One setting must contain at least one stream configuration setting.Stream informationThe stream information in the settings includes the bit rate, buffer window, and media attribute settings of the stream. The stream information of video and audio accurately describes the media configurations in the file, including the encoding and decoder used for compressing data (if any )

China's IP routers have developed rapidly and their technology is also very mature. Many people may not understand the connection between IP Routers and SDH devices of the IP transport network, after reading this article, you must have gained a lot. I hope this article will teach you more things. In recent years, the broadband high-speed Internet, with the IP technology as the core and SDH or DWDM as the bearer, has developed rapidly. IP Over SDH is one of the common solutions to achieve IP Broa

PPP (Point-to-Point Protocol) workflow and features PPP (Point-to-Point Protocol) workflow: when a user dials an ISP, the modem of the router confirms the dial and a physical connection occurs. The PC sends a series of LCP groups (encapsulated into multiple PPP frames) to the router ). These groups and their responses select some PPP parameters and work with the network layer. NCP assigns a temporary IP address to the newly accessed PC so that the PC machine becomes a host on the Internet. When

The Network Management proxy and maintenance terminal manages and maintains the ATM switch through this unit, each Service Board collects and reports data through this Unit. In addition, the core part of the ATM switching software-the signaling software includes user-to-network signaling and network-to-network signaling, I .e., UNI/NNI signaling) will run on the hardware of the central con
