Problems solved by technology

That is, when the forwarding traffic of a VSI exceeds a certain value, the rate limit is imposed on all packets of the VSI. The main purpose of this method is to prevent VPLS packet forwarding from occupying too many system resources, but it cannot limit the rate for specific outgoing interfaces. , and this rate limiting method affects all VPLS packets in a VSI
Currently, there is no suitable way to limit the forwarding rate of VPLS traffic of all VSIs that use the specified interface as the outgoing interface without affecting the forwarding of VPLS packets on other outgoing interfaces.

Embodiment

[0030] see figure 1 The processing flow shown. The specific steps are:

[0031] Step 101, configure a VPLS traffic rate limiting policy on an interface that needs to perform VPLS traffic rate limiting.

[0032] According to different VPLS traffic statistics methods, configuring the VPLS traffic rate limit policy includes: 1. By setting the maximum value of VPLS forwarded traffic on the interface, determine the forwarding behavior of VPLS packets; 2. By setting the VPLS forwarded traffic on the interface to reach The set proportion of traffic sent by all services determines the forwarding behavior of VPLS packets. The above two rate limiting strategies are common statistical methods for network interface traffic, which are very simple and applicable.

[0033] The VPLS traffic speed limit policy can also specify the type of the restricted VPLS message. The type of message includes unicast, broadcast, unknown unicast, multicast, and the VPLS traffic rate limit policy can be us...

Abstract

The invention relates to a virtual special local area network service technology and discloses a service message flow speed-limiting method and device for a virtual special local area network. The technical scheme is that the method comprises a step (A) of setting whether to carry out a virtual private lan service (VPLS) flow speed-limiting strategy of an output interface for transmitting VPLS messages when a virtual exchange example transmits the VPLS messages during virtual exchange example configuration; a step (B) of carrying out a step (C) if the virtual exchange example carries out the VPLS flow speed-limiting strategy of the output interface for transmitting VPLS messages when the virtual exchange example transmits the VPLS messages, or else directly transmitting the VPLS messages and ending the flow; the step (C) of judging whether the VPLS message transmitting flow of the output interface for transmitting the VPLS messages meets the speed-limiting requirements of the VPLS flow speed-limiting strategy, discarding the VPLS messages if the VPLS message transmitting flow of the output interface for transmitting the VPLS messages meets the speed-limiting requirements, or else transmitting the VPLS messages. The service message flow speed-limiting method and device are used for virtual special local area network service message transmission, and band width resources can be utilized to the largest extent.

Description

technical field [0001] The invention relates to virtual private LAN service technology, in particular to a method and device for limiting speed according to outgoing interface traffic in a VPLS (Virtual Private LAN Service, virtual private local area network service) network. Background technique [0002] VPLS is a point-to-multipoint L2VPN service provided in public networks. This technology can effectively connect each access point, and realize point-to-point, point-to-multipoint, and multipoint-to-multipoint Ethernet services on the network topology. From the connection point of view, VPLS utilizes the IP / MPLS wide-area backbone network to provide users with a simulated LAN connection. From the point of view of service provision, the LAN simulated by VPLS provides convenient and flexible Ethernet services, and this simulated LAN connection is transparent to each user branch LAN across the WAN, and each branch LAN seems to be connected to on the same switch. Because VPL...
