Demand definition network implementation method and network architecture

Abstract

The invention discloses a demand definition network implementation method and a network architecture, and relates to the field of network architectures. The method comprises the steps of collecting and classifying the user demands, dividing each type of user demands into a user demand set, and adjusting the user demand set in real time according to the user demands; judging the satisfiability of each user demand set according to all available network resources, and establishing a meta-slice for each user demand set which can be satisfied; and establishing mapping between each meta-slice and the required network resource, and configuring and executing the network resource corresponding to the meta-slice. According to the invention, the network can be dynamically adapted according to the dynamic changes, discretization and differentiated user requirements.

Description

technical field [0001] The invention relates to the field of network architecture, in particular to a method for realizing a requirement definition network and a network architecture. Background technique [0002] The basic capabilities of the network include three dimensions of transmission, computing, and storage. Its functions are mainly manifested in three aspects: hardware resource sharing, software resource sharing, and information exchange between users. In any case, the ultimate goal of the network is to satisfy all users in the network. This is also the significance of the existence of the network and the driving force for its development. Therefore, the demand is the fundamental factor that determines the network architecture and attributes. [0003] In the current network, meeting user needs is realized through two phases of network design and network operation and maintenance. Network design provides a basic network construction solution, and network operation a...

Therefore, the degree of matching between network architecture design and construction and dynamic and discrete user needs is hard to say

On the other hand, the processing of dynamic changes in the network operation and maintenance phase also mainly relies on manual implementation, which has poor real-time performance, insufficient precision in meeting requirements, poor matching with real-time network status, and poor utilization of network resources.

At the same time, user needs may change over time. If you rely on manual efforts to adapt to changes in demand, it is neither real-time nor accurate enough, and the implementation cost is also high.

[0004] The changes in network architecture brought about by software-defined networking do have a great positive impact on the development of the network. Who is more reasonable to define and how to efficiently implement the above definition, which makes the application in products face some obstacles
