Benefits of Deploying the Avaya Surge™ Solution for Any IP Network

The Avaya Surge™ Solution is designed to work in an SDN Fx fabric environment. But many companies don’t have the luxury of deploying a full Ethernet fabric before they deploy their IoT-based applications. Avaya Surge release 1.0.1 (November 2016) added support for non-fabric IP networks.
The Surge IoT Controller works essentially the same way as in the SDN Fx fabric deployment, except the Open vSwitch on the Open Networking Adapter can’t automate network provisioning. Therefore, the VLANs must be configured manually on the network. The solution still provides centralized inventory, white list profiles, flow filtering, and a single pane-of-glass status for all Open Networking Adapter-enabled IoT devices. Without the SDN Fx fabric infrastructure, segmentation is limited to VLANs that aren’t stealthy and mobility requires manual network service set-up and tear-down. For environments where devices are static, the IP-only version of Avaya Surge may suffice until a full fabric can be deployed.
The risk profile of IoT doesn’t lend itself to “good enough” solutions for long. When a company’s network and data are compromised, less than best practices will be criticized in the media, in the court room, and, as in the Yahoo case, impact executive pay. Avaya Surge Release 2.0, scheduled for the second quarter of 2017, adds IPSec encryption and tunneling to an IP-only deployment. (IPSec will be available for SDN Fx deployments as well.)
A HyperSec gateway is deployed to coordinate the IPSec functionality with the Open Networking Adapters. The HyperSec gateway terminates the IPSec connection from the Adapters and directs the data to the correct VLAN to reach the target application server. Return data is encrypted and sent to the appropriate Adapter, which terminates and forwards the data to the IoT device. The addition of the HyperSec gateway adds encryption to the data on the network, while adding mobility to the solution. The Adapter is able to dynamically create the IPSec tunnel to the HyperSec gateway, reducing manual network management.
The HyperSec gateway is deployed as an active/standby pair. Each Adapter will be set up with primary/secondary tunnels. If the primary is not available, the Adapter will communicate over the secondary tunnel to the HyperSec gateway. The HyperSec cluster is headless. Configuration information is maintained in the Surge IoT Controller. This greatly simplifies scale-out clustering of the HyperSec gateway.
I will blog more about the HyperSec solution closer to availability. Keep in mind that you can get started with Avaya Surge on an IP network today and add IPSec when it becomes available. Also, it is not an all-or-nothing solution. Critical IoT components and services go through the HyperSec gateway and less critical and stationary workloads are deployed with IP and VLANs. Furthermore, SDN Fx fabric can be incrementally added to portions of the IoT portfolio to gain the value of hyper-segmentation, native stealth, and automatic elasticity.
Look at all of this through a different lens. I was talking to a friend, an intellectual property rights attorney, about the exposure that companies face from data breaches. It was one of those conversations where he wanted to know more about the technology and I was curious about his perspective as someone who makes money from a company’s problems. He was especially interested because legal firms are getting $500K to $2.5M for a simple breach defense. When looking at these numbers, I think that even if a company isn’t found culpable in a data breach, they could spend a lot of money in defense. So, it’s probably best to invest in the infrastructure to deploy IoT projects in a safe and sane manner.
In my recent blogs about the IoT, I’ve looked at how the IoT enables Digital Transformation and examined a business-first approach to IoT technology adoption. Then I looked at how Avaya’s SDN FxTM provides a foundation for a safe and sane IoT deployment. Finally, I introduced the Avaya Surge™ Solution, which extends network fabric to IoT devices and provides centralized device management, protection, and flow filtering.
