A first edge server of multiple edge servers of a distributed edge computing network receives a request from a client device regarding a resource hosted at an origin server according to an anycast implementation. The first edge server modifies the request to include identifying information for the first edge server prior to sending the request to the origin server. The origin server responds with a response packet that includes the identifying information of the first edge server. Instead of routing the response packet to the client device directly, one of the multiple edge servers receives the response packet due to the edge servers each having the same anycast address. If the edge server that receives the response packet is not the first edge server, that edge server transmits the response packet to the first edge server, who processes the response packet and transmits the response packet to the client device.

A device estimating apparatus acquires one or more DNS queries transmitted from each device connected to a network and generates comparison source data in which each content of the acquired DNS queries is associated with one or more pieces of attribute information of each of the one or more devices that have transmitted the DNS queries having the content. Thereafter, when one or more DNS queries are acquired from an estimation target device, the device estimating apparatus reads, for each DNS query, attribute information of one or more devices associated with a content of the DNS query from the comparison source data and estimates an attribute of the estimation target device using the read attribute information.

A first network device associated with a network may establish an Internet protocol version 6 Multiprotocol BGP session with a second network device associated with the network. The first network device and second network device are both capable of forwarding both IPv4 and IPv6 packets with only an IPv6 address configured on the interface of both the first network device and second network device. The first network device may exchange Multiprotocol Reachability capability with second network device for corresponding 2-tuple Address Family Identifier/Subsequent Address Family Identifier. The first network device may advertise Internet protocol version 4 network layer reachability information and may advertise Internet protocol version 6 network layer reachability information with IPv6 extended next hop encoding using Internet Assigned Numbering Authority assigned capability code value 5 to second network device.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and apparatus of a wireless network are disclosed. The method includes transmitting a first request message to request allocation of a multimedia broadcast multicast service (MBMS) group identifier from a service capability server/application server (SCS/AS) to a service capability exposure function (SCEF), the first request message including an external group identifier and an SCS/AS identifier, and receiving a first response message including the MBMS group identifier from the SCEF to the SCS/AS.

A content distribution network includes a first server in communication with an anycast server that provides content via a unicast signal, and with a multicast server that provides the content via a multicast signal. The first server is configured to receive a list of source addresses associated with the content, and to provide a metadata file including an anycast Internet protocol address of the anycast server from the list of source addresses as an Internet protocol address of the content in response to a first request for the content. When the number of client devices requesting the content exceeds a first threshold, the first server receives an updated list of sources including a multicast Internet protocol address of a multicast server, and provides the multicast Internet protocol address of the multicast server as the Internet protocol address of the content in the metadata file.
