, which provides reliability, scalability, and open architecture, this Service supports user-oriented commercial services provided by multiple suppliers and multi-protocol networks. The Softswitch technology classifies the core functions of the previous circuit switching and distributes the functions to the backbone network of the packet network in the form of functional software components. This hierarchical distributed architecture is programmable a
The concept of softswitch was born
The concept of softswitch originated first in the United States. At that time, in the enterprise network environment, users used Ethernet-based phones to implement the PBX function through a set of Call Control Software Based on PC servers ). For such a set of equipment, the system does not need to separately lay the network, but can achieve unified management and maintena
design a unified network management platform that includes business implementation.As the core device of NGN, softswitch manages a variety of data products, such as signaling gateways, access gateways, relay gateways, Smart terminal devices, and AAA servers. Therefore, it is imperative to build a powerful, comprehensive, and robust and scalable unified management platform for Softswitch networks.2J2EE Arch
With the rapid development of computer and network technology, call centers are being used by more and more enterprises and organizations to carry out customer service, marketing, technical support and other specific business activities. The stability and security of a call center system of an enterprise and an organization are the image of an enterprise and an organization, which has become the important choice for the call center to ensure the safe operation of the system, prevent the accident
service function in the soft switch.2. Softswitch TechnologyThe concept of softswitch Soft switch was proposed by the Bell lab of Lucent in 1997. The original intention was to integrate the existing traditional PSTN circuit switching network with the IP/ATM data network.As the control entity of the Next Generation Network, Softswitch provides Call Control and Co
As the core technology of the Next Generation Network, the development of Softswitch technology has been very mature so far. When data services gradually replace voice services as the main source of revenue, the evolution to a data-based group network is inevitable. As voice is still an important service, the next generation network must provide QoS Assurance according to different service requirements. Therefore, the main driving force behind the evo
I believe many people think that the Softswitch technology will be the core of the future of NGN. Here we will mainly introduce how to use the Softswitch technology to improve the overall performance of our network, the communication network has changed from a technology-driven model to a market-and business-driven model. The customer-centric and market-oriented model has become an inevitable trend for the

Softswitch TechnologyThe concept of Soft switch was proposed by Bell Laboratory of longxun in 1997 to integrate the existing traditional PSTN Circuit Switching Network with IP/ATM data network. As the control entity of the Next Generation Network, Softswitch provides Call Control and Connection Control functions for businesses with real-time requirements for the Next Gen
NextGenerationNetwork (NGN) is a new concept used by the network to describe future telecommunication networks. It is like a big umbrella, covers the fixed network, Internet, mobile network, core network, man, access network, user resident network and many other fields. The evolution of technology has brought about the rapid development of network convergence, telecom business integration, and personalized communication services. As a core technology of NGN,
Broadband ip man-based wireless and IP multi-service access applications The voice service is still the main growth point of profit of domestic operators. While building a broadband MAN to implement data services, it also carries voice services on the established data network to avoid re-laying the cables, so as to achieve the convergence of two network data and voice at a low cost, moving towards triple play will be an inevitable choice for emerging operators.UTSTARCOM's mSwitch
, but the traditional telecom market was not greatly affected. It seems that their business is not in conflict. Until the emergence of VoIP.
In fact, the VoIP technology began to appear in 1990s. However, due to bandwidth restrictions and immature technology, the quality of calls cannot be guaranteed, therefore, it is not favored by consumers like Im. However, bandwidth is no longer a problem today. The technology of VoIP is constantly growing and gradually maturing. Both signaling connection
As businesses painfully realize that any set-up and operation of cloud computing is easy to implement, the adoption of an internal cloud is still much slower than the public cloud. Business risk aversion and complexity pose a lot of risks, and for most companies it is very expensive to hire people with expertise to build and manage the internal cloud. As a result, a self-managed cloud or cloud-hosted data center is becoming a new solution for the ente
NGN features a complex converged network based on multiple IP technology vendors, multiple technologies, and different architectures. Softswitch plays an extremely important role in controlling such a heterogeneous network.
Control is implemented through protocols. The main Protocols involved in implementing Softswitch include H.323, H.248/MEGACO, SIP, SIGTRAN, and BICC.
Check five major protocols
H.323 Pro
The Softswitch technology is worth learning a lot. Here we mainly introduce the media logical channels in the Softswitch technology. This channel carries H.245 information, which is used for media control with capability exchange support. After the caller completes the capability exchange, he/she creates a media logical channel through this channel.

This channel carries voice, video, a

The concept of hosting and non-hosting is constantly coming into the eyes of programmers. We can say that. net is gradually becoming one of the mainstream programming languages and platforms.
When someone asked me what is Softswitch, I directly replied: the network architecture with media gateway is SoftSwitch.
Now we can see that a general computer is used as a telephone switch, so it is a soft switch ).
It is the same because the control logic is separated from the speech exchange hardware by media gateway, so the control logic (Application Layer) can naturally be implemented by software run
