[Core Tip] It's still a headache for developers to implement cross-application communication on IOS. How is this problem handled for IOS rivals? This paper discusses the cross-application communication mechanism of the main mobile operating system at present.In the "Silos of application communication--ios" article, we
Simple interprocess communication: Pipelines
Pipelines are the most traditional, simplest, and most efficient interprocess communication method in UNIX. The code for the NetBSD processing pipe is kern/sys_pipe.c, and its read-write function is mounted as a fileops of the file structure and is invoked when read (2), write (2).
Pipe creation
The response function of pipe (2) is real sys_pipe (). It first c
Source: Design of communication protocol in embedded systemThat's wonderful!Companies do projects, embedded systems are large and small, everywhere. Because all are in a system, so all need communication, since the communication is related to the protocol problem.Talking about the agreement, many engineers feel that th
We have introduced the concept and definition of Unified Communication. I believe you have some knowledge about it. Now, let's talk about the knowledge of the Unified Communication System. Of course, the purpose of a system based on this technology is to enable the integration and diversity of our

If your enterprise or customer's business system has not yet reached a high level of complexity, it is not recommended that you immediately use the SOA architecture model for business integration. Because the various implementations of the SOA architecture model now have some complexity.
2-1-2, ESBThe full name of the ESB (Enterprise Service Bus): Business Services Bus is a way of realizing the idea of SOA architecture. Since it is a
I. PreambleIn recent months has been engaged in a distributed asynchronous communication system, today to organize and blog a bit.This is a nationwide communications platform, the performance, massive data, fault tolerance and scalability have very high requirements, so in the system architecture can not be simple to adopt centralized. A simple summary is:1. Data
Wireless synchronous data transmission Communication System Development Kit and application solutions
The wireless synchronous data transmission system of Fuzhou Development Zone huiju Communication Technology Co., Ltd. is equipped with a wireless networking protocol stack to provide powerful self-formed and self-rest
In the previous article, we briefly introduced the IP telephone services of Cisco's Unified Communication System. Here, we want to give you a comprehensive understanding of this system, we will continue to introduce other parts. First, let's review the summary mentioned above.
Cisco Unified Communication
Why is Unified Communication so prevalent? This should start with the Unified Communication System, so let's take a look at the relevant content from the Avaya solution. Later, we will introduce the interoperability and custom functions of Lotus Notes.
The emergence of Avaya Aura's medium-sized enterprise solution makes unified
solved by the outer layer of the Protocol head, and the logic plane problem is solved by each sub-protocol. Haha, I was so witty.However, things are far from over, the client uses the C # language, the server uses the C + + language, the memory layout is not the same, the alignment is not the same, perhaps due to different devices and the size of the end of the problem. In order to solve the problem of realization level, also experienced twists. I don't start talking about the time relationship
(3) Design and implementation of the communication mechanism in the MEF plug-in system, and mef plug-in1. Background
Generally, the C # Event mechanism can be used in WinForm to register and distribute events. However, in the plug-in system, the existing classes cannot be used directly. A plug-in does not contain another plug-in. They are all independently decoup
Ladies and gentlemen, crossing, the last time we were talking about the socket communication address system Call example, let's go on to this example. Gossip Hugh, words return to the positive. Let's talk C chestnuts together!Crossing, the communication address system call we introduced last time effectively solves the
We have made a lot of introductions and explanations on the Unified Communication System, and you must have some knowledge about it. Now, let's give a detailed description of the Terminal Services and system construction of the Unified Communication System. Let's start with
