The embodiment of the present disclosure provides a back-to-source relationship management system, method, apparatus, server and storage medium. The back-to-source relationship management system comprises a back-to-source relationship management server, which is configured for obtaining a target domain name corresponding to a target CDN node back-to-source relationship to be adjusted and adjustment information; using the adjustment information to adjust the target CDN node back-to-source relationship to obtain the adjusted target CDN node back-to-source relationship; synchronizing the target domain name and the adjusted target CDN node back-to-source relationship to a cache management server; the cache management server is configured for receiving the target domain name and the adjusted target CDN node back-to-source relationship; using the adjusted target CDN node back-to-source relationship to update the CDN node back-to-source relationship corresponding to the target domain name and obtain a new CDN node back-to-source relationship.

A domain name access method and a device are described. As described herein, a domain name server (DNS) server performs resolution on a domain name requested by the terminal device. The DNS server may then send an internet protocol (IP) address of an application server obtained through the resolution and use condition information to the terminal device. With this, communication efficiency of the terminal device can be improved, and waste of transmission resources in a communications system is also avoided.

Network identifiers are extracted from route advertisements. A table associates virtual network identifiers with provider edge devices. When a virtual network identifier extracted from a route advertisement matches a virtual network identifier in the table, the route advertisement is propagated to the provider edge devices associated with that virtual network identifier in the table. The route advertisement is not propagated to provider edge devices not associated with that virtual network identifier in the table.

Embodiments of this application relate to the field of communication technologies, and provide a routing information publishing method. The method includes: An edge transport device connected to a first edge device in a first network domain receives, based on a control plane protocol message, first routing information that is from a controller and that includes an address of a second edge device in a second network domain and a destination address of the second network domain, and sends the first routing information to the first edge device, so that the first edge device generates, based on the first routing information, a forwarding table that is of the first edge device and that is used to indicate a forwarding relationship between the first network domain and the second network domain.

A wireless client device communicates, to an access point over a secure channel, a mapping of a dynamic device address to a stable device address. By communicating the mapping, the access point is able to determine that packets received from two different device addresses originate from a common device. The access point is then able to maintain an association between the originating device and other network resources assigned or allocated to the originating device, such as IP addresses or infrastructure station address, which is used to identify the originating device to other devices outside the network in some embodiments.

Systems, methods, and apparatus to identify media devices are disclosed. An example apparatus includes a listing retriever to retrieve a list of device names corresponding to devices identified as present on a local area network, the list of device names retrieved from a network activity measurement system located outside of the local area network. The example apparatus includes a communications analyzer to identify a list of hardware addresses of devices on the local area network. The example apparatus includes a mapper to receive a mapping between a device in the list of devices and a hardware address in the hardware addresses. The mapper is to transmit the mapping to the network activity measurement system.

In some embodiments, a method stores domain name system (DNS) resolution mappings from a domain name to an address in a first table. The DNS resolution mappings are intercepted from DNS responses being sent by a DNS server. The first table is sent to a manager for validation of the DNS resolution mappings. Then, a second table is received from the manager that contains validated DNS resolution mappings. The method intercepts a DNS response that includes a domain name to address resolution mapping from the DNS server and validates the domain name to address resolution mapping using a validated DNS resolution mapping in the second table.
