Description
Technical Field
The invention relates to the field of communication, in particular to a two-layer intercommunication method and device for an SDN data center.
Background
In the related art, a Software Defined Network (SDN) is a new Network deployment architecture, and the most important feature of the new Network deployment architecture is to separate a control plane from a data plane in a Network. The SDN control plane controls the global network resources, does not need to depend on the underlying network equipment, and shields the difference from the underlying network equipment. The user can customize any network routing and transmission rule strategies which are desired to be realized through the SDN control plane, so that the method is more flexible and intelligent.
With the development of cloud computing technology and the continuous increase of server scale, data centers based on the SDN architecture are widely applied. Deployment of data center multi-sites is a necessary trend for the "cloud". The data center has two main functions, namely capacity expansion and disaster recovery, so as to prevent accidental disasters.
SDN data center interconnections are mainly divided into two main categories: three layers of intercommunication and two layers of intercommunication. Although three-layer intercommunication of the data center can meet most of traditional application scenarios, with the application of virtualization technology, the requirements of virtual machine migration and virtual machine clustering are more and more vigorous, and three-layer intercommunication of the SDN data center cannot meet the development requirements of these new services.
The following technical concepts of virtual machine migration and virtual machine clustering are briefly introduced:
1) and migrating the virtual machine. The IP address and MAC of the server cannot change after the virtual machine migration. This requires that the virtual machines are located in the same two-tier network before and after the migration, i.e., there is two-tier network interconnection between sites.
2) A cluster of virtual machines. The cluster technology usually requires member servers to be interconnected through a two-layer network, and when the cluster scale is expanded or high reliability is considered, the member servers of the cluster may be deployed across sites, so that the two-layer network interconnection between the sites is required.
However, in the related art, two-layer interconnection and interworking between SDN data centers needs to solve how to open a two-layer forwarding channel of a virtual machine between two data centers. How to notify the virtual machine information in the data center to the remote data center is a problem that all two-layer interworking solutions need to be considered.
Different from the traditional data center, the host information notification of the SDN data center mainly adopts BGP EVPN, access equipment and gateways among the data centers are communicated through VXLAN, and data center GW is also communicated through VXLAN. However, if VXLAN between data centers is established between GWs (GW1 — GW2), the SDN controller needs to support BGP EVPN, and the requirements on the SDN controller are high.
Aiming at the problem that the difficulty in realizing two-layer interconnection between SDN data centers in the related technology is high, no effective solution is provided at present.

Detailed description of the preferred embodiment 2
The embodiment provides a data forwarding method for two-layer interconnection of an SDN data center, which is applied to a networking diagram shown in fig. 2 and includes the following steps:
step 201, in the networking shown in fig. 2, a processing flow of an Address Resolution Protocol (ARP) request message on the switch1 is as follows: since the VM1 and the VM2 belong to the same network segment, the VM1 directly requests the ARP of the VM2, the switch1 sends the ARP request message to the controller after receiving the ARP request message, and the SDN controller does not have the ARP corresponding to the VM2, and broadcasts the ARP request in the network where the VM1 is located.
Step 202, as shown in fig. 3, the processing flow of the ARP request message on GW1 is as follows: after receiving the ARP request message, the gateway device GW1 broadcasts the ARP request message on the network in which the host VM2 is located, and the broadcast message is sent from the L2 interface svi 2.
Step 203, as shown in fig. 3, the processing flow of the ARP request message on the legacy device 1 is as follows: the legacy device 1 receives the ARP request message from the svi2 interface, learns the source MAC (MAC1) in the message, and then sends a broadcast message to the legacy device 2. After legacy device 1 completes MAC1 learning of VM1, MAC1 is advertised to legacy device 2 through BGP EVPN.
Step 204, in the networking shown in fig. 2, the processing flow of the ARP request message on the conventional device 2 is as follows: after receiving the MAC1 forwarding table, the BGP EVPN stores the MAC1 forwarding table to the local. The legacy device 2 receives the ARP request message, and sends the ARP request message to the GW2 from the L2 interface.
Step 205, in the networking shown in fig. 2, the processing flow of the ARP request message on the GW2 is as follows: GW2 receives the ARP request message, and sends the message to the controller, and the SDN controller completes the source MAC (MAC1) learning and ARP response in the message.
Step 206, in the networking shown in fig. 2, the processing flow of the ARP reply message on the conventional device 2 is as follows: the legacy device 2 receives the ARP reply message, learns the source MAC address (MAC2), and notifies the MAC2 to the legacy device 1 through the BGP EVPN. And searching a MAC1 forwarding table, and sending an ARP response message to the traditional equipment 1.
Step 207, in the networking shown in fig. 2, the processing flow of the ARP reply message on the conventional device 1 is as follows: the legacy device 1 receives the ARP reply message, looks up the MAC table, and sends the message from the svi2 interface to the gateway device GW 1.
Step 208, in the networking shown in fig. 2, the processing flow of the ARP reply message in the gateway device GW 1: GW1 receives the ARP reply message, and sends the message to the controller, and the controller learns the source MAC (MAC 2). The controller sends the flow table of the MAC2 and the ARP reply message to the switch1 and sends the message to the switch 1.
Step 209, in the networking shown in fig. 2, the processing flow of the ARP reply message in the gateway device switch1 is as follows: the ARP reply message received by the switch1 is sent to the VM 1.
In step 210, in the networking shown in fig. 2, VM1 learns the MAC address (MAC2) of VM 2.
To this end, the two-tier forwarding path from VM1 to VM2 was successfully established, VM1 and VM2 were able to access each other, and VM1 and VM2 were also able to migrate in data center 1 and data center 2.
