Inter-process communication involves a lot of content, such as for the implementation of inter-process communication needs to use many protocols provided by the API, in the process of remote method calls on the need for a certain data format, which is derived from the data set a way of grouping. There are also multicast network technologies and virtual networking technologies for specific app

The combination of Ethernet and laser wireless communication can give full play to the advantages of the two systems and improve the application range and reliability of the
Linux system programming-inter-process communication: Named Pipe (FIFO), linuxfifoOverview of named MPs queue
Unknown pipeline, because there is no name, can only be used for inter-process communication of kinship (for more details, see "unknown Pipeline"). To overcome this shortcoming, a named pipe (FIFO) is proposed, which is also called famous pipe and FIFO fi

Summary
Optical switch is an important optical passive device, which can break and switch the light signal in optical network system. Optical switches are widely used in optical division/interpolation Multiplexing (OADM), Time Division Multiplexing (TDM), Wavelength Division multiplexing (WDM). Optical switch has become the focus of major communication companies and research units for its high speed, high
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
Since the launch of the SanNiuSignal.DLL, the user is still full of good feedback, in order to better serve the people, I have fixed a lot of bugs, while the DLL open source, the following first introducedA simple communication system developed using this DLL:Which module you want to use to start which module, you can form communication with the customer; specifi

In essence, mmap synchronizes the memory with files on the hard disk. The content in a memory is synchronized to the hard disk file, that is, the file is mapped to the memory. Therefore, communication be
Overview of PipelinesPipelines, also known as nameless pipes, are the oldest form of IPC (interprocess communication) of UNIX systems, and all UNIX systems support this communication mechanism.Nameless pipes have the following features:
1, half duplex, data can only flow in one direction at a time.
2, data can only be written from one end of the pipe and read from the other end.

the preface has recently had an HTTPS-related problem that needs to be addressed, so take the time to learn about the use of HTTPS on the Android platform, while also looking at some of the principles of HTTPS, and share some of the learning experience here.
HTTPS principleHTTPS (Hyper Text Transfer Protocol Secure) is a SSL/TLS based HTTP that all HTTP data is transmitted on top of the SSL/TLS protocol package. The HTTPS protocol, which is based on the HTTP protocol, adds SSL/TLS handshake

This is the fastest form of the IPC mechanism because it does not require intermediate links, but instead maps the information directly from a memory segment to the address space of the calling process. A segment can be created directly by a process, which can then be read and written by as many pr
