   Sammanfattning : The incredible growth in processing power and switching capacity in high-performance computers and switches puts very high demands on the interconnection networks. This is recognized in particular in massively parallel processing and extreme switching architectures. The demands are such that new interconnection architectures must be considered. LÄS MER

3. 2. Passive Optical Top-of-Rack Interconnect for Data Center Networks

   Författare :Yuxin Cheng; Jiajia Chen; Lena Wosinska; Matteo Fiorani; Qiong Zhang; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical communications; data center interconnects; MAC protocol; dynamic bandwidth allocation.; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Optical networks offering ultra-high capacity and low energy consumption per bit are considered as a good option to handle the rapidly growing traffic volume inside data center (DCs). However, most of the optical interconnect architectures proposed for DCs so far are mainly focused on the aggregation/core tiers of the data center networks (DCNs), while relying on the conventional top-of-rack (ToR) electronic packet switches (EPS) in the access tier.
