摘要： A method and apparatus for providing a peer-to-peer (P2P) based streaming service are provided. The method provides a streaming service in a peer-to-peer (P2P) network comprising a plurality of peers. That is, a receiving peer requests a plurality of transmitting peers having contents for a streaming service among peers in the P2P network to transmit the contents. Then, the receiving peer receives identical portions of the same content from the plurality of transmitting peers at the same time. After receiving, the receiving peer provides a streaming service for the received content from a first transmitting peer among the plurality of transmitting peers to a user.

摘要： A file level striping method adds an option for indicating whether or not to support file level striping to a file creation interface in a file system, extends an inode structure to include a last disk ID field, initializes the last disk ID when the file is created in the file system, allocates a physical block based on the last disk ID when the physical block allocation is requested at the time of file I/O request in the file system, and modifies the last disk ID value to reflect the physical block allocation made by a volume manager. An apparatus using the file level striping method includes a number of disks for storing information actually, the volume manager for logically grouping a number of disks and a file system for creating files on said logical volume and performing I/O operations.

摘要： A fractional caching method and an adaptive contents transmitting method using the same are provided. The fractional caching method includes the steps of setting up a divided location for dividing a certain object into two parts, receiving an evict request for acquiring a space in the inside of the cache, when the evict request is transmitted, dividing a plurality of objects stored in the cache into a prefix-Object located in the head of the object and a suffix-Object located in the tail of the object from the divided location, and removing only the suffix-Object of each object, wherein the divided location is set up at a size rate that a size of the prefix-Object is in inverse proportion to the number of the destination types.

摘要： A method of data placement and control in a block-divided distributed disk array is provided. At first, data to store is divided into logical blocks, and each of the divided logical blocks is further divided into a plurality of data blocks. Then, a parity block is created through performing an XOR operation on the data blocks of each logical block in a unit of a strip, and the parity block is arranged at the first block of a strip unit. Then, parity blocks are arranged at a next block of a previous logical block's the last data block through a left/right shifting for uniformly arranging the parity blocks through out all disks in order to fill an empty block between the logical blocks.
