摘要： Provided sets a limit of execution threads which can be simultaneously processes in an input/output system and compares the number of threads which are being currently executed with the limit of execution threads at the time of requesting an input/output event from a thread and manages a job of processing the input/output event in accordance with the comparison result. The apparatus for asynchronous input/output processing of a multi-thread according to the present invention restricts the number of threads which are processed in the asynchronous input/output system as many as the limit of execution threads to prevent deterioration of performance caused due to context switching overhead of the thread and efficiently manage the thread.

摘要： Provided is an apparatus and method for automatically generating a SELinux security policy based on SELT. In the method, process generation is prepared by receiving execution file names of a program destined for policy generation. A system call log, which is traced by generating a process by executing the received execution file of the program, is stored. The traced system call log is purified into data necessary for generation of a security policy. Objects are grouped in consideration of the relationship between the objects based on purified information. A normalized data structure is recorded in an SELT description language format using a security policy file. Duplication and collision between the generated SELT security policy and the previous security policy in a system are detected.

摘要： The present invention propose a new mechanism, IP check layer which enables to use TOE cards and legacy NICs simultaneously within same protocol family in a Linux or a UNIX computing environment. The IP check layer is inserted between a BSD socket layer and an INET socket layer. IP check layer maintains a routing information and, information of IP addresses of each network interfaces and each socket's bind state. Using this information, IP check layer determines how to process a socket call and which layer (TOE layer, host INET layer) will take over the socket call. By means of the above mechanism, the present invention makes existing socket applications to use TOE cards and legacy NICs at the same time without modification or recompiling.

摘要： There is provided a socket compatibility layer for a TOE in a high quality server system. The socket compatibility layer for a TOE provides a standard socket API to an application program and provides binary-level compatibility so that a networking function of a TOE can be used without modifying the conventional socket application program thereby supporting simultaneous use of a TOE and a general Ethernet-based NIC. In a kernel structure of the Linux operation system, the socket compatibility layer for a TOE is located below a BSD socket layer receiving a socket system call from an application program through a standard socket API, is located above an INET socket layer and a TOE driver to control connection between an upper layer and a lower layer, and transmits the socket system call received from the BSD socket layer to the TOE driver or the INET socket layer according to call contents of the socket system call. The socket compatibility layer for a TOE includes a TOE socket generation module, a virtual TOE socket, a TOE STREAM module unit and a TOE DGRAM module unit.

摘要： Provided are a network scheduler and a network scheduling method capable of effectively managing network bandwidths by selectively supporting a work conserving mode to network entities by using an improved token bucket scheme. The network scheduler selectively supports a work conserving mode to network scheduling units (NSUs) serving as network entities by using a token bucket scheme, such that the network scheduler ensures an allocated network bandwidth or enables the NSUs to use a remaining bandwidth. The network scheduler manages the NSUs by classifying the NSUs into a green state, a red state, a yellow state, and a black state according to a token value, a selection/non-selection of the work conserving mode, and an existence/non-existence of the packet request to be processed.

摘要： A log-based FTL and an operating method thereof for improving performances of reading and writing operations to increase the lifetime of a flash memory. In the method, when a reading operation for an LBN and an LPN is requested, a PBN and a PPN corresponding to the LBN and the LPN are calculated with reference to a pagemap corresponding to the LBN. A physical page of a physical block corresponding to the PBN and the PPN is accessed so that a reading operation is performed. On the other hand, when a writing operation for the LBN and the LPN is requested, a PBN and a PPN for a free-page of a physical block last assigned for the LBN are calculated with reference to a blockmap. The physical page of the physical block corresponding to the PBN and the PPN is accessed, so that a writing operation is performed. The pagemap stores a PBN and a PPN, and the blockmap stores a PBN list and a PPN.
