sip screws

6 side-shaped screw 60 degrees can be a graphic restore (do not know the expression clearly, see the explanation in the discussion))If the space is relatively small, as long as the wrench can be screwed 60 degrees can be installed on the screwThis is the product of a compromise between the twist angle and the side length.ImagineIf it is a square, the side length is long enough, but to twist 90 degrees to restore the graphics, not suitable for small space installationIf it is an octagon or 10-edg

using VC6.0 and is a dialog-based MFC program. The program design adheres to the OOP style. As well as the user interface (Interface) separate from the business logic, the structure is simple and clear, I believe that we are very easy to read code.Since this article introduces a total of four process enumeration methods, we have designed a logical control class inheritance structure such as the following:Figure 5 Demonstrating the program logic control class structureOther than that.

Firewall is a passive network security defense technology, located at the boundary of the network, executing the access control policy between the two networks, preventing the external network from illegally accessing the internal information resources, or preventi

This tool is a real-time analysis of the SIP Communication Protocol, which is the main function of the Communication Engineering of zhongzheng University. In addition, the distributed design can be used to analyze cross-domain sip packets, draw a complete signaling flowchart, and control the web interface... background in view of the fact that there is no free communication protocol analysis software for th

I. Overview Review the video surveillance market, the monitoring platform system used by the signaling control protocol is not unified, resulting in the interconnection of the technical threshold. This is a bit similar to the 80 's China's switch market eight system of the situation. These reasons hinder the network era of large-scale carrier-level video surveillance, remote access, centralized management needs. The industry has explored two ways to solve the problem: From the monitoring industr

Introduction Communication providers and their partners and users are increasingly eager for a new generation of IP-based services. Now we have the SIP Session Initiation Protocol. SIP was born less than a decade ago in the computer science laboratory. It is the first protocol suitable for multi-user sessions in various media content. Now it has become the specification of the Internet Engineering Task Gro

SIP (Session Initiation Protocol) Conversation Initiation Protocol is an application layer control (signaling) protocol for network telephony and conferencing. It is mainly a multimedia communication protocol based on IP network. It can realize the signaling functions are also using RTP as a media transmission protocol. Originally presented by the IETF Mmusic (multiparty multimedia session control) workgroup. SIP
