Embodiment Construction

[0024] With the advancement of VCF technology, PEs can implement multi-homing access. Please refer to figure 1 , in the VCF, a PE belongs to two CBs, namely CB1 and CB2. The implementation of multi-homing has many advantages:

[0025] (1) Transfer the reliability of the IRF on the CB to the PE. For example figure 1 In this case, if CB1 fails, all PE traffic can be switched to CB2, and CB2 completes the forwarding of all data.

[0026] (2) The business data that needs to be forwarded on the PE is allocated to different CBs, and the forwarding business is evenly shared between the CBs; in this way, problems such as delay or packet loss caused by excessive load of a single CB can be avoided.

[0027] For point (2), this advantage is often difficult to realize. At present, many switching chips cannot support Higig (serial bus interconnection technology launched by Broadcom in the United States) port cross-chip aggregation, so it is impossible to aggregate multiple uplinks thro...

Abstract

The present invention provides a PE traffic scheduling method and device, which are applied to PE equipment in a VCF system. The method includes the following steps: creating Trunk a and Trunk b for the first switching chip, wherein Trunk a includes N Hash positions, and the N Hash positions are assigned to the ports of G1 and G2 respectively; Trunk b includes N Hash positions, and the N Hash positions are respectively assigned to the ports of G2; Identified as b; perform the same processing on the second switch chip; send the local forwarding entry of the PE uplink traffic to the first switch chip and the second switch chip, wherein the egress of the local forwarding entry is the uplink port of the switch chip ; Correspondingly reallocate at least one Hash position in the corresponding Trunk according to the change of the uplink state of the uplink port. Compared with the prior art, the present invention can more evenly share the uplink traffic to the uplinks of the two switching chips.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a flow scheduling method and device for PE equipment. Background technique [0002] With the expansion of the network scale, the number of network devices increases accordingly, and network management becomes a thorny issue in the management of data center infrastructure. On the other hand, modern big data centers also put forward higher requirements on the port density provided by the network to servers. For example, the scale of 10,000 servers is a common requirement in the reality of Internet data centers. As an effective means to increase the port density of access devices, the port expansion technology has gradually matured and been recognized by the industry. [0003] VCF vertical virtualization technology (Vertical Converged Framework, vertical convergence framework) is an implementation of this technology, which can meet the high-density access of data...
