vlan automatic scheduling method and device

Abstract

The invention relates to a VLAN automatic scheduling method and device. The method comprises steps: S1, the basic business configuration information of two switches uplinked with each OLT, the peak bandwidth utilization rates of the two switches and the business data of active users on uplink routing equipment are acquired; S2, whether the OLT needs balanced adjustment is judged; S3, as for an OLTwhich is judged to require balanced adjustment, a VLAN scheduling direction of the OLT is determined, and the bandwidth of each VLAN and the bandwidth of each VLAN combination under a switch which isabout to be transferred out of the VLAN are determined; and S4, a VLAN or a VLAN combination with the minimum absolute difference in absolute differences between the bandwidth of each VLAN and each VLAN combination under a switch which is about to be transferred out of the VLAN uplinked with each OLT in need of balanced adjustment and the two-uplink bandwidth difference corresponding to the OLT is determined, and the VLAN or the VLAN combination with the minimum absolute difference is transferred to a switch which is about to be transferred to the VLAN uplinked with the OLT. Thus, through scientific calculation, the effectiveness and the accuracy of business balanced adjustment are improved.

Description

technical field [0001] The invention relates to the technical field of GPON networks, in particular to a VLAN automatic scheduling method and device. Background technique [0002] Since the hot backup technology is not yet mature enough in the application of OLT (that is, optical line terminal) dual uplink GPON (that is, passive optical network technology), to achieve service balance under the GPON service cold backup technology, on the one hand, data service production is required. The personnel adjust the service planning and access according to the number of Vlans (virtual local area networks) carried by the OLT dual uplinks respectively. Adjust the balance of OLT dual uplink links by artificially switching Vlans, thereby reducing link congestion caused by excessive load on one side. [0003] Aiming at the balance adjustment problem of OLT dual uplink links, the method in the prior art to ensure link balance from a rough service access plan is too simple, and it is diffi...

Problems solved by technology

[0003] Aiming at the balance adjustment problem of OLT dual uplink links, the method in the prior art to ensure link balance from a rough service access plan is too simple, and it is difficult to truly ensure service balance, because each Vlan carries the number of users in the later stage. How much is development and change

Moreover, the manual cutover adjustment of service Vlans by maintenance personnel is basically carried out after link congestion occurs, and it is necessary to adjust which Vlans to be cutover and how many Vlans to be cutover. Only with multiple adjustment attempts can a relatively balanced state be achieved, which will lead to a huge amount of cutover work, and the cutover work at the same point will often be repeated several times. The phenomenon that the side link load is too high may also easily cause the peak bandwidth utilization rate of the link from the SW (that is, the switch) device to its uplink routing device BRAS to exceed the threshold of 70%, resulting in link congestion.

[0004] The reason is that the balance adjustment of the GPON cold standby business in the existing technology cannot achieve the effect of scientific balance at all, mainly because it does not fundamentally guarantee the balance of business load from scientific data calculation and automatic balance adjustment. The dynamic balance adjustment based on Vlan scheduling cannot be realized, so the efficiency and accuracy of business balance adjustment cannot be guaranteed
