    • According to one embodiment, a server includes a transmitter, a storage, a determination unit and a controller. The transmitter is configured to transmit data using TCP streams. The storage is configured to store a number of TCP streams which the transmitter used in transmitting the data and a maximum value of a bandwidth which the transmitter used in transmitting the data using the number of TCP streams, in association with each other. The determination unit is configured to determine a number of TCP streams, which the transmitter uses in transmitting new data, based on the stored number, the stored maximum value, and a target value of the bandwidth. The controller is configured to update the stored maximum value when a bandwidth used for transmitting the new data using the determined number is larger than the maximum value associated with the stored number which is identical to the determined number.
    • 根据一个实施例,服务器包括发射机,存储器,确定单元和控制器。 发射机被配置为使用TCP流传输数据。 存储器被配置为存储发送机用于发送数据的多个TCP流,并且使用TCP数量的数据相关联地存储发送机用于发送数据的带宽的最大值。 确定单元被配置为基于存储的数量,存储的最大值和带宽的目标值来确定发送机用于传输新数据的TCP流的数量。 控制器被配置为当用于使用确定的数量发送新数据的带宽大于与所确定的数量相同的存储号码的最大值时,更新存储的最大值。

    • There is provided with a method of performing in a server apparatus sharing an image to be displayed on a screen with a client terminal, including: updating a part of an image in a frame buffer; generating a first packet which includes first area information indicating a first area updated in the image, a first image which is an image after update in the first area and a sequence number assigned by a sequence number counter and transmitting it; storing a set of the first area information and the sequence number in a storage; receiving a retransmission request including a sequence number from the client terminal; detecting a second area which is not updated in the first image which corresponds to the sequence number included in the retransmission request after the transmission of the first image by referring to the storage; acquiring a second image in the second area from the frame buffer.
    • 提供了一种在服务器装置中执行与客户终端共享要显示在屏幕上的图像的方法,包括:更新帧缓冲器中的图像的一部分; 产生第一分组,其包括指示图像中更新的第一区域的第一区域信息,作为在第一区域中更新之后的图像的第一图像和由序列号计数器分配并发送的序列号; 将一组第一区域信息和序列号存储在存储器中; 从所述客户终端接收包括序列号的重传请求; 通过参照该存储,检测在发送第一图像之后,重新发送请求中包含的与序列号对应的第一图像中未更新的第二区域; 从帧缓冲器获取第二区域中的第二图像。
