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.
Telecommunication equipment, including virtual machines, located at the client premises. Used to connect the client location to the SD-WAN network, establish tunnels and transfer traffic between client locations. Traffic can be sent to a data center to provide network functions such as routing protocols, intrusion prevention, or anti-virus protection.
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.
6-bit values that define the priority of traffic packets and the type of service required. They are used in combination with traffic classes to provide appropriate priority and bandwidth to critical network traffic, such as traffic from audio and video streaming applications.
This feature allows a CPE device to notify its peers about an imminent restart, for example, when using BGP. This lets the peers immediately remove the relevant CPE device from the routing table, without waiting for the timeout to end.
Controls the solution infrastructure, functions as an NFV orchestrator (NFVO), and manages network services and distributed VNFMs. Can be managed via the web interface or REST API when using external northbound systems.
Pre-deployed ready-to-use network functions that are uploaded to the orchestrator web interface. The orchestrator can then handle additional configuration of the PNF.
A package, in TAR or ZIP format, that contains the data necessary for deploying and managing the PNF.
Centrally manages the overlay network and network devices in accordance with the service chain topology via the OpenFlow protocol. Deployed as a virtual or physical network function.
CPE device that has the SD-WAN gateway role. Gateways establish tunnels with all devices on the network, including other gateways, thus providing connectivity between all devices and the SD-WAN Controller. You can install multiple gateways for fault tolerance.
Technology for building communication networks in which the control plane is separated from the data plane and is implemented in software using a centralized SDN controller.
Approach to building software-defined networks using a global computer network. SD-WAN networks allow connecting local area networks and users in geographically dispersed locations.
A logical entity within which an individual SD-WAN instance is deployed. Solution components such as network service components, users, and CPE devices are assigned to a tenant, and subsequently, tenant administrators can manage the assigned components. For example, you can create a separate tenant for a customer of your organization.
CPEs with additional support for Virtual Network Function deployment. Note that the device must have sufficient hardware resources to avoid involving the data center or the cloud when providing the VNF.
Manages computational, networking, and storage resources within the NFV infrastructure. Serves to connect network functions with virtual links, subnets, and ports.
Can be deployed in the data center or on a uCPE device. Deploying the VIM in the data center implies centralized management of the VNF lifecycle, while a VIM deployed on a uCPE device allows delivering VNFs to remote locations and managing these VNFs locally. The deployed VIM must be added in the orchestrator web interface.
The OpenStack cloud platform is used as the VIM.
Network functions implemented as virtual machines on Commercial Off The Shelf (COTS) computer platforms.
Manages the lifecycle of virtual network functions using SSH, Ansible playbooks, scripts, and Cloud-init attributes.
A package, in TAR or ZIP format, that contains the data necessary for deploying and managing a VNF.
