Reprint: http://easydarwin.org/article/Streaming/141.htmlThe 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

description of the PASV passive mode and port active mode for ftp:The FTP protocol uses two TCP connections, one is a command link to pass commands between the FTP client and the server, and the other is a data link to upload or download data.The FTP protocol works in two ways: Port mode (active) and PASV mode (passiv

Port Concept In network technology, Ex *] Network g.] # Yu K # The LN Port has two meanings: one is the physical Port, for example, ADSL Modem, Hub, switch, router is used to connect other network equipment interface, such as RJ-45 port, SC port and so on. The second is the

description (presentation Description), which refers to a collection of one or more media streams that the streaming media server provides to the client, and the description contains information about each media stream in the such as data encoding/decoding algorithm, network address, the content of the media stream.Although the RTSP server also uses identifiers to differentiate each class of connection sessions (session), the RTSP connection is not bound to a transport layer connection (such as

following format:http://host[":" Port][abs_path]HTTP means to locate network resources through the HTTP protocol, the host represents a legitimate Internet host domain name or IP address; port specifies a port number, or null specifies the URI of the requested resource using the default

In running-cmd-netstat-an, The opened port is displayed !! Recently, the virus has been a big headache, but it has also gained a lot. I have learned a little bit about it and I would like to share it with you. Currently, the most common Trojan Horse is based on the TCP/UDP protocol for communication between the client and the server. Since the two protocols are used, it is inevitable to open the listening

Today I'll focus on my view on the SLIP Protocol and PPP protocol on the link layer. Today should be written on the third day, for their own insistence point a praise.Slip agreement In fact not much, it is called Serial Line Imternet protocol, translated into Chinese is a serial Internet protocol.

the same device can reach a higher theoretical transmission level. Serial InterfaceThe serial port, or COM interface, is an extended interface using the serial communication protocol. The serial port appeared around 1980, and the data transmission rate was 115kbps ~ 230 kbps. The serial port is generally used to conn

Introduction to HTTP protocolHTTP is an object-oriented protocol belonging to the application layer, which is suitable for distributed hypermedia information Syst

responsible for data transfer from PPG (Gateway) to mobile device. Push OTA uses two WSP layer services for connection-oriented sessions (confirmed push) and connectionless session (connectionless push), which requires a pre-existing active session between PPG and the client for push using a connection session. That is, a push that requires the caller to receive acknowledgment information, and for connectionless push, the communication is completed through the reserved

Network transmission protocol and http protocol, transmission http protocolOverview: it refers to the constraints and specifications for communication between the server and the client. The data interaction between the client and the server is not disorganized and must follow (based on) certain specifications. Common protocols: A) HTTP and HTTPS Hypertext Transfer Proto
