With the rapid development of cloud computing and emerging services, traffic in data center network is experiencing an explosive growth, which has brought a great challenge to the existing electrical data center networks. In order to take full advantage of the large bandwidth of optical interconnects, the optical and electrical hybrid data center network is proposed. However, there are still some...
The massive adoption of cloud-based services in data center lead to an exponential increasing in both the amount traffic and servers, which brings a great challenge to data center network (DCN). In this paper, MOSA: a modular all-optical switching architecture based on arrayed waveguide gratings (AWG) is proposed to address the issue. The modular design makes MOSA can expand up to millions of servers...
We design and experimentally demonstrate the first resource orchestration across DWDM optical transport, radio access networks (RANs) and cloud domains based on SDN. The orchestration enables agile service creation and optimized resource allocation.
With the advances in semiconductor and circuit integrated technologies, the number of IP cores that can be integrated on one chip is becoming larger and larger. The traditional bus interconnection method of System on Chip (SoC) cannot meet the performance requirements of the Multi Processor System on Chip (MPSoC). Network on Chip (NoC) has improved the interconnect performance of IP cores. However,...
Energy efficiency in cellular mobile radio networks has recently gained great interest in the research community. The development of more energy efficient hardware and software components aside, effect of different deployment strategies on energy efficiency are also studied in the literature. The latter mainly consist of optimizing the number and the location of different types of base stations in order...
In next generation optical access the integration with the distribution network will probably become much more pronounced than today with a focus on “Ethernet everywhere”. We have demonstrated a multi-layer control plane over a combined access and aggregation network. The implementation is based on modifying and adapting existing GMPLS protocols.
