A method for processing a request for anonymisation of a source IP address of an IP packet is described, the IP packet being transmitted by a transmitting device to a recipient device via a communications network, the transmitting device being connected to the network via a network terminal apparatus. The method is carried out by an anonymisation device positioned for cutting the flow between the network terminal apparatus and the recipient device, and comprises receiving the packet; establishing whether the source IP address has to be anonymised or not; if a result of the verification is negative, routing the packet to the recipient device; if the result of the verification is positive and if the anonymisation device has an address translation function: replacing the source IP address with an IP address of the anonymisation device; and. If the result of the verification is positive and if the anonymisation device does not have an address translation function, a step of routing the IP packet is routed to the recipient device via an apparatus of the network which has an address translation function.

A communication method and apparatus are provided. In the method, an SMF sends first information to a first user plane network element, where the first information indicates the first user plane network element to send a report message to the SMF when receiving a first DNS response message that meets a first condition, and the report message includes information about an application server indicated by the first DNS response message or information about a data network corresponding to the application server. The first user plane network element sends the report message to the SMF when determining that the received first DNS response message meets the first condition. The SMF inserts the local session anchor based on the report message.

Examples include a computing system having a plurality of processing cores and a memory coupled to the plurality of processing cores. The memory has instructions stored thereon that, in response to execution by a selected one of the plurality of processing cores, cause the following actions. The selected processing core to receive a packet and get an original tuple from the packet. When no state information for a packet flow of the packet exists in a state table, select a new network address as a new source address for the packet, get a reverse tuple for a reverse direction, select a port for the packet from an entry in a mapping table based on a hash procedure using the reverse tuple, and save the new network address and selected port. Translate the packet's network address and port and transmit the packet.

A message encapsulation method and apparatus, and a message decapsulation method and apparatus are provided. The message encapsulation method includes encapsulating a first message according to a preset encapsulation format to obtain a second message, where the first message is obtained by encapsulating a traffic stream, the second message carries stream attribute information, and the stream attribute information is used for indicating a feature attribute of the traffic stream.

An example method includes receiving a domain name server (DNS) query initiated by an endpoint device, determining a current port assignment for the endpoint device, changing an allocation of ports for the endpoint device from the current port assignment based on a predicted port allocation need for a current communication session associated with the domain name server query, and performing a network address translation in accordance with the allocation of ports for the endpoint device.

A method performed by a computing system includes receiving a first request from a first pod being executed on the computing system, responding to the first request with an Internet Protocol (IP) address and a first port range, receiving a second request from a second pod being executed on the computing system, and responding to the second request with the Internet Protocol (IP) address and a second port range that is different than the first port range. The method further includes, with a networking service implemented within the kernel, processing network traffic between external entities and the first and second pods by updating source and destination IP addresses and ports of packets of the network traffic.

Systems and methods are disclosed for client-based control of revising caller identifications (IDs) for communications between a private network and a public network. An apparatus including a communications provider server and processing circuit that communicates client-specific sets of data over an interface protocol. The telecommunications-providing server revises a caller ID for a call based on the client-specific sets of data, an identifier that corresponds to a requesting endpoint, and a geographic region determined from the call request. Further, the telecommunications-providing server connects the VoIP call by accessing and passing a provisioned number. The provisioned number includes the revised caller ID which is a local number identified by the determined geographic region that the endpoint is located.

In general, this disclosure describes a cloud exchange (or “cloud exchange”) that offers a cloud-to-cloud interface (CCI) for interconnecting cloud services to tenants within public clouds. As described herein, the cloud exchange may be configured with a cloud-to-cloud interface that enables tenant applications of a public cloud to subscribe to and communicate with cloud services, using an end-to-end layer 3 path, in some cases without requiring a separate routing protocol session with a public edge device for the public cloud. In some examples, the public cloud provides a virtual layer 2 connection from a tenant within a public cloud to a routing instance of the cloud exchange, and the cloud exchange uses the routing instance to route service traffic between the tenant and the cloud services.
