Smart switches are worth learning a lot. Here we mainly introduce the functions and applications of smart switches. As smart switches are becoming more and more worth learning, here we will mainly introduce the process of moving towards the edge of the network, and we have been faced with various questions from users: whether smart switches are used to make small use of edges, can all network congestion be solved, VoIP is supported, and firewall can b
Whether the smart switch is used for minor edge issues, whether it can completely solve network congestion problems, whether it supports VoIP, and whether it can replace the firewall ......
When the smart switch is gradually moving towards the edge of the network, it is always faced with various questions from users. In fact, smart switches can and cannot.

Many people want to know whether enterprise-level open-source VOIP solutions can be built and whether th
When the intelligent switch gradually to the edge of the network process, has been facing the user's various questions: whether the smart switch for the edge is overqualified, whether it can solve the network congestion problem, whether to support VoIP, can replace the firewall. In fact, the intelligent switch can be, there is no.
The concept of intelligent switch has been given a lot of mythological colors, as if all network problems will be solved.

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
The network is closer to people's lives and work. There are many different problems in the process of getting in touch with the D-link router configuration. How can we solve these problems? The following describes the D-link router. With the rapid popularization of broadband, how to make full use of broadband resources and easily enable multiple users to access the Internet at the same time has become a problem for many families and SOHO users.

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

implement specific functions. For example, 8-bit single-chip microcomputer, 32 ARM, and DSP chip all belong to the category of embedded core chip. The 8-bit MCU market has gradually stabilized, and 32-bit MPU represents the development direction of embedded technology and is accelerating development. In the 32-bit embedded microprocessor market, the ARM Kernel-based microprocessor is in an absolute leading position in the market, so it is particularly important to track the development trend of
Question for Beginners: can PHP programmers implement SOHO programming at home? Are companies willing to hire such programmers? (Most of the communications are conducted online), and SOHO still needs to hire companies ..? A few remote consultants are enough for a month's salary. of course, you must be able to answer questions (like CSDN) from other people and discuss the high score questions for beginners.
