步驟S33,連線管理模組102從虛擬機31的連線信息列表中選擇客戶端設備2所需使用之虛擬機畫面對應之虛擬機31。於本實施例中,使用者可藉由連線管理模組102從顯示在客戶端設備2上之連線信息列表中選擇所需使用之虛擬機畫面對應之虛擬機31。例如,使用者根據需求可以選擇主機3中的虛擬機VM1或VM2作為客戶端設備2所需使用之虛擬機畫面對應之虛擬機31。In step S33, the connection management module 102 selects the virtual machine 31 corresponding to the virtual machine screen used by the client device 2 from the connection information list of the virtual machine 31. In this embodiment, the user can select the virtual machine 31 corresponding to the virtual machine screen to be used from the connection information list displayed on the client device 2 by the connection management module 102. For example, the user can select the virtual machine VM1 or VM2 in the host 3 as the virtual machine 31 corresponding to the virtual machine screen used by the client device 2 according to requirements.
步驟S34,連線管理模組102判斷中央伺服器1是否與選擇之虛擬機31建立通訊連接。若中央伺服器1還未與選擇之虛擬機31建立通訊連接,則執行步驟S35;若中央伺服器1已與選擇之虛擬機31建立通訊連接,執行步驟S36。In step S34, the connection management module 102 determines whether the central server 1 establishes a communication connection with the selected virtual machine 31. If the central server 1 has not established a communication connection with the selected virtual machine 31, step S35 is performed; if the central server 1 has established a communication connection with the selected virtual machine 31, step S36 is performed.
步驟S35,連線管理模組102根據主機3的IP位址及虛擬機31的端口號將中央伺服器1與選擇之虛擬機31建立通訊連接。每一個主機3中之虛擬機31均具有一個唯一的端口號,例如,主機3中VM1的端口號為6000,例如VM2的端口號為6001等。In step S35, the connection management module 102 establishes a communication connection between the central server 1 and the selected virtual machine 31 according to the IP address of the host 3 and the port number of the virtual machine 31. The virtual machine 31 in each host 3 has a unique port number. For example, the port number of VM1 in the host 3 is 6000, for example, the port number of the VM2 is 6001.
步驟S36,畫面獲取模組103透過被選擇之虛擬機31對應之虛擬機管理器32從該虛擬機31中獲取虛擬機畫面資料。所述之虛擬機畫面資料包括虛擬機影像畫面及語音訊息等資料,其可播放並顯示在所述之客戶端設備2上。In step S36, the screen acquisition module 103 acquires the virtual machine screen data from the virtual machine 31 through the virtual machine manager 32 corresponding to the selected virtual machine 31.

步驟S37,畫面獲取模組103將獲取之虛擬機畫面資料透過網路4發送給所述之客戶端設備2,並將該虛擬機畫面資料播放並顯示在該客戶端設備2上,以供使用者使用。In step S37, the screen obtaining module 103 sends the acquired virtual machine screen data to the client device 2 through the network 4, and plays and displays the virtual machine screen data on the client device 2 for use. Use.
步驟S38,斷線管理模組104判斷是否有其他客戶端設備需要顯示該虛擬機畫面資料。若其他客戶端設備需要顯示該虛擬機畫面資料,則流程返回步驟S37;若無其他客戶端設備需要顯示該虛擬機畫面資料,則流程執行步驟S39。In step S38, the disconnection management module 104 determines whether there are other client devices that need to display the virtual machine screen data. If the other client device needs to display the virtual machine screen data, the process returns to step S37; if no other client device needs to display the virtual machine screen data, the process proceeds to step S39.
步驟S39,斷線管理模組104將中央伺服器1與所選擇之虛擬機31斷開通訊連接,以便釋放虛擬機畫面資料所佔用主機3之網路寬頻資源。In step S39, the disconnection management module 104 disconnects the central server 1 from the selected virtual machine 31 to release the network broadband resources of the host 3 occupied by the virtual machine picture data.
最後需要說明的是,假設客戶端User1想連線到主機3中的虛擬機VM3便可直接在客戶端設備2顯示的連線信息列表中點選虛擬機VM3,由中央伺服器1連線至192.168.0.2:6000以VNC協議連線密碼為345678,便可以取得虛擬機VM3的畫面資料,並將該畫面資料給客戶User1。此時,若客戶端User2也想連線到主機3中的虛擬機VM3,由於中央伺服器1已與連線至192.168.0.2:6000取得虛擬機VM3的畫面資料了,因此便不需要再連線一次,僅需要將相同給與客戶端User1的VM3畫面資料複製一份給客戶端User2即可,由此將主機3的頻寬需求降低至一個畫面資料轉嫁到中央伺服器1上,進而降低主機3的網路頻寬使用率及其工作負荷。Finally, it should be noted that, assuming that the client User1 wants to connect to the virtual machine VM3 in the host 3, the virtual machine VM3 can be directly selected in the connection information list displayed by the client device 2, and connected by the central server 1 to 192.168.0.2:6000 with the VNC protocol connection password is 345,678, you can get the virtual machine VM3 screen data, and the screen information to the customer User1. At this time, if the client User2 also wants to connect to the virtual machine VM3 in the host 3, since the central server 1 has connected to the 192.168.0.2:6000 to obtain the screen data of the virtual machine VM3, there is no need to connect again. Once the line is needed, it is only necessary to copy the same VM3 screen data given to the client User1 to the client User2, thereby reducing the bandwidth requirement of the host 3 to a picture data and transferring it to the central server 1, thereby reducing Host 3's network bandwidth usage and its workload.
