Problems solved by technology

[0004] With the development of the data center, the amount of data in the data center is also increasing, and the effective management and control of data traffic is becoming more and more important for the data center, and the broadcast, unknown unicast and multicast (broadcast, unknown destination Address, multicast, abbreviation: BUM) traffic copying and forwarding will occupy a lot of bandwidth, unnecessary copying and forwarding of BUM traffic will cause a lot of bandwidth to be wasted

Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] A data center can be considered as a data center architecture in which multi-tenants share computing, storage, and network resources. After computing resources are virtualized, the network needs to provide a larger layer-2 domain. Virtual Extensible LAN (VXLAN) technology provides a logical layer-2 network on the basis of traditional networks, adapting to the flexible migration of VMs and resource integration, and realizing Decoupli...

Abstract

The invention discloses a data flow control method, a controller and a data center system. The method of the present invention includes: the controller receives an offline notification message sent by the virtual machine management platform, and the offline notification message is used to notify that the first virtual machine has gone offline; if it is determined that the virtual local area network where the first virtual machine is located does not If any virtual machine is online, the controller instructs all top-of-rack switches configured with the virtual local area network to stop forwarding BUM traffic to the virtual local area network. The invention can realize the management and control of BUM flow forwarding, reduce unnecessary waste of bandwidth, and realize the flow optimization of the data center.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data flow control method, a controller and a data center system. Background technique [0002] The data center is used to accelerate the transmission of information on the Internet infrastructure. In order to adapt to the growth of business volume and reduce maintenance costs, the data center gradually migrates to large-scale two-tier technology and virtualization. [0003] Data center virtualization technology mainly includes three aspects: network virtualization, storage virtualization and server virtualization. Server virtualization technology can decouple the operating system and application programs inside the server from the underlying hardware. Through dedicated virtualization software management, one physical server can virtualize multiple virtual machines (virtual machines, VMs), thus enabling multiple It also enables virtual machines to be migrated from...
