What Are the Primary Functions of SD-WAN Edge?

SD-WAN edge functions are two-pronged: software and hardware. The software component of SD-WAN enables network devices to be managed centrally. The edge devices download control information from the controllers and send network telemetry to inform the controller of network status changes. The centralized controller handles the control plane calculations, while the hardware component of the SD-WAN edge is responsible for packet forwarding.

SD-WAN enables organizations to have deeper visibility into the entire network and granular control over bandwidth allocation. It also allows the organization to make changes, such as limiting the bandwidth allocated to particular applications. With the help of this technology, organizations can benefit from cost-effective, high-bandwidth broadband Internet. In addition to reducing bandwidth costs, SD-WAN allows organizations to reduce network complexity and increase business agility.

The SD-WAN edge enables companies to connect to cloud resources and data centers. As more enterprises adopt public cloud services, the need for SD-WAN will only grow. The SD-WAN edge is a flexible tool that allows organizations to quickly move data to different locations and data centers.

The SD-WAN edge also helps companies secure remote workforces with security and performance. Its software intelligence enables users to access applications and data from anywhere, whether on-premise or in the cloud. With the SD-WAN edge, companies can also manage the edge of their network remotely with the help of a cloud management platform.

Provides application-layer control of application service policies

SD-WAN edge-platform Application Control is a security solution that allows an organization to enforce security policies for individual applications and groups. As a result, it helps achieve a zero-trust security model and improves network performance. It also lets an organization prioritize traffic based on the type of application being accessed. For example, traffic from high-priority applications can be prioritized, and low-priority traffic can be restricted or even blocked.

Application-layer policies build on the authentication layer and provide fine-grained access control. These automatic checks eliminate the need to write multiple policies for each service. These policies can be significantly more granular than existing policies. They can be as specific as an API method or resource.

The application layer is at the top of the OSI model and provides services for users. For example, the Web uses the application layer to provide user interfaces and access to data. This layer also enables email and web browsers to communicate with each other.

Improves application performance and resiliency

Increasingly, enterprises rely on enterprise-grade SD-WAN technology to reduce WAN expenses and improve application performance. SD-WAN offers numerous benefits,, including centralized management, flexible application policies, routing, interface support, analytics, and software-as-a-service. It also saves time and money through zero-touch provisioning.

Moreover, SD-WAN is a cost-efficient alternative to MPLS. In addition to providing a dedicated connection, SD-WAN supports the automatic provisioning of premium networks and third-party services. It can also be configured to support VPNs on non-MPLS networks.

SD-WAN is a virtual network that securely connects users to any application. It also provides a flexible infrastructure that supports multiple cloud environments and can scale.

Provides A WAN transport agnostic overlay network

SD-WAN Edge is a software-based network that creates an overlay network on top of an existing WAN transport.

SD-WAN Edge enables businesses to use any WAN transport, from fiber to Ethernet. It can also monitor application performance on each link and choose the best path based on real-time conditions and policies. In this way, businesses can optimize the performance of their network and maximize their ROI.

The key benefit of SD-WAN Edge is its ability to connect to any location or network and eliminate critical application downtime.

Provides NGFW, IPS, encryption, AV, and sandboxing capabilities

The IPS technology is increasingly being integrated into NGFW solutions. NGFWs that include it can prevent known vulnerabilities, brute-force attacks, and denial-of-service attacks. In addition, some NGFWs come with a network sandbox for advanced malware protection. This allows administrators to test malicious traffic without impacting production and to detect and prevent attacks.

The most common objective for purchasing an NGFW is to improve compliance. However, it can also help with risk management and cost management. Moreover, it can help drive innovation and improve business process outcomes.
