Research And Implementation Of Intent Subsystem In Intent-driven Intelligent Routing System

With the rapid development of the Internet,the network structure has become increasingly complex,but network operators still need to manually configure individual device or the entire network.At the same time,the current Internet routing policy mainly adopts "topology-based static routing" or "planning-based traffic engineering" methods but the real-time network status is not fully considered.As a result,the current network architecture cannot fundamentally reduce the probability of network administrators’ manual errors,cannot plan and adjust traffic to quickly respond to real-time changes in network status,and it is difficult to achieve optimal segmentation of network traffic.The subject of this paper attempts to design a new network architecture:intent-driven intelligent routing network,which can automatically complete the configuration task according to the user’s freely described business or management requirements.At the same time,it is based on artificial intelligence technology that combines historical routing data and real-time network status to achieve intelligent routing calculations.The core of the network is to promote the intellectualization of network control by business or network management intent.In order to test and verify the feasibility of intent-driven intelligent routing network architecture,we need to design and implement an intent-driven intelligent routing prototype system.Intent is the core of prototype system.The main purpose of this paper is to design and implement the intent subsystem.The research of this paper includes three parts,clarifying the application scenarios and exact meanings of intent and designing intent expression paradigms;studying a flexible and extensible internet protocol for carrying intent information;studying the working principle of an intent-driven intelligent routing system and design the intent subsystem system architecture.The paper first introduces the related technologies of the research content,then it describes the research results of the definition and expression of the intent in detail and designs Intent Carrying Internet Protocol(ICIP),besides it analyzes the needs of the intent subsystem,and proposes the overall architecture of the intent-driven intelligent routing system and the outline design of the intent subsystem.The design and implementation of each module of the intent subsystem are then introduced in detail,and the subsequent system testing verifies the feasibility of the design scheme.The paper concludes with a summary of the content,describing the shortcomings in the current results and the follow-up work plan.
