EXTENDING A LOCAL AREA NETWORK SECURELY
20230030301 · 2023-02-02 ·

A first router obtains a first network address of a first local area network (LAN) implemented by a second router and a first subnet mask associated with the first LAN. The first router causes the establishment of a secure communications channel with the second router. The first router determines that a computing device seeks to join the first LAN. The first router obtains an internet protocol (IP) address that has a same network address as the first network address and sends, to the computing device, the IP address and the first subnet mask for use by the computing device.

ETHERNET PDU SERVICE FOR 5G NETWORKS
20230033048 · 2023-02-02 ·

An Ethernet protocol data unit (PDU) over 5G service is provided. A network device in a core network stores addresses of advertised subnets, associated with multiple user equipment or customer premises equipment (UE/CPE) devices, in a subnet table that correlates a MAC address of each of the multiple UE/CPE devices to a subnet address. The network device receives an allocation and retention priority (ARP) request over a data link layer. The ARP request indicates an IP address for a target host of a data flow. The network device determines, based on the subnet table and the IP address, a MAC address of one UE/CPE device servicing the host address. The network device sends a directed ARP request to the UE/CPE device using the MAC address, receives in response a target MAC address for the target host, and sends a response to the ARP request with the target MAC address.

METHOD AND APPARATUS FOR TRANSMITTING ADDRESS INFORMATION, METHOD AND APPARATUS FOR OBTAINING ADDRESS INFORMATION, DEVICE, AND MEDIUM
20230086304 · 2023-03-23 ·

A method includes: receiving, by a session management function (SMF), a first identifier transmitted by user equipment (UE) in a protocol data unit (PDU) session establishment process (320); selecting a first edge application server discovery function (EASDF) for the UE according to the first identifier (340); and transmitting address information of the first EASDF to the UE (360).

Address generation for networks

A network includes at least two nodes that employ a routing protocol to communicate across a network. One of the nodes is a parent node and another of the nodes is a child node of the parent node. An address generator assigns a unique network address to the child node by appending an address value of a number of bits to a parent address of the parent node to create the unique network address for the child node.

Voice command integration for local network connected devices
11611796 · 2023-03-21 · ·

Various arrangements for facilitating smart television content receivers in a local network are provided. A primary television receiver executing a first operating system can receive audio data including human voice from a voice enabled remote control. The primary television receiver can transmit the audio data to a secondary television receiver executing a second operating system and that includes a voice command component. The secondary television receiver can convert the audio data into voice command data and transmit the voice command data to the primary television receiver. The primary television receiver can transmit the voice command data to a voice processing server via the Internet and receive, in response, a command generated based on the voice command data. The primary television receiver can transmit the command to the secondary television receiver. The voice command component can then control an operation of the secondary television receiver based on the command.

Network address allocation management using prefix allocation trees with asynchronous workflows

Disclosed are various embodiments for managing network address allocations using prefix allocation trees. In one embodiment, a request is received to allocate a particular network address block. The request specifies one or more attributes and at least one of a prefix or a size for the particular network address block. A prefix allocation tree is updated to indicate that the particular network address block corresponding to the prefix is allocated instead of free and to associate the attribute(s) with the particular network address block. An identification of an allocation of the network address block is returned in response to the request to allocate the particular network address block. An attribute index of the prefix allocation tree is updated asynchronously to index the attribute(s) in association with the particular network address block.

Multiple domain segment routing path computation

Aspects described herein include a method for use with a software-defined network controller, as well as an associated computer program product and system. The method comprises assigning a segment identifier to an endpoint node within a destination domain of a plurality of domains. Adjacent domains of the plurality of domains are connected via a respective set of two or more domain border routers. The method further comprises assigning a respective segment identifier to each domain. Each domain border router advertises the segment identifiers of the respective two adjacent domains. The method further comprises, responsive to a request from a headend node within a source domain of the plurality of domains, computing a path from the headend node to the endpoint node. The path includes (i) the segment identifiers of any domains between the headend node and the endpoint node, and (ii) the segment identifier of the endpoint node.

Wireless earphones with digital signal processors

Left and right earphones are independently wireless such that the left and right earphones are not physically connected when worn by a user. Each earphone comprises a speaker, microphone and a body portion with an SOC. Each SOC comprises a wireless communication circuit and a processor. Each processor comprises a digital signal processor for noise cancellation.

Identifying multiple nodes in a virtual network defined over a set of public clouds to connect to an external SAAS provider

Some embodiments establish for an entity a virtual network over several public clouds of several public cloud providers and/or in several regions. In some embodiments, the virtual network is an overlay network that spans across several public clouds to interconnect one or more private networks (e.g., networks within branches, divisions, departments of the entity or their associated datacenters), mobile users, and SaaS (Software as a Service) provider machines, and other web applications of the entity. The virtual network in some embodiments can be configured to optimize the routing of the entity's data messages to their destinations for best end-to-end performance, reliability and security, while trying to minimize the routing of this traffic through the Internet. Also, the virtual network in some embodiments can be configured to optimize the layer 4 processing of the data message flows passing through the network.

METHOD, APPARATUS AND SYSTEM FOR REALIZING CARRIER GRADE NETWORK ADDRESS TRANSLATION
20230130514 · 2023-04-27 ·

Provided are a method, an apparatus and a system for implementing carrier grade network address translation, an electronic device, and a computer-readable storage medium. The method includes: transmitting a first request to a control plane of a forwarding and control separated broadband access system, where the first request is used for applying to the control plane for a public network address range; receiving a first response returned by the control plane, where the first response includes allocated public network address range information; receiving a public network address allocated to a user by the control plane according to the public network address range information; receiving a private network address allocated to the user by the control plane; and performing, according to the public network address and the private network address, public and private network address translation on received service traffic of the user.
