2 results about "Reverse path forwarding" patented technology

The application discloses a flow forwarding method and device, computer equipment and a storage medium. The method can be applied to the field of information security technology, and specifically can include: in the case that the original forwarding path of target message flow cannot forward the target message flow, generating a new forwarding path for the target message flow; querying whether a unicast reverse path forwarding (uRPF) detection is configured in a new forwarding interface in the new forwarding path; if yes, determining a detection mode of the uRPF detection of the new forwarding interface according to the message type of the target message flow; and controlling the new forwarding interface to perform forwarding processing on the target message flow according to the detection mode. The above scheme can ensure normal flow forwarding.

This application discloses a communication method and a related apparatus, and relates to the field of communication technologies. The method is applied to a software defined wide area network (SD-WAN) overlay network. A customer premise equipment (CPE) autonomously generates an SD-WAN overlay routing table, so that communication reliability and flexibility are improved. A route reflector (RR) specifies an overlay multicast reverse path forwarding (RPF) route to the CPE to implement SD-WAN overlay multicast communication, and the CPE does not need to perform path computation autonomously, so that a computing power requirement of the CPE is reduced. An identifier of the CPE and an identifier of a site are carried in a multicast join message to implement the SD-WAN overlay multicast communication. A standard IP header is carried in a multicast service packet to implement the SD-WAN overlay multicast communication, so that generalization, applicability, and compatibility are improved.
