Abstract: Embodiments relate to a method for transmission of content, executed by a content transmission device. The method includes receiving, from a client device, a content request specifying a requested content and at least one content reception deadline in an application layer part, encapsulating the requested content in a plurality of successive TCP segments; and sending the successive TCP segments to the client device by applying a congestion avoidance mechanism using a congestion window, The congestion window is determined by determining a minimum bitrate required for transmitting the requested content to the client device by the content reception deadline, determining a round-trip time between the content transmission device and the client device, and setting the congestion window equal to or greater than the product of the minimum bitrate and the round-trip time.

Abstract: A rack server system management method adapted in a rack server system is provided. The rack server system management method comprises the steps as follows. The first information of a plurality of servers in the rack server system and the second information of a plurality of fan modules in the rack server system are updated every predetermined time period by a document management unit. A rack management module retrieves the first and the second information through polling the document management unit. The rack management module retrieves temperature values of the servers from the first information and adjusts the speed of the fan module according to the second information. A rack server system is disclosed herein as well.

Abstract: A rack server system is provided. The rack server system includes a plurality of server modules, a plurality of fan modules, a rack management network and a rack management module. Each of the server modules comprises a baseboard management controller (BMC) to monitor and manage a work status of the corresponding server module. Each of the fan modules includes a plurality of fans. The rack management network is connected to the BMC of each server module. The rack management module receives the work status from the BMC of each server module through the rack management network to control and manage the server modules and to control speed of the fan modules.

Abstract: A data center is provided. The data center includes a plurality of racks, a container management network and a container management module. Each of the racks includes a rack management module and a plurality of server modules. The rack management module is used for receiving an operation status of the corresponding server module. The container management network is connected to the rack management module and the server module. The container management module is connected to each rack through container management network to receive the operation status for controlling and managing each rack according to the operation status.
