4. Suppose server S want to download real time video from one of existing media servers A, B, C, D. However the server S still doesn't know which media server is available and can provide the highest speed transfer. Please write a simple code to make the server S chooses the fastest server using below function: a. int get_speed(ServerID); This function is used to get the transfer speed from Server[ServerID] to server S on HTTP protocol. The return value of this function is integer value. For example: get_speed(A) return 15, it means the transfer speed is 15 Kbps. b. bool connect(server); This function is to check the availability of the media server using RMTP (Real Time Message Protocol). This function will return true if the media server have the video source that can be streamed by server S. For example: connect(A) return true, it means server S can stream video from server A. Hint: get_speed(serverID) function only check the transfer speed of the media server using normal HTTP. It doesn't guarantee the media server is available. Example: Media Server A may provide the highest transfer speed, however there is no video source available in media server A. So in this case, server B may connect to other server 这是小弟在网路上看到的题目 是一间公司考新人用的题目 小弟对於这方面可说下外行 不知是否有高人知道要如何解 --
