and number of teleprocessing networks as well as broadened their scope and complexity. This added size and complexity has magn$ed the need for communications network management. One approach to communications network management is to provide centralized control which is integrated into the Systems Network Architecture user network. This approach is described in this paper by focusing on two pro...

This document provides detailed call flows for the scenarios documented in the Framework for Centralized Conferencing (XCON) (RFC 5239) and in the XCON scenarios (RFC 4597). The call flows document the use of the interface between a conference control client and a conference control server using the Centralized Conferencing Manipulation Protocol (CCMP) (RFC 6503). The objective is to provide de...

Computational complexity results are obtained for decentralized discrete-event system problems. These results generalize the earlier work of Tsitsiklis, who showed that for centralized supervisory control problems (under partial observation), solution existence is decidable in polynomial time for a special type of problem but becomes computationally intractable for the general class. As in the ...

Ethernet Passive Optical Network (EPON), an access network technology, has drawn considerable research attention in recent years. EPON can be implemented in centralized or decentralized architecture in the access network. Most of the researches were focused on the centralized architecture, where bandwidth allocation decisions for Optical Network Units (ONUs) are made by distant Optical Line Ter...

In the context of energy consumption reduction, this paper focuses on the application of Model Predictive Control to occupants’ thermal comfort together with indoor air quality control while improving the whole building energy efficiency. First, an open-space office split in three zones, located in Cork Institute of Technology, is modeled. A centralized MPC is designed to control the temperatur...
