International audienceWe propose a new receiver architecture for coherent detection in slotted optical packet switching rings with elastic (rate adaptive) optical transponders. Such rings are a candidate solution for future datacenter and metropolitan networks. The new receiver can detect more than a single packet per time slot and consequently has higher flexibility (translating into higher supported capacity, or, equivalently, lower end-to-end latency, or a combination or both), at the cost of a moderate increase in the transponder complexity and energyconsumption (less than 10%). We apply network plan- ning and traffic engineering simulation tools (which we validate on small examples using theoretical models) to quantify the increase in network capacity and latency reduction that can be achieved thanks to the use of the new receivers. Finally, we identify the stability problem of the insertion process in the rings with the coherentreceivers, and propose a polynomial network planning algorithm, for the case of fast-tunable transmitters. We evaluate the cost of enforcing the stability, in terms of the additional transponders needed, for the mentioned case

Metro networks support increasing traffic volumes and evolving traffic profiles. Revisiting metro network architecture, optical packet rings with packet optical add and drop multiplexing (POADM) features are proposed in order to support both optical transparency and subwavelength granularity. A medium access control (MAC) structure for multiring POADM networks is proposed, which can support multiprotocol encapsulation and provides the support of differentiated quality of service (QoS) and differentiated protection on a per-flow basis. Unicast and multicast flows are efficiently transported between stations, with a lightweight control within each station. An opportunistic insertion process associated with an appropriate scheduling process is shown to ensure transport network QoS levels. Simple models are provided to assess the transfer performance on the POADM ring. Per-flow protection mechanisms are proposed, and their efficiency is assessed. Dimensioning costs are derived, which take into account the number of used wavelengths and the number of fixed receivers required to support a given traffic matrix. Finally, it is shown that POADM rings can be used to directly support metro Ethernet services and thus allow collapsing the stack of transport network layers.
