Problems solved by technology

In the above situation, due to the data transmission between the Master device and the Slave device, the forwarding pressure on the stack port will be increased when the above situation occurs, which may cause traffic congestion and affect normal service traffic forwarding
[0007] Therefore, in an IRF networking environment, unnecessary cross-device forwarding of data (such as cross-Master and Slave devices) should be avoided to reduce the forwarding pressure on the stack port; however, if image 3 As shown, when the outbound interfaces of the main link and the backup link of FRR are on the Master device and the Slave device respectively, data forwarding across devices will inevitably occur, and there is no method to solve the above problems in the prior art , which cannot solve the problem of traffic congestion and affect normal business traffic forwarding

Embodiment Construction

[0037] In the prior art, the reason for cross-device traffic is that the outbound interfaces of the primary link and the backup link in the FRR route are located on different devices in the IRF system. Therefore, when calculating or specifying to form an FRR route, the primary link Judging with the outgoing interface of the backup link, when the outgoing interface of the main link and the outgoing interface of the backup link are located on the same member device, an existing FRR route is formed on the member device, and this process will not be repeated in the present invention . Subsequent processing is for the outbound interface of the primary link and the outbound interface of the backup link to be located on different member devices.

[0038] Based on this situation, the present invention proposes a data transmission method based on FRR in an IRF system. The IRF system includes multiple member devices (with a Master device and at least one Slave device), and there is a fo...

Abstract

The invention discloses an FRR (Fast ReRoute) based data transmission method and a device in IRF (Intelligent Resilient Framework) system. The method comprises the following steps that: when a member device needs to send data to a target device, the member device queries output interface information in a route of the target device; and when the route of the target device comprises an output interface of the member device, the member device sends the data to the target device through the route comprising the output interface of the member device. In the invention, the problem of cross-device data forwarding can be effectively avoided, and thus the situation that the normal business is affected by the congestion of a stack port is avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and equipment based on FRR in an IRF system. Background technique [0002] IRF (Intelligent Resilient Framework) is a software virtualization technology. Multiple devices are connected together through IRF physical ports. After necessary configuration, they are virtualized into a distributed device. This technology mainly has the following advantages: ( 1) Simplified management. After the IRF is formed, users can log in to the IRF system through any port of any member device, and manage all member devices in the IRF in a unified manner; (2) High reliability. The IRF is composed of multiple member devices. The master) device is responsible for the operation, management and maintenance of the IRF, and the slave (slave) device can also process business while serving as a backup. Once the master device fails, a new master device can be quickl...
