This paper presents an overview of a distributed programming language called DMODULA,which is intended for the programming in a distributed environment. DMODULA develops module concepts of its ancestor,MODULA-2,and provides features of generic and remote procedure calls.DMODULA has been implemented on the ZOZ system,a distributed microcomputer system consisting of several LSI-11 microcomputers,which was designed and implemented at Nanjing University in 1982.

Design of a general purpose graphics system in a computer network environment requires that the architectural design of the graphics system be suited to such an environment and the advantages of the network environment be taken for distributed graphics processing and the sharing of resources. An architectural model is designed to meet these requirements. The model is characterised by the distribution on the machines in the network of graphics facilities provided by several graphics subsystems with various c…

An efficient method for simplifying a multivalued SULM network is presented in this aper.This method employs a cascade decomposition on a multivalued sequential machine M. At first we decompose M into two simpler machines M/π and M′.Instead of the traditional normal tree type network,a simpler SULM network that can realize M can be constructed by cascading M/π and M′.

The distribution of station locations in a CSMA network can have significant effect on network throughput. In this paper, we develop an analytic model for unslotted, non-persistent CSMA bus network where the stations are uniformly distributed along the bus. We derive a closod form expression for throughput approximation, and discuss the fairness of CSMA protocol using the bus topology. Analytic and simulation results are presented and compared.

This paper presents the design and implementation of a message-based distributed operating system kernel NDOS. The main purpose of the kernel is to support a distributed data processing system and a distributed DBMS. It uses the abstraction of communication between processes as basic mechanism. In NDOS, services and facilities such as message passing and process synchronization, which are related to IPC and may cause the change of the state of a process, are integrated into a single concept, an event.

The connectivity of a strongly connected network may be destroyed after link damage.Since many net- works are connected by directed links,the reachability may be restored by altering the direction of one or more of the links and thus reconfigoring the network.The location of the failed link must first be determined.In this paper,we examine new methods to determine the location of failed links and nodes in networks.A routing test approach is proposed and the conditions under which communication networks may …

For networks that are directed or can be represented by a directed network,reversing one or more of the uni-directional links may provide the ability to reconnect a network that has been disconnected by link failure, In this paper,a new approach to reconfigure such networks is proposed.We develop a linear time algorithm which,when reachability has been destroyed by the removal of a single link,optimally restores teachability through the reversal of selected links.Multi-link failure reconnectability is discu…

It is desirable in a distributed system to have the system load balanced evenly among the nodes so that the mean job response time is minimized. In this paper, we present.a dynamic load balancing mechanism (DLB). It adopts a centralized approach and is network topology independent. The DLB mechanism employs a set of thresholds which are automatically adjusted as the system load changes. lt also provides a simple mechanism for the system to switch between periodic and instantaneous load balancing policies wi…

In the design, the key problem is how to find some efficient heuristic algorithms. To solve this problem, a nonliner- discrete-capacity assignment heuristic and a hybrid perturbation heuristic are suggested. Then, a practical CAD system which helps design the topology of network will be introduced.

In this paper, the normalized exponential neural network (ENN) is studied. It is proved that ENN is a universal approximator. The stability relation between systems and neural networks working as controllers is investigated. The results show that when designing a system, one should firstly consider system stability rather than controller stability. Accordingly, a new hybrid learning algorithm is presented, and it is proved that this algorithm eventually converge to equilibria.

This paper proposes a new approach for implementing fast multicast on multistage interconnection networks (MINs) with multi-head worms. For an MIN with n stages of k×k switches, a single multi-head worm can cover an arbitrary set of destinations with a single communication start-up. Compared with schemes using unicast messages, this approach reduces multicast latency significantly and performs better than multi-destination worms.

So in order to undertake the tasks in admirable pro portions, they have to adjust their undertaking tasks only by self-learning. In this paper, the performance of this syste…

Amodel-driven simulation-based method is then proposed for the computation of meanline delay in a network design. Both the hybrid-FGN and the FARIMA algorithmshave been used to synthesize self-similar sample paths. The comparison results withreal-traffic data sets firmly establish the usefulness of the proposed model-drivensimulation-based method. A practica…
