Intelligent Resilient Framework

Intelligent Resilient Framework (IRF) is a proprietary software virtualization technology originally developed by Huawei 3Com. It can connect and configure multiple network devices through physical ports and then virtualize the devices. This enables the unified management and maintenance of multiple devices.{{Cite web |url=http://www.h3c.com/portal/Products___Solutions/Technology/IRF/Technology_White_Paper/200901/624932_57_0.htm |title=H3C - Products & Solutions - IRF2.0 Technology White Paper |access-date=2010-12-15 |archive-url=https://web.archive.org/web/20101005184935/http://h3c.com/portal/Products___Solutions/Technology/IRF/Technology_White_Paper/200901/624932_57_0.htm |archive-date=2010-10-05 |url-status=dead }} This technology is similar to the Cisco Virtual PortChannel (vpC).

History

This technology was originally developed by 3Com and released in 2003 as XRN (eXpandable Resilient Networking).{{cite web |author=David Newman |date=3 March 2003 |title=XRN Interconnect architecture |url=https://www.networkworld.com/article/895292/lan-wan-xrn-interconnect-architecture.html |access-date=26 June 2014}} When HP Inc. purchased 3Com in April 2010,{{Cite web |last=Stricker |first=Ben |date=April 12, 2010 |title=HP Completes Acquisition of 3Com Corporation, Accelerates Converged Infrastructure Strategy |url=https://investor.hp.com/news-events/news/news-details/2010/HP-Completes-Acquisition-of-3Com-Corporation-Accelerates-Converged--Infrastructure-Strategy/default.aspx |website=www.investor.hp.com}} the technology was renamed to IRF.

Overview

An IRF virtual device appears as a node on the network, which can be connected to in order to manage all members of the virtual device. The IRF is designed to combine the cost-effective benefits of box-type devices with the reliability of chassis-based devices. IRF proponents claim that an IRF-based network increases network resilience, performance, and availability, while also reducing the operating complexity.{{Cite web |title=Buyer's Guide: HP's Intelligent Resilient Framework (IRF) put to the test {{!}} Computer Weekly |url=https://www.computerweekly.com/feature/Buyers-Guide-HPs-Intelligent-Resilient-Framework-IRF-put-to-the-test |access-date=2024-08-11 |website=ComputerWeekly.com |language=en}} In simulated tests, IRF was found to be resilient to severe induced failures.
