The invention discloses a management method of a cache of an SAN (Storage Area Network), which is characterized by realizing the access control on the cache data of VSS (Volume Shadow Copy Service) in the SAN. The management method comprises the following steps of: transmitting snapshot data to a cache of a volume shadow copy server by the SAN; adjusting the data writing-in speed of a block device to be less than data writing-in cache speed; detecting the cache capacity and judging whether the data in the cache are written into the block device or not; and repeating the read-write motion of the cache until the establishment of snapshot volumes is accomplished.

The invention discloses a networking backup system which comprises a document uploading module, a document receiving module, a storage index module, a document recording module, a magnetic disk storage module and a document caching module, wherein the document uploading module is used for calculating a MD5 value of a document and transmitting the document from a client to a server; the document receiving module is used for receiving the document content uploaded by the document uploading module and the MD5 value calculated by the document uploading module and storing the document record; the storage index module is used for recording the MD5 characteristic information of different documents for indexing by the document receiving module; the document recording module is used for recording the original recording information of the uploading document; the magnetic disk storage module is used for storing the document content; the document caching module is used for caching the compressed files of the frequently downloaded applications. The networking backup system can utilize a document fingerprint technique to eliminate the redundant documents in the document storage on the server side and can save the server-side magnetic disk space. The invention also discloses a networking backup method.

The invention relates to a method for processing signal and relative device. Wherein, it is characterized in that: processing advanced detection on received baseband signal, to output detected effective multi-path information; based on said information, processing judgment, and according to the result of judgment, distributing the multi-path information that need demodulation; based on distributed multi-path information, selecting the signal of relative branch to be demodulated and decoded. The invention can directly process demodulation and filtration on received baseband signal, without storing long demodulate data to correct the signal deflection, to reduce the time delay of memory resource and data treatment. In addition, the invention processes information demodulation on the total branches with effective multi-path information, after the advanced detection, to avoid the decrease of demodulation property caused by mistake selection of demodulate branch, to confirm the access property of signal.

The invention discloses a channel distribution method for temporary block flow. The method comprises the steps of obtaining the seizure rate of TFI resources of current PDCH sets of a cell when the TBF is established, adding the PDCH sets when the seizure rate of the TFI resources exceeds a set first threshold, and distributing the established TBF to the added PDCH sets; when the PDCH sets are not added, distributing the established TBF to the PDCH set with the lowest loading efficiency; adjusting the number of PDCHs in the PDCH sets according to the loading efficiencies of the PDCH sets. The invention further discloses a channel distribution device for the temporary block flow at the same time. By means of the channel distribution method for the temporary block flow and the channel distribution device for the temporary block flow, the number of the PDCHs distributed to the cell can be adjusted dynamically, the utilization rate of the wireless resources is increased, and meanwhile, the situation that a service request does not have access due to the fact that only the loading efficiency is considered is avoided.

The invention discloses a method utilizing current internet data and service, belonging to the integrated application of a distributed technology in an internet system. The method comprises the following steps: firstly requiring to establish a peer-to-peer server mainly aiming at devoting self source; endowing the server with the ability of converting current internet data and service, namely obtaining data and service through being communicated with the current internet, and utilizing the data and service in a mode accepted by a large-scale non-center internet. In the process, the peer-to-peer server peers and diverges the current internet server to ensure that the operation mode of the current internet server is in conformity with that of the peer-to-peer server from the view of a user'the peered and diverged internet server is added into a corresponding channel in a manual or automatic mode to ensure that the internet server can receive accession with ambiguous range and is easy to generate stream. The current internet engine also can be utilized and reformed progressively by using similar methods. The method takes full advantages of current internet data, service and computing resource to enable the current internet to organically combine with the large-scale non-center internet, thus changing the disadvantages of the current system and devoting source thereof to novel internet.

An embodiment of the invention discloses a resource allocation method. The method is applied to a Cache shared by multiple processors. The Cache comprises a Cache controller and Cache registers; and the Cache registers include a statistical register corresponding to each processor and a lock register corresponding to each processor. The method comprises the steps that each statistical register performs statistics on Cache capacity accessed by the processor corresponding to each statistical register in a preset time, obtains Cache access capacity of each processor, and sends the Cache access capacity of each processor to the Cache controller; the Cache controller determines Cache allocation capacity of each processor according to the Cache access capacity of each processor; and the Cache controller writes the Cache allocation capacity of each processor in the lock register corresponding to each processor. Meanwhile, an embodiment of the invention furthermore discloses the Cache.

The invention discloses a data access component. The data access component comprises a data access interface, a model mapping component, model adapters and a query and command arrangement component, the model mapping component is used for connecting the data access interface and each model adapter; the model adapters are used for directly operating the databases connected with the model adapters, and the model adapters are in one-to-one correspondence with the various databases; and the query and command arrangement component is used for analyzing the query statements and automatically routing the query statements to the database with the highest efficiency for query operation. According to the data access component, multi-element storage and multi-element access of data can be guaranteed, and certain access performance can be guaranteed through automatic routing.
