A method, a device, and a system for network address translation traversal are provided. The method is performed by a system in which a first terminal communicates with a second terminal. The first terminal is in a network constructed by a first NAT device, the second terminal is in a network constructed by a second NAT device, and the first NAT device is different from the second NAT device. The method implements NAT traversal through bidirectional dynamic detection of TTL values at both ends of the NAT traversal, to resolve a problem of low NAT traversal efficiency.

A computer-implemented method, operable on a device in a content delivery network (CDN), wherein the CDN delivers content on behalf of at least one content provider, the device implementing a content delivery (CD) service, the method includes receiving a request from a client for particular content; determining a second device in the CDN, the first device being in a first cluster and the second device being in a second cluster distinct from the first cluster; migrating the request to the second device; and then providing the second device with network traffic from the client.

Communications methods and apparatus for preserving STIR/SHAKEN original attestation/signature information for diverted Session Initiation Protocol (SIP) messages and/or calls. An exemplary method embodiment includes the steps of: receiving, at a first Session Border Controller (SBC), a diverted Session Initiation Protocol (SIP) INVITE message corresponding to a first call, the diverted SIP INVITE message not including an Identity header; obtaining an original Identity header or information from the original Identity header corresponding to the first call using one or more of the following: information included in the diverted SIP INVITE message, information included in a Session Description Protocol message included in the diverted SIP INVITE message, an SBC trunk group, or a source Internet Protocol (IP) address transport protocol port of an IP packet carrying the diverted SIP Invite message; and generating an Identity header based on the original Identity header or information from the original identity header.

Techniques are described for vetting unwanted calls. At an inbound customer call handling apparatus, a SIP INVITE is received from a destination carrier servicing the inbound customer intended for a destination user agent (UA) device of the inbound customer. The SIP INVITE includes a current origination identifier (ORIG ID) comprised of a fixed length character string. The call handling apparatus accesses a database of stored ORIG ID character strings, each stored ORIG ID character string in the database having been included with a previous SIP INVITE that has been previously associated with an unwanted inbound call. The call handling apparatus analyzes the current ORIG ID character string to determine if it matches any stored ORIG ID character strings in the database. When there is a match to a stored ORIG ID character string, the SIP INVITE is not forwarded to the destination UA device. Otherwise, it is forwarded to the destination UA device.

A method and apparatus for communications in internet-of-things devices are provided. An exemplary apparatus includes an IoT server device. The IoT server device includes a communications device and a resource name map including a full identifier string and a short identifier string. A discovery responder provides the full identifier string and a short identifier string to a client device through the communications device.
