RE: Please help to clarify some things!


In terms of not confusing issues, can you clarify your statement "it will
not do for the carrier transmissions systems".

Do you mean that IP based network management (a) does not possess the
functionality, or (b) the people who may procure the equipment have other
ideas so they will not buy this irrespective of technical merit?

Further can we clarify here what you mean by "carrier transmission systems".
If these are existing pieces of equipment what you say is trivially true. If
not then you presume that there are entirely new systems to be built for
which either (a) or (b) above. Perhaps some of the purchasers can articulate
their view on (a) themselves.

I am not in any way suggesting a change in the way that IP based data
communications systems change the way that they do network management.  I am
stating that it will not do for the carrier transmissions systems.  Please
not confuse the separate issues.

Customer Ethernet switches at either end of a WAN path will still use the
network management that is so common.  It may be that some transmission
equipment vendors may even be convinced to provide some SNMP visibility at
10GbE interface on the long haul transmission line terminating or DWDM

The common service carriers will want to have something other than SNMP
available for the equipment that they own, and the element management
communications for that equipment will be carried out of band.  This is a
totally separate issue from the SNMP management of Ethernet switches.

Thank you,
