A verification method used for network application access , wherein the method comprises:receiving, by a control device, a first encrypted token sent by a verification server, wherein the first encrypted token comprises first location information and an access permission of a user, and the first location information is used to identify a network location at which a terminal is located when sending a user verification request, and the access permission of the user comprises a list of content that can be accessed by the user;generating, by the control device, a second encrypted token according to the first encrypted token, wherein the second encrypted token comprises the first location information;sending, by the control device, the second encrypted token to the terminal;receiving, by the control device, the second encrypted token sent by a forwarding device;performing, by the control device, verification of the second encrypted token based on the first encrypted token; andsending, by the control device, a first message to the forwarding device after the verification of ...

Method, device and system for managing network service

This application provides a network service management method, apparatus, and system. A controller receives an access request message that is of a to-be-served flow and that is sent by a network device, where the access request message includes an identifier of the to-be-served flow and an identifier of a terminal that sends the to-be-served flow. The controller determines service level information of the to-be-served flow based on the identifier of the terminal and the identifier of the to-be-served flow. The controller determines a transmission path of the to-be-served flow and a transmission path of a being-served flow based on the service level information of the to-be-served flow and service level information of the being-served flow. The controller publishes the transmission path of the to-be-served flow and the transmission path of the being-served flow to the network device. In the embodiments of this application, the controller simultaneously determines paths of the to-be-served flow and the being-served flow based on content of a plurality of aspects, and dynamically adjusts the to-be-served flow and the being-served flow based on a flow type, so that more SD-WAN users meet an optimal solution of a service level agreement signed between the SD-WAN users and an SD-WAN service provider.

Verification method, apparatus, and system used for network application access

This application provides a verification method, apparatus, and system that are used for network application access, and the method includes: performing, by a verification server, user identity verification on a terminal, where the user verification request includes first location information; generating, by the verification server, an encrypted token according to the first location information in the user verification request after determining that the terminal succeeds in the user identity verification; and sending, by the verification server, the encrypted token to a control device. In the verification method used for network application access in embodiments of the present invention, application-layer verification needs to be performed, and in addition, it needs to be determined, by using network location information of a terminal, whether the terminal that performs content access is valid. In a terminal verification manner of the embodiments of the present invention, it may be determined whether a terminal that performs content access is a terminal used by a user on which user verification is performed. Therefore, this can effectively avoid an application-layer-based network attack such as an MITM attack, and further effectively improve security of the network application access.

Energy-saving quick-freezing method for Trachinotus ovatus

A quick-freezing method for Trachinotus ovatus. The method comprises the following steps: putting Trachinotus ovatus into a liquid nitrogen flash freezer, the cavity temperature of which is A, and when the center temperature of the fish body reaches -6 to -4°C, turning off the liquid nitrogen flash freezer; when the cavity temperature of the liquid nitrogen flash freezer rises to B, starting the liquid nitrogen flash freezer, and when the center temperature of the fish body reaches -19 to -17°C, turning off the liquid nitrogen flash freezer; and finally, taking out the Trachinotus ovatus, and storing same at -19 to -17°C, wherein A ranges from -105°C to -85°C, B ranges from -95°C to -65°C, and A < B. By means of the quick-freezing method for Trachinotus ovatus, the consumption of liquid nitrogen is reduced, thereby saving energy; and the hardness loss and cooking loss of muscle of Trachinotus ovatus are also reduced, thereby effectively guaranteeing the quality of the Trachinotus ovatus, and prolonging the shelf life of the Trachinotus ovatus.
