  • Packet processing method, device, and packet processing system
    Patent number: 10868697
    Abstract: A packet processing method, a device, and a packet processing system are provided. The method includes: generating, by a VTEP device at one end of a VXLAN tunnel, a PPP over VXLAN packet that carries control information, and transmitting the PPP over VXLAN packet to a VTEP device at the other end of the VXLAN tunnel by using the VXLAN tunnel. The VTEP device at the other end of the VXLAN tunnel may perform, based on the control information in the PPP over VXLAN packet, a function defined in PPP. In this way, a VXLAN control plane is implemented by using the PPP, and overheads and complexity of implementing the VXLAN control plane are reduced.

  • Method and gateway for obtaining route according to requirement
    Patent number: 10447593
    Abstract: A method and gateway obtain a route according to a requirement. The method includes: a first gateway receives a first packet; the first gateway searches a forwarding table for a next hop of a first IP address in the first packet, wherein the search fails; the first gateway sends a second packet carrying the first IP address to at least one gateway; the first gateway receives a third packet from a second gateway; and the first gateway writes an address of the second gateway into the forwarding table as a next hop address of the first IP address.
