Title : The Architecture of an RBridge Solution to TRILL
Author(s) : E. Gray
Filename : draft-gray-trill-rbridge-arch-01.txt
Pages : 33
Date : 2006-6-27
RBridges are link layer (L2) devices that use routing protocols
as a control plane. They combine several of the benefits of the
link layer with network layer routing benefits. RBridges use
existing link state routing to provide higher RBridge to RBridge
cross-section bandwidth, fast convergence on reconfiguration,
and more robustness under link interruption than an equivalent
set of conventional bridges using existing spanning tree
forwarding. They are intended to apply to similar L2 network
sizes as conventional bridges and are intended to be backward
compatible with those bridges as both ingress/egress and
transit. They also attempt to retain as much 'plug and play' as
is already available in existing bridges. This document proposes
an RBridge system as a solution to the TRILL problem. It also
defines the RBridge architecture, defines its terminology, and
describes basic components and desired behavior. One or more
separate documents specify the protocols and mechanisms that
satisfy the architecture presented herein.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
