Data reading-writing method and device for remote data storage and system thereof

The invention discloses a data writing method for realizing remote data storage, which comprises the following steps: receiving a data writing request and requested write-in data; according to parameters used for determining sector numbers in the data writing request, determining the sector numbers which respectively correspond to all sectors used for storing the requested write-in data; respectively executing by aiming at each determined sector number; according to corresponding relations aiming at the block device identification-marked sector numbers of block device maintenance and marker bits in the data writing request, setting the marker bits which correspond to the sector numbers, wherein sectors marked by the sector numbers which correspond to the unset marker bits are used for storing the raw data of a block device or do not store the data, and the sectors marked by the sector numbers which correspond to the set marker bits are used for storing updated data of the block device; according to block device identifications, the sector numbers and arrow marks used for pointing to the updated data of the block device, generating corresponding key values; and correspondingly storing all the generated key values and the requested write-in data to remote storage resource pools.

Multimedia live broadcast whistle-blowing method, terminal, server and system

The invention discloses a multimedia live broadcast whistle-blowing method, terminal, server and system, and belongs to the technical field of information. The method comprises the steps that a whistle-blowing instruction is obtained, and media data are obtained from multimedia data broadcast in a media broadcast interface within the preset time period according to the whistle-blowing instruction; whistle-blowing information is determined according to the media data, wherein the whistle-blowing information at least comprises the media data and the broadcast information of the media data, and the broadcast information of the media data comprises the information identifying the source of the media data; the whistle-blowing information is uploaded to a whistle-blowing server. According to the multimedia live broadcast whistle-blowing method, due to the facts that the media data are obtained from the multimedia data broadcast in the media broadcast interface within the preset time period according to the whistle-blowing instruction, the whistle-blowing information determined according to the media data is uploaded to the whistle-blowing server, and the whistle-blowing server processes the whistle-blowing information, whistle-blowing information is rapidly uploaded, occupied network resources are reduced, and the supervision range of multimedia live broadcast is enlarged.

Method and system of fast file updating applied to cloud storage

ActiveCN103166992AFast uploads and updatesReduce occupancyTransmissionClient-sideCloud storage
The invention relates to a method and a system of fast file updating applied to cloud storage. The method of fast file updating applied to the cloud storage comprises steps as below: a client terminal submits an inquiry requirement of information of files needing to be updated to a cloud storage server; the cloud storage server returns file fragmentation metadata of the files needing to be updated according to the inquiry request of the information of the files; the client terminal compares the file fragmentation metadata; the client terminal determines the file fragmentation metadata for updating according to the data comparison result; the client terminal uploads the file fragmentation metadata and the fragmentation data to the cloud storage server; the cloud storage server updates the corresponding file fragmentation metadata of the files needing to be updated. The invention relates to the system of fast file updating applied to cloud storage. During the uploading and updating process of the files, inquiry and comparison are carried out at first to determine the file fragmentation which is changed, and therefore only the file fragmentation which is changed is uploaded, fast uploading and updating of the files is achieved, and occupation of system resources and network resources is low.

Detection-based fault diagnosis method and system of service function chain

The embodiment of the invention provides a detection-based fault diagnosis method and system of a service function chain. The method comprises the following steps: acquiring a network topological graph of a virtual network; determining at least one detection starting node according to the in-degree and the out-degree of a service function node in the network topological graph; traversing the network topological graph through the multiple detection starting nodes to generate multiple detection paths; respectively sending an active detection packet to multiple detection paths through the detection starting nodes so as to obtain a detection result of the active detection packet; and diagnosing a fault detection path in the multiple detection paths and a fault SFC in the SFC according to the detection result of the active detection packet. Through the adoption of the detection-based fault diagnosis method and system of the service function chain provided by the embodiment of the invention, the whole network can be detected by use of small detection flow, thereby lowering the occupation degree of the network bandwidth. And the time delay of the service function node and the logic link in the SFC can be judged according to the timestamp in the active detection packet, so that the diagnosis result is more accurate.

System and method for positioning failures of communication network equipment based on alarm information

The embodiment of the invention discloses a system and a method for positioning failures of communication network equipment based on alarm information. The method comprises the following steps that a resource management system synchronizes the stored related resource information of various kinds of communication network equipment and bearer circuits in a communication network to a middle base unit according to a preset period; the middle base unit converts the synchronized related resource information according to the requirements of a comprehensive alarming system on the format of alarm position information by using preset conversion rules, and transmits the converted related resource information to the comprehensive alarming system; the comprehensive alarming system stores the converted related resource information in a local database, performs resource association when receiving the alarm information, acquires the related resource information associated with the alarm position information in the alarm information from the local database, and displays the acquired related resource information on an alarm detail interface. According to the embodiment of the invention, the alarm position can be rapidly and accurately determined.
