It's great to have a good old enemy again.
I'm trying to penetrate an IBM shop with our networking
products and could use some competitive information.
Has anyone heard of any comparisons between the
IBM 2220 Nways* BroadBand ATM Switch and our Gigaswitch ATM.
Here is some of the things they are saying about their switches.
Switch-on-a-Chip is based on a single chip switch element from which
larger, self-routingsingle-stage or multistage switch fabrics can be
constructed. Because the switch design is scalable, multiple chips can
be connected in series or in parallel to create large switch fabrics
with higher performance. By using output queues that are configured as
a dynamically shared memory, the switch delivers high performance
without discarding any packets.
Thanks in advance,
Jim

Hello Jim,
Is the Nways2220 real ? Last time I saw one it was a repackaged Cascade
switch, but IBM would not really admit it.
I thought the switch-on-a-chip (Prism project) only applied to the
8260.
Back to the Nways2220. The product that was presented at Telecom'95
was supposed to have a lot of Telco WAN features: lots of CBR VCs, lots
of VBR VCs, all sorts of VP capabilities, plus non-ATM WAN lines ...
Apart from those displayed (non running) at T'95 I haven't seen any
more 'real' 2220s. All I've seen were Cascade boxes.
FWIW.
Cheers, Patrick
