Abstract: A method for blockchain-based data traffic calculation includes: when data traffic generated between a first node and a second node in a CDN system is detected, recording the data traffic generated by the first node or the second node by triggering a transfer between a first account corresponding to the first node and a second account corresponding to the second node; acquiring account information of the first account and/or the second account, where the account information includes at least an account balance and/or a transfer record; and calculating traffic information of the first node and/or the second node based on the account information of the first account and/or the second account.

Abstract: The present disclosure provides a data transmission method and system. The method includes: requesting to access a data file from an intermediate node; receiving response data packets of the data file from the intermediate node, where the response data packets include a data file signature code uniquely identifying the data file; looking up the signature code in a signature code database; when the signature code is present in the signature code database, notifying the intermediate node to stop the transmission of the data file, and creating a cache pointer record to point to a cached data file corresponding to the signature code; and sending the cached data file to a user agent.

Abstract: An Internet anti-attack method includes: an authentication server receives a service access request, sent by a user, from a content delivery network node group through a WEB interface, where the service access request includes an IP address of the user. The authentication server sends an access authentication request to a security gateway, where the access authentication request includes the IP address of the user, and the access authentication request is used to instruct the security gateway to allow a service-serving request that includes the IP address of the user to be sent to the service server.

Abstract: A system, a method, and a device for network load balance processing are provided. The network load balance processing method includes: establishing, by a virtual server, connection with a client; sending, by the virtual server, a control command to a back-end server and information related to connection to the back-end server, such that the back-end server starts a connection service based on the control command directed to connection; forwarding, by the virtual server, a data request packet from the client, where the back-end server is configured to respond to the data request packet based on the connection service and send response information to the client. Through the present disclosure, the issue of high memory consumption in the network load balance processing is solved, thereby achieving an effect of low memory consumption in the network load balance processing.
