Ahead of next week’s VMworld conference in San Francisco, SD-WAN vendor Talari Networks announced some new additions to its product line as well an update to its Adaptive Private Networking (APN) operating system.

The latest additions cover the bases on several SD-WAN deployment options, including an optical interface, virtual appliances, and improved cloud capabilities.

Talari’s updated APN 4.4 lets enterprise customers move the Talari SD-WAN controller to the cloud, which Talari says simplifies SD-WAN management. Also included in the update are features to expand management of traffic in the cloud to give APN more control over where SaaS and Internet traffic enters and exits the WAN edge.

Talari also beefed up the security features of APN by providing third-party-certified, FIPS-compliant IPSec tunnels as a virtual WAN option.

On the new-product front, the Talari Appliance VT500 is a software-only appliance that runs on VMware’s vSphere. The VT500, which sits on the edge, enables Talari’s Software Defined Thinking WAN capabilities to be installed by end users on commoditized hardware or embedded in a service offering from another vendor or service provider.

Lastly, the Talari Appliance T5200 features 10-Gb/s fiber-optic interfaces that were designed to expand the deployment scale of data centers. The T5200 can function as the network controller for a Talari SD-WAN, and it has various high availability options including fail to glass ports, active/active high availability pairs, and geographic redundancy.

SD-WAN takes aim at virtualizing enterprise WAN technology functions including branch office routers, VPNs, WAN optimization, and application delivery controllers (ADCs) by moving the functionality to the cloud. The Rayno Report predicts the total opportunity for SD-WAN services will be $7.5 billion by 2020.
