Introduction
Networking provides the foundation for customers to access business-
critical enterprise-wide information. It also allows customers to share
computing resources to achieve a competitive advantage.
Your Target Customer
Target Customer Characteristics
Your target customers for HP networking solutions are primarily Fortune
1000 companies. These customers share the following characteristics:
o Have offices in different geographic locations
o View communication between different offices as being mission critical
o Need timely information to make business-critical decisions.
o Have multi-vendor environments
o Desire to move towards de facto and industry standards rather than
being locked into a single vendor
A good example of a potential Corporate Business System customer would
be a public service provider of telecommunications.
Networking Solution Components
Networking solutions for the high-end customer include:
o A network that uses accepted de facto and industry network
communications standards
o The ability to connect a large number of end-users working with
workstations, PCs, and terminals
o The seamless integration of systems into existing environments to
protect the customer's investment in computing
o Distributed computing
o An open network that will grow as the customer's needs grow for faster
speed and more processing power
o An ability to connect different E-mail systems
o Access to enterprise-wide information
What You Should Know About Networks
When you discuss HP network solutions with a customer, you should be
comfortable with networking terms and products. The following is a
partial list of areas you should be able to discuss with a high-end
customer.
o Industry and de facto networking standards (OSI, TCP/IP, SNA)
o Client/server and host/terminal computing
o Graphical user interfaces
o Integrating application software
o Networking interfaces
o Network security issues
o Network management
If you need to review networking terms and concepts, please refer to
the workbooks for the HP 9000 Series 800 (SR188) and HP 3000 (SR189).
In addition to the networking terms and concepts listed above, you
should also be familiar with the following new terms and products:
o IBM co-existence
o FDDI (Fiber Distributed Data Interface)
o SNMP (Simple Network Management Protocol)
o Messaging backbone
o DCE (Distributed Computing Environment)
IBM: Co-Existence
HP's IBM networking products provide the HP Corporate Business System
seamless integration into IBM environments. HP's IBM communications
offering provides the customer with the following capabilities:
o Interactive communications
o Batch communications
o Program-to-program communication
o Store-and-forward (E-mail) communications
o Connectivity links
With the power of the new HP Corporate Business System combined with
the robust HP-to-IBM communications product offering, HP is well
positioned as the number one vendor to offload your customer's mainframe
applications.
FDDI (Fiber Distributed Data Interface)
FDDI is an industry standard for high performance networks. FDDI runs at
100 megabits per second (Mbps) link speed, 10 times faster than the
current local area network protocols. The FDDI standard evolved as the
growth in distributed computing, processing power, and high throughput
applications created the need for a faster processing speed in local
area networks.
SNMP (Simple Network Management Protocol)
SNMP is a de facto standard for managing multi-vendor networks. The
explosion of multi-vendor computing environments has given network
managers the challenge of integrating and managing their networks
effectively. SNMP provides the solution for these customers.
Messaging Backbone
Multiple E-mail systems usually exist in most Fortune 1000 corporations.
Trying to connect these E-mail systems and keeping directories updated
are key concerns of MIS managers. Linking distributed sites with up-to-
date order data with EDI applications is also a concern.
HP's X.400 Messaging Backbone Network offers your customer a solution
to these problems. For example, it allows users of HP OpenMail to send
and receive messages of CC:Mail users residing on a PC LAN.
DCE (Distributed Computing Environment)
DCE is a set of services including remote procedure calls, a security
service, naming service, timing service, and a distributed file service,
all of which enable the creation of transparent distributed applications
in a multi-vendor environment.

1992 (Hard copy: PN5091-3821E CD ROM: PN5091-3820E).
Ask LAN Anders. . .
. . . About Token Rings
Dear LAN Anders,
My company in New York recently acquired a new startup in Dallas that
has an installed token ring network. I want to purchase and connect an
HP Corporate Business System without incurring the extra cost of
rewiring my new building or purchasing extra routers or bridges. By the
way, I foresee the information flow increasing rapidly at the Dallas
site. To make things even more complex, this startup company in Dallas
also needs to communicate with our HP system here at corporate
headquarters in New York. CAN HP MEET MY CONNECTIVITY NEEDS?
Signed,
Ronald Trump
Dear Ronald,
You can put your mind at rest. As you know HP has a very strong
802.3/Ethernet offering. HP has recently announced and has available
today a new native token-ring interface. This interface can connect
directly to your existing token-ring network, alleviating the need to
buy unnecessary equipment.
As for your performance requirements, HP's Token Ring offering
supports both 4 Mbps (over-shielded and unshielded twisted pair) and 16
Mbps (over-shielded twisted pair) link speed, creating a smooth growth
path.
And to meet your future speed requirements, HP supports FDDI, which
will run up to 100 Mbps! To access your enterprise-wide information,
HP's X.25 or extended LAN products (bridges and routers) could be just
the ticket. The following figure shows what your network could look
like.

. . . About Server to Server Environments
Dear LAN Anders,
I'm an HP sales rep. I've got a potential new account that if I win, my
commission could equal the California Lottery! The customer needs a
high-end system that must access enterprise-wide information on all
systems. The customer already has an installed base of DEC VAXs. Can the
new HP Corporate Business System fit into this environment?
Signed,
One Answer Away
Dear One Answer,
Have I got an answer for you: STANDARDS! HP is the leader in providing
industry standard networking. Industry standards, such as OSI and TCP/IP
solve large multi-vendor communication problems such as yours. HP
provides the following multi-vendor server-to-server products:
US GOSIP
------------------------------------------------------------------------
HP 3000 HP 9000/S800 Compliance
________________________________________________________________________
TCP/IP
Telenet Now Now
FTP Now Now
NCS Now Now
OSI
FTAM Now Now Y
OTS Now Now Y
X.400 Now Now Y
X.500 UI Now Y
________________________________________________________________________
Now = Available Now UI = Under Investigation Y = Yes
An example of when customers can benefit from standards is when they are
developing a messaging backbone to support distributed applications such
as E-Mail, EDI, and FAX. HP's messaging backbone consists of the X.400
and X.500 products, which are based on OSI standards. The X.400 products
offer multi-vendor messaging for HP 9000 and HP 3000 Corporate Business
Systems.
The HP 9000 Series 800 also offers X.500, which offers directory
services (similar to how a telephone book is used with your telephone).
HP has the most robust messaging backbone offering in the industry.
In addition, the HP 3000 has made significant enhancements to the TCP/IP
network transport with the MPE/iX, release 4.0. These additions include
support for Berkeley Sockets 4.3 and Domain Names. By supporting these
features, the HP 3000 Corporate Business System now offers the standard
networking features available on most systems running UNIX, further
strengthening the interoperability of HP systems in multi-vendor
environments. The enhancements also increase the number of TCP
connections, which allows the Corporate Business System to be used as
servers for a significantly larger number of clients. Finally,
performance improvements match the increasing power and performance of
the HP 3000 Corporate Business Systems.
. . . About End-User Access
Dear LAN Anders,
I've known for a long time all about HP's terminal connect strategy with
DTCs and MUXs. But now my company also has two other types of users, PC
users and workstation users. The accounting department, which uses PCs,
needs to interact with an accounting application on our high-end
business system server, as well as share peripherals and files. The
engineering work group has workstations on their desktops. They need to
access and share files on the high-end server. I have not yet made a
decision as to what type of network operating system to purchase. What
can HP offer to meet my needs?
Signed,
Stumped Power User
Dear Stumped,
HP offers a wide variety of PC integration products to give your PC
users the flexibility of choice, and the ability to use one of HP's
powerful high-end Corporate Business Systems as a server. HP offers the
following PC integration products.

For your workstation users, HP offers NFS, which is a de facto standard
for distributed file access and is widely implemented among UNIX
workstations. By offering NFS, HP provides your workstation users with
transparent access to files located on the HP Corporate Business
Systems. NFS is supported today on both the HP 3000 S/900 and HP 9000
S/800.
And to meet your end-users' future needs for trans-parent access to
distributed applications in a multi-vendor computing environment, HP is
committed to supporting the full suite of Open Software Foundation's DCE
services.
. . . About Network Management in a Multi-vendor Environment
Dear LAN Anders,
Help! My company recently implemented a just-in-time manufacturing
operation which relies upon multi-vendor computing systems for
enterprise-wide business-critical information. Needless to say, it's
crucial that the computing network is continuously working. Any down-
time will have a significant impact on our ability to meet our shipping
deadlines. Trying to manage all these different computing systems has
been a nightmare and has meant many long hours for my staff. To make
matters worse, my relentless (#!?*$) boss is on my back to reduce the
cost of my support staff. Can you help this tired network manager?
Signed,
Swamped Network Manager
Dear Swamped,
Hewlett-Packard's adherence to network management standards provides a
person like you with the ability to manage HP systems in a heterogeneous
environment. That means that you can concentrate your network management
expertise in one location, which translates into reduced operating
costs.
Today and in the future, HP will continue to support the de facto and
industry standards for multi-vendor network management: SNMP and
CMIS/CMIP.
HP systems incorporate the SMNP agent capability, which provides
network layered information (configuration, performance, fault
isolation, etc.) to a SNMP management station, such as HP's industry-
leading OpenView Network Management station.
What you need to do is select a computer vendor like HP that supports
industry standard network management solutions.
Here is an example of a just-in-time manufacturing site using HP's
OpenView Network Management Station to manage a multi-vendor network.

Competition
HP, IBM, and DEC all state that they provide open networking. But only
HP delivers today on that promise. And HP delivers that promise across
all system platforms.
By favoring an open system based on accepted standards, HP can offer
its customers more connectivity and the ability to work with a wide
range of multi-vendor systems.
IBM's Networking
IBM:competing against; IBM offers system connectivity through:
o Primarily, SNA networking (a proprietary de facto standard) and
o Secondarily, minimum compliance with standard protocols, such as
TCP/IP and OSI
IBM Strength:
o A huge installed base of SNA
IBM Weaknesses:
o Lack of multi-vendor support for AS/400 platform
o PC-Host integration on AS/400 and MVS (for example, Novell NetWare)
o Favor proprietary SNA solutions over open standards
DEC's Networking
DEC:competing againstDigital offers system connectivity through:
o DECnet Phase V (1987 to 1991 it never succeeded)
o Advantage Networks (a new strategy that supports DECnet Phase IV,
TCP/IP, and OSI)
DEC Strengths:
o DECnet Phase IV has a large installed base and is well respected.
o SNA connectivity has a broad range of functionality.
o Perceived as a networking leader
DEC Weaknesses:
o Inability to deliver on promises (for example, DECnet Phase V,
including OSI)
o PC-host integration (for example, weak Netware offering)
o Late in embracing TCP/IP (third-party products)
o Favors DECnet product line over standards-based networking
HP's Vision for the Future
HP is continuously striving to provide our commercial customers with a
more effective means of efficiently accessing and distributing
information across their enterprise-wide multi-vendor network.
HP's commitment in adhering to de facto and industry standards has built
a foundation for meeting our customers' networking challenges. HP is a
leader in supporting the growth of standards technologies, such as
X.400, X.500, and OSF/DCE.
With HP's offering of high-end systems and the increasing use of
high-bandwidth applications (image-based and multimedia), customers are
faced with the challenge of trying to meet their growing bandwidth
needs. HP will continue to meet your customers' future requirements by
supplying standards-based, high-bandwidth connectivity products, such as
FDDI and Frame Relay.
HP delivers more industry-standard networking today to deliver growth
tomorrow.
Summary
Networking provides the foundation for customers to access business-
critical enterprise-wide information. It also allows customers to share
computing resources to achieve a competitive advantage.
Your target customers for HP networking solutions are primarily
Fortune 1000 companies. This customer's success is dependent upon
communication between offices that are often in different parts of the
world.
When you discuss HP network solutions with a customer, you should be
comfortable with basic networking concepts. You should also be familiar
with HP networking solutions that are available now or will be available
