| description | Nowadays, optical communication is widely employed by telecommunication
providers in the whole world due to its ability to support high bit rate applications. The
urge to provide end-to-end fibre connectivity arises to overcome the bottleneck problem
that occurs when packets are transmitted on the slower speed medium such as copper. In
optical transmission, bandwidth utilisation can be improved further by using multiple
wavelengths or channels in a single fibre.
This thesis discusses the implementation of multiple wavelengths technique for
Local Area Network (LAN) environment. It proposes a new Ethernet-based protocol that
uses multiple wavelengths for transmission, which runs on a single fibre. Ethernet/IEEE
802.3 is chosen because of its widespread employment in today's network and the
ability of extending the transmission rate up to gigabit transmission. Even though light
does not collide with each other, receiver contention might occur if more than one signal
arrives at the receiver at the same time. Therefore, some arbitration mechanism is
needed to synchronise the transmission and the tuning time of the respective transmitter and receiver. The proposed design is based on the physical bus topology with n number
of connected nodes and m number of operating wavelengths. All nodes are able to listen
to all wavelengths. A fast control unit is used, which is responsible for packet
scheduling.
The packets are scheduled based on a pre-computed time. Both transmitter and
receiver will be asked to tune to the· allocated wavelength. The transmitter can start
transmitting and the receiver will start tuning at a specified time. Control packets are
used for handshaking purposes. The main operation is placed at the control unit so that
no added complexity is experienced by the receiver. Thus, this technique further reduces
the cost. A suitable range of channels is obtained from the result. The network
performance is evaluated against several design parameters by comparing the
performance of each channel. The result shows a significant improvement whereby the
throughput and efficiency are increased and average delay is minimised compared to the
conventional system. |
