Embodiment Construction
[0064] In order to make the purposes, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments These are some, but not all, embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.
[0065] like figure 1 As shown, it is a schematic diagram of an application scenario of an embodiment of the present disclosure. Wherein, device A and device B belong to the same DRNI system, and an LDP neighbor relationship is established between device A and device B. Device A and device B assign labels to device D respectively. For example, th...

The present disclosure relates to the field of network communication technology, and specifically relates to a method for establishing a label forwarding table and a method for message forwarding based on a distributed aggregation system, wherein the method for establishing a label forwarding table includes obtaining a local first label forwarding table; wherein, the first A label forwarding table is used to represent the mapping relationship between the next hop node and the label; obtain the incoming label allocated by the peer end for the next hop node; wherein, the peer end and the local belong to the same distributed aggregation system; from the first label forwarding table Extract the outgoing label locally assigned to the next hop node; establish a second label forwarding table based on the incoming label and the outgoing label. By obtaining the inbound label allocated by the peer end for the next hop node, that is, the inbound label allocated by the peer end for the next hop node is stored locally. When the locally obtained packet carries the inbound label, the local The incoming label can be found in the forwarding table to realize the normal forwarding of the message, thereby solving the problem that the label forwarding is incompatible with the DRNI network.
Description
technical field [0001] The present disclosure relates to the technical field of network communication, and in particular, to a method for establishing a label forwarding table based on a distributed aggregation system and a method for forwarding messages. Background technique [0002] In the process of data packet transmission, in order to ensure the normal forwarding of data packets, that is, when a certain network device fails, the data packets can be quickly switched to another network device for forwarding, usually a distributed elastic network is used. Interconnection (Distributed Resilient Network Interconnect, hereinafter referred to as DRNI) constructs a network system. DRNI is a cross-device link aggregation technology, which implements cross-device link aggregation by combining two physical devices with one device at the virtual layer at the aggregation level, thereby providing device-level redundancy protection and traffic load sharing. [0003] figure 1 The DRN...
