- Here's some "information about any developments in the future": specifically
- about 'Universal Networking from Acorn'. This was announced at BETT, and a
- brochure has been available free from your Acorn network dealer ever since;
- its product code is APP 420. To quote from the brochure:
-
-
- "Acorn and Networking
- --------------------
-
- The ability for IT users to be able to communicate with each other and with
- other companies is now recognized as one of the key factors governing the
- success of enterprises as diverse as commercial multi-nationals and village
- schools.
-
- Acorn's commitment to communication in the truest sense is nowhere better
- shown than in its strategy for the 90s, the Universal Networking System from
- Acorn.
-
- The Acorn Universal Networking (AUN) System enables users of AUN to have a
- mixture of operating systems, machines and cabling types co-existing on the
- same network. Regardless of which, the users' and manager's interface and
- access to resources remains a consistent one.
-
- The use of Industry Standard protocols is at the heart of Universal
- Networking and it is this that enables different systems to co-exist on a
- network.
-
- Universal Networking Systems allows a choice of technologies and a choice of
- prices and performance. Investment in existing equipment can be maintained
- whilst the number of users on the network can be increased on a step-by-step
- basis, as required and as budgets allow.
-
- Acorn protects your IT investments with no need for expensive retraining or
- software upgrades. No longer will users be faced with expensive upgrades of
- their whole system as the only way to keep pace with technology. No longer
- will users have to make painful choices between incompatible systems with
- mutually exclusive benefits.
-
- As much or as little new hardware as you please can be added at a rate to
- suit your needs. This modular approach allows you to continue using and
- benefitting from your existing IT investment; whilst the 'Open Systems'
- approach of AUN enables you to benefit more quickly from enhanced IT
- technologies that will now work alongside your existing equipment. Users
- also benefit from this investment more quickly as their interface to the
- network and its resources remains familiar."
-
-
- The brochure then goes on to give an example of developing an existing
- 'cluster network' (ie Econet with Level 4 FileServer). A second Ethernet
- network is added to form a 'departmental network'. The Econet and Ethernet
- are interconnected using a Level 4 FileServer fitted with both types of
- interface, and running AUN software: an AUN 'gateway station'. It says:
-
-
- "The advantage for the network manager in Universal Networking from Acorn is
- that the software in the gateway computers handles the routing issues
- intelligently and without supervision. Combined with the capability of
- managing the whole system from a single station, this frees the manager from
- some of the day-to-day burden, and allows him to concentrate on the
- important issues of IT development."
-
-
- The brochure then continues the example, showing the further expansion of
- the network to form an 'enterprise network'. The back page goes on to give
- more details:

- "Future Directions
- -----------------
-
- IT users worldwide have been demanding that vendors show support for the
- concept of 'Open Systems', particularly in the area of networking. Briefly,
- the idea behind Open Systems is that customers should be able to use any
- hardware or software without consideration of 'compatibility'. Obviously,
- this ideal is still some years off, but by endorsing Open Systems as they
- apply to networks, Acorn Computers will be in a position to ensure its
- customers that their networks will be able to participate in the future of
- networking.
-
- Acorn endorses the Open Systems approach to networking which has come
- together in the 7-layer reference model published by the International
- Standards Organisation (ISO). This model provides the concepts needed to
- build 'open' networks. Those manufacturers that describe their solution
- using proprietary technology will find it very difficult to make systems and
- networks that work together. In a situation where there is a requirement for
- products to work together and communicate with the outside world it is
- likely that a single vendor solution will prove untenable.
-
- By applying the OSI reference model Acorn ensures that users can interwork
- with other networks and systems. This enables our systems to interwork with
- other systems in the same network, thus allowing users to choose the
- solution that best fits their requirements without being isolated by this
- choice.
-
- Protocols are the languages of networking. Acorn's Universal Networking
- System (AUN) is based on the industry standard TCP/IP protocols. Acorn's use
- of TCP/IP and other non-propietary standards ensures thst users are able to
- have the benefit of a system that is built specifically to meet their needs.
- Acorn's Universal Networking allows you to invest with confidence in the
- present whilst ensuring that you have a networking infrastructure that can
- incorporate your future requirements.
-
- Such an example could be a site which decides to replace Econet with
- Ethernet. AUN will allow for the simple replacement of the underlying cable
- without disruption to the users. From the users' viewpoint his world remains
- unchanged so skills and training do not require re-learning and the benefits
- of enhanced technology can be immediately realised. Further cabling types
- such as fibre optics (FDDI) and cordless LANs (CLANs) can be accomodated as
- required.
-
- Universal Netwroking ensures that any computer which can support TCP/IP
- and/or Ethernet will be able to connect to an Ethernet network within AUN.
- This includes PCs, Apple and Unix-based systems. This has the advantage of
- allowing the user to retain the friendly and powerful RISC OS environment,
- whilst making full use of other systems on your network. This way of working
- is particularly common in universities and larger commercial organisations,
- where TCP/IP and Ethernet are widely used to connect a diverse collection of
- resources to the user's desk.
-
- By endorsing TCP/IP and moving towards full ISO standards, Acorn is showing
- its continuing commitment to providing its customers with the best available
- standards, that are internationally supported, at any given time. Acorn
- Computer's customers are thus able to build networks now, that will be able
- to incorporate additional technological benefits as they are developed or
- become economically available."
-
-
- The brochure then goes on to address issues of support, and to give a
- glossary.
-
-
- I hope you find useful this information about the direction in which Acorn
- is going.
