Problems solved by technology

[0011] In the prior art, after the DED assigns the active VLAN to each multi-homing ED, unless the EVI network changes, for example: a multi-homing ED in the site joins or exits the EVI network, or a multi-homing ED adds or deletes an extended VLAN, etc. It will cause the active VLAN to change passively, otherwise the multi-homing ED will not actively change its own active VLAN
In practical applications, different VLANs carry different services, and the data traffic on them is also quite different. Evenly distributing active VLANs according to the number of VLANs may lead to unbalanced traffic among multiple multi-homing EDs, and some multi-homing The traffic from the ED to the remote site is too large, and the bandwidth is not enough, while the traffic from other multi-homing EDs to the remote site is small, and a large amount of bandwidth is idle.

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] In the present invention, a data center site applying EVI technology is called an EVI site, and tunnels through the public network, such as Generic Routing Encapsulation (GRE) tunnels, are established between EDs in different EVI sites, and Layer 2 interconnection is realized through the established tunnels.

[0031] see figure 2 , figure 2 It is a flowchart of a dynamic adjustment method for activating a VLAN in an embodiment of the present invention, comprising the following steps:

[0032] Step 201, the multi-homing ED measures the traffic of each activated VLAN of itself on the public network side; when receiving the traffic request message sent by the DED that the current device participates in election, returns the traf...

Abstract

The invention provides a dynamic regulation method and device for an active VLAN (Virtual Local Area Network). According to the method, a DED (Designated Edge Device) obtains the flow information of each active VLAN measured by a multi-homing ED (Edge Device), based on the flow information, the active VLAN of each multi-homing ED is regulated as a preset rule, and the regulated active VLAN is distributed to each multi-homing ED again. Due to the adoption of the method and device, the flow balance among the multi-homing EDs is maintained.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for dynamically adjusting active VLANs between multi-homing edge devices (EDs) in an Ethernet virtualization interconnection (Ethernet virtualization Interconnection, EVI) site. Background technique [0002] With the rapid development of the Internet, the geographical span of the network is getting wider and wider. In order to provide better services, users usually deploy data centers in different places. These data centers often implement load sharing and high reliability through free migration of virtual machines. Since the virtual machine migration process is transparent to users and the IP address cannot be changed, it is required to implement Layer 2 network interconnection between data centers in different places. [0003] EVI technology divides the overall network into two parts: the core network (public network) and the site network (p...
