Several optical interconnect architectures inside data centers (DCs) have been proposed to
efficiently handle the rapidly growing traffic demand. However, not many works have tackled …

In this paper, we present a distributed medium access control (MAC) protocol and a network
architecture suitable for optical intra-rack data center networks (DCNs). The intra-rack …

A dual media access control (DMAC) based hierarchical optical access network (HOAN) is
proposed for data center networks, consisting of passive optical distribution modules …

We introduce physical-layer network coding (PLNC) technique in a passive optical
interconnect (POI) architecture for datacenter networks. The implementation of the PLNC in …

High-performance scalable data centers call for huge-capacity optical packet switches and
QoS (quality-of-service) guaranteed multistage switching, where reconfiguration overheads …

This paper presents the design of a software defined passive optical intra-rack network (SD-
POIRN) based on optical coupler fabric in data centers. The data plane of SD-POIRN is a …

We study traffic scheduling in optical-electrical switching fabrics in Data Center Networks
(DCNs) based on multi-stage Clos networks to minimize data transmission delay and ensure …

Due to the reconfiguration overhead of optical fabrics, batch scheduling method is generally
used to schedule an optical packet switch, with a necessary speedup inside the switch to …
