Problems solved by technology

In the stacking mode, the uplink and downlink of the gateway physical device does not perceive the actual status switching of the gateway. There is a problem that the two devices must be upgraded at the same time when the version is upgraded, and the network interruption time is long.
Moreover, the traditional data center network does not have a centralized control point, which makes it impossible to globally manage the data center network traffic and uniformly schedule the network traffic, resulting in the problem of high operation and maintenance complexity.

Embodiment 1

[0061] An embodiment of the present invention provides a data center traffic interworking method, setting an SDN controller, the SDN controller, such as figure 1 shown, including:

[0062] Business configuration module 101: used to configure business-related information;

[0063] Device access management module 102: used to manage the information of gateway physical devices accessing the SDN controller;

[0064] Routing management module 103: used to manage the routing information of the data center;

[0065] Link management module 105: used to collect the device topology of the data center, and perceive link information, and perform path calculation on the link according to the routing information of the routing management module 103, to obtain the optimal network path;

[0066] Sending and receiving packet processing module 104: for processing received protocol messages;

[0067] and

[0068] Device driver module 106: used to arrange gateway physical devices according to...

Embodiment 2

[0101] The SDN controller is the core component for managing the data center network. The modules contained in the SDN controller and the interaction diagram of each module are as follows: figure 1 As shown, the SDN controller includes a service configuration module 101, a device access management module 102, a routing management module 103, a link management module 105, a sending and receiving packet processing module 104, and a device driver module.

[0102] The service configuration module 101 is configured to configure service-related information, mainly including VDC network and DCI service-related configuration information.

[0103] The device access management module 102 is used to manage related information of the connected gateway physical device, and is used when the SDN controller orchestrates the gateway physical device.

[0104] The routing management module 103 is configured to manage routing information related to the data center network, including routing infor...

Embodiment 3

[0138] Such as Figure 12 As shown in the figure, in the scenario of north-south traffic interworking between the egress of the data center and the external network, the main gateway device fails, and the main steps are as follows:

[0139] In the first step, the SDN controller is connected to the gateway physical device. The VTEP Group information is configured on the SDN controller. The VTEPGroup attribute is MC-LAG. The two gateway physical devices present a logical device on the network topology layer.

[0140] In the second step, the SDN controller configures the MC-LAG link and Peer-Link information of the gateway physical device, and the two cross-rack stacking ports configured as MC-LAG are virtualized into one logical port, and the ports not configured with MC-LAG, Also occupies a global number on the logical device. Peer-Link can be displayed on the management plane and can be configured accordingly.

[0141] The third step is to create a virtual router on the Open...

Abstract

The invention discloses a data center traffic intercommunication method, device, equipment and storage medium. Among them, the data center traffic intercommunication method is characterized in that an SDN controller is set, and the method includes: configuring at least two gateway physical devices connected to the SDN controller as a logical device, wherein the gateway physical devices The physical port is a logical port of the logical device; traffic intercommunication between the data center and the external network is realized based on an optimal network path and an association relationship, wherein the optimal network path is a physical link from the logical port to the gateway physical device The optimal path of the port, the association relationship is the relationship between the physical port of the gateway physical device and the external network. By setting up the SDN controller, the logical devices configured under the control of the SDN controller can globally manage the traffic of the data center, so as to uniformly schedule the network traffic and achieve the effect of reducing the complexity of operation and maintenance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data center flow interworking method, device, equipment and storage medium. Background technique [0002] With the development of cloud computing and mobile Internet applications, complex interactive applications appear in the new IDC (Internet Data Center, Internet Data Center), especially massive data access and process calls, making a single IDC unable to meet the needs of Internet applications. In order to meet the needs of applications, different IDCs must be integrated into a unified resource pool. At the same time, as a bearer network connecting IDCs, it must support various upper-layer applications, such as virtualization between DCs (Data Centers, data centers), real-time migration of VMs (Virtual Machines, virtual machines), and tenant isolation across DCs. Wait. [0003] With the rapid development of ICP (Internet Content Provider, network content service provider...
