This paper describes the design and implementation of
"A multiprocessor node for communication and control"
(MPCC). MPCC is a high speed, high performance local area
network capable of performing real time control tasks. This
is achieved by the concurrent operation of two 8051
microcontrollers, a dual port RAM and the...
Rapid advances in technology have seen computing move from a
large central computer to desktop microcomputers.
This advance was also
seen in the design of dedicated computers, computers designed to perform a
few specialized tasks or duties.
These computers, or microcontrollers, are
often controlled by a central computer and themselves...
This paper describes the design and implementation of
COLAN V, a High Performance Local Area Network for
Communications and Control utilizing a Communications Coprocessor.
The main objective of this thesis is to improve upon
the performance of previous COLANs in speed, switching
techniques and error detection techniques. This was
possible...
EDLAN is a simple, inexpensive local area network suitable for
educational applications. In EDLAN, a number of personal computers are
connected through an RS-485 global bus which carries the data
transmission among the computers. CSMA/CD protocol is used to control
the access of the global bus. The communications are controlled...
This thesis discusses the design and development of a
viable local area network (LAN) which supports both
communications and control applications. The emphasis was
to develop a practical and cost effective system which
offered high performance while utilizing low cost
components. System cost was kept low by utilizing a
twisted-pair...
COLAN (Control Oriented Local Area Network ) is a
redesign of the Task-Master, a daisy-chain structure
distributed control system. COLAN is a simple bus structure
communication subnetwork intended for distributed control
applications. Low cost and simplicity are two main design
criteria. Point-to-point and broadcast communications are
possible. A packet switching...
This paper describes the design and implementation
of COLAN II, a control oriented local area network (LAN).
COLAN II employs a bus interconnection structure and
a token passing method to control the access to the bus.
Major emphasis of the work is on the system structure and
the software operating...
The Control-Oriented Local Area Network (COLAN) is a
distributed control system for a series of networked
microcontrollers, which has been under development at Oregon
State University since 1986. A reliable master controller, functioning
both as a task scheduler and as a network controller, is
required to allow users to perform...
Hybrid-Meshnet is a communication subnet architecture for local area networks (LANs) designed to achieve a high degree of network performance and flexibility. These objectives are achieved by utilizing a dual channel structure. A token ring is used for short or prioritized data transmissions. A complimentary mesh network with arbitrary data...
GEMS (Graphical Ethernet Monitoring System) is an
enhancement to the SU-PC/IP NETWATCH program, for the
graphical display and recording of computer network packets.
SU-PC/IP (Stanford University Personal Computer/Internet
Protocol) NETWATCH displays one line of information per
packet, including the packet type, IP addresses, packet
size, and protocol type, etc. This...
