When possible, a low-cost service contract should be used to obtain new software features to prolong the service life of the purchased software. If necessary, consider using centralized tools to deliver new software to devices. 7. network security vulnerabilities are blocked-you sho

at the data link layer and the physical layer. A Router service is usually explicitly requested by the end user device. It only processes packets that are requested by other end user devices.2) Another important difference between a router and a bridge is that the router understands the entire network, maintains the topology of the interconnected network, and understands the network status. Therefore, the most effective path can be used to send packets. Gateway: 1. The Gateway (Protocol convert

Now we have SIP (Session Initiation Protocol), which is a pressing problem. SIP was born less than a decade ago in the computer science laboratory. It is the first

Chapter 1 SIPP IntroductionSIPP is a tool software used to test the performance of the SIP protocol. This is a GPL open source software. It contains some basic sipstone user proxy workflows (UAC and UAS) and can be used to create and release multiple calls using invite and B ye. It can also read the XML scenario file, that is, the configuration file that describes any performance tests. It dynamically displays test running statistics (call rate, back-to-back signal latency, and message statistic

In fact, the extension name can contain any letters, numbers, and some punctuation marks. Is the extension name case sensitive? Yes. Sometimes it is case sensitive, sometimes it is not. When users use their VOIP phone to call extension named "office", asterisk does not execute the commands defined in extension named "office. On the other hand, extension nam

The greedy mode matches as many expressions as possible on the premise that the entire expression matches successfully, the non-Greedy pattern matches as little as possible on the premise that the entire expression matches successfully. The non-Greedy mode is only supported by some NFA en
