Network establishment method and system, and network control center

Abstract

The invention provides a network establishment method and a system, and a network control center. The method comprises the following steps of receiving configuration information used for establishing a logic network; according to the configuration information, after corresponding processing is performed, calling an assigned interface of the network control center to carry out establishment processing of the logic network. Through the method, the system and the network control center of the invention, the private and isolated logic network is established for different users; according to distribution of calculating resources owned by the user, network partition and connection are completed; network configuration is uniformly performed and strategy execution is controlled; a QOS demand needed by the user is satisfied and flexible expansion can be performed according to a need.

Description

technical field [0001] The invention relates to the fields of data center, virtual data center, enterprise network and the like, in particular to a method and system for creating a network and a network control center. Background technique [0002] In recent years, as the scale of data centers continues to expand, the complexity of deploying and maintaining large-scale data center networks has risen sharply; with the development of cloud computing technology and its application in data centers, the organization and operation structure of traditional networks has been unable to Support the dynamic and flexible on-demand allocation and deployment service methods required by cloud computing resources: the network needs to sense the various needs of upper-layer virtual machines, and virtual machines may be migrated due to load balancing or high availability requirements, which may be due to green energy saving It needs to be closed or started in a planned way according to busine...

[0002] In recent years, as the scale of data centers continues to expand, the complexity of deploying and maintaining large-scale data center networks has risen sharply; with the development of cloud computing technology and its application in data centers, the organization and operation structure of traditional networks has been unable to Support the dynamic and flexible on-demand allocation and deployment service methods required by cloud computing resources: the network needs to sense the various needs of upper-layer virtual machines, and virtual machines may be migrated due to load balancing or high availability requirements, which may be due to green energy saving Need to shut down or start up in a planned way according to business changes

Regardless of whether the virtual machine is loaded on any physical machine to run, its IP (Internet Protocol, protocol for interconnection between networks) and MAC (Media Access Control, media access control) addresses and corresponding ACL (Access Control List, access control list) Network control strategies need to remain unchanged; IAAS (Infrastructure as a Service, Infrastructure as a Service) operators regard the network as a differentiated competitive advantage for their business, and data center owners hope that the cost of network customization will be low and the failure convergence time will be reduced. Low level; there are tens of thousands of tenants, and the simple isolation method of the existing VLAN (Virtual Local Area Network, virtual local area network) cannot meet the needs. Tenants hope to configure the network characteristics of their own virtual private clouds to meet the required QOS (Quality of Service, service quality) requirements
