In today's world, businesses increasingly demand flexibility and scalability of networks in information technology. Software-defined networks, where network management is separated from traffic transmission devices, replace the traditional architecture
Improving data transfer quality
The flexible use of all existing communication channels allows the network to achieve high fault tolerance, and the ability to manage traffic at the application level simplifies the management of physical devices in the network, significantly improving the data transfer quality for the services used.
Use Case
Deploying a network of distributed branches (data centers) based on multiple communication channels
Organizing quality control of the used channels
Combining routing and traffic control policies in your organization's data network
Automatic control of bandwidth considering existing data connections
The composition of the subsystem
The SDN (SD-WAN) controller is an essential component of any SDN solution. It directly controls all endpoint devices and connections by implementing data routing policies.
01; Management (administration) subsystem; It is the single endpoint for the management policies of the SDN network and also provides an interface for managing the devices of the SDN network. It is also responsible for monitoring, troubleshooting, and resolving issues in the network;
02; Data transmission subsystem;Responsible for establishing secure connections and transmitting traffic over the network in accordance with the existing quality of service policies and parameters. It involves direct data transmission devices (routers);
System benefits
Reducing costs
Reduce maintenance and operational costs of the network infrastructure through simplified management
Office deployments
Quick deployment of new offices without the need for technician (ZTP) involvement
Management
Intelligent application traffic management
SLA
Guaranteed SLA assurance for business applications
Quick response
Quick response to changes in the network
Optimization
Optimizing the use of existing communication channels
Reduce costs
Reduce the costs of purchasing expensive terminal equipment
SD-WAN Controller
Control and management functions are performed by a single SD-WAN controller, not by multiple network devices
