A content delivery method, and related apparatus, that involves the operations of receiving a request for a content resource including at least one embedded resource with a tag. Upon identification of the tag, using at least one delivery parameter to generate a modified embedded resource. Embedding the modified embedded resource in a content resource, such as as an HTML document. Delivering, such as in response to request from a browser, the content resource with the modified embedded resource.

Content Delivery Network (CDN) detection processing and scheduling methods, corresponding devices and nodes thereof are disclosed. The detection processing device issues one or more IP addresses in a first IP segment to a plurality of CDN nodes, receives link detection results reported by the plurality of CDN nodes, the link detection results comprising the information of time delay for accessing the IP addresses by the CDN nodes, and selects, from the plurality of CDN nodes, a priority scheduling node of the first IP segment according to the time delay information. The scheduling node searches for the priority scheduling node of the first IP segment according to the information of the first IP segment, and provides the information of the identified priority scheduling node to the user terminal.

The present disclosure provides a domain name resolution method, apparatus, device, and medium based on a content delivery network. The domain name resolution method, applicable to an authoritative domain name system, comprises: receiving a domain name to be resolved transmitted by a local domain name system; determining a target hosted zone based on a domain name suffix of the domain name to be resolved, wherein a plurality of first sub-domain names are recorded in the target hosted zone; matching the domain name to be resolved with the plurality of first sub-domain names, and determining a first sub-domain name that matches the domain name to be resolved; determining a resolution result of the domain name to be resolved based on the first sub-domain name that matches the domain name to be resolved, and feeding back the resolution result to the local domain name system, wherein the local domain name system is configured to transmit the resolution result to a client.

A method of operation of a cellular communications system is disclosed. The method comprises: at a MME: receiving an attach request from a UE; sending a location update request to a HSS; receiving a location update acknowledgement; sending, to a DNS, a DNS query request comprising an APN FQDN; receiving a DNS query response comprising information that indicates candidate PGWs that satisfy the DNS query request and at least two PGWs belonging to a same PGW set; selecting the first PGW; sending, to a SGW, a first create session request that comprises information that indicates the first PGW; receiving a first create session response; sending an attach accept to the UE; and at the SGW: receiving the first create session request from the MME; forwarding the first create session request to the first PGW; receiving the first create session response; and forwarding the first create session response to the MME.

Embodiments described herein relate to systems and methods for local name resolution in network communications. Particular embodiments may enable a device resolution request to include a name that identifies the user device issuing the resolution request. A proxy server may accept the resolution request, and respond with a service internet protocol address that is customized to that user device, such that compatible user devices on the same local area network will each receive a different service IP address. When the proxy server receives traffic on a particular service IP address from a local area network, the proxy server may identify the compatible device even if a network address translation device has adjusted the requesting IP address for the device. Particular implementations may enable acceleration of HTTPS communications by the proxy server, or other such benefits.

Systems and methods provide an ability to split multiple email addresses having the same email domain across a plurality of email service providers. A first email server receives a forwarded email message from a second email server, the forwarded email message including an original domain and an intermediary domain, the intermediary domain added by the second email server. The first email server removes the intermediary domain from the recipient address and delivers the email message to a corresponding email account that is serviced by the first email server.

The present disclosure provides a domain name resolution method, apparatus, device, and medium based on a content delivery network. The domain name resolution method, applicable to an authoritative domain name system, comprises: receiving a domain name to be resolved transmitted by a local domain name system; determining a target hosted zone based on a domain name suffix of the domain name to be resolved, wherein a plurality of first sub-domain names are recorded in the target hosted zone; matching the domain name to be resolved with the plurality of first sub-domain names, and determining a first sub-domain name that matches the domain name to be resolved; determining a resolution result of the domain name to be resolved based on the first sub-domain name that matches the domain name to be resolved, and feeding back the resolution result to the local domain name system, wherein the local domain name system is configured to transmit the resolution result to a client.

A content provider has a plurality of content provider domain names, and a content delivery network (CDN) allocates a plurality of CDN domain names to the particular content provider. The content provider domain names are mapped to the CDN domain names. CDN domain names are bound to corresponding CDN clusters. The binding of the of CDN domain names to corresponding CDN clusters is modified.

A content delivery method, and related apparatus, that involves the operations of receiving a request for a content resource including at least one embedded resource with a tag. Upon identification of the tag, using at least one delivery parameter to generate a modified embedded resource. Embedding the modified embedded resource in a content resource, such as an HTML document. Delivering, such as in response to request from a browser, the content resource with the modified embedded resource.
