9 results about "IP tunnel" patented technology

A client device communicates with a network via a host device as an intermediary through a virtual link technique in which an Internet Protocol (IP) tunnel is established between the client device and the host device, and a plurality of physical links between the host device and the client device are assigned or otherwise associated with the IP tunnel such that the IP tunnel acts as a single virtual link between the client device and the host device, with fixed IP addresses, but therein data can be communicated between the client device and the host device on different physical links according to routing policy that includes routing rules for routing data packets between the different physical links according to one or more parameters.

The concepts and technologies disclosed herein are directed to software-defined wide-area network (“SD-WAN”) self-service for service assurance. The proposed SD-WAN self-service solution can be used for any policy-driven system that automatically troubleshoots the problems resulting from hybrid SD-WAN network activities, including virtual private network (“VPN”), IP tunnel, IPSec, and security policies. According to one aspect disclosed herein, a method can check network configurations, analyze switch responses, and locate network problems quickly. Moreover, the method can test the functionality of a rules-based troubleshooting software effectively without employing expensive testing equipment and with minimal human intervention. Without the disclosed solution, telecommunications service providers may have to hire more software engineers who understand SDN and cloud technologies to effectively troubleshoot SD-WAN network connectivity issues, including issues caused by virtual network function (“VNF”), virtual machine (“VM”), and SDN switches. Thus, this labor-intensive solution is not only expensive, but also not immune to human error.

The invention relates to a communication method and device, communication equipment, a readable storage medium and a computer program product. The method comprises: sending a first NAS message to an AMF network element, the first NAS message carrying a wireless local area network user plane access identifier, the wireless local area network user plane access identifier being used for indicating that a user plane data bearer is established on a wireless local area network; receiving a second NAS message sent by the AMF network element, wherein the second NAS message carries the IP address of the gateway; the IP address of the gateway is acquired by the AMF network element in response to the wireless local area network user plane access identifier; and establishing an IP tunnel between the UE and the gateway based on the wireless local area network IP address of the UE and the IP address of the gateway. By adopting the method, a mode for accessing the 5G core network from the non-3GPP access network, which is wider in application range, is provided.

Technologies directed to Internet Protocol (IP) tunnels for cloud-based applications on a streaming device are described. One method receives a request to execute a streaming application hosted by the remote computing device. The method establishes a first IP tunnel with the remote computing device using a first virtual interface. The method establishes a second IP tunnel with a container executing the streaming application using a second virtual interface. The method establishing routing between the second virtual interface and a local network interface. The method communicates data with the streaming application over the second IP tunnel.

The invention provides a method for determining tunnel connectivity. The method is applied to a first communication device supporting BFD (Bidirectional Forwarding Detection). The method comprises the following steps: generating and sending a first message, wherein the first message is a BFD (Bidirectional Forwarding Detection) message which is initiated by single-end equipment and is used for detecting the connectivity of a bidirectional tunnel; the first message comprises outer-layer tunnel information, inner-layer tunnel information and BFD control information. The outer-layer tunnel information indicates a first tunnel from the first communication device to the second communication device, and the inner-layer tunnel information indicates a second tunnel from the second communication device to the first communication device. The first tunnel and the second tunnel are IP tunnels. If both the first tunnel and the second tunnel have no fault, the first message is finally forwarded to the first communication device based on the outer-layer tunnel information and the inner-layer tunnel information, and correspondingly, the first communication device can determine the connectivity of the two-way tunnel. By using the scheme, even if the IP tunnel only comprises a single endpoint to support the BFD technology, the connectivity of the bidirectional tunnel can be determined.

A method for establishing an IPCON Mission Critical Data Internet Protocol Connectivity MCData session in a communications network according to the 3GPP MCS 3rd Generation Partnership Program Mission Critical System standard. The network includes an emitting MCData entity, a destination MCData entity and an MCData transport service connected to the emitting and destination MCData entities. The method includes obtaining, from the emitting MCData entity, a DPPK MCData Payload Protection Key and a DPPK-ID MCData Payload Protection Key Identifier, transmitting a SIP-INVITE message comprising the DPPK key and the DPPK-IK key identifier, from the emitting MCData entity to the destination MCData entity via the MCData transport service, authenticating the message, by the destination MCData entity, and determining the DPPK key and the DPPK-ID key identifier, by the destination MCData entity, and establishing an IP tunnel between the emitting MCData entity and the destination MCData entity.

The present application relates to communication methods, an apparatus, a communication device, a readable storage medium and a computer program product. A method comprises: sending to an AMF network element a first NAS message, the first NAS message carrying a wireless local area network user plane access identifier, and the wireless local area network user plane access identifier being used for indicating that a user plane data bearer is established on a wireless local area network; receiving a second NAS message sent by the AMF network element, the second NAS message carrying an IP address of a gateway, and the IP address of the gateway being acquired by the AMF network element in response to the wireless local area network user plane access identifier; and, on the basis of a wireless local area network IP address of the UE and the IP address of the gateway, establishing an IP tunnel between the UE and the gateway.
