(CMD). Compatibility Mode is implemented as a set of system components
that allow IPX client or server applications to locate and communicate with
their IPX counterparts without IPX packets being visible on the wire.
Compatibility Mode components translate SAP advertise and query requests
into their SLP equivalents, allowing IPX applications to dynamically
advertise and/or discover without generating IPX traffic on the wire.
All NDPS components are IP-aware and IPX-aware, so they do not rely on
Compatibility Mode to implement IP-based communication.
When Will Clients Be Upgraded?
If you have a fairly large number of workstation clients, you might find it
inconvenient to try to upgrade them to NDPS all at once. Because NDPS
allows you to implement all of the server management components while
allowing your workstation users to continue to print to queues just as they
always have, you can upgrade these clients at a pace that suits your needs
while you take advantage of the management benefits NDPS provides
immediately. See “Making the Transition Gradually” on page 41 for more
information.
How Much Network Security Will Be Needed?
NDPS is tightly integrated with eDirectory
TM
to maximize both the security
and ease-of-management that eDirectory provides. The level of security you
desire for each of your printers can be as flexible as you want it to be, ranging
from total public access to tightly controlled access. Printer security for
controlled access printers is ensured through the assignment of the Manager,
Operator, and User access control roles. For more information, see Chapter 7,
“Managing Printing Security,” on page 103.
How Will Brokered Services Be Distributed?
While the distribution of your Brokers is not a critical issue initially, you will
probably want to give some thought to this issue as you do your preliminary
planning. You will not need to create a Broker on all of your servers, but you
will want your Brokers sufficiently well distributed so that your brokered
services (Service Registry Service, Event Notification Service, and Resource
Management Service) will be readily available on the system when needed. As
you gain experience with your new system, you may want to add or delete
Brokers to optimize the efficiency of your system or to store your brokered
resources (maintained in the Resource Management database) where you want
them.
