Problems solved by technology

However, in this solution, since the source host gateway does not have routing link data, all traffic between the source virtual machine in one host and the source virtual machines of other hosts needs to be forwarded through the virtual routing gateway, which may easily lead to traffic load on the virtual routing gateway. Too large, wasting the bandwidth resources of the virtual routing gateway

Embodiment Construction

[0044] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0045] Referring to FIG. 1 , it is a schematic structural diagram of a routing management system according to an embodiment of the present application. In FIG. 1 , a controller 110 , a virtual routing gateway (VGM) 120 and a host machine 130 are included, and the host machine 130 includes a virtual machine (VM) 131 and a host machine gateway (HGW) 132 .

[0046] Wherein, the main function of the controller 110 is: processing three types of user requests for production, release, and migration of virtual machines. The main function of the virtual routing gateway is to store the full amount of routing link data and make changes according to the incremental routing data issued by the controller. In addition,...

Abstract

The embodiment of the application provides a routing link management method and system, a virtual routing gateway and a host gateway, relating to the technical field of computers. According to the embodiment of the application, the method includes the following steps: for a message sent by a virtual machine, when a source host gateway corresponding to the virtual machine does not find routing linkdata corresponding to the message locally, the message is forwarded to the virtual routing gateway; after the virtual routing gateway finds the routing link data corresponding to the message locallyfor the received message, the virtual routing gateway forwards the message to a destination host gateway according to the routing link data and returns the routing link data to the source host gateway; and the source host gateway records the routing link data to a local source host according to the received routing link data. Thereby, the host gateway can quickly obtain the routing link data thatis required thereby, the consumption of the host memory can be reduced, and the excessive traffic load of the virtual routing gateway can be avoided.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a routing link management method and system, a virtual routing gateway and a host gateway. Background technique [0002] In cloud services, there is a private network VPC (Virtual Private Cloud, virtual private cloud). The private network VPC is a dynamically configured pool of public cloud computing resources, which requires the use of encryption protocols, tunneling protocols, and other security procedures. Data transfer between private companies and cloud service providers. A VPC basically turns the provider's multi-tenant architecture into a single-tenant architecture. In a dedicated network, it can host hundreds of thousands or more source virtual machines, and these source virtual machines are distributed on a large number of different hosts in the cloud cluster; and each host may host multiple hosts respectively. source virtual machine for a VPC. [0003] Th...
