  • Patent number: 10027693
    Abstract: A method, a device, and a system for alerting against unknown malicious codes includes judging whether any suspicious code exists in the packet, recording a source path of the suspicious code and sending alert information that carries the source path to a monitoring device. The embodiments of the present disclosure report the source paths of suspicious codes proactively at the earliest possible time, which lays a foundation for shortening the time required for overcoming virus threats, and avoids the trouble of installing software on the terminal.

  • Patent number: 9882975
    Abstract: A method and an apparatus for buffering and obtaining resources as well as a resource buffering system are disclosed. The method includes: obtaining an access popularity value of a resource from a database at intervals of a first preset time, and obtaining load values of cache servers from the database if determining that the access popularity value reaches a preset first threshold; and determining a duplication cache server for duplicating the resource according to the access popularity value and the load values, and notifying the duplication cache server to duplicate the resource from a cache server that stores the resource and buffer the resource. The method overcome the problems in the prior art, namely, the same resource is buffered in only one cache server and the relatively idle cache servers are unable to share loads with busy cache servers. The method improves extensibility and working efficiency of the buffering system.

  • Patent number: 9117033
    Abstract: A method, device, and system for packet transmission on the PCIE bus according to the embodiments of the present invention, a SCSI protocol packet is encapsulated to obtain an encapsulated SCSI protocol packet, and the encapsulated SCSI protocol packet is carried in a PCIE data packet, and then the PCIE data packet carrying the encapsulated SCSI protocol packet is transmitted to the receiver device through the PCIE bus. Thereby, transmission of SCSI protocol packets is implemented on the PCIE bus, and any devices interconnected through the PCIE bus can operate each other through SCSI protocol packets with a high data transmission bandwidth and high processing speed, without requiring a specific physical device or adapter to perform protocol conversion.

  • Patent number: 9088607
    Abstract: The present invention discloses a method for network attack protection, a device, and a system thereof. The method includes: receiving information about attack source, in which the information about the attack source carries address information about an attacker; obtaining address information about a gateway corresponding to the attacker according to the address information about the attacker and a preset mapping relationship between the attacker and the gateway corresponding to the attacker; and sending a first control message to the gateway corresponding to the attacker according to the address information about the gateway corresponding to the attacker, wherein the first control message instructs the gateway corresponding to the attacker to control traffic of the attacker. The present invention may be used on a communications network to prevent the attacker from attacking victim hosts on the network from the root, avoid blockage on the upstream network of the victim hosts.

  • Patent number: 8987936
    Abstract: An apparatus and a method for peak shifting adjustment are disclosed. The apparatus includes a controlling unit that is configured to sequentially control different outputting units to output the Pulse-Width Modulation (PWM) signals according to a preset time sequence. The interval between two adjacent outputted PWM signals is T1, which is the time when the current required by an electric device is higher than the normal current in case of an increase of the duty cycle of the PWM signals. At least two outputting units are connected to corresponding electric devices and configured to output the PWM signals to the corresponding electric devices according to the control of the controlling unit.
