Per the current project creation policy[1], I'm requesting endorsement
from the Networking and Xen Communities for the following proposed
project.
Project Name: R-Bridges
Project Synopsys:
Deliver R-Bridge (IETF TRILL) support on Solaris.
Project Purpose (and commentary):
This project will introduce R-Bridge support to Solaris, based on
the original work by Radia Perlman, and the work now being done in
the IETF TRILL working group. The goal is an IS-IS based
replacement for Spanning Tree in bridged networks, along with
Solaris support for the required bits of infrastructure to make this
useful.
Key components include at least IS-IS routing (RFC 1142 / ISO DP
10589), Ethernet bridging, and TRILL header processing
(draft-ietf-trill-rbridge-protocol), and may include various
learning mechanisms (IGMP/PIM) and R-Bridge specific optimizations
(ARP/ND). Related projects include Quagga, Ethernet bridge module,
Crossbow, and Nemo. If a Solaris wireless AP ever exists, that
would likely be involved as well.
(Some necessary background: no real work has been done yet. This is
still just a very early stage proposal. We've noted that Quagga has
an 'isisd', but of unknown maturity, and not usable yet on Solaris.
Similarly, there's a bridging project, but that hasn't progressed
much and the lead seems to be gone. Some of the important early
decisions to make include settling on a code base to use for each
feature and making those components usable.)
(TRILL itself could probably use any IGP, but it specifies IS-IS
because it gets closer than the others to an ideal of zero
configuration -- in particular, it skips over the interface
addressing problem that OSPF has. We likely will need STP support
as well, but other components are less clear, and the IETF TRILL
work itself is evolving right now.)
(Two of the attractive things for this project are getting started
early in the protocol design process -- instead of playing catch-up
-- and the potential for multiple immediately reusable
subcomponents, regardless of the actual deployment of R-Bridges.)
