Methods and apparatus are disclosed for configuring one or more processors to implement service function chains comprising one or more virtualised service functions. A method according to one aspect, performed by a processing module (330) implemented on one or more processors (30), involves steps being performed in respect of at least one new virtualised service function (33) to be included in a service function chain of: determining a position in the service function chain at which the new virtualised service function (33) is to be included; allocating at least one internal address to the new virtualised service function, the at least one internal address being an address to be usable by a switching processor (34); and providing to the switching processor (34) an indication of the at least one internal address allocated to the new virtualised service function (33).

Methods, systems, and devices for wireless communications are described. A first node of an integrated access and backhaul (IAB) network may identify a second, neighboring non-parent node of the TAB network. The second node may be associated with a timing source which may provide more accurate timing information than the parent node of the first node. The first node may transmit a first random access message to the second node to initiate a random access procedure. The second node may transmit a second random access message to the first node, the second random access message including timing information based on the timing source. The first and second nodes may terminate the random access procedure based at least in part on receiving the second random access message.

Systems, methods and devices for location-based services are disclosed in the present invention. A multiplicity of network devices, a database, and a server platform in network-based communication. The database stores a space-network model binding IP addresses and physical locations. The server platform is operable to generate at least one geofence in the space-network model and specify entitlements for the location-based services within the at least one geofence. The at least one geofence and specific entitlement are stored to the database. The multiplicity of network devices is configured to learn the space-network model and the at least one geofence and perform tasks based on the entitlements specified for the location-based services within the at least one geofence.

The present disclosure provides a method for communication between a network device and a terminal device, where the network device stores a correspondence between a link-layer address and an IP address that are of the terminal device, and the method includes: obtaining, by the network device, a first link-layer address; determining whether a quantity of IP addresses corresponding to the first link-layer address reaches a threshold; if the quantity reaches the threshold, selecting an IP address from the IP addresses, where a quantity of selected IP addresses is not greater than the maximum quantity; saving a correspondence between the first link-layer address and the selected IP address; and sending, according to the selected IP address, a message to a terminal device having the first link-layer address, where the message is used to notify the terminal device whether an IP address is selected by the network device.

A method for securing network communication between containers by a terminal, includes: a step of installing an HSI (Hyperion Secure Interface) for communication with a secure bridge included in an NIC (Network Interface Chip) in a secure container through a manager module; a step of changing a source address of a transmission packet to a specific token on the basis of a map of the HSI through the manager module; a step of delivering the transmission packet to the secure bridge through the HSI; a step of determining whether the specific token of the transmission packet is valid; and a step of changing the specific token to the source address and delivering the transmission packet to a target container when the specific token is valid.

Embodiments of the present application describe techniques of facilitating directing operations. The techniques comprise obtaining guest information of a target studio, where the guest information includes a room identification number of a guest room, the guest room associated with producing content scenes; generating a directing configuration file based on the guest information of the target studio; and sending the directing configuration file to a director terminal associated with content directing, so that the director terminal performs a directing operation based on the directing configuration file.

Methods, systems, and computer readable media for hiding network function (NF) instance identifiers (IDs) in communications networks are disclosed. One method for hiding NF instance IDs in a communications network occurs at an NF repository function (NRF) comprising at least one processor. The method comprises: receiving, from a first NF, an NF registration request message for registering a first NF instance of the first NF, wherein the NF registration request message includes a first NF instance ID for identifying the first NF instance; storing, in a data store, a mapping between the first NF instance ID and at least one pseudo NF instance ID, wherein the data store includes mappings between NF instance IDs and related pseudo NF instance IDs; and generating and sending, to the first NF, an NF registration response message including the at least one pseudo NF instance ID for identifying the first NF instance.

A method includes, in a computing system that runs clients on multiple interconnected compute nodes, running on the compute nodes respective virtual switches and respective virtual heads. Each client is provisioned to direct file access commands using one or more access protocols to a respective virtual head running on the compute node on which the client runs, via a respective virtual switch running on the compute node on which the client runs. The file access commands issued by the clients are executed by communicating among the virtual heads using an inter-node communication protocol that is independent of the access protocols used by the clients.
