A traffic forwarding method based on a virtual switch cluster is described. The method includes setting an aggregation group member list to store information about all the members of an aggregation group; setting an aggregation group traffic forwarding member list to store information of aggregation group members for forwarding traffic, wherein the list in an initial state only containing information about local members of the aggregation group; and when it is determined that traffic of a physical device exceeds the total bandwidth of the members in the aggregation group traffic forwarding member list or a threshold value related to the total bandwidth, selecting a nonlocal member from the aggregation group member list and adding the same into the aggregation group traffic forwarding member list, and forwarding traffic according to the changed aggregation group traffic forwarding member list. A traffic forwarding system based on a virtual switch cluster is also described. The disclosure can implement traffic forwarding in a virtual switch cluster scene on the premise of occupying limited bandwidth of a stack link as small as possible, thereby ensuring the traffic forwarding performance in the virtual switch cluster scene.

The embodiment of the invention discloses a private network application identification system, method, SDN controller, and P equipment, relates to the field of data communication, and realizes visualization of private network application traffic in a service provider network. The system includes at least a P device and an SDN controller, wherein the SDN controller is configured to receive from the P device the egress PE device address corresponding to the MPLS message and the egress PE device allocation in the MPLS message compare the received address of the egress PE device and the VPN label assigned by the egress PE device with the pre-acquired PE device address, the corresponding relationship between the VPN label assigned by the PE device and the VPN, and determine The VPN corresponding to the MPLS message, and determine the private network application corresponding to the MPLS message in combination with the message feature information.

The embodiment of the present invention discloses a data packet processing method, controller and system. The method includes: the controller receives a data packet reported by a switch that does not match a forwarding rule; after determining that the type of the data packet is a broadcast data packet, Generate a forwarding rule for the data packet, the forwarding rule includes an action attribute of discarding; send the forwarding rule of the data packet to the switch, so that when the switch receives the data packet again, according to the forwarding rule The action attribute discards the packet. Because the present invention does not need to shield the ports of the switch, it can avoid the broadcast storm in the network, so for the fully connected network, the forwarding capability of the port and the number of available transmission links in the network are guaranteed, and the transmission in the network is correspondingly improved. link utilization.

The embodiment of the present invention discloses a message forwarding method, device and system. In a forwarding network including a controller, a user side LB, a vBNG and a network side LB, the network side LB receives a message sent from the network side to the user side When the first packet forwarded by the target terminal of the target terminal, the first packet of the pre-planned network-side LB can be determined by matching the destination identifier used to identify the target terminal of the first packet to the first sharing entry. a forwarding path from the outgoing interface to the first forwarding unit that processes the online of the target terminal, so that the first packet sent to the target terminal can be accurately forwarded to the first forwarding unit that processes the online of the target terminal, It avoids that the message forwarded from the network side to the user side may be forwarded to an unsuitable forwarding unit in the vBNG, thereby reducing the need for the vBNG to forward the message received from the network side across VMs, and ensuring that the vBNG forwarding performance.

A method and device for implementing RFC2544 in a VPWS environment, including a multi-core CPU as the core of the control plane, running multiple control plane protocols, and generating various entries of VPWS and RFC2544 required when the forwarding plane processes data packets, and the multi-core CPU is also used to generate RFC2544 active end test data packet; the forwarding plane is implemented by the switch chip and FPGA, the switch chip and FPGA cooperate with each other to process the RFC2544 test data packet in the VPWS environment; for the RFC2544 active end packet, the multi-core CPU generates the test data packet and writes it to FPGA, FPGA Send the test traffic to the switch chip, and the switch chip sends the test traffic; for the RFC2544 passive end, after the switch chip receives and processes the packets, it sends the test traffic to the FPGA, and the FPGA sends the test traffic to the switch chip again, and the switch chip sends the test traffic The traffic is sent out; for the RFC2544 active end to receive packets, the switch chip will send the test traffic to the FPGA after receiving the packets, and the FPGA will perform the final calculation of the RFC2544 test parameters on the test traffic; it can realize the line-speed forwarding of the device port to ensure the integrity of the device port. Forwarding performance.
