Subject: Re: Will MPLS replace ATM in
near future?
Hi Shen,
Ur reasoning seems to be good ..But what i feel is MPLS
will help to make ATM and IP networks to co-exist than replacing ATM.Also, ATM
is a well-tested technology with all features..I think lot of traffic
engineering mechanisms in ATM is also applicable to MPLS environ..Also
many features now adapted in IETF for MPLS have come from ATM features
only..So,I dont think ATM will be out-of-day in the near future rather MPLS
will butress ATM usage .This seems to be possible but i am not aware whether
it is being done in the industry..It is for the industry to answer!!!

Hi:
I've noticed that the research on MPLS has come to a very hot spot in
past days. And, now Cisco and other company start to
provide MPLS
enabled interconnection product, both in backbone interconnection product
and those for access network. I even read about "ethernet over MPLS". I
think this will change not only current interconnection technology but also
those backbone transmission techniques.
Because, as I think, this means
now MPLS can take the place of
those high speed access network ( PPPoA,
PPPoE ) dominated by ATM, and the method how those subscriber channels are
multiplexed
into a up transmission backbone. If the backbone is also
made up of MPLS, the method will be more flexible and gives more service.
Also the variable length of MPLS frame will give
more effient usage of
physical channal.
So, I want to know is ATM will be out-of-day in near future ?
