MMS (Microsoft Media Server Protocol) protocol Overview

MMS (Microsoft Media Server Protocol) protocol Overview:
A protocol used to access and stream receive. ASF files on the Windows Media Server. The MMS protocol is used to access unicast content on Windows Media publishing points. MMS is the default method for connecting to the Windows Media Unicast service. If the audience type a URL in Windows Media Player to connect to the content, rather than accessing the content through a hyperlink, they must reference the stream using the MMS protocol.
When you connect to a publishing point using the MMS protocol, use protocol flip to obtain the optimal connection. Protocol flip begins with an attempt to connect to the client through mmsu. Mmst is a combination of MMS protocol and UDP data transmission. If the mmsu connection fails, the server tries to use mmst. Mmst is a combination of MMS protocol and TCP data transmission.
If you want to connect to the indexed. ASF file and want to fast forward, backward, pause, start, and stop the stream, you must use MMs. You cannot use the UNC path to fast forward or backward.
If you connect to a publishing point from an independent Windows Media Player, you must specify the URL of the unicast content. If the content is published on demand at the main publishing point, the URL consists of the server name and. ASF file name. For example:
MMS: // windows_media_server/sample. ASF
Here, windows_media_server is the name of the Windows Media Server, and sample. ASF is the file name of the. ASF file you want to convert it into a stream.
If you want to publish real-time content through broadcast unicast, the URL consists of the server name and the alias of the publishing point. For example:
MMS: // windows_media_server/liveevents
Here, windows_media_server is the name of the Windows Media Server, while liveevents is the name of the release.

RTSP

The real-time stream protocol RTSP is jointly proposed by RealNetworks and Netscape, which defines how one-to-multiple applications can effectively transmit multimedia data over an IP network. RTSP is located on RTP and RTCP in the architecture. It uses TCP or RTP for data transmission. Compared with RTSP, HTTP transmits HTML, while RTP transmits multimedia data. HTTP requests are sent by the client and the server responds. When RTSP is used, both the client and server can send requests, that is, RTSP can be bidirectional.
