RE: Yahoo Post

Walter,

If you monitor and try to make sense out of the technical threads, you notice that there are a lot of companies with engineers posting on specifications. Many of them are not the usual FC companies, but they are clearly interested. Another example of the widespread interest is the sheer number of companies in the InfiniBand Trade Association:

infinibandta.org

For example, some telecos have router and switching architecture divisions even though they do not make products in a particular area.

Feb.99 Nordgren,Fieb & Jacquemin see the link DWDM and FC - Huge Potential Here. Looking back to early 99, ATM was mentioned all the time, now you rarely see ATM mentioned. DWDM and FC are starting to be mentioned everywhere. Congratulations to Douglas, J. & Walter for being the first to comment here, on this. I have always believed in the potential of these two technologies dominating the Internet. Owning Osicom and Harmonic since around 1996/97, both DWDM suppliers, I hoped DWDM and FC would take the lead someday. We are getting closer to taking over the Internet.

WDM-FC?
Open Interfaces Pursued For SAN
(02/04/99, 8:09 p.m. ET)
By Loring Wirbel, EE Times

Promoters of storage area networks (SANs)
made two independent efforts this week for
open interfaces operating at several layers in
the SAN protocol stack.

"In fact,with the advent of wave-division multiplexing on
Fibre Channel, proposed as a vehicle to bring
public-network carriers into SAN management, the
alliances have to consider scaling management tools to
service providers. Greg Beyer, CEO of Fibre Channel
switching specialist Brocade Communications, said that
"it doesn't require a huge leap of faith" to see switched
Fibre Channel meshes being connected over public
backbones. SAN management as a carrier service will
be feasible given updates in routing algorithms and
restoration concepts, he said, but the business model
needs to develop further before Brocade or other
companies are likely to offer management tools for
carriers."

JFieb: Fascinating find! Now if I could just translate it to English....
It sounds like progress is being made to standardize the software for SAN management. Everyone seems to be working together.
DWDM would be a natural way to enlarge the pipes.

When the Brocade CEO talks about public carriers and service providers involved with SAN management and SWITCHED FC webs over public backbones, he is talking about MCI/Worldcom, ATT, et al. Those are HUGE accounts and would require HUGE, fault-tolerant switches such as made by Lucent, Ascend, Cisco, Nortel. None of these big boys are in to FC at this time, as far as I know. The future is going to be very interesting for FC switch makers....... IMHO wj

Re WDM and FC Backbone
Louie, DWDM is cost effective primarily at long distance data hauling, and there have been some efforts made to accomodate the technology for short haul networks, (WANs & MANs). Fibre Channel is coming under scrutiny as a possible cost effective DWDM extension for the short haul data/voice trunks over fiber. I hope that helps?

More on FC & DWDM
Unclear on the concept of FC and DWDM interconnects?

Fibre Channel can operate as a data transport mechanism for multiple
Upper Level Protocols (ULP), with mappings defined for IP, SCSI, HIPPI,
ESCON and FICON, and ATM-AAL5 mapping. A single fibre channel port
can execute simultaneous transmissions of ULPs (e.g. ATM, HIPPI,& IP) through the same port.

SONET, HIPPI, and ATM are the most likely ULPs for data transport over
DWDM fiber. A Fibre Channel switched IP SAN/LAN/WAN/MAN can port to an
ATM or HIPPI DWDM trunk. If it can be done, it will be done, eventually.

Douglas

P.S. George, wish we could get royalties for discovering what was under
our noses all along. <g>

Makes FC sound like the Swiss Army Knife for digital data transport and also explains what 3COM, and CSCO might see in FC. Something for everyone. Thanks. But if the frame size is so big and roomy in FC and can carry more data than those shrimpy ATM frames why
don't they just designate a national backbone for FC over DWDM and forget the ATM, HIPPI, IP etc? Is it possible? Thanks in advance.

Re FC National Backbone, why not?
Distance limitations, remember, current max is 10k. But that is changing as we speak. Stay tuned.
