The similarities and differences between RTSP, RTMP, and HTTPCommon:1:RTSP RTMP HTTP is applied at the application layer.2: Theoretically RTSP rtmphttp can do live and on-demand, but generally do live with RTSP RTMP, do on-demand http. Video conferencing when the original SIP protocol, and now basically replaced by the RTMP protocol.Difference:1:http: Hypertext Transfer Protocol (FTP is a file Transfer Protocol).HTTP: (Real Time streaming Protocol), l

::string stream_id, cricket::videorenderer* renderer); BOOL Setvideocapture (const std::string cam_device); }; Specific function descriptions can be seen in the corresponding API description. As Google has said, it has been involved in the development and implementation of the video conferencing and peer communication sections of the HTML 5 standard, although it is not yet a formal standard, but we can see the future use of Web developers

Do you want to save money by dialing long-distance calls over the network? Chip will take Skype as an example, from the hardware and software configuration, commissioning, to introduce you how to make a phone call through the network, with online friends voice chat, hold a multiplayer voice conferencing and related use skills to help you understand, use the internet phone. Currently, Skype is a very popular internet telephony software, unlike previou

Broadband access services to provide users with more than 10M of access to the bandwidth of the Internet speed, users will no longer need to network traffic congestion and look at the network sigh, and users can enjoy a wealth of local bandwidth resources and broadband services.Video conferencing is implemented through MPLS VPN. Netcom's video conferencing service utilizes the communication network, throug

The Softswitch device has become one of the important devices in the networking device. Here we mainly introduce the detailed analysis of key routing technologies of the softswitch device. Based on the DNS system, ENUM mainly draws on the basic idea of DNS. ENUMDNS adopts a tree structure and hierarchical authorization mechanism, which completes the route from E.164 number to URI to IP address step by step, the distribution of E.164 numbers, domain names, and data is effectively realized, and th

sessions on the IP network. The SIP protocol uses HTTP, SMTP, and other protocols to support proxy, redirection, user registration, and other functions, and supports user mobility. Through cooperation with RTP/RTCP, SDP, RTSP, and other protocols and DNS, SIP supports voice, video, Data, E-mail, status, IM, chat, and games. The SIP protocol can be transmitted over TCP or UDP. Because the SIP itself has a handshake mechanism, UDP is preferred. SIGTRAN Protocol SIGTRAN protocol signaling Transfe

, and the communication time will also grow. The average access time is 27 minutes, but the traffic volume is small. All of this will make the network load heavier and heavier, and impede the normal communication of the PSTN. Therefore, with the continuous development of Internet access services, corresponding measures must be taken to solve the conflicts between the two business development and ensure the coordinated development of the two. Currently

1 Introduction Telecom operators around the world are facing tremendous pressure from the constant technological innovation and the constant pursuit of communication methods by users. In particular, the profit of the traditional main business PSTN of fixed network operators is declining year by year. On the one hand, the free services of instant communication, P2P voice and streaming media such as MSN on the Internet have greatly attracted the attenti

SoftX3000 through TMG8010, the Softswitch is used to process V5 signaling and complete V5 user access. TMG8010 supports downstream V5 access. After TMG8010 ends V5 signaling, it is converted to H.248 and reported to the softswitch for processing, access V5 users. For the voice access of traditional xDSL users, the DSLAM device enables comprehensive access to user-side voice and data, implements voice and data separation on the DSLAM device, and implements broadband access through the DSLAM upli

data packets are sent over the Internet to the destination IP Phone gateway. For areas where the Internet does not extend to or where no gateway is yet set up, you can set a route. The nearest gateway transfers the route through the long-distance telephone network to implement communication services. III. Basic Structure of IP Phones The basic structure of the IP Phone is composed of the gateway GW) and the gatekeeper GK. The main functions of the gateway are signaling processing, H.323 protoco

is a good choice. When the network size is large, this will bring about huge maintenance work. 2. Hierarchical networking structure of softswitch Devices　 The lower-level Softswitch is interconnected with the upper-layer Softswitch, and the routing information between the softswitch is static. The SIP/SIP-T or BICC can be used between the softswitch. The characteristics of this networking mode are as follows: the lower-level Softswitch is interconnected with the upper-layer Softswitch, the rout

deploy and reliable for communication. It provides a wide range of bandwidth and low transmission latency. However, its resource utilization is low, expensive, and the point-to-point structure is not flexible enough. Circuit Switching connection model the user router connects to CSU/DSU through the serial port cable, and CSU/DSU connects to the carrier's Wan switch through the access line to access the circuit switching network. The most typical circuit switching networks are Public Switched Te
