Embodiment 1

[0045] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of a network data flow forwarding method according to the present invention.

[0046] Step S10, receiving the network data stream information packet, and analyzing the information packet to obtain the analysis result;

[0047] In this embodiment, after the transponder receives the network data message, it stores the received information packet, analyzes the information packet, and obtains a corresponding analysis result, wherein the analysis result includes: identification ID, source transponder number and Its port number, data type, label, source address, destination address and other required information. In addition, in this embodiment, the manner of parsing the information packet is not limited, and it depends on the actual situation.

[0048] Step S20, identifying the analysis result, and confirming the packet type corresponding to the information packet;

[0049] In this embodiment, when...

Embodiment 2

[0057] Based on the first embodiment, step S30 in the first embodiment includes in detail:

[0058] (1) Identify the type of information packet as a signaling packet

[0059] Specifically, when it is identified that the type of the information packet is a signaling packet, the entire information packet is directly sent to the controller, and then corresponding measures are taken according to the analysis and calculation results of the information packet by the controller itself, wherein the corresponding measures include local Respond and send unicast or multicast table to forwarder. In this embodiment, the signaling packet includes ARP / RARP, ICMP, routing information, IGMP multicast signaling, and the like.

[0060] For example, when the received signaling packet is an address resolution packet, the forwarder directly sends the information packet to the controller. At this time, the controller confirms that the information packet is an address resolution packet by analyzing ...

Abstract

The invention discloses a network data stream forwarding method, comprising the following steps: receiving network data stream information packets, and analyzing the information packets to obtain an analysis result; identifying the analysis results, and confirming that the information packets correspond to The packet category, wherein, the packet category includes at least signaling packets, unicast data packets, broadcast data packets, multicast data packets; according to the packet category of the information packet, the information packet is processed accordingly, wherein, The processing at least includes: forwarding the information packet directly or interacting with the controller and forwarding the information packet according to the interaction result. The invention also discloses a network data stream forwarding device, system and readable storage medium. The invention realizes the parsing and identification of the information packet on the transponder and corresponding processing, reduces the processing load of the controller, and accelerates the processing speed of the data flow.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a network data flow forwarding method, device, system and computer-readable storage medium. Background technique [0002] In the way of data transmission in the existing network, the forwarder is mainly used to analyze the relevant matching field of the information packet, and use this matching field to search the local forwarding flow table to forward the information packet. If there is no match in the local forwarding flow table, then The entire packet needs to be sent to the controller, and the controller re-analyzes the information packet and extracts the information required to determine the forwarding path, calculates the path with an appropriate algorithm according to the configured strategy and intent, and sends the obtained forwarding path to the forwarder for further processing. For the forwarder to forward the information packet according to the n...
