Abstract: The disclosure provides a load balancing system, a load balancing device and a topology management method. The topology management method includes configuring and maintaining a transmission progress value for each of edge servers; grouping the edge servers into server groups, wherein the edge servers of each of the server groups provide one of a plurality of video streams, and each of the edge servers is grouped into at least one server group among the server groups; selecting a first video stream from at least one video stream corresponding of a first edge server having bandwidth usage rate higher than a high load threshold; synchronizing video data of the first video stream to a second edge server; setting a transmission progress value of the second edge server as a transmission progress value of the first edge server; and adding the second edge server into the server group corresponding to the first video stream.

Abstract: The disclosure provides a load balancing method, a load balancing system, a load balancing device and a topology reduction method. The load balancing method includes configuring a transmission progress value for each of the edge servers; grouping the edge servers into server groups, wherein each of the edge servers is grouped into at least one server group among the server groups; receiving a download request corresponding to a first video stream from a user device, wherein a first server group among the server groups provides the first video stream; and selecting one of the edge servers from the edge servers of the first server group as a first edge server to provide video data of the first video stream to the user device according to the transmission progress values of the edge servers of the first server group.

Abstract: A buffer and output method and a buffer module for a multimedia stream are provided, wherein multimedia stream packets are received and stored into a first buffer, and when an actual remaining time calculated according to an accumulated idle time and a buffer time, is greater than a remaining time threshold value, following steps are performed. A first present time is read, and a sleep instruction is executed, so as to wait for a preset idle time. A second present time is read, and an actual idle time different from the preset idle time is calculated according to the first present time and the second present time. A part of buffer units are enabled according to the accumulated idle time accumulated according to the actual idle time, to output the stored multimedia stream packets to a second buffer of a player.
