socket programming? Generally speaking, many people will say, socket programming is basically listen,accept and send,write, and so on a few basic operations. Yes, as with common file operations, you must know when you write.For the network programming, we also say that TCP/IP, it seems that other network protocols no longer exist. For TCP/IP, we also know that TCP and UDP, the former can guarantee the correct and reliable data, the latter allows data loss. Finally, we also know that you must kn
First, let's first understand what is IPC $
IPC $ (Internet Process Connection) is a resource that shares "named pipes". It is a named pipe open for inter-Process communication. By providing a trusted user name and password, both parties can establish a secure channel and exchange encrypted data through this channel to access remote computers. IPC $ is a new feat
The Tp-link IPC (Network Camera) supports the standard ONVIF protocol, which can be used with the NVR of different vendors that support the ONVIF protocol.
This paper introduces the usage of Tp-link IPC collocation Haikang NVR.

NVR (Network DVR) is the centralized control and management of IPC (Network Camera) of the host device, the camera will monitor the audio and video information uploaded to the NVR, by the NVR for unified storage and forwarding. NVR as a centralized controller, can be monitored, video, playback, camera control and alarm.
This article describes how to configure a Tp-link network camera using Tp-link NVR centralized management.
The Tp-link NVR (network DVR) supports the standard ONVIF protocol, which can be used in conjunction with IPC (network cameras) of different vendors that support the ONVIF protocol.

Connect your IPC, NVR, and client computers to your network. As shown in the following illustration:
The first thing to note is that NULL connections and IPC $ are different concepts. An empty connection is a session established with the server without trust. In other words, it is an anonymous access to the server. IPC $ is a named pipe open for inter-process communication. You can obtain the relevant permissions by verifying the user name and password. Many tools must use

There are certain limitations to using signals and pipelines for process communication. For example, the use of signal transmission of information is limited, although the use of pipelines can transmit a certain amount of information, but can only transfer unformatted byte stream. To address these issues, in the 1970s, the System V version of Unix, released by Att, introduced a new interprocess communication
Since the AllJoyn join session timeout problem has been unresolved, we suspect that alljoyn some internal variables are not cleaned up, so consider putting AllJoyn related functions in a separate process, once the join session timeout, The process is restarted.This is related to the IPC issue.Because we are writing generic modules that need to run on DTV (ARM platform Linux) and Android (NDK), it is important to consider the availability of various

Process is a computer systemThe minimum unit for allocating resources. Each process has a part of its own independent system resources, which are isolated from each other. In order to allow different processes to access resources and coordinate each other, inter-process communi

First, for the IPC, RPC, LPC to make a summary, to provide a context for the later content. I. About the relationship between IPC, RPC, LPC.IPC is a set of methods for the exchange of data among multiple threads in one or more processes. Word, in theory, all cross-threading interactions can be called IPC Communications. IPC
IPC (inter-process communication, cross-process communication) refers to the process of data exchange between two processes, so we first have to understand what a process is and what a thread is.Process: A process is an instance of a running program, which emphasizes the concept of dynamics more than a program, a process is a container for threads, and a process can contain multiple threads but at least one thread. Process is the basic unit of task sc

This article will discuss how to use the inter-process communication mechanism-IPC (inter-process-communication) in the PhP4 environment ). The software environment discussed in this article is Linux + php4.0.4 or later. First, assume that you have installed PhP4 and Unix. To enable PhP4 to use shared memory and semaphores, you must activate the shmop and sysvsem extension modules when compiling the PhP4 program.

The process communication method under Linux is basically inherited from the process communication means on UNIX platform. The two main att that make a significant contribution to the development of UNIX (formerly American Telephone Telegraph abbreviations, Bell Labs and BSD (UC Berkeley's Berkeley Software Release Center), which is also the origin of the American telephone and Telegraph company, have a different focus on interprocess communication.
