Integrated network and service management for the NCIH

To support the North Carolina Information Highway network and its services, GTE has developed new capabilities for the integrated management of broadband networks. These include: functionally integrated network management, enabling GTE to monitor and control ATM, SONET, and other related networks in real time, these capabilities are provided by the TelOps Network Integrated Control System (TONICS); and automated service management, enabling GTE to provide service-level configuration and fault management for new broadband services, these capabilities are provided by the broadband service management system (BSMS). Together, TONICS and BSMS provide a complete and integrated solution for managing broadband networks such as the NCIH     

Protocols for optical star-coupler network using WDM: performanceand complexity study

The efficiency of protocols coordinating the data transmission between the transmitter and receivers in a network of stations connected using a passive star coupler, equipped with fixed transmitters and tunable receivers, and using wavelength-division multiplexing is discussed. Two reservation-based protocols with varying degrees of signaling complexity are proposed: the dynamic allocation scheme (DAS), which dynamically assigns slots on a packet-by-packet basis, and the hybrid time-division-multiplexing (TDM) scheme (HTDM), which combines the TDM and the DAS scheme and allows both preassigned and dynamic slot assignment. Analytical results are derived for the delay performance of the two schemes and compared with that of TDM. It is shown that the performance of DAS under ideal conditions is close to optimal, but its signaling costs are exorbitantly high. On the other hand, HTDM has lower signaling needs, but has higher delays when compared to DAS
