A data processing method based on a mobile edge computing (MEC) platform includes receiving a target data packet transmitted by a terminal, determining whether the target data packet includes a network service header (NSH) tag, and when determining that the target data packet includes the NSH tag, transmitting the target data packet to a target MEC platform corresponding to the NSH tag for data processing.

A DNS resolution request for a hostname of a CDN is received. An edge server of the CDN may be identified, which may be associated with a subnet. The subnet is used to generate a response IP address, where the remaining bits of the response IP address may be used to store requestor information (e.g., a requestor IP address). When a client computing device uses the response IP address to access the edge server, requestor information is extracted and associated with client computing device information (e.g., an IP address and/or location, etc.) in an association record. Association records may be used to determine predicted characteristics for devices served by a requestor. When the authoritative DNS server resolves a request from the requestor, such predicted characteristics may be used rather than relying solely on information about a requestor. Thus, an edge server proximate to the predicted location may be returned instead.

Systems, methods and products for identifying IP mass hosts and determining whether they are good or bad. One embodiment is a method including selecting a first candidate IP address, identifying a set of domains hosted at the IP address, and identifying registrants of the domains. A number of unique ones of the registrants is determined and if the number of unique registrants exceeds a threshold number, the candidate IP address is deemed an IP mass host. Otherwise, the candidate IP address is deemed not to be an IP mass host. For an IP mass host, domains that have bad reputations are identified, and it is determined whether the bad domains comprise at least a threshold percentage of the total hosted domains. If the IP mass host has at least the threshold percentage of bad domains, the IP mass host is deemed a bad mass host.

To serve content through a content delivery network (CDN), the CDN must have some information about the identity, characteristics and state of its target objects. Such additional information is provided in the form of object metadata, which according to the invention can be located in the request string itself, in the response headers from the origin server, in a metadata configuration file distributed to CDN servers, or in a per-customer metadata configuration file. CDN content servers execute a request identification and parsing process to locate object metadata and to handle the request in accordance therewith. Where different types of metadata exist for a particular object, metadata in a configuration file is overridden by metadata in a response header or request string, with metadata in the request string taking precedence.

A method for loading website security information, and a browser apparatus. The method comprises: receiving a website address entered by a user via an address bar of a browser; performing security authentication of a digital certificate according to an authentication type of a network server corresponding to the website address, wherein the digital certificate is issued by a certificate authority (CA); and loading a security authentication identifier corresponding to the security authentication into the address bar of the browser after the security authentication has been passed. Authentication displaying is performed in the browser on the basis of the authentication of the digital certificate, and the security of a website is directly displayed.
