Problems solved by technology

[0004] In the MPLS network where the long-delay satellite link is used as the backup communication, when the network fluctuates, because the route of the interior gateway protocol IGP changes frequently, the FEC-label mapping pair needs to be deleted and created repeatedly, consuming system CPU resources , the MPLS forwarding path will be disconnected repeatedly, resulting in long-term traffic interruption

Abstract

The invention relates to a satellite long-delay high-efficiency MPLS network route oscillation processing device, which comprises a route sensing unit, a message transmit-receive unit and a state recording unit. The route sensing unit is used for carrying out route optimum selection and judging whether an MPLS network has a route deleting or adding event; the message transmit-receive unit is used for receiving and sending an MPLS control message and is interacted with routing neighbors on the network; and the state recording unit is used for recording FEC state, and carrying out state update according to the route event sensed by the route sensing unit. The route sensing unit is communicated with the message transmit-receive unit; the message transmit-receive unit is communicated with the state recording unit; and the state recording unit is communicated with the route sensing unit. The device and method improve MPLS label switch path stability and availability under a satellite long-delay environment, especially under a large-scale routing environment.

Description

technical field [0001] The invention relates to the technical field of network routing oscillations, in particular to a method and device for efficiently processing MPLS network routing oscillations with long satellite delays. Background technique [0002] MPLS Multi-Protocol Label Switching (Multi-Protocol Label Switching, MPLS) is a new generation IP high-speed backbone network switching standard, which uses labels to forward data. When a packet enters the network, a fixed-length short label should be assigned to it, and the label and the packet should be encapsulated together. During the entire forwarding process, the switching node forwards only according to the label. In a multi-protocol label switching MPLS network, data transmission occurs on a label switched path (Label Switched Path, LSP). The label distribution path LDP (Label Distribution Protocol) defined by RFC5036 is a widely deployed MPLS control signaling protocol, which is used to exchange labels between MP...
