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 ...

As data traffic increase rapidly, IP over WDM (Wavelength Division Multiplexing) transport will replace conventional SONET transport in current metropolitan area networks. Such networks will require new MAC protocols to efficiently share network bandwidth among multiple network nodes. This research project describes and evaluates a novel Carrier Sense Multiple Access with Idle Detection (CSMA/I...

Message sequencing and channel assignment are two important issues that need to be addressed when scheduling variable-length messages in a wavelength division multiplexing (WDM) network. Channel assignment addresses the problem of choosing an appropriate data channel via which a message is transmitted to a node. This problem has been addressed extensively in the literature. On the other hand, m...

The con uence of technical advances and multimedia service needs is intensifying the need for high throughput and low latency. Future communication networks will face an increase in tra c driven by multimedia requirements with stringent delay and jitter requirements. Wavelength Division Multiplexing (WDM) optical networks have the potential for meeting these goals by o ering unprecedented high ...

This report gives an overview of some of the protocol and networking design issues that have been addressed in Flamingo, a major ongoing project which investigates the use of WDM optical technology in local access networks. Quality of service delivery and wavelength assignment are focused on in this report. A brief introduction to optical networks and WDM as well as a brief description of Flami...

The perfomnce of a symmetric Robust WDM network that uses token-passing on the signaling channel and has a limited number of lasers per station is modeled and analyzed for circuit-switched connections. Robust WDM networks use a reservation interval during which all stations cease their WDM transmissions so that the station holding the token may establish a connection with its intended destinati...

An innovative overlapped-subcarrier multiplexing (O-SCM) technique is proposed for wavelengthdivision multiplexed (WDM) passive optical networks (PONs).Allowing a certain amount of spectral overlap between the uplink and the downlink maximizes the spectrum usage of bandwidth-limited reflective semiconductor optical amplifier (RSOA)-based optical network units (ONUs), while reducing the effect o...

Optical access, or Fiber-To-The-Home (FTTH), has long been considered a final solution to the problem of upgrading the current bottlenecked access to the one capable of delivering future broadband, integratedservices. The high cost of large-scale deployment of fiber and optical network systems in the field under traditional point-to-point architecture, however, is a major economic barrier to th...
