frequency and the same time, but different random codes are used to distinguish different addresses. It uses the extended spectrum communication technology, has the anti-interference ability, has the good secret communication ability, can flexibly dispatch the channel and so on the advantage. The disadvantage is that the spectrum utilization

Spring consolidated JMS for network communication __spring Consolidated JMS for network communication

what is JMS. The JMS-the Java Message Service-application interface is a Java platform-oriented messaging middleware (MOM) API for sending messages and communicating asynchronously between two applications, or distributed systems. The Java Messaging Service is a platform-independent API, with most MOM providers supporting JMS. the advantages of JMS At present, CORBA, DCOM, RMI and other RPC middleware technologies have been widely used in various fields. But in the face of distributed systems
