Survivable architectures for time and wavelength division multiplexed passive optical networks
The increased network reach and customer base of next-generation time and wavelength division multiplexed PON (TWDM-PONs) have necessitated rapid fault detection and subsequent restoration of services to its users. However, direct application of existing solutions for conventional PONs to TWDMPONs is unsuitable as these schemes rely on the loss of signal (LOS) of upstream transmissions to trigg...
متن کاملDesign Principles for Multi-Hop Wavelength and Time Division Multiplexed Optical Passive Star Networks
Wavelength Division Multiplexing (WDM) has been shown to be one of the most promising ways to exploit the enormous bandwidth of a single mode optical ber. Networks employing WDM are commonly based on optical passive star couplers. The major cost and limitations of such networks lie in the interface (both transmitters and receivers) providing optical-electronic conversion between stations and co...
متن کاملRouting, Wavelength and Time-Slot Assignment in Time Division Multiplexed Wavelength-Routed Optical WDM Networks
This paper studies the routing and wavelength assignment problem for a circuit-switched time division multiplexed (TDM) wavelength-routed (WR) optical WDM network. In a conventional wavelength routed network, an entire wavelength is assigned to a given session (or circuit). This can lead to lower channel utilization when the individual sessions do not need the entire channel bandwidth. This pap...
متن کاملScheduling algorithm for differentiated service on wavelength-division-multiplexed passive optical access networks
Passive optical networks (PONs) will be the pervasive choice in the design of next-generation access networks. One possible solution to implementing passive optical access networks is to rely on wavelength-division multiplexing (WDM). Here we investigate the problem of providing real-time service to both hard and soft real-time messages in conjunction with a conventional best-effort service in ...
متن کاملA Media-Access Protocol for Time- and Wavelength-Division Multiplexed Passive Star Networks
A new media access protocol is presented for time and wavelength division multiplexed optical passive star networks. The protocol is based on a new \Bus-Mesh" virtual topology. The network provides minimum latency and high throughput while requiring only a single xed wavelength transmitter and receiver at each station. The use of non-agile, xed wavelength devices, readily available with current...
