Problems solved by technology

[0004] In the structural design of this network, the reliable operation of NVE is of great significance to the reliability of the network. Based on the existing technology, redundant backup between network virtual border devices cannot be realized, which is not conducive to the realization of cloud computing data center network. load balancing, and if an NVE device fails, users accessing through the NVE device will not be able to communicate with other terminals, which will affect system reliability and stability

Embodiment 1

[0071] Figure 5 It is a schematic diagram of the network structure of the network virtual boundary protection in Embodiment 1 of the present invention, in which a directory server (directory server) stores the mapping relationship between the MAC address and the IP address of the network. NVE1 and NVE2 form a network virtual boundary redundancy group to achieve dual-host (active-active) load balancing, that is, the information sent by VM1 can be encapsulated by NVE1 or NVE2. This network design can improve the reliability of network virtual border devices.

[0072] In this embodiment, the network virtual boundary member devices NVE1 and NVE2 both send their own address information and status information to the directory server. Synchronization and sharing of information within a network virtual border redundancy group.

[0073] When NVE1 fails and RT1 senses the failure, it quickly switches traffic to network virtual border member NVE2 through fast rerouting (FRR). Since th...

Embodiment 2

[0076] Image 6 It is a schematic diagram of the network structure of network virtual boundary protection in Embodiment 2 of the present invention. In this embodiment, when NVE1 learns a new user MAC address, including the MAC address of the terminal attached to the local end and the MAC address information of the remote end, it sends the information to the directory The server registers the address information. After receiving the registration information, the directory server needs to send the registration information to other devices in the network virtual border redundancy group, so as to realize information sharing of user address information in the network virtual border redundancy group. When a device in the network virtual border redundancy group fails, data traffic can be quickly switched.

[0077] In this embodiment, the process of automatic allocation of virtual addresses includes:

Abstract

The invention discloses a method for redundant backup between network virtual border devices. A network virtual border redundancy group including one or more network virtual border devices is set up. A directory server receives messages sent by network virtual border devices. The messages carry network The inner layer address, the outer layer address, the group ID of the virtual border device, and the tenant information of the network virtual border device; the directory server notifies the network virtual border to which the network virtual border device belongs to the information carried in the message according to the group ID Additional network virtual border devices in the redundancy group. The invention also correspondingly discloses a system for performing redundant backup between network virtual border devices, a directory server, and a network virtual border device. Through the scheme of the present invention, redundant backup between network virtual border devices can be realized, which is beneficial to the load balance of the cloud computing data center network and the improvement of system reliability and stability.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method, device and system for redundant backup between network virtual boundary (NVE) devices. Background technique [0002] The cloud computing data center network is very different from the traditional data center network. First, the cloud computing data center network is larger in scale than the traditional data center network, so the traditional two-layer technology has scalability in the cloud computing data center network. In addition, cloud computing will use virtualization technology extensively. For cloud computing data centers, one server can virtualize multiple virtual machines, and each virtual machine is assigned a virtual media access control (Media Access Control, MAC) Moreover, due to requirements such as disaster recovery backup and traffic load balancing between data centers, virtual machines may be migrated between one data center or even across data c...
