Smart switches are quite common. So I studied the functions and applications of smart switches and shared them here, hoping to be useful to everyone. When smart switches gradually move towards the edge of the network, they are always faced with various questions from users: whether smart switches are used to make minor use of the edge, whether they can completely solve network congestion problems, and whether they support VoIP, can it replace the fire

Vswitches play an obvious role in networking. As the exchange industry continues to develop, many new types of switches have emerged. Smart switches are one of them, when smart switches gradually move towards the edge of the network, they are always faced with various questions from users: whether smart switches are used to make minor use of the edge, whether they can completely solve network congestion problems, and whether they support VoIP, can it

better the development of small and medium-sized business services, services must be able to provide multi-line voice and data. To this end, service providers can now provide voice and data transmission services with a copper axis as a physical connection. First, broadband DSL In transport, many technologies support voice and data transfer. When data transmission is optimized, synchronous transmission requires a given address to ensure the quality of long-distance calls. The increasingly soph

When it comes to audio applications, the first thing to think about is the music player. Some players can play streaming media, and some can play local music files. With the evolution of the Android platform, more advanced audio APIs are needed. Fortunately, Google has added this API to support low-latency audio streaming and recording.The Android Audio API offers some advanced features that developers can integrate into their own applications. With these APIs, it is now easier to implement

I have summarized the commonly used ITU speech codec for your reference: 1. g.711: pulse code modulation (PCM) of voice Frequencies Encoding type: Expanded PCMEncoding rate: 64 Kbps Theoretical latency: the time for processing a sample (1/8000 seconds = 0.125 milliseconds ); Sound Quality: Long Distance quality;Advantages: Low algorithm complexity, low compression ratio (CD sound quality> 400 Kbps), minimum codec latency (relative to other technologies)Disadvantage: the occupied bandwidth is hi

two applications of KVDB, the following describes the use of KVDB access files, speaking of files, will certainly think of binary, kvdb value of the maximum length: 4M (by default, compression is enabled), that is, we have to access the file size can not exceed 4M, Is it possible that more than 4M of files will not be accessible? The answer is no, one of my colleague Pagnee wrote an example shows that KVDB can be scattered when accessing the file and then the output when the file splicing outpu
