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...
COLAN III is a control oriented LAN designed to achieve reasonable
network performance and flexibility at low cost. These objectives are
achieved by utilizing inexpensive microcontrollers (8031s) and hardware
support. The CSMA/CD network protocol with single bus structure has
been employed in COLAN III as an arbitration method to control...
The performance of multi-user workstations that access files
over a local area network is studied. Such file systems, called
distributed file systems, provide access of remote file systems with a
great degree of transparency. The main objectives are
To study the principles of distributed file systems. specifically
NFS from Sun...
A Hybrid Meshnet LAN, a new local area network architecture, has been proposed by Dr. Cheoul-Shin Kang and Dr. James Herzog. It provides for distributed control hybrid architecture which is good for effective load sharing under various local area network environments. Hybrid Meshnet has a dual channel structure, a token...
Routing from a single source node to multiple destination nodes using node disjoint paths (NDP) has many important applications in parallel systems. For example, if a source node wants to send distinct messages to distinct destination nodes, then the one-to-many NDP routing is useful.
Unlike parallel systems with shared-memory, each...
TASKMASTER is an experimental microcontroller node of a real-time control
oriented network which was proposed by James H. Herzog and Tinggui Zhang to
demonstrate the feasibility of a task oriented control structure in performing distributed
control actions. This study is a continuation of research involving the TASKMASTER
network.
A high...
Quotient rings of Gaussian and Eisenstein-Jacobi(EJ) integers can be deployed to construct interconnection networks with good topological properties. In this thesis, we propose deadlock-free deterministic and partially adaptive routing algorithms for hexagonal networks, one special class of EJ networks. Then we discuss higher dimensional Gaussian networks as an alternative to...
As broadband Internet becomes widely available, Peer-to-Peer (P2P) applications over the Internet are becoming increasingly popular. Such an example is a video multicast application in which, one source streams a video to a large number of destination nodes through an overlay multicast tree consisting of peers.
These overlay multicast-based applications,...
