Bandwidth adjusting method and device in network virtualization system

Abstract

The embodiment of the invention provides a bandwidth adjusting method in a network virtualization system. The network virtualization system comprises a center module and m far-end modules, and the m far-end modules are connected with a physical interface of the center module through n PWs. The bandwidth adjusting method comprises the steps that real-time bandwidths of the n PWs are acquired from the m far-end modules; when the sum of the acquired real-time bandwidths of the n PWs is larger than the bandwidth of the physical interface, the configuration bandwidths of P PWs are adjusted; the adjusted configuration bandwidth values of the P PWs are sent to the far-end modules which are connected with the P PWs respectively. The embodiment of the invention further provides a bandwidth adjusting device. According to the technical scheme, when the sum of the real-time bandwidths of the n PWs is larger than the bandwidth of the physical interface of the center module, the configuration bandwidth of the far-end module PW is adjusted, and the problems of network congestion and packet loss of the center module are solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for bandwidth adjustment in a network virtualization system. Background technique [0002] Quality of Service (English full name is Quality of Service, English abbreviation is Qos) technology is a technology for network equipment to guarantee the quality of forwarded user data. It is mainly measured by indicators such as bandwidth, delay, and packet loss rate. For Internet Protocol (English full name is Internet Protocol, English abbreviation is IP) network, since packets are processed by best-effort forwarding, if there is no QoS mechanism, some service types (such as video, voice, etc.) may not be accepted due to Timely forwarding results in service quality that cannot meet the requirements. Therefore, the QoS capability of network equipment is a very important measurement standard. Network devices support QoS mainly throu...
