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 invention provides a PE traffic scheduling method and device which are applied to PE equipment of a VCF system. The method comprises the following steps that a Trunk a and a Trunk b are established for a first exchange chip, wherein the Trunk a comprises N Hash positions, and the N Hash positions are allocated to a port of G1 and a port of G2 respectively; the Trunk b comprises N Hash positions, and the N Hash positions are respectively allocated to the port of G2; the Trunk in the port of the G1 is marked as a, and the Trunk in the port of G2 is marked as b; a second exchange chip is processed in the same way; local forwarding items of uplink traffic on PE are issued to the first exchange chip and the second exchange chip, wherein outlets of the local forwarding items are uplink ports of the exchange chips; at least one Hash position in the corresponding Trunk is allocated again according to variation of the uplink state of an uplink port correspondingly. Compared with the prior art, uplink traffic can be more evenly distributed to all the uplinks of the two exchange chips.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a PE traffic scheduling method and device. 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 center virtual...
