Embodiment Construction

[0042] The virtual network management system and method in the cloud computing data center in the data center proposed by the present invention are described in detail as follows in conjunction with the accompanying drawings and embodiments.

[0043] Such as figure 2 As shown, the virtual network management system in the cloud computing data center according to an embodiment of the present invention includes: physical servers (three in this embodiment, but not limited thereto), and a controller. The system in this embodiment includes one controller, which is respectively connected to each server, and may also include more than one controller to control the physical servers separately.

[0044] The physical server is connected to the core switching network of the data center through the first network port, and the first network port has the identification of the physical server (for example, the MAC address and IP address of the port), so that the network packets sent by each ...

Abstract

The invention discloses a system and a method for managing a virtual network in a cloud computation data center, and relates to the technical field of network system structures and network communication protocols. The system comprises physical servers and a controller, the physical servers are connected with a core switching network of the data center, each physical server is provided with at least one switch supporting OpenFlow related protocols and is connected with the controller, and the controller builds the virtual network, maintains configuration of the virtual network and a mapping relation among the virtual network, a virtual broadcast domain and a local broadcast domain, and configures and controls the switches of the physical servers. By the aid of the system and the method, pressure on broadcasting and double-layer address tables and forwarding tables of the core switching network of the data center can be effectively reduced, large-scale management is facilitated, flows of different users can be effectively isolated, security is strengthened, and configuration of the virtual network of the data center can be quickly and flexibly changed along with dynamic distribution of virtual resources.

Description

technical field [0001] The invention relates to the technical field of network system structure and network communication protocol, in particular to a virtual network management system and method in a cloud computing data center. Background technique [0002] The data center is the provision center of various services on the Internet, mainly including three main components: computing, storage and network. The computing part is mainly responsible for processing data, the storage part is mainly responsible for storing and backing up data, and the network part is mainly responsible for connecting computing, storage and other resources and exchanging data. With the development of cloud computing, the scale of data centers is increasing day by day, and more and more enterprises move their services and businesses to data centers. In a data center that provides multi-tenancy services, in order to improve resource utilization, computing, storage, and network parts are often virtual...
