Embodiment Construction

[0062] Figure 4 As shown, device A and device B are forwarded through the IRF system, and device A and device B respectively establish a connection with each IRF member device, and each link forms an aggregation. All data that reaches device B via device A can implement load sharing and link backup on IRF member devices. But when the link between IRF member device IRF1 and device B is disconnected, the data forwarded by device A to IRF will be forwarded to IRF2 through the IRF link between IRF1 and IRF2, and forwarded to device B on IRF2. This ensures the forwarding of traffic.

[0063] However, the link between IRF2 and device B will have traffic forwarded through IRF1 and traffic forwarded through IRF2 at the same time; when the sum of the two data flows is greater than the link bandwidth between IRF2 and device B, the Packet loss due to congestion. At the same time, the traffic passing through the IRF link between IRF1 and IRF2 will consume the link bandwidth and increa...

Abstract

The invention discloses a network equipment and a forwarded information updating method. The application is used in upper link equipment connected to a stacking system, and the upper link equipment can update a forward information base locally saved according to the failure of a down link chain of member equipment of the stacking system, so that a message forwarding path selecting scheme in the existing converged network is optimized. When the down link chain has failure, load sharing can be better carried out for flow in the member equipment of the stacking system, the forwarding load of a converged link is reduced, the link congestion of the member equipment is avoided, and the reliability of the link is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network device and a method for updating forwarding information thereof. Background technique [0002] IRF (Intelligent Resilient Framework, Intelligent Resilient Framework) is a stacking technology. Its core idea is to connect multiple devices together through IRF ports, and after necessary configuration, virtualize them into a "distributed device". Using this virtualization technology can integrate the hardware resources and software processing capabilities of multiple devices to achieve collaborative work, unified management and uninterrupted maintenance of multiple devices. Such as figure 1 As shown in FIG. 2 , it is a schematic diagram of a typical IRF networking structure in the prior art. [0003] In a typical IRF network, there are two types of devices, IRF member devices and stand-alone devices. in: [0004] The stand-alone device can only run on a single m...
