RE: switch vs. router

[huangjianbo]

Dear Mr. Yao,

So many replies, I am reading them.

Some idea now, but still not very clear.  I want the most distinctive ones.

Concluded from these mail, one most attractive is the router decrease TTL,
while switch not.  And some are talking about progagation of the broadcast.
I need further think.

Another question I want to ask is that if the layer 3 switchs own ip
addresses for every ports?

hi everyone,
i am a beginner for this ietf. i am now interested in router hardware design, but 
i need help.

 For better performance, i have to use ASICs in the router as more as possible. 
How can i design a router which will be both best performance and scalable for the 
future?? is there any information such as design-check-lists i can get form the 
Internet?? Thank you for your help.

Thank you very much!

Deja Vu

[Phil Karn]

Well, here I am at the Minneapolis IETF. And I'm overwhelmed by a sense
of deja vu.

Having to stay at the Marquette hotel 3+ blocks away because, living
on the west coast, I'm at least 50 milli-light-seconds farther away
than most of the people contending for the token number of on-site
hotel rooms when the meeting site is announced.

The much-touted "skyway" that is inevitably locked when you want to
return to your hotel, forcing an unprotected late-night dash out on
the Martian, uh, Minneapolis surface if you didn't have the foresight
to lug your spacesuit, uh, winter coat with you all day.

The countless eateries in said skyway that (even when the skyway is
open) always seem to be closed whenever you're looking for food.

The electronic outdoor temperature sign in the skyway reading
"39". The units aren't mentioned. Kelvins?

The stockbroker's electronic sign showing the Dow trying to break
10,000.

I understand the reasoning for holding the IETF here -- to discourage
all but the most highly motivated from attending. But it doesn't seem
to be working. So why, oh why, can't we just permanently move this
thing to (say) Las Vegas, where there are hotels actually large enough
to accomodate us, and where the winter climate is actually survivable?

Mime format

[lionel_gauliardon]

Sir,

I am working on a new prg to analyze mails that were "encoded" in Mime format
and have two questions about this one.


Well ... the first :

In the case of Message Media Type, External-Body Subtype I don't understand very
well ftp, tftp and anon-ftp access types.

 Is the file (which is indicated with Name, Site parameters) present in the
mail ? Who executed ftp command, is man who send the mail or man who received it
?



Second and last question :

Always in case of Message Media Type, External-Body Subtype but Mail-Server
access-type.

 When and how this command can be used ? I don't know how I can used this
one with my mail server.



Thank to your answers.

 Lionel.

It is a set of parameters created by the *sender* of the mail, that tell the
*recipient* "here - run FTP like *THIS* to get the file".

We probably would have just put a URL like ftp://ftp-server.whatever.dom/some/path
instead, but that section of MIME was done in the early 90's and pre-dates
URLs.

It's not handled by your mail server.  It's handled by your mail *CLIENT*

Even with Spring in MN, this is probably still a good idea.  Or New

And, if they do, how do they tell them it's OK to turn them back on? :-)

(The difference, of course, is that there's no Hearing Aid VII, with a wireless
connection to let you listen to Web pages or something...yet.  The flight
attendants can't keep up with the tech; and better for them to err on the side
of caution.  The remaining question, of course, is how come the airplane

they'd be interested in the liability benefits, if nothing else.  :-)

 I think the best place to eat in Mpls is at Kypros Restaurant, 14th
 and Nicollet...right by the convention center. It is Greek/Cypriot
 food. Now, I'm not saying this because I own the place, but rather,
 because it is IETF friendly.

Re: switch vs router

[Claudio Isaias Bernal Montalvo]

I hope the following lines can help to clarify the point:

Layer-2 switching is hardware based,wich means it uses the MAC address from the
host´s NIC cards to filter the network. Switches use Application-Specific
intergrated Circuits( ASIC´s) to build and maintain filter tables instead of
that routers uses ip adresses  wich is layer 3 information to buid and maintain
routing tables

Layer-2 switches are fast because they don´t look at the network layer header
information( like routers do), looking instead at the frame´s harware address
before deciding to either forward the frame or drop it.

What makes layer-2 switching so efficient is that there is no modification to
the data packet, only to the frame encapsulating the packet.since no
modification of the data packet is performed( routers make decitions after check
ip network address layer-3 information), the switching process is faster and
less-error prone than routing.

Bridged networks break up collision domains, but the network is still one large
broadcast domain. Layer-2 switches (bridges) cannot break up broadcast domains,
wich can cause less performance and limit the size of the network. Broadcast and
multicasts, along with the slow convergence of spanning tree, can cause major
problems as the network grows. Because of these problems, layer-2 switches
cannot completely replace routers( layer-3 devices) in the internetwork.

They can; today's fleet is pretty old.  A lot of the Boeing 737's were put
into service
in the '70's.  The 727's are even older. 

The newer aircraft would not likely have the same problem, however, one size

What's really ironic in your mentioning this (in a deju vu thread) is that
the Dow first hit and closed above 10,000 when we were here in 1999.  I

It's considered impolite to port-scan hosts on the IETF net.

Manhunt Closes Mall of America


By THE ASSOCIATED PRESS

BLOOMINGTON, Minn. (AP) -- Police closed the biggest shopping mall
in the nation Tuesday and searched hallways, bathrooms and broom
closets for a man wanted in three states.

Re: Deja Vu

[Joel Jaeggli]

This discussion seems to get rehashed in one form or another everytime we
have a meeting it seems...

due consideration when hosting the meeting in the US (or anywhere else)
involves placing it in a location with major international air-routes to
the pacific rim and europe (and the US if outside)... New Orleans, San
Antonio, Las Vegas and my hometown (eugene oregon) aren't really in the
running when you compare them to chicago, sfo, atlanta and so on... Flying
to secondary airports on an international itinerary or worse leaving from
a secondary airport and arriving at another on the other end is
logistically complicated, and expensive, which substantially reduces the
accessiblity of the ietf.

centrality, like on the network, has more to do with physical
interconnectedness than geography.

FYI: We will in that case not run out of hotel rooms in the ice hotel 
(built out of ice-blocks) because they "just" increase the number of 
rooms of the hotel according to the number of bookings they get.

You can also get various liquid drinks really served "on the rocks"...

"router" is the technical term for any device which forwards data based
on Layer 3 information.

"bridge" is the technical term for any device which forwards data based
on Layer 2 information.

"switch" is a marketing term meaning "fast".

Therefore, "L2 switch" means "fast bridge" and "L3 switch" means "fast
router".  There are also ATM switches, telephone switches, etc.
"switch" without any qualifiers is essentially meaningless unless
everyone agrees on the context -- and obviously those responding to this
thread are not in agreement.

None of those details is relevant.  A proper L3 switch (er, fast router)
will do the exact same things as a normal router.  If a particular
product fails to handle certain packets or fields properly, it doesn't
mean it's no longer a router -- it's just a non-compliant one.

Gee, you noticed this too, huh?

As for the "US-centric" accusations, I have no problem with holding
the IETF in various countries around the world. But when it *is* held
in the US, adequate facilities should be selected.

Re: Deja Vu

[Mikael Degermark]

Guys, 

I've lived in Lule a substantial part of my life. 

Moved to Tucson, AZ after a winter with -43 C (about -47 F).

I fear we would lose a large fraction of the IETF crowd if we 
did Lule in January. Seems like the wrong kind of darwinian
selection to apply!

add to it the fact that for most parts, the domestic air services
in the US leave a lot to be desired.  I travel almost every other
month to the US of A and it seems that a flight on a domestic
route taking off on time is more of an anomaly than the norm.

In all the years I've been attending the IETF (too many), the Minneapolis 
Hilton has the best facilities, best sized rooms, most cookies and pops, 
and the best run meetings of the bunch. Who cares what the temperature 
outside is?
