The invention discloses a blockchain-based intrusion detection system for railway signal, which is built on a blockchain's distributed chain structure, without a central, trusted control center. This design mitigates the vulnerabilities associated with centralized intrusion detection centers. Additionally, by utilizing a blockchain-based distributed structure, it also eliminates the risk of a single point of failure for the intrusion detection center. Moreover, the data within the blockchain-based intrusion detection system is highly resistant to malicious tampering. This is achieved by leveraging the consensus mechanism inherent in the blockchain, which can achieve consensus among intrusion detection nodes. The current invention solves the internal evil attacks and avoid the inability to reach consensus between nodes due to internal evil, thereby affecting the intrusion detection performance; at the same time, the intrusion detection model can resist external network attacks.

Technologies are generally described for systems and methods effective to provide migration of data to a cloud computing service without interruption of service to client devices. In an example, a method includes establishing a first communication link with one or more communication devices and establishing a second communication link with a source device. The method also includes transferring via the second communication link at least a data set of a plurality of data sets of the source device and storing at least the data set to a data store. Further, the method includes receiving, via the first communication link, a request for the data set or another data set of the plurality of data sets, wherein the request is received from a communication device of the one or more communication devices.

Two-level cloud system migration

Technologies are generally described for server resource allocation for distributed games. In one example, a method includes allocating a first set of resources for a first player instance on a first server, a second set of resources for a second player instance on the first server, and a third set of resources for a third player instance on a second server. The method also includes comparing a first relationship strength defined between the first player instance and the second player instance with a second relationship strength defined between the first player instance and the third player instance. Further, the method includes distributing at least one of the first set of resources, the second set of resources, or the third set of resources between the first server and the second server based on a result of the comparing.

Resource management for distributed games

When a picture displayed on a client device is enlarged, the client device may be configured to insert new pixels between two adjacent pixels in the picture. When actual values of the new pixels are stored on a server, the client device may submit a request to the server for actual values of the new pixels. Responsive to the request, the server may first calculate interpolation values in accordance with the same interpolation algorithm and then calculate a difference value based on the interpolation values and the actual values stored on the server. If the calculated difference value is greater than a threshold value, the server may transmit the actual values for the new pixels to the client device. Otherwise, the server may instruct the client device to calculate the interpolation values.

A method of forming a film layer and a substrate comprising the film layer to reduce occurrence of defects and improve the quality of the film layer are described. The method of forming a film layer comprises forming a plurality of sub-film layers of a same material overlapped with each other on a substrate by multiple steps to constitute the film layer, wherein each time a sub-film layer is formed, the newly-formed sub-film layer is cleaned immediately. The substrate comprises a film layer formed by the above method.
