  • Publication number: 20240205205
    Abstract: A packet sending method, a network device, and a program product are disclosed, and pertain to the field of segment routing technologies. The method includes: A network device sends a packet which includes a segment routing header SRH and a payload, the SRH includes an encrypted field and an unencrypted field, the encrypted field includes at least an encrypted SID list, and the SID list indicates a transmission path of the packet. A SID list in an SRH of an SRv6 packet transmitted over a POP network is encrypted, thereby protecting SID information from being leaked. In addition, an intermediate node on a packet transmission path only needs to decrypt an encrypted field in the SRH to determine a next hop from the SID list, and does not need to decrypt the payload. This improves forwarding efficiency of the network device and protects secure transmission of the payload.

  • Publication number: 20230336377
    Abstract: Embodiments of this application disclose a packet forwarding method and apparatus, and a network system, and belong to the field of communication technologies. The method includes: When sending a first packet, first CPE may perform inner encapsulation and outer encapsulation on the first packet. The inner tunnel is an end-to-end tunnel between the first CPE and second CPE, and a second destination address in the outer tunnel encapsulation may be an address of a GW. It can be learned that in this application, an end-to-end inner tunnel may be established between the first CPE and the second CPE, and the inner tunnel may pass through a backbone network via the GW and then reach the second CPE on a basis that an outer tunnel is established so that the first CPE and the GW communicate with each other.

  • Publication number: 20230208680
    Abstract: Embodiments of this application disclose a communication method, and a communications apparatus, device, and system. When customer premise equipment has an overlay virtual network instance, a loopback interface is established in the overlay virtual network instance, and an IP address is allocated to the loopback interface. In addition, the customer premise equipment establishes a transmission path to a server side based on the overlay virtual network instance, and sends a packet to the server side by using the transmission path. The packet includes the IP address of the loopback interface, to register with a server by using the IP address, so that the server can identify the customer premise equipment based on the IP address. In the method, when the customer premise equipment sends the packet by using the transmission path, a source address of the sent packet is the IP address of the loopback interface in the overlay virtual network instance.

  • Patent number: 11432368
    Abstract: A network access method includes calculating, by a proxy coordination device, a network access parameter based on a link quality parameter of the proxy coordination device in a power line communication (PLC) network, where the network access parameter includes link overheads, and the link overheads are used to indicate overheads for performing network access by a station device through the proxy coordination device based on radio frequency (RF) communication, and sending, by the proxy coordination device, a destination oriented directed acyclic graph (DODAG) information object (DIO) packet, where the DIO packet includes the link overheads.

  • Publication number: 20210007180
    Abstract: This application provides a network access method for hybrid networking, a proxy coordination device, and a station device. The method includes: calculating, by a proxy coordination device, a network access parameter based on a link quality parameter of the proxy coordination device in a PLC network, where the network access parameter includes link overheads, and the link overheads are used to indicate overheads for performing network access by a station device through the proxy coordination device based on radio frequency RF communication; and sending, by the proxy coordination device, a DIO packet, where the DIO packet includes the link overheads. As such the station device can select a better network access path based on the link overheads, helping to improve operation efficiency of a hybrid network.
