Switching and error recovery in terabit ATM networksSabaa, Amr Gaber 15 November 2017 (has links)
This thesis addresses two of the main issues required to build reliable terabit ATM networks.
A high-capacity switch and an efficient error recovery protocol are the key elements
in building a reliable terabit ATM network. In this thesis, a terabit switch architecture and
a reliable end-to-end error recovery protocol for terabit networks are introduced.
The proposed terabit ATM switch architecture is designed to work efficiently in low-capacity
and high-capacity environments. The architecture is developed by interconnecting
small-capacity switching modules in a scalable fashion. The switching module can be used
alone as a small-capacity ATM switch. Multiple the switching modules can be used to
achieve any required switching capacity. The proposed interconnecting scheme provides remarkable
low cell-delay characteristics with a simple distributed cell scheduler. The proposed
architecture has a high reliability: Even when a complete switching module fails the
switch will continue to work efficiently.
The switching element which is introduced as the main building block for the terabit
switch architecture is a nonblocking input buffer ATM switch. The input buffers are implemented
as groups of parallel shift-registers. The parallel nature of the storing buffers overcomes
the Head Of Line and low throughput problems of existing input buffer switch architectures.
In addition, using the shift registers overcomes the need for serial-to-parallel
and parallel-to-serial format conversions.
ATM networks support different types of services having different delay and loss requirements.
A priority scheduling scheme is proposed to facilitate the support of different
Qualities of Service. The proposed scheme satisfies both real-time and non-real-time service
requirements.
Cell loss is not acceptable for some data applications. This thesis proposes an efficient error recovery protocol which guarantees reliable communication with limited overhead.
The proposed protocol requires a low number of control packets to achieve reliable communication.
It also adapts itself, in order to work efficiently during both congested and non congested
states. / Graduate

REMOTE CONTROL OF TWO AXIS AUTO-TRACKING TELEMETRY ANTENNASCronauer, Tom, Eslinger, Brian 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Due to Cost and Safety considerations the Range Division of the 412th Test Wing is
upgrading remote telemetry (TM) antenna sites to be operated and monitored remotely.
This is possible, in part, due to the installation of fiber optic cable, and the use of ATM
communications protocol. Both of these applications significantly reduce signal latency
from the remote control station located at Ridley Mission Control Center (RMCC) and the
Antenna site. This paper discusses the challenges associated with controlling these
sophisticated systems remotely. We will also describe the decisions and how they were
made, the concerns over system performance, and the impact to other systems. This paper
also addresses the technologies chosen to support the requirements and overcome the
challenges. The benefits of remote range sensors are also discussed. We will provide top-level
block diagrams of the system architecture.

A New Framework for Classification and Comparative Study of Congestion Control Schemes of ATM NetworksChandra, Umesh, 1971- 05 1900 (has links)
In our work, we have proposed a new framework for the classification and comparative study of ATM congestion control schemes. The different aspects on which we have classified the algorithms are control theoretic approach, action and congestion notification. These three aspects present of the classification present a coherent framework on which congestion control algorithms are to be classified. Such a classification will also help in developing new algorithms.
