< BULAT SD-WAN solution
Recent active IT development has led to a serious change in services. For several decades the development of network architecture and equipment was evolutionary. However, in the last five years, there has been a revolutionary change in approaches to building, managing, and operating a network. This is due to the explosive growth in network traffic, the number of connected devices, and the speed of business processes. All this resulted in the complexity of maintaining distributed networks, imperfect use of expensive private channels, insufficient level of process automation, and difficulty of scaling.
Today’s main task is to create a business-centric IT infrastructure that can easily meet the needs of business units and adapt to changes in the company's strategy. While some progress has been made in the field of computing platforms by introducing server virtualization, data transmission networks remain a bottleneck that hinders technological development. The static architecture, the need to configure each device directly involved in the service, and the high probability of errors mean that the commissioning of new services or changing existing configurations can take weeks or even months.
The essence of the BULAT SD-WAN solution is to combine private communication channels into a single virtual network factory, centrally managed with an SD-WAN controller. For applications that use the resources of the factory, the network looks like an abstract "platform" with a set of resources that can be used based on the service requirements. Resource quotas, security policies, QoS parameters, and other service metrics are centrally assigned through a single network management platform.
In most cases, the solution involves the installation of additional devices at the network edge, which are managed by a centralized controller.
BULAT SD-WAN solution allows large enterprises, owners of MPLS networks, and government departments to achieve maximum RSPD infrastructure management automation by using Russian equipment and software. The solution is suitable for large enterprises with extensive networks distributed across the regions.
CPEs connect to SD-WAN gateways using VXLAN tunnels, forming an SDN factory as an overlay network. SD-WAN controller is responsible for managing the overlay network, i.e building the actual topology, creating transport services (L2 Point-to-Point, Point-to-Multipoint, Multipoint-to-Multipoint, l3 VPN).
