developer. When you start to learn hardware, others may not agree. A friend of ZTE also told me that a person cannot finish everything. I also understand this, but I hope I can do better. However, when you are familiar with hardware, you may feel that you are familiar with software and hardware, and your colleagues are also familiar with it. At this time, I can take the hardware materials to the company, and no one will be surprised. I am proud that I have made an IAD (

The Next Generation Network (NGN) is a hot topic in communication industry at present. As for the next generation optical network, taking SoftSwitch technology as the core, using high-capacity High density wavelength division system, large capacity optical switch with automatic configuration function, a new generation of optical routers, all kinds of low-end optical systems suitable for different occasions, (such as MSTP and RPR), All of these intelli

SDH is a very mature and strict transmission network system, it has been the birth of a wide range of application support, has become the world's core network of the main transmission technology. China from 1995 on the main line began to turn to the SDH network, China's SDH transmission network is to support the number of fixed telephone users in China as the world's first network of telephone users, the current operators of the metropolitan area network is mostly using SDH system. But in the d

is the core function entity of POC business implementation. From the point of view of internal implementation technology, POC server has two kinds of implementation, integrated service platform and soft switching mode. In the integrated service platform mode, the POC server is responsible for call control and media processing, and the internal modules are tightly coupled. This approach can be implemented using pure software, or it can be used to process the API development of hardware boards b

throughout the communication industry, and the service quality will be higher and higher, the service types and functions are becoming more and more complete, and the response service price will be lower and lower. 2. VoIP technology development trend (1) From audible to visual development. Videophone is a new weapon to expand the market. (2) From wired to wireless. Mobile VPN is also the future market darling. (3) transition from hardware to software. With the continuous development of technol

At present, China's core switches are developing very rapidly, while also promoting the continuous improvement and Stability of core switches. Below we mainly analyze the evolution of the core switch architecture and the principles of various architectures. Applications are always the driving force behind technological development. In the face of increasingly complex business applications, the technical architecture of network devices has become a key factor in the scope of application of device

The core switch is still quite common. So I studied the Architecture Evolution of the core switch and shared it with you here. I hope it will be useful to you. Applications are always the driving force behind technological development. In the face of increasingly complex business applications, the technical architecture of network devices has become a key factor in the scope of application of devices. Different application environments require different network devices. For example, the applicat

implementation, and other new technologies. To implement network security policies, vswitches and vrouters must be able to identify application streams, which are also called stream classification. Firewall proxy is a software that supports status classification by line rate and provides a comprehensive dynamic status manager for a specific application or an application interface that provides this capability. As the firewall switching proxy performs fire detection at a wire speed, network desi

protocol to a larger network. In this system structure, the control module no longer processes path control. The distributed routing architecture can provide 1000 calls per second, making it an ideal choice for core or ATM switches in the WAN. In order to implement the distributed routing and call architecture, researchers at the Bell laboratory used the ATLANTA chip of Lucent Technology to form an exchange hardware. In addition, they also used ERM devices that support API business control, the

may be necessary to wait. After all, ICE is not a standard for google... I will wait for google to upgrade... Http://www.helome.com The video and audio parts are based on WebRTC. Some progress has been made on compatibility issues, but in general it is a tough nut to crack. I have already implemented the video demo of chrome 2 android, and I am currently working on a platform similar to opentok. You can learn at present, but it is not a good time for production. The whole community, such as sup

defined as b2bua models. The reason for this is that value-added services are often called in a stateful manner, this requirement is far beyond the scope of basic call proxy. Applications on the b2bua application server can fully complete the roles of sip ua, SIP registration server, and SIP proxy server. Here are some b2bua application examples: Online billing and prepayment Servers that support resource priority and QoS Multi-Point Conference Server IVR Server PBX applications and

The bearer part is mainly responsible for speech processing, including speech codec, encryption and decryption, and forwarding of recordings. The advantage is: 1) reduce the overall complexity of the system. 2) Improve system scalability. Especially if the number of users goes up, this structure is better extended. This is a typical

On the other hand, I have the honor to stand on the shoulders of giants and think about it. Foreign countries have made great achievements in the software field, especially the Open Source Field. Our company is a little timid in introducing

The next generation network telephone exchange system is based on the latest VoIP group voice protocol and the world's leading Softswitch technology, A high-quality digital broadband communication platform that integrates the user's Lan, broadband access network, Internet and traditional PSTN Telephone networks. It represents the future development trend of telecom networks and services, and supports and promotes the smooth evolution of the Next Gener

through a telephone switch. A call is made through an IP network using a telephone number. The sender gateway identifies the caller and translates the phone number/gateway IP address, initiate an IP phone call, connect to the gateway closest to the called call, and complete the voice encoding and packaging. The Receiving Terminal gateway can unpack, decode, and connect to the called call. The gateway is used to correspond to and translate IP addresses and phone numbers, as well as voice coding/

Many meetings are not limited to end-to-end calls between two points. 10) Many vendors say they have high-definition conferencing systems. What should I do? When selecting a high-definition conferencing system, consider the following factors: Fully demonstrate system functions; Cost effectiveness; Real HD quality vsFCIF, 2CIF, 4CIF; Market development and product development direction; The product adopts

I. SIP Concept Session Initiation Protocol (SIP) is an application-layer control Protocol used to establish, modify, and terminate multimedia sessions. sessions can be IP phones, multimedia distribution, and multimedia meetings. It is the core protocol of the IETF multimedia data and control architecture (RFC3261 is the latest RFC document ). The main purpose is to solve the signaling control in the IP network and communicate with the softswitch platf
