The continuous growth of the Internet might turn network power consumption into a major issue. There is a huge potential for decreasing future Internet energy requirements by synchronizing the operation of routers and scheduling traffic in advance, thus reducing complexity - e.g., header processing, buffer size, switching fabric speedup and memory access bandwidth speedup. Moreover, a lower complexity...
This work addresses the high-rate session scheduling problem in fractional lambda switching (FlambdaS) networks. With its global phase synchronization and pipeline forwarding (PF) operation, FlambdaS offers promising network performance and scalability over its competitors, e.g., time division multiplexing (such as SONET/SDH) and wavelength division multiplexing (WDM). Yet, Non-Immediate Forwarding...
Time-driven Switching (TDS) networks with non-immediate forwarding (NIF) provides scheduling flexibility and consequently, reduces the blocking probability (blocking is defined to take place when transmission capacity is available, but without a feasible schedule). However, it has been shown that with NIF scheduling complexity may grow exponentially. Efficiently finding a schedule from an exponential...
As traffic on the Internet continues to grow exponentially, there is a real need to solve transmission and switching scalability. Moreover, future Internet traffic will be dominated by streaming media flows, such as video-telephony, video-conferencing, 3D video, virtual reality, and many more. Consequently, network solutions will need to offer quality of service and traffic engineering together with...
Fractional lambda switching (Flambda;S) is a novel proposal for the management of all-optical networks with sub-wavelength provisioning capability. The unique characteristic of Flambda;S is the utilization of the UTC (coordinated universal time) for alignment and switching. Several central research issues are still open in Flambda;S and need to be formally defined and analyzed. Within the scope of...
