XRN
XRN (eXpandable Resilient Network) is a 3Com LAN technology built into the
software and hardware of your Switch that offers high availability, scalability, and
connectivity.
XRN is supported by the 3Com Operating System on the following Switches
installed with Version 1.0 software or later:

XRN is standards based. The 3Com only proprietary technology operates across
the Fabric Interconnect ports.
This section contains a glossary of the common XRN terminology.
XRN is developed by 3Com that allows you to implement fault tolerant, high
performance and scalable multilayer networks.
Fabric Interconnect is the interconnection between XRN Switches that form the
Distributed Fabric.
XRN Distributed Fabric is the term used to describe interconnected devices
supporting XRN.
DDM allows Switches in the XRN Distributed Fabric to behave as a single
managed entity, irrespective of the form factor or Switch deployed. For further
information see page 673.
DLA is the configuration of Aggregated Links across interconnected devices in
the Distributed Fabric. 3Com and non-3Com devices can connect to the XRN
Distributed Fabric using DLA. For further information see page 674.
DRR provides distributed routing and router resiliency across an XRN Distributed
Fabric. For further information see page 673.
