Problems solved by technology

[0005] At present, some protocols can be used to advertise BIER-MPLS labels, but in actual network applications, changes such as the addition of BFR devices and configuration changes may change the range of BFR-id values ​​of devices on the original network, resulting in information changes
When the maximum value range of SI becomes larger, the device will allocate new BIER-MPLS labels for the increased value, and this operation may cause the forwarding of multicast data packets to be interrupted

Embodiment 1

[0021] Such as figure 1 As shown, the embodiment of the present invention provides a method for announcing a BIER-MPLS label, the method comprising:

[0022] S101, dividing multiple BIER-MPLS labels into at least 2 label intervals;

[0023] S102. Notify each label interval through a routing protocol.

[0024] In the embodiment of the present invention, multiple BIER-MPLS labels are divided into at least two label intervals, and each label interval is notified through a routing protocol, so that when the value range of SI becomes larger, the original BIER-MPLS On the premise of MPLS label announcement, the newly added BIER-MPLS label is advertised in the network, thus effectively solving the problem of multicast data packet forwarding interruption caused by the change of SI value range, so as not to affect the original BIER Packet forwarding.

[0025] The embodiment of the present invention is applied to BFR equipment (abbreviated as equipment), which includes BFIR and BFER....

Embodiment 2

[0071] An embodiment of the present invention provides a bit forwarding router device, the device includes a memory and a processor, the memory stores a computer program for advertising BIER-MPLS labels, and the processor executes the computer program to implement the The steps of any one of the methods in example one.

[0072] In the embodiment of the present invention, multiple BIER-MPLS labels are divided into at least two label intervals, and each label interval is notified through a routing protocol, so that when the value range of SI becomes larger, the original BIER-MPLS On the premise of MPLS label announcement, the newly added BIER-MPLS label is advertised in the network, thus effectively solving the problem of multicast data packet forwarding interruption caused by the change of SI value range, so as not to affect the original BIER Packet forwarding.

[0073] In detail, the processor executes the computer program to achieve the following steps:

[0074] Divide mult...

Embodiment 3

[0090] An embodiment of the present invention provides a computer-readable storage medium, the storage medium stores a computer program, and when the computer program is executed by at least one processor, the steps of the method described in any one of the first embodiment are implemented.

[0091] The computer-readable storage medium in the embodiment of the present invention may be RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, register, hard disk, removable hard disk, CD-ROM or any other form of storage medium known in the art. A storage medium may be coupled to the processor such that the processor can read information from, and write information to, the storage medium, or it may be an integral part of the processor. The processor and storage medium may be located in an application specific integrated circuit.

[0092] Certainly, when the embodiment of the present invention is actually implemented, reference may be made to Embodiment 1 and Embodiment 2...

Abstract

The invention discloses a method, device and storage medium for announcing BIER-MPLS labels, which are used to solve the problem of interruption of multicast data message forwarding caused by the change of SI value range. The method includes: dividing a plurality of BIER‑MPLS labels into at least two label intervals; and notifying each label interval through a routing protocol. The invention effectively solves the problem of interruption of forwarding of multicast data message caused by the change of SI value range, thereby not affecting original BIER message forwarding.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method, device and storage medium for announcing BIER-MPLS labels. Background technique [0002] BIER (Bit Index Explicit Replication, Bit Index Explicit Replication) is a technology for forwarding multicast data packets in the network. A device supporting BIER on the network is called a BFR (Bit-Forwarding Router, bit-forwarding router), and the BFR constitutes a BIER domain on the network. The edge device where the multicast data message enters the BIER domain is called BFIR (Bit-Forwarding Ingress Router, bit-forwarding ingress router), and the destination device for multicast message forwarding is called BFER (Bit-Forwarding Egress Router, bit forwarding egress router). There may be one or more sub-domains (sub-domains) in the BIER domain, and the BFIR device and the BFER device will assign a unique BFR-id in each sub-domain to identify the BFR device. [0003] When t...
