Problems solved by technology

[0003] However, since the size of a SID in SRv6 technology is 128 bits, the length of the encapsulated packet required to encapsulate a complete SID is very large. Obtaining a SID, the increase in the length of the encapsulated message and the number of decapsulation table lookups increases the pressure on the encapsulation and decapsulation of network devices, and at the same time leads to a decrease in network transmission efficiency

Abstract

The application proposes a data processing method, system, encapsulation node and decapsulation node, which relate to the field of communication transmission. The data processing method includes: obtaining at least two groups of data to be sent, wherein the data includes prefix data and suffix data; obtaining public prefix data of the prefix data; obtaining a local index according to the public prefix data, and Writing the local index and the public prefix data into a preset prefix table; writing the suffix data and the local index into a preset suffix table; writing the data in the prefix table and the data in the suffix table Writing the preset data encapsulation table and sending the data encapsulation table can realize the separate storage of public prefix data and a public prefix only needs to be stored once, so that this application can save a lot of table entry space and reduce the number of nodes storage pressure.

Description

technical field [0001] The embodiments of the present application relate to the field of communication transmission, and in particular to a data processing method, system, encapsulation node, and decapsulation node. Background technique [0002] The future network is oriented to the 5G era. In the face of 5G networks, network virtualization is the main development direction of the bearer network. The segment routing forwarding technology (Segment Routing IPv6, SRv6) based on Internet Protocol Version 6 (Internet Protocol Version 6, IPv6) is to adopt the existing IPv6 forwarding technology, and the routing segment in SRv6 directly uses the 128bit IPv6 address identifier, and Define some IPv6 addresses as instantiated SIDs (Segment IDs). Each SID has its own explicit role and function. Through different SID operations, simple network virtualization is realized. The traditional processing method of SID data is: apply for an index for each SID data, establish the SID encapsulat...
