Container-based Cloud Desktop Service

  • Carroll M.
  • Coss M.
  • Friedman B.
  • Hadzic I.
  • Woithe H.

We present the architecture and system implementation details of a virtual desktop service that is entirely based on LXC containers. Each desktop runs in its own container using unmodified software packages from a ``stock'' Linux distribution. The underlying host system has been modified to provide isolation similar to that of ...

An Enhanced Power Control Scheme for Dual Connectivity

  • Liu J.

In 3GPP LTE-Advanced Release-12, the feature of dual connectivity (DC) has been introduced to enhance small cell networks from the aspects of higher layer architecture and physical layer procedures, which can improve mobility robustness and per-user throughput as well as avoid frequent hard handover among small cells. To guarantee the ...

An Enhanced Coherent Joint Transmission Algorithm for Multi-Cell Downlink Transmission

  • Sun H.

Coherent joint transmission (CJT) algorithm has been extensively investigated in multi-cell cooperative downlink transmission due to its huge potential performance gains. Comparing with the existing CJT algorithm based on the multi-user eign-mode transmission, an enhanced CJT (eCJT) algorithm is proposed in this paper to further enhance the performance of cellular ...

  • Scavo G.
  • Stefano Traverso

With the advent of Over-The-Top content providers (OTTs), Internet Service Providers (ISPs) saw their portfolio of services shrink to the low margin role of data transporters. In order to counter this effect, some ISPs started to follow big OTTs like Facebook and Google in trying to turn their data into ...

Ray Tracing Analysis and Field Trials of 3D Beamforming in Real Deployments

  • Albrecht T.
  • Halbauer H.
  • Herzog G.
  • Hoek C.
  • Koppenborg J.

In this paper, the properties and capabilities of 3D beamforming in a real propagation scenario have been analyzed by ray tracing simulation and been compared with field measurements for this environment. Therefore, a real propagation scenario comprising line-of-sight (LOS) and non-LOS (NLOS) areas has been modeled and applied to a ...

Scalable Congestion Control Protocol for Bursty Flows in Data Center Networks

  • Hwang J.
  • Yoo J.

Nowadays, data centers are the key computing resource for providing many online services such as web search and cloud computing. These applications, however, frequently suffer from network congestion even under low average link utilization because of momentary bursts in their traffic patterns. Some existing solutions utilize the Explicit Congestion Notification ...

We experimentally demonstrate transmission over a novel multicore fiber with 9 cores arranged in 3 groups of 3 cores, such as strong coupling occurs within the groups and weak couplings between groups. We transmitted over 2000 km in a single group and 200 km when all cores are used. low-loss ...

Impact of transponders wake-up time on sleep-mode enabled translucent optical networks

  • Morea A.

A very promising energy-efficient strategy in core networks is to put unused transponders into a low-power idle state. However, the no-negligible wake-up time of the transponders may dramatically impact the network performance. We show through simulations that significant degradations on performance take place for long wake-up times for various traffic ...

We designed and built a new type of spatial mode multiplexer with no intrinsic loss and low crosstalk. In this first demonstration we show a multiplexer/demultiplexer with 3 modes: LP01, LP21a and LP21b with coupling loss below 9.9dB.

Information-Centric Networks for Distributed Computing

  • Pianese F.

Information-centric Networking (ICN), a paradigm that operates on self-contained named data, naturally extends the role and capabilities of in-network elements. The flexible naming of ICN can be used to convey instructions for content routers to perform a target computation. In this paper, we consider ICN's potential of integrating distributed computing ...
