Christian Rovsing is Denmark's fastest growing, high
technology computer and aerospace electronics company.
Founded in 1963 the company currently employes approximately
600 people, of which over 50% are professional engineers
and technologists.
In the more recent years the company has experienced
a rapid growth rate approaching 30% annually, and it
is expected that the company will have a business volume
of approx. 50 million Dollars in 1981.
The basis for the success of the company is its advanced
"CR80" computer which forms part of most systems designed
by Christian Rovsing.
The company is engaged in design and supply of telecommunications
systems and networks for military and commercial applications,
and in most cases the new packet switching schemes
are designed to be inherent in the systems. Furthermore,
cryptographic encoding/decoding techniques are being
used for purposes of system security and network partitioning
requirements.
The company is heavily engaged in defence computer
communications activities and has supplied a number
sophisticated digital switching systems for NATO in
recent years.
Christian Rovsing is participating as a major supplier
to the European space program and also supplies the
Fire Control Computer for the F-16 fighter aircraft,
which is being manufactured under contract for DELCO
ELECTRONICS INC.
Understandably, all military oriented systems undergo
rigorous stress tests and security checkouts, and Christian
Rovsing is accustomed to perform well under such stringent
guidelines.
The company's management and technical teams have developed
the necessary diciplines to meet their commitments
timely and efficiently.
Christian Rovsing jointly with CNCP Telecommunications,
herewith offer to Air Canada their combined technical
expertise and management knowhow, for the successful
supply, implementation and service support of Air Canada's
new data network.
Please find below an excerpt of a letter received from
CNCP, which supports the spirit of cooperation between
Christian Rovsing and CNCP, expressed above.
EXECUTIVE SUMMARY INSERT
EXECUTIVE SUMMARY INSERT CONT'D
T̲E̲C̲H̲N̲I̲C̲A̲L̲ ̲S̲U̲M̲M̲A̲R̲Y̲
Christian Rovsing's technical team has thoroughly reviewed
Air Canada's Request for Proposal (AC2001), and we
fully understand Air Canada's desire to establish initially
a backbone network with the capability for expansion
of some with several high speed host computer interfaces,
and a large number of terminal multiplexers and access
networks, connecting 40.000 - 50.000 terminals by 1991.
The system proposed fully meets these needs. Also considerations
are given to flexibility of the network such, that
if Air Canada's business needs change, the network
can accommodate these needs for open-ended growth.
The system as proposed can accommodate horizontal expansion
on a modular basis without the risk of major system
modules (CPU) to become outdated and subject to replacement
.
The following requirements have guided our system design:
o Open Ended Growth
o Short and Guaranteed Response Times
o Little spread of Response Time
o Ultra High Systems Availability
o Ease of Maintenance
o Graceful Evolution
o Network Interfaces evolution
o Transmission Media Compatibility
o Selective Flow Control/Prioritizing
o Flexibility
o Standard/Consistent Interfaces
o Network Management and Control
o Use of developed modules to guarantee delivery.
The proposed network, the Backbone Network Configuration,
represents a cost effective solution to the present
network needs at Air Canada with full expansion possibilities
for the future. The Backbone Network Configuration
reflects the desired partitioning described in the
RFP. There are initially:
- Two nodes
- a Gateway
- a Network Management Host, and
- an Electronic Mail Host.
The Network Control Centre will be dualised, i.e. there
will be one in each of two nodes.
Figure II 3.2-1…01…Backbone Network Configuration
Communications software for the Backbone Network Configuration
is based on the Open Systems Interconnect principle,
and the following protocols are used:
- X.25: DTE interface to the Node
- X.121: numbering plan
This allows the proposed network to provide the following
levels of service:
- Packet switching (CCITT's X.25)
- Virtual protocols
- interactive terminals
- file transfer
Virtual protocols allow a unified Host Access Concept
and a Unified Terminal Accept Concept to be carried
out.
The system can support the following:
- Interactive traffic
- Protected message switching (guaranteed delivery)
- printer traffic
- Host-to-Host file transfer
Our most important results of system design is ensurance
of a graceful change over from the present ACNC system
to the new backbone network by implementation of a
GATEWAY.
System implementation is based on a proven fault tolerant
computing system, the CR80. The CR80 is well suited
to be used in the Packet Switching Network due to its
architecture - shown in the following diagram - with
distributed processing, multiple bus structure, and
modular construction. Modular construction is found
at every level of hardware from interchangeable printed
circuit boards to identical processor and channel units.
Virtually openended growth will be possible, based
on the software and hardware provided with the initial
system, and the following is a list of growth areas
with projected Air Canada 1991 maximums:
o packet switching capacity: 2400 packets/sec. Initial
system expansion by a factor of four. (12 processing
units - 1981 state of the art)
o subscriber capacity: 20,000/node (initial system
expansion by a factor of three).
o internodal message trunk capacity: 2 Mbits/sec.
(necessary to accomodate the Passenger Management
System and host to host links in the Host Access
Network)
o internodal megabit satellite links
o front end processor connections to host access
network
o videotex
o telefax
FIGURE…01……01…CR80 SYSTEM ARCHITECTURE
The growth areas mentioned above can be accomodated
by addition of existing modules and, therefore, illustrate
the expandability of the proposed system.
The ACDN through-put will meet the present requirements,
the requirements for 1985, and the projected requirements
for 1991.
The minimum system, using one active processing unit
and one back-up processing unit, has a rated through-put
of 206 packets/sec. This rate is based on the theoretical
through-put maximum corrected for significant overhead
operations and a utilization factor of 70 %. .
The system for 1985 - the minimum system expanded by
a factor of three - will provide a rated throughput
of 618 packets/sec.
The system for 1991 can be expanded to handle up to
16 times the capacity of the minimum system, based
on the present supra bus data rate. This will allow
a switching capacity of greater than 3200 packets/sec,
which is a conservative estimate that does not take
into account expected improvements in bus capacity
or processing unit power. System expansion is illustrated
in the following diagram.
The Data Network software is highly modular in nature.
All communication software levels conform to international
standards. Apart from standardized communication oriented
software, an extensive range of application functions
are included. These provide the operational staff with
facilities for network-traffic and subscriber data
management along with powerful facilities for statistical
data processing that allow network tuning and subscriber
profile evaluation.
The packet switching network will account for only
a small part of the total sender-receiver response
time. In 85% of the cases, approximately 500 ms will
be used by the packet switching network for message
transmission (with a 70% utilization factor); the overall
sender-receiver response time allowed for 85% of messages
is 2.5 seconds.
An extremely high level of reliable service can be
provided to each individual subscriber and also to
groups of subscribers. Even if a group of subscribers
exceeds the capacity of a single processing unit -
the equivalent of more than 130 links - the fault tolerant
system has enough capacity to continue functioning
after one failure. Actual experience shows that the
proposed system has a monthly downline time that is
only half the RFP acceptable value.
Last, but not at all least, the Air Canada Switching
Network will be fully supported by the Integrated Logistics
Support Departments of Christian Rovsing and CNCP.
The following key items will be provided in compliance
with the tender requirements:
- transportation (Christian Rovsing)
- installation (CNCP)
- on-site test facilities (Christian Rovsing)
- complete documentation (Christian Rovsing)
- customer training (Christian Rovsing)
- maintenance (CNCP)
- support (Christian Rovsing)
- spare parts program (Christian Rovsing)
The decision to bid the Air Canada Packet Switching
Network represents a definite commitment on the part
of Christian Rovsing to devote its resources and technological
talent to ensure successful implementation of the system
in Canada.
For the last three years, a devoted effort at Christian
Rovsing has been made in the field of network communication.
The company has implemented the following programs:
o FIKS - an integrated defense communications network
with message switching and data transfer for the
Danish Department of Defense.
o CAMPS - a computer aided message processing system
to prepare, dispatch and receive messages for NATO.
o LMENET - a private data communication network for
L.M. Ericsson.
Along with the technical know-how acquired through
these projects, Christian Rovsing have gained significant
experience in project management, and we pride ourselves
on our ability to meet the time and financial demands
of large projects.
This participation represents a deliberate desire by
the company to participate in this specialized area
of high technology.
