摘要： This application provides a VXLAN packet processing method, a device, and a system. After determining that a data packet sent by a CE device is a BUM packet, a PE device encapsulates the BUM packet to generate a VXLAN packet including an ESI label and a VXLAN packet including a BUM traffic label. The VXLAN packet including the ESI label is sent to an active-active gateway, so that the gateway can block forwarding of traffic to the CE device by using an interface configured with an ESI, to avoid a loop between the PE device and the CE device. The VXLAN packet including the BUM traffic label is sent to a remote PE, to block forwarding of the VXLAN packet to the CE device by using a secondary DF interface, thereby avoiding a multi-packet problem. Reliability of an EVPN VXLAN gateway is improved by using this application.

摘要： A VXLAN packet forwarding method, device, and system are disclosed. The method includes: setting, by a local VTEP device based on a priority of a VXLAN tunnel, tunnel states of at least two VXLAN tunnels that are connected to the local VTEP device; sending the tunnel states of the VXLAN tunnels to at least two peer VTEP devices, where the at least two VXLAN tunnels are in a one-to-one correspondence with the at least two peer VTEP devices; and separately confirming, by the at least two peer VTEP devices, the received tunnel states of the VXLAN tunnels. A VXLAN tunnel in an Active state is in a working state, and a VXLAN tunnel in an Inactive state is in a non-working state, thereby improving a redundancy protection capability of a VXLAN network.

摘要： This application discloses a method and an apparatus for obtaining a shared maximum segment size MSS, and a storage medium, and belongs to the field of communications technologies. In this application, a first device may obtain a first parameter after a Transmission Control Protocol TCP connection is established, obtain a first MSS based on the first parameter, and further obtain a first shared MSS based on the first MSS and a second MSS. After the TCP connection is established, when a parameter of the TCP connection changes, the first device updates a shared MSS based on a changed parameter, and may use an updated shared MSS to transmit a packet. This helps save network resources and improve transmission reliability.

摘要： This application provides a data traffic processing method, a device, and a system. The method includes: receiving, by a first network device on a first link, a first VXLAN packet sent by a second network device, where the first VXLAN packet includes a first sequence number and a first service packet; decapsulating, by the first network device, the first VXLAN packet; receiving, by the first network device on a second link, a second VXLAN packet sent by the second network device, where the second VXLAN packet includes a second sequence number and a second service packet; and when the first network device determines that the second sequence number is a next sequence number of the first sequence number, decapsulating, by the first network device, the second VXLAN packet. This reduces packet disorder, and increases bandwidth utilization of a VXLAN tunnel.
