Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be further described in detail below in conjunction with specific embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.

[0040] The inventor of the present application proposes that since the physical bandwidth of the P port is limited, a concept of bandwidth weight value is proposed for the virtualized switch port inside the virtualized switch, so that the bandwidth of the port is allocated according to the proportion of the weighted value. When the switch is in the congested state for externally forwarding data, each port cannot send packets freely, and the external forwarding bandwidth capability depends on the configured weight value; when the externally forwarding data of the switch i...

Abstract

The invention relating to the virtualized switch technology discloses a method and device for realizing the network bandwidth priority in a virtualized switch. The method comprises the following stepsthat: when a virtualized switch forwards a data packet externally and the virtualized switch is determined to be in a congestion state, available bandwidths of physical ports are allocated for all virtual ports allocated based on priority bandwidths in the virtualized switch according to proportions of preset bandwidth weight values of all virtual ports to the sum of bandwidth weight values of all virtual ports and thus data forwarding is carried out.

Description

technical field [0001] The invention relates to a virtualized switch technology, in particular to a method and device for realizing network bandwidth priority in a virtualized switch. Background technique [0002] At present, the bandwidth priority control function of the virtual switch is becoming more and more prominent. The virtual network card of the virtual machine is connected to the virtual switch, such as figure 1 shown. Among them, 1-N are all ports used to connect to virtual network cards, and P is a physical network card for external data forwarding. When the 1-N port participates in sending out packets, it needs to be forwarded through the P port. The 1-N ports participating in the packet sending are all equal, and when the outgoing data packets pass through the P exit, the forwarding probability is equal. [0003] In view of the above problems, a port bandwidth prioritization technology is proposed in the related art, which is accomplished through a rate limi...
