Faster Heavy Hitters on Sliding Windows

  • Ben Bassat Ran
  • Einziger G.
  • Waisbard E.

Sliding window measurement is required by network functionalities such as load balancing, traffic engineering and intrusion detection. This work focuses on two fundamental problems -- identifying Heavy Hitters (HH) and Hierarchical Heavy Hitters (HHH) over sliding windows. We introduce two rigorously analyzed algorithms for the HH and HHH problems and ...

  • Qi L.
  • Sun G.
  • Yu H.

Texture synthesis methods based on patch sampling and pasting that can generate realistic textures with a similar appearance to a small sample. However, the sample usually has to be used throughout the synthesis stage. In contrast, the learnt representation of the textures is more compact and discriminative, and can also ...

Disaggregated optical technologies have the potential to provide cost-effective and vendor-neutral optical node solutions especially suitable for metro networks. Differently from the conventional proprietary networks, specific design, modelling, control and management operations have to be carefully defined and standardized. This paper first presents the most relevant disaggregated optical devices such ...

Providing ultra-reliable low latency services for 5G with unattended datacenters

  • Hilt A.
  • Jaro G.
  • Rotter C.
  • Varga J.

The strict requirements imposed by ultra-reliable low latency (uRLL) services in 5G can be costly for 5G network operators: low latency requires the deployment of distributed datacenters, while ultra-reliability usually means attended datacenters. This paper checks whether it is possible to operate the datacenters hosting uRLL services without on-site support ...

A chair based ballistocardiogram time interval measurement with cardiovascular provocations

  • Ahmaniemi T.
  • Lindholm H.
  • Muller K.
  • Rajala S.
  • Taipalus T.

The objective of this study was to measure ballistocardiogram (BCG) based time intervals and compare them with systolic blood pressure values. Electrocardiogram (ECG) and BCG signals of six subjects sitting in a chair were measured with a ferroelectric film sensor. Time intervals between ECG R peak and BCG I and ...

140/180/204-Gbaud OOK Transceiver for Inter- and Intra-Data Center Connectivity

We report on an on-off keying intensity-modulation and direct-detection C-band optical transceiver capable of addressing all datacenter interconnect environments at well-beyond 100Gbaud. For this, the transmitter makes use of two key InP technologies: a 2:1 double heterojunction bipolar transistor selector multiplexer and a monolithically integrated distributed-feedback laser traveling-wave electro-absorption modulator, ...

In this paper, we address and analyze the receiver reference sensitivity requirements for the 5G New Radio (NR) wireless communications systems, which relate to the SNR requirements at the base station to reach 95 % of the maximum throughput defined for fixed reference channels. Based on the latest 3GPP specifications ...

Would Scaling to Extreme Ultra-Violet or Soft X-Ray Communications Resolve the Capacity Crunch?

  • Winzer P.

Optical networks are facing fundamental capacity scalability problems owing to Shannon limits in silica fiber, frequently summarized as the "optical networks capacity crunch". We explore the possibility of scaling communication capacities through the use of significantly higher carrier frequencies, such as the extreme ultra-violet or the soft x-ray spectral region, ...

Online Label Recovery for Deep Learning-based Communication through Error Correcting Codes

We demonstrate that error correcting codes (ECCs) can be used to construct a labeled data set for finetuning of "trainable" communication systems without sacrificing resources for the transmission of known symbols. This enables adaptive systems, which can be trained on-the-fly to compensate for slow fluctuations in channel conditions or varying ...

EIRP, TRP, Partial TRP and Radiated Immunity For 5G millimeter Wave Device Compliance

  • Moongilan D.

5G millimeter wave devices and low frequency devices have different FCC compliance requirements. The 5G millimeter wave devices must meet new parameters such as sum of equivalent isotropic power (EIRP) and total radiated power (TRP). Massive MIMO devices must be evaluated differently as compared to conventional MIMO devices. The network ...
