Managing CPE devices > The BFD protocol
The BFD protocol
The BFD protocol
Kaspersky SD-WAN supports the use of the Bidirectional Forwarding Detection (BFD) protocol for fast (within one second) detection of network connectivity problems on data channels and links. When a problem is detected, BFD relays information about the problem from the
data plane
to the The part of the network that processes and transmits traffic between different locations and devices. The data plane uses network protocols and algorithms to efficiently route and deliver traffic over the network. Consists of CPE devices.
control plane
.
The control part of the network that controls the transmission of traffic packets through CPE devices. Performs functions such as network discovery, route calculation, traffic prioritisation, and security policy enforcement. The control plane allows centrally managing the network by providing a full-scale view of all performed operations. Consists of an orchestrator and an SD-WAN controller.
Between BFD peers, a BFD session is established, as part of which they exchange control packets to detect network connectivity problems. If a problem with network connectivity occurs during a BFD session, the routing protocol session is terminated on the corresponding interface of the CPE device, and routing tables are subsequently rebuilt.
