Embodiment Construction

[0024] Such as figure 1 Shown, the concrete implementation process of the present invention is as follows:

[0025] (1) Computing nodes create 3 bridges

[0026] #ovs-vsctl add-br br-int

[0027] #ovs-vsctl add-br br-ex

[0028] #ovs-vsctl add-br br-phy

[0029] #ovs-vsctl add-port br-phy eth1; ovs-vsctl add-port br-ex ext2

[0030] (2) Create a dhcp network space for the network

[0031] #ip netns add dhcp-net1

[0032] #ovs-vsctl add-port br-int tap9tag Taiwan 9 --set interface tap9type Taiwan internal

[0033] #ip netns exec dhcp-net1ip addr add 192.168.12.1 / 24dev tap9

[0034] #ip netns exec dhcp-net1ifconfig tap9promisc up

[0035] Then start the dhcp service on dhcp-net1

[0036] Create a routing network space for each user and set the gateway

[0037] #ip netns add qr-123456

[0038] #ovs-vsctl add-port br-int gw_tag9tag taiwan 9 --set interface gw_tag9type taiwan internal

[0039] #ip netns exec qr-123456 ip addr add 192.168.12.254dev gw_tag9

[0040] #ip ...

Abstract

The invention relates to the technical field of cloud computing, in particular to a method for implementing a distributed router suitable for cloud computing. The steps of the present invention are as follows: 1, each calculation node creates three network bridges; 2, the calculation node creates an isolated virtual network space for each network, and adds a network interface to connect to the internal network bridge, and starts in the virtual network space dhcp service. 3. Each computing node creates a new network space for multiple networks of the same tenant that need to communicate, named it a routing network space, and adds a network port to the routing network space for each network as a gateway; The gateway is set to the same mac and ip. 4. When creating a virtual machine, update the arp table of the routing network space accordingly and connect to the internal bridge. 5. Set flow rules on the internal bridge and intranet bridge. The invention solves the problem of single-point failure and large load of virtual machine network; it can be used for realization of distributed router of cloud computing.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method for implementing a distributed router suitable for cloud computing. Background technique [0002] Under the cloud platform, each user hopes that he can create a network at will, and the user hopes to control the communication of different networks. [0003] The usual solution in the industry is to set a high-performance computer as the network control node. Then the network control node has the following functions: 1) the network control node sets the ip of the virtual machine through dhcp; 2) the gateway of each network is set at the network control node; 3) each network performs NAT mapping at the network control node. [0004] However, the usual solutions in the industry have the following disadvantages: [0005] 1. A single point of failure will affect the communication of all virtual machines. If a hardware failure occurs on a network node, the virtual mac...
