智能VPN在接入路由器上的設計與實現(xiàn)
[Abstract]:With the increase of business branches, industry sites, and the rapid development of the Internet of things, the demand for Internet access has become increasingly strong, and the use of traditional access lines has gradually been unable to meet the needs of customers, such as high bandwidth. People have been trying to find a way to solve the bandwidth bottleneck and improve the reliability of the network system under the existing conditions. The link aggregation technology solves this problem very well, so it is very important to research and implement the link aggregation technology on the network equipment. Based on a solution of access router (Access Router,AR) of Huawei Technology Co., Ltd., based on the deep research of the hardware and software of AR equipment, this paper completes the implementation of link aggregation technology on AR, and it is named Intelligent VPN, (SVPN.). Firstly, this paper analyzes the requirements of SVPN, and clarifies the objectives and values of the requirements. Secondly, the function design, the overall module design and the sub-module design of SVPN are described in detail. Two working modes of SVPN are designed and completed: single machine mode and on-line mode, two scheduling modes: Priority scheduling based on link priority and Overflow scheduling based on link bandwidth. The data structure of SVPN and the realization method of the specific function are designed. Finally, the local environment is built, and the function and performance of the system are fully tested, which verifies the reliability and stability of the system.
