The invention discloses a communication method, a communication system and a control node for distributed networks. The communication method is applied to the control node, and includes receiving exterior gateway adding requests transmitted by first tenants in cloud platforms; selecting at least one of computational nodes on the basis of the exterior gateway adding requests and utilizing the selected computational nodes as representative nodes of the first tenants. The first tenants belong to the computational nodes. The representative nodes are media for being communicated with the exterior networks when virtual machines of the first tenants are about to access the exterior networks. The communication method, the communication system and the control node have the advantages that source address conversion flow in flow in the south-north directions only flows through the computational nodes instead of network nodes, accordingly, the problem of congestion of existing network nodes can be solved, and the performance of the integral networks can be improved.
Description
technical field [0001] The present invention relates to the technical field of cloud computing, and more specifically relates to a communication method, system and control node of a distributed network. Background technique [0002] Openstack is an open source cloud platform management project that can provide scalable and flexible cloud platform management. Since there are many tenants in Openstack, in order to ensure the security of each tenant, in the cloud data center of Openstack, different tenants need to be isolated, that is, different tenants cannot access each other. Under the same tenant, network traffic in Openstack can include east-west traffic, north-south traffic, and DHCP traffic. [0003] At present, in the legacy network model of Openstack, both east-west traffic and north-south traffic need to pass through network nodes, so it is easy to cause congestion of network nodes. In order to solve this problem, Openstack proposed a distributed virtual routing (Di...
