Abstract: PURPOSE: A buffer management system and method is provided to perform an integrated management of individual buffer at a host computer networked with other host computers, and to support a transmission of contents at the buffer among the host systems so that the host systems can conceptually share the buffers with one another. CONSTITUTION: The system comprises a plurality of individual buffer managers, a global buffer manager, a plurality of individual locking managers, and a global locking manager. The individual buffer manager, installed at each host system, manages an individual list of data stored at a buffer directly connected to each host. The global buffer manager, installed at a global buffer server for performing an integrated management of the host systems, integrates data stored at the buffers connected to the host systems and manages a global list of the data. The individual locking manager, installed at each host, manages an individual list of current locking data of each host system. The global locking manager, installed at the global buffer server, manages a global locking list of data to be managed by the global buffer server.

Abstract: A mixed segment management method in a transcoding proxy and an apparatus thereof are provided to apply a mixed segment technique where equal and index size segment techniques are mixed, when offering contents. A transcoding proxy server(310) classifies contents into several versions according to the transmission rate, and applies an index segment technique, in which a segment is exponentially increased according to the version increase or reduction, to the contents. The transcoding proxy server applies an equal segment technique, which performs the division into the same size for a separate version. A client(320) selects the contents corresponding to a desired transmission rate among the versions.

Abstract: A method for accelerating speed of IO between a user memory and a disk by using a PCI memory is provided to access data at a high speed while a user program manipulates or refers to data by inputting or outputting directly data to or from the user memory. A method for accelerating speed of IO between a user memory and a disk comprises the following several steps. If a user program requests IO with respect to an arbitrary disk(S101), an internet server computing system determines a network storage card to which the disk is connected(S102) and assigns a PCI memory not used in the NS card(S103). The internet server computing system determines whether the IO request of the user program is read or write(S104). In case of the read IO request, the system reads data on a block of the disk, which requests the data IO, to the assigned PCI memory(S105). Then, the system transmits the data of the PCI memory to the user memory by using DMA(Direct Memory Access) of an IO process of the NS card(S106). In case of the write IO request, the system transmits data of the user memory to the assigned PCI memory by using the DMA(S107) and stores the data of the PCI memory at a block of the disk which requests the data IO(S108).
Abstract translation: 提供了一种通过使用PCI存储器来加速用户存储器和磁盘之间的IO速度的方法，以便在用户程序通过向用户存储器或从用户存储器直接输入数据或从用户存储器直接输入数据来进行数据输入或引用数据时高速访问数据。 用于加速用户存储器和磁盘之间的IO速度的方法包括以下几个步骤。 如果用户程序相对于任意的磁盘请求IO（S101），则互联网服务器计算系统确定连接了该磁盘的网络存储卡（S102），并分配NS卡中未使用的PCI存储器（S103）。 互联网服务器计算系统确定用户程序的IO请求是否被读取或写入（S104）。 在读取IO请求的情况下，系统将请求数据IO的磁盘块上的数据读取到所分配的PCI存储器（S105）。 然后，系统通过使用NS卡的IO处理的DMA（Direct Memory Access，直接存储器访问）将该PCI存储器的数据发送给用户存储器（S106）。 在写入IO请求的情况下，系统通过使用DMA将用户存储器的数据发送到所分配的PCI存储器（S107），并将PCI存储器的数据存储在请求数据IO的盘的块（S108） 。
