Abstract: The present application discloses a method for caching data. The method includes: a controller calculates a local caching gain of first content for each forwarding device on the first content delivery path, wherein a local caching gain of the first content of an ith forwarding device is generated by calculation according to a first parameter and a popularity of the first content, and the first parameter is used for identifying bandwidth consumed by transmitting the first content between the ith forwarding device and the server. The controller obtains a first caching gain, wherein the first caching gain is a maximum value of local caching gains of all forwarding devices on the first content delivery path. The controller sends the first caching gain to the server and sends the local caching gain of the first content to the ith forwarding device.

Abstract: The present disclosure provide a method for determining a content acquisition path, a method for processing a content request and a corresponding apparatus and system. The method for determining the content acquisition path includes: receiving a request from a user, where the request is used for requesting an original content provider to provide a content, and the request carries a name of the content, a network address of the original content provider and a network address of the user; calculating at least two forwarding paths to the original content provider, and determining a content acquisition path according to link cost on each forwarding path and a cache hit rate of a network node on each forwarding path to the content; and sending the request to a next network node according to the content acquisition path, for enabling the next network node to forward or respond to the request.

Abstract: The present disclosure discloses a method for acquiring a content, a user equipment and a cache node. The method includes: a user equipment requests a target content from a management node; receives a first probe packet and a second probe packet, the first probe packet includes an identifier of a fragment of the target content and a shortest distance from the fragment to the user equipment on a first path, and the second probe packet includes the identifier of the fragment of the target content and a shortest distance from the fragment to the user equipment on a second path; determines an optimal path according to the shortest distance from the fragment to the user equipment on the first path and the shortest distance from the fragment to the user equipment on the second path; and sends a second acquiring request used for acquiring the fragment through the optimal path.

Abstract: 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. 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.

Abstract: A packet parsing method includes a source device receives a first ciphertext from a control device, where the first ciphertext is used to verify reliability of a packet from a parsing device, and the parsing device is a trusted device selected on a path between the source device and a destination device. The source device obtains a second packet including the first ciphertext according to the first ciphertext and a first packet, and sends the second packet to the destination device. The parsing device obtains, according to the second packet and a device identifier of the parsing device, a third packet including verification information and the first ciphertext. The destination device receives the third packet from the parsing device, and verify reliability of the third packet using the verification information and the first ciphertext included in the third packet.
