A method for providing network connectivity to at least one client device includes: connecting the at least one client device to an access gateway device to create a local area network of the access gateway device; and connecting the access gateway device to an internet protocol edge function. The at least one client device is connected to a telecommunications network via the access gateway device and the internet protocol edge function. In order to provide the network connectivity to the at least one client device, a network connectivity link is provided, the network connectivity link comprising: a local area network-segment between the at least one client device and the access gateway device, and a wide area network-segment between the access gateway device and the internet protocol edge function.

An information processing apparatus that communicates with a communication apparatus includes a connecting unit that connects to a first access point in the communication apparatus, a connection-information acquisition unit that acquires connection information for connecting to a second access point in the communication apparatus via the first access point, a storage unit that stores the acquired connection information in a memory, and a receiving unit that receives an instruction to transmit data. Upon receipt of an instruction to transmit data when the connecting unit is not connected to the second access point, the connecting unit connects to the second access point using the stored connection information stored in the storage unit, and when the connecting unit is connected to the second access point, the first access point is disabled.

A distributed radio frequency communication system facilitates communication between a wireless terminal and a core network. The system includes a remote radio unit (RRU) coupled to at least one antenna to communicate with the wireless terminal. The RRU includes electronic circuitry to perform at least a first portion of a first-level protocol of a radio access network (RAN) for communicating between the wireless terminal and the core network. The system also includes a baseband unit (BBU) coupled to the core network, and configured to perform at least a second-level protocol of the RAN. A fronthaul link is coupled to the BBU and the RRU. The fronthaul link utilizes an adaptive fronthaul protocol for communication between the BBU and the RRU. The adaptive fronthaul protocol has provisions for adapting to conditions of the fronthaul link and radio network by changing the way data is communicated over the fronthaul link.

A first network device receives an association relationship sent by a second network device, where the association relationship includes an association relationship between a first path and a second path. The first network device generates first routing information between the first network device and a target network device based on the association relationship, where the first routing information is used by the first network device to send a packet to the target network device through the first path, and when a cross-slice condition is met, the first routing information is used by the first network device to send a packet to the target network device through the second path.

Cloud delivered access may be provided. A network device may provide a client device with a pre-authentication virtual network and a pre-authentication address. Next, a policy may be received in response to the client device authenticating. The client device may then be moved to a post-authentication virtual network based on the policy. A post-authentication address may then be obtained for the client device in response to moving the client device to a post-authentication virtual network. Traffic for the client device may then be translated to the post-authentication address.

A wireless communication device (alternatively, device, WDEV, etc.) includes a processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. A WDEV selects a resource unit (RU) from an orthogonal frequency division multiple access (OFDMA) sub-carrier plan for use in supporting communications with another WDEV. The WDEV transmits a signal to the other WDEV that includes information that specifies the RU that is selected from the OFDMA sub-carrier plan and then supports communications with the other WDEV using the RU that is selected from the OFDMA sub-carrier plan. The OFDMA sub-carrier plan includes multiple OFDMA sub-carrier sub-plans of different sized RUs and null sub-carriers.

According to one aspect, a communication apparatus is provided which is on a LAN and coupled to a server via an external network involving a NAT traversal with a router of the LAN. The communication apparatus is configured to determine a configuration of the router of the LAN; and request the server to transmit a NAT update request packet to the router, which is registered in the server and performs the NAT traversal, when it is determined that the configuration of the router of the LAN is in two or more stages.

A distributed radio frequency communication system includes a remote radio unit (RRU and a baseband unit (BBU) and facilitates communication between a wireless terminal and a core network. The RRU receives a radio frequency signal from a wireless terminal and convert the radio frequency signal to digital baseband samples using receiver circuitry and an analog-to-digital converter. The RRU then adaptively compresses the digital baseband samples, using adaptive compression circuitry, to create fronthaul uplink information, and sends the fronthaul uplink information over a fronthaul link to the BBU using an adaptive fronthaul protocol. The RRU also receives fronthaul downlink information over a fronthaul link from the BBU using an adaptive fronthaul protocol and generates frequency-domain samples, based on the fronthaul downlink information received. It then creates time-domain baseband samples from the frequency-domain samples and converts the time-domain baseband samples into a radio frequency signal to send to the wireless terminal.

A first edge node in a first site network receives an Internet Protocol (IP) address resolving request packet from a device in the first site network. The first edge node replaces a source Media Access Control (MAC) address of an Ethernet frame header and a sender MAC address in a packet body of the IP address resolving request packet with the MAC address of the first edge node. The first edge node forwards the IP address resolving request packet to a second site network via a tunnel linking the first site network and the second site network.

A device, system and method, according to various embodiments, can include, for example, a hybrid cloud network, one or more personal cloud virtual LANs, and a home area network. The hybrid cloud network can be configured to provide public access and private access. The one or more personal cloud virtual LANs are provided at an overlapping segment of the hybrid cloud network to provide privacy within the hybrid cloud network. The home area network can include a single purpose computer configured as a gateway for the hybrid cloud network and configured to establish a site-to-site secure connection with the one or more personal cloud virtual LANs.
