instant messaging and real-time network capabilities into applications without having to build a server-side hardware environment. Melting cloud for developers of the different scenarios required to provide a range of products, technology solutions, including: Client IM components, client IM infrastructure, service-side rest API, client real-time network communication Base library. With these solutions, developers can build instant messaging products directly in their applications, and can crea
Current results: Speaker read local data, Mic recorded real-time data, can be 90% to eliminate the echo, Aecdelay also need to tune, NS and VAD are normally available. First ensure the AEC normal, next speaker real-time network data, from double talk there is a long way, refueling.

Server (NPS ). NPS is a component in Longhorn that replaces the IAS (Internet Authentication Service) function in Windows Server 2003. Our Server operating system must use Longhorn to apply to the entire local network. How NAP works As mentioned above, not all computers that want to enter comply with the security policy. If a computer that does not meet the requirements is not forcibly prohibited, we als
confusion of the project development process and the difficulty of the task, resulting in the development cycle becoming longer. This affects the project as a whole, and such things are not allowed to happen. And more importantly, a good team needs a better manager and decision maker. Strict control of the project's growth direction, project development cycle, so that everyone in the team on the right path. The whole idea of the project is decided, so that everyone in the team is unified. Can d

Due to the use of IPv6 technology, the city security system has developed by leaps and bounds. The application of IPv6 technology, the latest application results such as video monitoring, videophone, Route Navigation, location query, and traffic conditions are more powerful. IPv6 is gradually integrated into various application systems in other aspects of urban security, such as hotel security management, community security management, and bank security management.
With the advent of IPv6 techn
