i suppose that an underlying assumption of mine was that microsoft's market
is non-competitive AND cisco has a chance of breaking into the carrier
market BECAUSE both companies are leaders in terms of directional
flexibility. do you see it differently?
as for hsrp, even if it is functionally identical, their claim about
standards is STILL misleading (in a sense that has misdirected many, many
it budgets).
in some cases where they have an approach which predates a standard, they
will arrange for IOS to use either,
or, they will interoperate/exchange information with non-cisco
implementations
or, as in the case of hsrp, they don't provide support for vrrp
unfortunately, standards compliance seems to be an area where linguistic
precision is absolutely vital.

HSRP has significant ancestry in DEC's cluster protocols. The IETF's

Intuitively, I think there are important differences, at least in
part, for the market of Microsoft and Cisco. The argument is not as
strong in the enterprise networking as the carrier networking space.
In carrier networking, however, the "customers" themselves push the
technologies and may very well introduce approaches of their own.
Even more importantly, carriers have a century or so of using
standards-based approaches whenever possible.
It's informative to look at how well Juniper has competed with Cisco
in the carrier router space, in part because they don't have the
baggage of the legacy mechanisms IOS needs to support. Also, Nortel's
installed base in optical networking is far greater than Cisco's.
I suppose my point is that the carrier market is much more
competitive than the enterprise networking market, which in turn is
more competitive than the market that Microsoft inhabits.
