Embodiment Construction

[0029] The main embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] figure 1 is a schematic flowchart of a method for automatically segmenting a network provided by an embodiment of the present invention, as shown in figure 1 As shown, the method steps include:

[0031] Step S101: Obtain the maximum network scale supported by the BIER-TE network.

[0032] In one implementation manner, the BIER-TE controller obtains the maximum network scale specified by the upper layer through the northbound interface, that is, the maxBSL value (maximum BSL).

[0033] In another implementation manner, the BIER-TE controller acquires the maximum network scale negotiated between BIER-TE network nodes through the southbound interface, that is, the maxBSL value (maximum BSL).

[0034] Step S102: According to the topology information of the BIER-TE network, determine the total network scale of the BIER network.

Abstract

The invention discloses a method, device, device and storage medium for automatically segmenting a network, and relates to the technical field of network communication. The method includes: obtaining the maximum network scale supported by a traffic engineering-based bit index display copy BIER‑TE network; According to the topology information of the BIER-TE network, determine the total network scale of the BIER network; according to the total network scale and the maximum network scale, determine whether the BIER-TE network satisfies the network segmentation condition; if the If the BIER-TE network satisfies the network segmentation conditions, then the BIER-TE network is segmented. In the embodiment of the present invention, by segmenting the BIER-TE network, the total network scale of each subnet obtained by segmentation is not greater than the maximum network scale, ensuring that the message can be forwarded to the egress node of the network.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method, device, equipment and storage medium for automatic network segmentation. Background technique [0002] BIER-TE (Bit Index Explicit Replication Traffic Engineering, BIER-TE, Bit Index Explicit Replication Based on Traffic Engineering) forwarding architecture, introduces BIER-TE controller layer on the basis of BIER, and sends the forwarding table through the controller, At the same time, the path algorithm is used to calculate the optimal path, and packets are forwarded in an explicit hop-by-hop manner. It overcomes the disadvantages that the BIER message forwarding path is not optimal and it is difficult to adapt to the path update caused by topology changes, and at the same time makes the network flow control more flexible. [0003] In a multicast scenario, when multicast traffic is transmitted on a BIER-TE network, a specific BIER header needs t...
