Apparatuses, methods, and systems are disclosed for ePDG selection. One apparatus 200 includes a processor 605 that identifies a region in which the apparatus 200 is currently located, transmits a query 800 to a domain name system (“DNS”) server 270 based on the region not being a home region 210 of the apparatus 200, the query 800 identifying the region in which the apparatus is currently located, and selects an enhanced packet data gateway (“ePDG”) 140 based on a response to the query. The apparatus also includes a transceiver 630 that communicates with a mobile communication network 130 over a wireless local area network (“WLAN”) 235.

Disclosed herein are system, method, and computer program product embodiments for routing communication to applications. In an embodiment, first application can transmit a connection to a second application without knowing the exact route address of the second application. An agent can intercept the connection from a first application intended for a second application. The agent can identify the route address for the second application, determine the protocol the connection was intended to be transmitted, and forward the connection based on the route address and protocol to the second application.

A method for selecting a gateway node for a terminal which connects to its registered domain via an access domain and, in a predetermined scenario, an intermediate domain, the access domain having an associated domain name system arranged to return an address of a gateway node based on a domain name system query. The method includes using a first part of such a query to identify the registered domain of the terminal to the domain name system and a second part of the query to indicate to the domain name system that it should use a predetermined mapping to return the address of a gateway node based on the query, the predetermined mapping being one which returns an address of a gateway node either in the registered domain or in an intermediate domain based on the registered domain identified in the query and on the access domain.

The present invention provides a method for obtaining a serving gateway, a mobility management node, a data gateway, and a system. A method for obtaining a serving gateway according to an embodiment of the present invention includes: when a UE is switched from an old-side mobility management node to a new-side mobility management node, sending, by the new-side mobility management node, a domain name resolution request to a domain name system DNS server according to access information of the UE; receiving a hostname of a device returned, according to the domain name resolution request, by the DNS server; obtaining a hostname of a new-side available S-GW; and selecting the new-side available S-GW closest to the device on geographic topology as a new-side S-GW. User service data transmission time delay can be reduced through the method.

A method for processing a cloud service in a cloud system, wherein the cloud system includes a hosted cloud, an allied cloud, and an alliance management apparatus, wherein the hosted cloud includes a first region, the allied cloud includes a second region, the hosted cloud further provides a virtual region for a user, and the virtual region is mapped by the second region on the hosted cloud. The alliance management apparatus enables a user of the hosted cloud to obtain unified experience when the user accesses the first region and the virtual region in the cloud system, for example, unified experience in control interface access, and unified experience in application programming interface (API) access.

In one embodiment, a method includes determining, by a router, a common prefix pool from a transport interface associated with a transport virtual private network (VPN). The method also includes identifying, by the router, a prefix associated with a service VPN and generating, by the router, an IPv6-to-IPv6 Network Address Translation (NAT66) prefix translation using the common prefix pool and the prefix. The NAT66 prefix translation includes a predetermined prefix length. The method further includes automatically installing, by the router, the NAT66 prefix translation into a translation table.

Embodiments of a device and method are disclosed. In an embodiment, a method of network device name management involves at a cloud server, determining a device name of a network device to be deployed at a customer site based on site survey result information of the customer site, at the cloud server, receiving network device information of the network device after the network device is deployed at the customer site, and at the cloud server, associating the device name of the network device with the network device information of the network device.

Systems, methods and devices are provided for registering DNS hostnames of Internet host devices for very large domain zones (VLZ) stored on a DNS server on a network, including setting a pseudo-zone as the VLZ, intercepting DNS updates to the pseudo-zone, mapping the entries in the pseudo-zone into a hierarchy of real parent zones and sub-zones using a mapping formula, and translating DNS updates to the pseudo-zone from an original fully qualified domain name (FQDN) into a at least one new FQDNs and adding the at least one new FQDNs to an authoritative DNS Server.

Disclosed is an effective domain name defense solution in which a domain name string may be provided to or obtained by a computer embodying a visual domain analyzer. The domain name string may be rendered or otherwise converted to an image. An optical character recognition function may be applied to the image to read out a text string which can then be compared with a protected domain name to determine whether the text string generated by the optical character recognition function from the image converted from the domain name string is similar to or matches the protected domain name. This visual domain analysis can be dynamically applied in an online process or proactively applied in an offline process to hundreds of millions of domain names.

The system and methods described herein can classify electronic activities based on sender and recipient information. The system can determine a relationship between a sender of an electronic activity and at least one recipient of the electronic activity using a sender node profile and a recipient node profile. The system can assign a tag to the electronic activity based on the relationship between the sender and one or more recipients of the electronic activity. The system can process the electronic activity based on the assigned tag.
