Embodiment Construction

[0027] In order to further illustrate the technical means and functions adopted by the present invention to achieve the intended invention purpose, further detailed description will be given below in conjunction with the accompanying drawings and preferred embodiments.

[0028] Such as Figure 1 to Figure 4 , the present invention proposes a label-based method for rerouting monitoring information of planting Chinese herbal medicines, comprising the following steps:

[0029] S1: Embed packet labels containing precomputed routing paths and alternate next hops into incoming packets to speed up data plane updates

[0030] S2: During the forwarding process of the data packet in the normal routing path, if it is confirmed that there is a router interruption, the first router in the routing path will execute the rerouting method to infer the data packet affected by the interruption and plan a new path for it, and finally Packets affected by the outage are rerouted through the planne...

Abstract

A label-based method for rerouting Chinese medicinal material planting monitoring information, comprising the following steps: S1: embedding a data packet label including a pre-calculated routing path and a backup next hop into an incoming data packet; S2: the data packet is routed In the process of forwarding in the path, if it is confirmed that there is a router interruption, the first routing node in the routing path will perform the rerouting method to infer the packets affected by the interruption and plan a new path for it, and finally re-route through the planned new path. Route packets affected by the outage. With the above technical solutions, the present invention accelerates rerouting through data packet labels, embeds data plane labels into each incoming data packet, and implements rerouting through a two-stage forwarding table, so that each route of the medicinal material planting base is implemented. If the routing and forwarding interruption failure occurs, the monitoring point can quickly forward the required data packets through the newly established routing path.

Description

technical field [0001] The invention belongs to the technical field of network communication, in particular to a label-based rerouting method. Background technique [0002] With the continuous improvement of the national level, the concept of health has gradually become popular among the people, the people's demand for health has become urgent, and the demand for traditional Chinese medicinal materials has increased day by day, which has promoted the vigorous development of the Chinese medicinal material planting industry. Large-scale planting of Chinese medicinal materials requires the establishment of multiple network monitoring points to continuously obtain the growth status of various medicinal materials, and timely summarize and feed back the information to technical personnel for rationalized and optimized planting. Therefore, the connectivity of each monitoring node in this monitoring network is the guarantee of the accuracy of our information. According to surveys, ...
