Referring to fig. 1 to 4 of the drawings of the present specification, a cloud network convergence-based network system and a cloud optimization method thereof according to a first preferred embodiment of the present invention are explained in the following description. The network system cloud network fusion platform comprises an operation background, hardware equipment and a user side APP. The network system cloud network fusion platform of the preferred embodiment of the invention is mainly used for solving network problems of enterprise multi-branch networking, multi-branch and cloud networking, cross-cloud networking, enterprise personnel mobile office, access application optimization and the like. It is worth mentioning that as data analysis, media traffic, storage requirements, and data backup increase, more and more data is being transmitted between data centers, cloud environments, branches, and other remote locations. The growth in traffic has necessitated optimization of the performance of Wide Area Networks (WANs) and the applications running thereon. With the steady rise of traffic, network administrators can also see that the delay in the transmission of sensitive data is increasing. The network system of the present invention provides WAN and application performance optimization for scalability and throughput required for traffic transmission. In addition, the network system of the present invention uses techniques such as deduplication, compression, and other protocol optimization to optimize performance, including increased bandwidth capacity, network latency, monitoring and management of protocols and overall network traffic.
The network system based on cloud network convergence comprises a user side access device 10, a cloud central controller 20 and a service access gateway 30 for providing access and convergence and guiding traffic to a backbone network, wherein the user side access device 10 is in network connection with the cloud central controller 20 through the service access gateway 30. The customer premise access device 10 may be implemented as an enterprise site or data center edge access router device, and the cloud central controller 20 is used to manage and configure the access of the service access gateway 30 and the customer premise access device 10, so as to implement several scheduling and management of the whole network.
It will be understood that the subscriber access device 10 includes a fixed address router and a mobile subscriber access device, such as a mobile communication device.
As shown in fig. 2, the service platform based on the cloud network convergence network system is divided into four layers, including an access layer, a data layer, a control layer, and a management layer, where the access layer mainly passes through various types of client devices such as CPE \ UCPE \ VCPE; wherein the data layer comprises multi-WAN access, multi-WAN pooling, multi-WAN bundling, etc.; the control layer comprises intelligent routing, intelligent QoS, overlay tunnel, TCP/UDP wide area network transmission optimization, NFV safety and the like; the management layer comprises intelligent application identification, security/operation and maintenance strategy unified management, equipment unified management, whole network unified monitoring and the like.
