Embodiment 1
[0069] Figure 8 It is a schematic diagram of an application scenario of single-homing access of a user equipment to a layered network according to Embodiment 1 of the present invention, as shown in Figure 8 As shown, in this embodiment, the edge nodes 1, 2, 3, and 4 supporting OpenFlow in the stacked network are respectively connected to the OpenFlow controller through the OpenFlow channel, and the user equipment is single-homed to the stacked network through the edge node 1.
[0070] In this embodiment, the OpenFlow controller and the edge nodes supporting OpenFlow in the overlay network need to perform the following steps:
[0071] In step 1, the OpenFlow controller issues a flow table for address mapping relationship self-learning to edge nodes 1, 2, 3, and 4 supporting OpenFlow, and the flow table includes an action of creating a flow table and an action of creating a group table.
[0072] Among them, the action of creating a flow table and the action of creating a grou...
Embodiment 2
[0081] Figure 9 is a schematic diagram of an application scenario of user equipment dual-homing access to a layered network according to Embodiment 2 of the present invention, as shown in Figure 9 As shown, in this embodiment, the edge nodes 1, 2, 3, and 4 supporting OpenFlow in the cascade network are respectively connected to the OpenFlow controller through the OpenFlow channel, and the user equipment is dual-homed to the cascade network through the edge nodes 1 and 2.
[0082] In this embodiment, the OpenFlow controller and the edge nodes supporting OpenFlow in the overlay network need to perform the following steps:
[0083] In step 1, the OpenFlow controller issues a flow table for address mapping relationship self-learning to edge nodes 1, 2, 3, and 4 supporting OpenFlow, and the flow table includes an action of creating a flow table and an action of creating a group table.
[0084] Among them, the action of creating a flow table and the action of creating a group tab...

Abstract
The present invention provides a method and device for learning an address mapping relationship, wherein the method includes: an edge node in a cascaded network receives entry information from an OpenFlow controller, wherein the entry information includes instructions for creating a flow table The first instruction information and the second instruction information for instructing to create a group table associated with the flow table; the edge node receives the data packet; the edge node creates a flow table for the data packet according to the entry information and the flow table associated with the flow table group table, and store the obtained address mapping relationship corresponding to the data packet into the created flow table and group table. The invention solves the problem that the OpenFlow protocol in the related art cannot realize the self-learning of the address mapping relationship in the stacked network, thereby reducing the number of data packets that need to be sent to the controller, and reducing the pressure on the OpenFlow controller and the OpenFlow channel in the stacked network.
Description
technical field [0001] The present invention relates to the field of communications, in particular to a method and device for learning address mapping relationships. Background technique [0002] The OpenFlow network adopts an architecture in which the control plane and the forwarding plane are separated. figure 1 It is a schematic diagram of an OpenFlow network component architecture according to related technologies. Such as figure 1 As shown, the control plane of the OpenFlow network is realized by the OpenFlow controller, the forwarding plane of the OpenFlow network is realized by the OpenFlow switch, and the OpenFlow protocol is run between the OpenFlow controller and the OpenFlow switch; The flow table (Flow Table) of the match field (Match Field) and the group table (Group Table) containing one or more action sets (ActionBucket) can achieve the purpose of controlling data forwarding and realize the separation of data forwarding and routing control. [0003] Accordi...
