[0070] see Figure 4B , is the flow chart of the third embodiment of the method for broadcasting data packets of the present invention, which embodiment combines Figure 4A Describe the processing of the packet in detail:

[0071] Step 401: the switch receives the data packet.

[0072] combine Figure 4A , assuming that port 2 of switch 4 receives the packet.

[0073] Step 402: The switch does not match the forwarding rule of the data packet, and reports the data packet to the controller.

[0074] Assume that the data packet received by port 2 of switch 4 is the data packet received by the switch 4 for the first time, so the switch 4 does not match the forwarding rule of the data packet, and the switch 4 reports the data packet to the controller, requesting the controller to be The data packet is delivered with a forwarding policy.

[0075] Step 403: The controller determines that the data packet is a broadcast data packet, and determines that the attribute information of...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data packet processing method, controller and system. Background technique [0002] Generally, data centers adopt a fully connected network structure to improve network communication efficiency. A fully connected network structure can be as follows: switches on different layers are connected in pairs, and each switch at the bottom layer is connected to a certain number of hosts. When a switch in the network receives a broadcast data packet, it needs to flood the broadcast data packet on all ports except the receiving port in the virtual local area network (Virtual Local Area Network, VLAN) to which the switch belongs. However, when there is a loop in the fully connected network, the broadcast data packet may be repeatedly broadcast on the formed loop, thus causing a broadcast storm. [0003] A fully connected network can be implemented based on software-defined n...
