Extreme Integrated Application Hosting

Extreme Integrated Application Hosting (IAH) architecture provides a flexible and open solution that enables organizations to deploy high-performance and flexible visibility applications pervasively throughout their network for improved monitoring and troubleshooting. Enabled by the Network Operating System (NOS), this preconfigured Quick Emulator (QEMU) Kernel-based Virtual Machine (KVM) environment leverages high performance x86 CPUs to host these applications, extending visibility customized to the business and operational needs of the organization across the entire network.

The QEMU KVM environment supports several pretested and well-known packet capture applications in a Linux virtual machine, including Wireshark and tcpdump. There are a wide variety of additional applications, tools, and utilities that organizations are able to run in this environment, such as data analytics applications, packet generators, monitoring tools, troubleshooting utilities, and many others. While the QEMU KVM environment is open and can host any application, it is designed and ideally suited for networking applications, tools, and utilities.

IAH architecture supports the creation and use of virtualization domains, such as virtual machines, and Docker containers. This design creates a common-use host, which coordinates and automates multiple guest-networking functions into chains. The hardware boots into the virtual Linux OS, providing the ability to run additional applications or services within a specific virtual machine or a Docker container, and simultaneously supporting the regular functionality of the switch.

Yet Another Next Generation (YANG) model is used to manage configuration and retrieve operational data. You access the YANG model through Representational State Transfer Configuration Protocol (RESTCONF) using a northbound interface, namely ExtremeCloud IQ ‑ Site Engine, that provides an additional way to configure and monitor the switch. For more information on RESTCONF, see Representational State Transfer Configuration Protocol (RESTCONF) Fundamentals.
