Cloud data center heterogeneous network interconnection system and method

Abstract

The invention discloses a cloud data center heterogeneous network interconnection system and method, and belongs to the technical field of computer networks. The cloud data center heterogeneous network interconnection system provided by the invention comprises a VmWare platform, Openstack platform, The system comprises an SDN controller, a cloud platform and an agent node, one side of the agent node is connected with a VmWare platform, the other side of the agent node is connected with an Openstack platform, and the SDN controller takes over the agent node and the Openstack platform and issuesa flow forwarding flow table to the agent node and the Openstack platform. The cloud data center heterogeneous network interconnection system can dynamically configure the large-scale network isolation capability and the flexible large two-layer network architecture, solves the interconnection and intercommunication problems of different network types, and has very good popularization and application values.

Description

technical field [0001] The invention relates to the technical field of computer networks, and specifically provides a cloud data center heterogeneous network interconnection system and method. Background technique [0002] The core of cloud computing is the virtualization of computing capabilities. Through virtualization, the computing capabilities scattered in various physical servers are integrated together to provide services to all users in the form of a unified resource pool. The virtualization of computing power drives the virtualization of other resources in the data center. The objects to be connected to the network of the data center have evolved from relatively fixed servers and storage to constantly changing virtual machines and storage devices. This brings new challenges to traditional network technologies. [0003] The traditional data center network architecture is similar to an ordinary campus network, consisting of two layers + three layers. The second layer...

Problems solved by technology

[0004] 1. The specification of network device entries reaches the upper limit, and the number of MAC addresses of virtual machines increases exponentially, which puts enormous pressure on the network devices on the access side. Once the network device entries on the access side reach the maximum specification, new MAC addresses will no longer be learned. address, or frequently refresh the MAC table, resulting in network instability or even unavailability;

[0005] 2. In a data center with a large number of tenants, the isolation of VLAN technology brings scalability problems. Due to the limited number of VLANs, it cannot meet the needs of a large-scale cloud service platform;

When the server scale reaches tens of thousands or tens of thousands of servers, any pure large-scale two-tier technology can no longer fully meet the needs of large-scale expansion, and requires a wider range of technological innovations to eliminate these limitations and meet cloud computing requirements.
