The working principle of the apparatus for implementing a high-speed network in a cloud computing system according to the embodiment of the present invention will be described below with reference to a specific application example.
As shown in fig. 1, each computing node in the cloud computing system carries a virtual host of a user, and the smart switch and the gateway node are responsible for providing network services for the virtual host in the computing node. Network data entering and exiting from a computing node in the system are mainly divided into two types, one type is east-west network flow, and the flow does not need to pass through a flow gateway and comprises flow which does not need to be routed between the same networks (flow which does not need to pass through a virtual bridge of an intelligent switch and a virtual router) and flow which needs to be routed between different networks (flow which needs to pass through the virtual bridge and the virtual router of the intelligent switch and the virtual router). The other type is the south-north network traffic, which is mainly generated by the virtual host accessing the extranet or the extranet accessing the virtual host, and the south-north network traffic needs to pass through the gateway node besides the intelligent switch.

In the embodiment of the invention, a strategy of splitting a traditional network node into an intelligent switch and a gateway node is provided, and the flow in the cloud computing system is processed in a differentiated mode, so that the network processing performance of the cloud computing system is improved.
When the network flow of the virtual host flows into the intelligent switch from the flow of the computing node, the intelligent switch selects different forwarding strategies by judging the destination address of the network flow. If the destination is the address of the same network, directly forwarding the flow to the computing node where the destination address is located through the virtual network bridge; if the destination is the address of different networks, the flow can be routed through the virtual router, if the destination network is under the virtual router, the flow is forwarded to the virtual bridge after being routed by the virtual router, the virtual bridge is forwarded to the computing node where the destination address is located, if the destination address is not under the virtual router, the flow is lost to the gateway node, the gateway node can select the corresponding gateway, and the gateway processes the flow and forwards the flow to the external network.
When the external network flow accesses the virtual host, firstly, a proper gateway is found through the gateway node, the gateway processes the flow and then forwards the flow to a corresponding virtual router in the intelligent switch, the virtual router searches a routing table according to the destination address of the flow and then forwards the routing table to a corresponding virtual bridge, and the virtual bridge forwards the flow to a computing node where the destination address is located.

When the destination computing node and the source computing node corresponding to the destination address belong to different networks, the first network flow is forwarded to the corresponding virtual network bridge after being routed through the virtual router, and the first network flow is forwarded to the destination computing node through the virtual network bridge. And when the destination address is an external network address, forwarding the first network flow to the gateway node, so that the gateway node selects a corresponding gateway according to the destination address of the first network flow to perform flow processing on the first network flow and then forwards the first network flow to the external network corresponding to the destination address. Therefore, the circulation of network traffic in the east-west direction in the cloud computing system and the circulation of network traffic in the north-south direction in the cloud computing system accessing the external network are completed.
Specifically, in an embodiment, the method for implementing a high-speed network in a cloud computing system further includes:
step S103: and receiving second network traffic forwarded by the gateway node, wherein the second network traffic is the network traffic which is obtained after second network traffic for accessing the virtual host and sent by the external network is obtained, and selecting a corresponding gateway according to a destination address of the second network traffic to process the second network traffic. Specifically, the second network traffic is network traffic for an external network to access a virtual host carried by a certain computing node in the cloud computing system, and a destination address of the second network traffic is a network address of the virtual host to be accessed to a corresponding computing node. The second network flow is firstly sent to the gateway node by the external network, and then the gateway node selects a corresponding gateway according to the destination address and forwards the gateway to a corresponding virtual router in the intelligent switch.
Step S104: and routing according to the destination address of the second network flow, forwarding to the corresponding virtual bridge, and forwarding the second network flow to the computing node corresponding to the virtual host to be accessed through the virtual bridge. Specifically, after receiving the second network traffic, the virtual router in the intelligent switch searches a routing table according to a destination address of the second network traffic, forwards the second network traffic to the corresponding virtual bridge according to the routing table, and forwards the second network traffic to the computing node corresponding to the virtual host to be accessed by the external network through the virtual bridge, thereby completing the circulation of the network traffic in the north-south direction when the external network of the cloud computing system accesses the cloud computing system.
