Embodiment Construction

[0050] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples.

[0051] The flow chart of this embodiment is as follows figure 1 and figure 2 As shown, the technical scheme is as follows:

[0052] In step S1, in this example, two Dell R820 servers are used to build the Openstack platform, including a control node and a computing node, and the virtual link is built based on Openvswitch. hardware architecture such as image 3 As shown, the control node is connected to the management network, the tunnel network, and the external network, and its corresponding management network IP is 192.168.1.11; the tunnel network IP is 10.0.1.11. The computing nodes are connected to the management network and the tunnel network, and the corresponding management network IP is 192.168.1.31; the tunnel network IP is 10.0.1.31.

[0053] In step S2, build as Figure 5 Typical virtual network topology shown, wh...

Abstract

The invention provides a high-performance route forwarding method in cloud computing, relating to the field of network simulation. To solve a performance problem of cross-subnet data communication ina virtual network in a current Openstack host machine, the invention provides an SDN-based route control platform, a route table in a virtual network topology is mapped to a flow table in real time bybuilding a route decision layer and a data forwarding layer, consequently, forwarding of three layers of network data is controlled by a virtual route topology in the route decision layer, but an Openflow switch directly forwards a data packet. Further, a virtual network topology monitor module is designed to monitor route hop count of nodes in real time, guaranteeing forwarding fidelity of threelayers of network data packets and improving the performance of the virtual network. Creation of a typical network topological scene proves that the method is effective.

Description

Technical field: [0001] The invention relates to the field of network simulation, in particular to a high-performance routing and forwarding method in cloud computing. Background technique: [0002] The Internet has developed rapidly in the past few decades, and cloud computing has become a very important service method. More and more people and enterprises obtain the required IT resources through the Internet in a self-service manner. Facing the increasing user demands, the performance of network virtualization in cloud computing has been challenged even more. [0003] As the representative of open source cloud computing, Openstack has certain performance problems in its virtual network. For example, the east-west data traffic between cloud hosts across network segments within the host needs to be forwarded through the routing function of the network node. Its data forwarding performance is limited by inter-cluster hardware devices, and it also causes problems such as exc...
