	FIVE NEW NETWORKING PRODUCTS FROM SUN EXPANDS INDUSTRY'S
		BROADEST LINE FOR OPEN NETWORK COMPUTING
 
 
MOUNTAIN VIEW, Calif. --October 2, 1989-- Sun Microsystems today
introduced five new products for its networking line, giving it the
most comprehensive, open networking solution of any system vendor.  The
new products expand upon Sun's existing offerings, reaffirming Sun's
long-time commitment to distributed workgroup computing based on
industry standards.

The new products--part of SunNet(TM), Sun's new designation for its
comprehensive suite of networking products--include powerful new
network management packages, along with products that further enhance
high-performance connectivity, including a new controller that links
Sun workstations to fiber distributed data interface (FDDI) networks.

The new products include:

  SunNet Manager, which offers the industry's richest network
management solution for distributed workgroups that use the TCP/IP
communication protocol.  TCP/IP-based systems represent by far the
largest installed base of any open networking protocol.  SunNet Manager
is a multi-function package for managing network resources, from
computers and bridges to network applications and services.  It keeps
track of how network resources are functioning, alerting users to any
failures or potential failures.  The product is "extensible",
permitting users to easily add new network devices, protocols or tools
to the SunNet Manager framework.

  SunNet License, a software license management package that offers an
unprecedented combination of flexibility, scalability and ease of use
for license management across a network.  SunNet License allows
"concurrent usage" licensing methods, under which software licenses
"float" between multiple users.  This contrasts with today's typical
licensing arrangements, which require a company to buy an individual
license for every user who requires access to a given software
package.  Software vendors will benefit from the package's support of
multiple licensing methods and security features.

  The FDDI/Dual Attach Controller, called FDDI/DX(TM), is a VME board
that lets Sun users take advantage of the large capacity, fault
recovery and increased security features of the FDDI network standard.
Sun is one of the first system vendors offering an FDDI product.

  SunLink(TM) Channel Gateway, the first complete hardware and software
solution for connecting Sun workstations to IBM mainframes.  It allows
Sun computers and IBM System 370-compatible mainframes to exchange
files and messages as well as to submit jobs and commands, using the
IBM NJE protocol.

  High-speed Serial Interface (HSI) is a VME board product that allows
Sun networks to utilize high-speed transmission lines such as T1 and
CEPT for simple, cost-effective interconnection of Sun networks.

SunNet Based on Standards

SunNet includes a wealth of products built upon industry standards,
such as TCP/IP, Ethernet, X.25 and others. In addition, SunNet offers
users a migration path to emerging standards like FDDI and OSI.
Included in the SunNet family are the SunLink products, which allow
connectivity with IBM and DEC systems and PCs.  At the heart of the
SunNet line is a group of products called Open Network Computing
(ONC(TM)), a platform for the development of distributed applications.
A variety of network services run on this platform, such as Sun's de
facto industry standard Network File System (NFS(TM)), licensed by more
than 260 organizations worldwide.  Another group of products in the
SunNet line are the just-introduced packages for network management.

Together, SunNet products allow distributed workgroup networks to be
built out of mixed-vendor, geographically separated computing
resources.  "SunNet is similar in breadth to the networking solutions
of companies many times larger than Sun," said Larry Garlick, vice
president of distributed systems.  "The new products raise the ante for
vendors wishing to compete as suppliers of distributed computing
solutions."

Unlike vendors of proprietary products, Sun's strategy is to leverage a
company's existing computer resources by connecting these systems to
innovative new products while migrating to industry standards.  "This
gives users the freedom to incorporate other vendors' equipment and
technologies into their networks," said Garlick.

Sun Microsystems, Inc., headquartered in Mountain View, Calif., is a
leading worldwide supplier of network-based distributed computing
systems, including professional workstations, servers and UNIX
operating system and productivity software.
