Public Internet access system and public Internet access method based on software definition

Abstract

The invention provides a public Internet access system and a public Internet access method based on software definition. The access system comprises a client, an access agent module, a network adapter, a user center, and a dispatching center. A user is connected with the user center and the dispatching center through the client, and is connected with the access agent module through the client. The access agent module is connected with public Internet access resources through the network adapter. The system and the method of the invention achieve the goal of turning the Internet into demand-based public infrastructure, and meet the access requirement of user terminals, service systems and cloud computing platforms for public Internet access resources. Centralized control on whole-network data forwarding and data forwarding based on software definition are realized, and a data packet can be forwarded to any Internet access across the country according to a pre-programmed forwarding strategy. Separation between service system and physical location is realized, and the problem that the construction cost and maintenance cost are high for distributed across-region deployment of a complex service system can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of data communication, and in particular relates to a software-defined public Internet access system and method. Background technique [0002] At present, large-scale IT companies at home and abroad have large-scale information infrastructures (such as data centers), and these information infrastructures are often scattered across the country or even in various parts of the world. Information infrastructures communicate through high-speed Internet. Facilities provide external services by connecting to the Internet nearby through various access networks, and there are various types of Internet access, which may include leased line, dial-up, IPv6, etc. The existing Internet access methods have the following three problems: first, low resource utilization and lack of sharing. The line or IP is only limited to local sharing, and the resource utilization rate is low; the second is that the access method is fixed...

AI Technical Summary

Problems solved by technology

The existing Internet access methods have the following three problems: First, low resource utilization and lack of sharing

The line or IP is only limited to local sharing, and the resource utilization rate is low; the second is that the access method is fixed and cannot be switched on demand

The access method is limited by the physical network structure, and it cannot be flexibly switched between different Internets according to business needs; the third is decentralized deployment, which is inconvenient for maintenance and management

Each Internet egress needs to be configured with a separate control strategy, which is inconvenient to maintain. Due to the scattered locations, it is impossible to manage the Internet egress from all over the place
