Description
本發明係關於一種多媒體線上廣播系統，尤指一種分散式多媒體線上廣播系統。 The present invention relates to a multimedia online broadcast system, and more particularly to a distributed multimedia online broadcast system.
由於多媒體資訊技術及網路技術之快速發展，使得現今的網際網路可提供的資訊服務越來越多樣化，其中，現有一種多媒體線上廣播系統，主要提供網路使用者透過網際網路線上聽取多媒體廣播。 Due to the rapid development of multimedia information technology and network technology, the information services provided by today's Internet are more and more diverse. Among them, there is a multimedia online broadcasting system, which mainly provides network users to listen through the Internet. Multimedia broadcasting.
目前多媒體線上廣播系統概以二種網路拓撲架構實現之，其中一種採用主從式網路架構；另一種則為點對點(Peer-to-Peer，P2P)網路架構。 At present, the multimedia online broadcasting system is implemented by two network topologies, one of which adopts a master-slave network architecture, and the other is a peer-to-peer (P2P) network architecture.
請參閱圖5所示，該主從式線上廣播系統係包含有；一多媒體廣播伺服器60，係連結至一多媒體供應端50，以獲得多媒體資料；及複數用戶終端機70，係與多媒體廣播伺服器60連結成一主從式網路架構，其中該多媒體廣播伺服器60係為主機，而複數用戶終端機70則為從機。 Referring to FIG. 5, the master-slave online broadcast system includes: a multimedia broadcast server 60 coupled to a multimedia server 50 for obtaining multimedia materials; and a plurality of user terminals 70, and multimedia broadcasts. The server 60 is coupled into a master-slave network architecture, wherein the multimedia broadcast server 60 is a master and the plurality of user terminals 70 are slaves.
再請參閱圖6，點對點式線上廣播系統係包含有：一多媒體廣播伺服器60，係連結至一多媒體供應端50，以獲得多媒體資料；及複數用戶終端機70，係與多媒體廣播伺服器60構成一點對點網路連線架構，其中複數用戶終端機70係透過網路相互連結，並直接或間接連接至該多媒體廣播伺服器60。 Referring to FIG. 6, the point-to-point online broadcast system includes: a multimedia broadcast server 60 coupled to a multimedia server 50 for obtaining multimedia materials; and a plurality of user terminals 70 and a multimedia broadcast server 60. A peer-to-peer network connection architecture is formed in which a plurality of user terminals 70 are connected to each other via a network and directly or indirectly connected to the multimedia broadcast server 60.
上述多媒體線上廣播之網路架構所採用的兩種網路系統中，主從式網路系統主要係由多媒體廣播伺服器60提供網頁介面(web)或專門軟體以接收用戶終端機70對多媒體資料的收聽請求指令，並依據用戶終端機70的收聽請求指令，將對應的多媒體資料以串流的方式輸出予對應用戶終端機70，現有如ShoutCast及IceCast兩種線上廣播軟體即採用主從式網路架構，然而此架構中，所有用戶終端機70皆必須連結至同一多媒體廣播伺服器60取得多媒體資料，若多媒體廣播伺服器60異常中斷連線，則所有用戶終端機70將無法存取多媒體資料，且多媒體廣播伺服器60的傳輸頻寬將由所有用戶終端機70共同分享，一旦太多人同時連線，易造成網路癱瘓，故此網路架構中，用戶終端機70的連線數量受限。 Among the two network systems used in the above-mentioned multimedia online broadcast network architecture, the master-slave network system mainly provides a web interface (web) or special software by the multimedia broadcast server 60 to receive the user terminal 70 to the multimedia material. Listening to the request command and outputting the corresponding multimedia data to the corresponding user terminal device 70 in a streaming manner according to the listening request command of the user terminal 70. The existing online broadcast software such as ShoutCast and IceCast adopts a master-slave network. In the architecture, all user terminals 70 must be connected to the same multimedia broadcast server 60 to obtain multimedia data. If the multimedia broadcast server 60 is abnormally disconnected, all user terminals 70 will not be able to access multimedia data. The transmission bandwidth of the multimedia broadcast server 60 will be shared by all the user terminals 70. Once too many people are connected at the same time, it is easy to cause network congestion. Therefore, the number of connections of the user terminal 70 is limited in the network architecture. .
點對點網路架構中，各個用戶終端機70從多媒體廣播伺服器50中取得多媒體資料後，便成為一個提供多媒體資料的中繼點，開始提供其他用戶終端機70多媒體資料，現有如PeerCast或P2P-Radio即採用此網路系統，雖然可分散多媒體廣播伺服器60流量，並減少多媒體廣播伺服器60中斷連線造成所有用戶終端機斷線的風險，但點對點網路系統會要求各個用戶終端機電腦開放其他用戶終端機電腦連線取得資料，因此資訊安全性相當低，許多用戶為之卻步，因此上述多媒體線上廣播之網路架構所採用的兩種網路系統皆仍非最佳化。 In the peer-to-peer network architecture, after each user terminal 70 obtains multimedia data from the multimedia broadcast server 50, it becomes a relay point for providing multimedia data, and starts to provide multimedia data of other user terminal devices 70, such as PeerCast or P2P- Radio uses this network system. Although it can distribute the multimedia broadcast server 60 traffic and reduce the risk of disconnection of all user terminals caused by the interruption of the multimedia broadcast server 60, the peer-to-peer network system requires each user terminal computer. Open other user terminal computers to obtain data, so the information security is quite low, many users are deterred, so the two network systems used in the above-mentioned multimedia online broadcast network architecture are still not optimized.
有鑑於上述多媒體線上廣播系統中，採用主從式網路架構者，其流量承載十分有限，且唯一一台多媒體廣播伺服器會產生單點失效之問題，採用點對點網路架構者，則使用戶終端機資訊安全性低之技術缺陷，本發明的主要目的係提出一種分散式多媒體線上廣播系統。 In view of the above-mentioned multimedia online broadcasting system, the master-slave network architecture adopts a very limited traffic load, and the only one multimedia broadcast server will have a single point of failure problem, and the point-to-point network architecture is used. The technical object of low security of terminal terminal information is that the main purpose of the present invention is to provide a distributed multimedia online broadcasting system.

According to the online information of the server and the data traffic of each cache server 12, the first few names with the smallest traffic are first selected from all the online cache servers 12, and then the cached servers 12 are randomly selected. Select one to connect, for example, first filter out the top three cache servers 12 with the smallest traffic, and then randomly select a cache server 12 to connect them, so that the distribution of traffic is more even.
誠如上述，該資料庫伺服器23將儲存有各多媒體廣播 伺服器11、快取伺服器12在線狀況的伺服器在線資訊，以及各多媒體廣播伺服器11的多媒體資料目錄，故連結至該資料庫伺服器23的多媒體廣播伺服器11、快取伺服器12皆可獲得各個伺服器是否在線以及各多媒體廣播伺服器11的多媒體資料目錄，如此，請進一步參閱圖3，上述分散式多媒體線上廣播系統載運作時，若複數網頁伺服器13分別接收到不同的收聽請求指令，分別請求讀取曲名(1)、曲名(2)及曲名(5)三個多媒體資料，則各網頁伺服器13係依據伺服器在線資訊隨機選擇其中一在線的快取伺服器12進行連結，如圖中所示表示所有快取伺服器12及所有多媒體廣播伺服器11均在線，而各快取伺服器12依據收聽請求指令、伺服器在線資訊及各多媒體廣播伺服器11的多媒體資料目錄，得知在線的多媒體廣播伺服器11中，哪些多媒體廣播伺服器11的多媒體資料目錄中有收聽請求指令所需的多媒體資料，並連結至對應的多媒體廣播伺服器11，取得收聽請求指令所需的多媒體資料，透過網頁伺服器13傳輸予用戶終端機70，如此即可達成分散流量之目的。 As mentioned above, the database server 23 will store various multimedia broadcasts. The server 11 and the server online information of the cache server 12 and the multimedia data directory of each multimedia broadcast server 11 are connected to the multimedia broadcast server 11 and the cache server 12 of the database server 23. Whether the respective servers are online and the multimedia data directory of each multimedia broadcast server 11 can be obtained. Therefore, please refer to FIG. 3, when the distributed multimedia online broadcast system is in operation, if the plurality of web servers 13 receive different Listening to the request instruction, respectively requesting to read three multimedia materials of the music name (1), the music name (2) and the music name (5), the web server 13 randomly selects one of the online cache servers 12 according to the online information of the server. Linking, as shown in the figure, indicates that all cache servers 12 and all multimedia broadcast servers 11 are online, and each cache server 12 is based on the listening request command, the server online information, and the multimedia of each multimedia broadcast server 11. The directory of the data, and in the multimedia broadcast server 11 of the online, which multimedia broadcast server 11 has the multimedia data directory Listening to the multimedia data required for the request, and connecting to the corresponding multimedia broadcast server 11, obtaining the multimedia data required for the listening request command, and transmitting the multimedia data to the user terminal 70 through the web server 13, so that the purpose of distributing the traffic can be achieved. .
再請進一步參閱圖4，當有其中一快取伺服器12’及其中一多媒體廣播伺服器11’當機或斷線時，上述訂位伺服器22將於周期性發送資訊支持事件後，不再收到已當機或斷線的多媒體廣播伺服器11’及快取伺服器12’回覆訊息，進而更新該資料庫伺服器23中的伺服器在線資訊，無回覆訊息的多媒體廣播伺服器11’及快取伺服器12’將被標示為離線或刪除，此後所有的網頁伺服器13在選擇快取伺服器12時，便不會選到當機或斷線的快取伺服器12’，而在線的快 取伺服器12在選擇多媒體廣播伺服器11時，也會避開當機或斷線的多媒體廣播伺服器11’，因此，當網路中所有伺服器的連線狀況皆正常(如圖3)，若突然有多媒體廣播伺服器11’或快取伺服器12’斷線，則原本透過這些多媒體廣播伺服器11’或快取伺服器12’取得多媒體資料的用戶終端機70將先發生連結中斷，而此用戶終端機70只要重新連結網頁，網頁伺服器13及快取伺服器12便可避開已斷線的多媒體廣播伺服器11’及快取伺服器12’，重新選到適當的連線，取得所需的多媒體資料，得以避免資料傳輸系統中產生單點失效的問題，且用戶終端機70不必更改使用習慣。 Referring to FIG. 4 again, when one of the cache servers 12' and one of the multimedia broadcast servers 11' is down or disconnected, the reservation server 22 will periodically send an information support event, Then, the multimedia broadcast server 11' and the cache server 12' that have been disconnected or disconnected are received, and the server online information in the database server 23 is updated, and the multimedia broadcast server 11 without replying the message is received. 'And the cache server 12' will be marked as offline or deleted. After that, all the web server 13 will not select the crashed or disconnected cache server 12' when selecting the cache server 12. And online fast When the multimedia server 10 is selected, the server 12 also avoids the offline or disconnected multimedia broadcast server 11'. Therefore, when all the servers in the network are connected, the connection status is normal (see Figure 3). If the multimedia broadcast server 11' or the cache server 12' is suddenly disconnected, the user terminal 70 that originally obtained the multimedia data through the multimedia broadcast server 11' or the cache server 12' will be disconnected first. If the user terminal 70 reconnects to the webpage, the web server 13 and the cache server 12 can avoid the disconnected multimedia broadcast server 11' and the cache server 12', and reselect the appropriate connection. The line, the required multimedia material is obtained, to avoid the problem of single point failure in the data transmission system, and the user terminal 70 does not have to change the usage habit.
除此之外，上述的網路架構可依據所需的資料流量來決定所需的伺服器個數，當用戶越來越多時，僅需增加網頁伺服器13、快取伺服器12及多媒體廣播伺服器11的數量即可，不必更改整體架構，其架構的擴展較有彈性(flexible)。 In addition, the above network architecture can determine the number of servers required according to the required data traffic. When more and more users, only need to add web server 13, cache server 12 and multimedia. The number of broadcast servers 11 is sufficient, and the overall architecture does not have to be changed, and the expansion of the architecture is flexible.
綜上所述，上述分散式多媒體線上廣播系統不需透過用戶終端機互相傳輸資料，以在確保用戶資訊安全的前提下，提供資料傳輸分流，並自動避開斷線的伺服器來進行資料傳輸，得以分散資料流量、增加可容納的用戶終端機連線數量且避免資料傳輸的單點失效問題。 In summary, the above-mentioned distributed multimedia online broadcasting system does not need to transmit data to each other through the user terminal, so as to provide data transmission and distribution under the premise of ensuring user information security, and automatically avoid the disconnected server for data transmission. It is able to disperse data traffic, increase the number of user terminals that can be accommodated, and avoid single-point failures in data transmission.
