Abstract: A data manipulation method of a logical volume manager is applicable to data management of dependent snapshot volumes (SVs) of a logical volume manager. The data management method includes the following steps generating a plurality of SVs, defining the SV generated at first as a first SV, defining the SV generated at last as a last SV, and defining the rest SVs as middle SVs; selecting a middle SV; combining content stored in the selected middle SV into a neighboring SV; according to the combined SV, combining meta-data of the selected middle SV into meta-data of the middle SV; deleting the selected middle SV. The logical volume manager does not need copy the data again, thereby saving access time in data management.

Abstract: A method of dynamically adjusting the number of task requests is provided, which is applicable to an Internet Small Computer System Interface (iSCSI) protocol. When a target receives a task request transmitted by an initiator or the target completes the task request, the number of transmissible tasks is calculated according to an average access data volume, an current access data volume, and an allowable access data volume in the target, and returned to the initiator, such that the number of the task requests transmitted simultaneously by the initiator does not exceed the number of transmissible tasks, thereby achieving flow control. The allowable access data volume is obtained through interactive and dynamic adjustment between the target and the initiator.

Abstract: A network card testing method, used to test if the network card is capable of functioning normally in a computer having Extended Firmware Interface (EFI) system. Wherein, in a protocol assignment table is recorded the connection relations of a network protocol of Extended Firmware Interface, and a driver program corresponding to a network driver interface specification (NDIS) layer.

Abstract: A method of updating intrusion detection rules through a link data packet is used to dynamically update rules storages of Snort system hosts. Firstly, an update sponsor in the network transmits a link data packet with an intrusion detection rule to the Snort system host. The Snort system host acquires the intrusion detection rule from the received link data packet, and parses an operation type of the intrusion detection rule. Then, the Snort system host verifies the validity of the intrusion detection rule. Subsequently, the rules storage is updated according to the type of the valid intrusion detection rule and a rules tree.
