The UDP protocol is also an unreliable transport protocol compared to TCP. So what is the occasion to use the UDP protocol:1. Efficient and reliable environment2. Because the UDP overhead is small (1) does not need three handshake 2) the transmission process does not need to confirm 3), it is appropriate to communicate in a light-weight environment, such as TFTP,
1. IntroductionIP is the most central protocol in the family of TCP/IP protocols. All TCP, UDP, ICMP, and IGMP data are transmitted in an IP datagram format. IP provides unreliable, non-connected datagram delivery services.(1) unreliableIt does not guarantee that IP datagrams will successfully reach their destination. IP only provides the best transport service. In the event of an error, such as a router temporarily running out of buffers, IP has a si
ObjectiveThe MQTT protocol focuses on network and resource-constrained environments, and it is normal to not consider the Web environment at the beginning of the establishment. Nevertheless, it does not mean that it is not suitable for the HTML5 environment.HTML5 WebSocket is a two-channel communication based on TCP, similar to TCP communication, and is suitable for web browser environments. Although the MQTT gene plane chooses TCP as the communicatio
First, prefaceWith the broadcast technology hot, all the Live app, the early live app's various request protocol parameter information did not do any encryption measures, but slowly someone began to use the back door began to brush powder attention tool, you can make a new small Hua Dan minute into the net red.

. HTTP Live Streaming HTTP Live streaming is an HTTP-based streaming media transport protocol proposed by Apple. It cuts an entire audio and video stream into a small audio and video stream that can be downloaded by HTTP and generates a playlist (m3u8), where the client only needs to get a m3u8 playlist of resources to play the audio and video. Can realize live broadcast and on-demand. HLS is the technology to achieve live broadcast on demand, its de
