Avaya Architecture Designed to Make IoT Easier, More Secure
At the Massachusetts facilities, Keene, Adamyk and other Avaya officials demonstrated the architecture in a lab. The demo included 600 ONAs controlled by a single OpenDaylight-based SDN controller from Avaya partner Inocybe Technologies. The demonstration showed both how easily IoT devices can deployed on the architecture using the ONAs and the scalability of the platform. The ONA is powered by a dual-core CPU and includes an Ethernet port on each end—one for the device being connected, and the other for the connection into the infrastructure. The ONA is scanned and the serial number recorded by Avaya software, and the device shows up on a GUI interface while the SDN controller conducts the two-factor authentication. Routing policies then can be set to determine what information from the device will go where. During the demonstration, three people with limited technical capabilities were walked through an onboarding process that took only a few minutes. Once online, Avaya's Fabric Connect technology will see and manage the device. In keeping with the idea of making the architecture as open as possible, future versions will be able to use other management platforms other than Fabric Connect, officials said.Avaya officials see the architecture and ONAs as keys to enabling highly scalable IoT environments that can securely deploy, manage and track thousands of connected devices. Adamyk said healthcare facilities—with the fast-growing number of devices and a highly regulated environment—were a good fit. Such facilities on average have 12 connected devices per bed, and a Veterans Administration hospital can have upwards of 10,000 total connected devices. Officials expect Avaya and partners also to develop versions of the architecture and Avaya software optimized for other industries.
The Avaya architecture includes three levels for scalability, manageability and security, officials said. There is the OpenDaylight instance that can support up to 660 OpenFlow and NetConf ONAs, and multiple paired instances of Avaya's OpenDaylight controller to act as a cluster behind a load balancer from Kemp Technologies, enabling the cluster to be viewed as a single entity by the IoT devices. The combination of 255 OpenDaylight controller nodes at 660 devices per instance comes to 168,300 devices being controlled, they said. The architecture also includes a distributed main-memory database and messaging bus.
