  • Hippelainen L.
  • Lal S.
  • Oliver I.
  • Ravidas S.

Network Functions Virtualization (NFV) helps in reducing the dependency on hardware equipments by virtualizing the telecommunication network functions. While the current works have considered different frameworks for NFV and various challenges associated with it, only a few have considered trust as an aspect of NFV. In this paper, we discuss ...

A scalable routing mechanism for stateful microservices

Scalability is an important requirement in the development and the operation of applications in a cloud environment. To handling heavy concurrency in the input load, many design-related and operational factors should be considered. The microservice architecture patterns provide better means to increase the scalability than traditional software architecture patterns. However, ...

Telecom strategies for service discovery in microservice environments

In order to communicate with another service, a service needs to know the address of other services. This knowledge can be acquired by a process called service discovery (SD). In a microservice architecture (MSA), unlike SOA, a service discovery framework has not been provided out of the box. In a ...

We demonstrate an intelligent symmetric-rate, 8 x 10- Gb/s, bi-directional time and wavelength-division multiplexed passive optical network (TWDM-PON) with 42-km reach, and 1:256 split. 1425-nm laser pump light provides distributed Raman amplification for the upstream channels (allowing lowcost low-power transmitters), serves as a low-rate telemetry channel, and powers an intelligent ...

From Scaling Disparities to Integrated Parallelism: A Decathlon for a Decade

  • Neilson D.
  • Winzer P.

Based on a variety of long-term network traffic data across different geographies and applications as well as long-term scaling trends of key information and communication technologies, we identify fundamental scaling disparities between technologies used to generate and process data and technologies used to transport data. These disparities could lead to ...

  • Lopez-Perez D.
  • Ming Ding
  • Tian Ding
  • Zihuai Lin

In this paper, we analyse the coverage probability and the area spectral efficiency (ASE) for the uplink (UL) of dense small cell networks (SCNs) considering a practical path loss model incorporating both line-of-sight (LoS) and non-line-of-sight (NLoS) transmissions. Compared with the existing work, we adopt the following novel approaches in ...

Multidimensional Mutual Information Characterization of Nonlinear Interactions over Time and Polarizations

  • Eriksson T.
  • Fehenberger T.
  • Idler W.

The achievable information rate is experimentally estimated in coherent fiber optical communication for different four dimensional descriptions of the channel to the demapper. Polarization-multiplexed 16-ary quadrature amplitude modulation with channel symbolrates of either 10 or 20 Gbaud are investigated in experiments over both erbium doped fiber amplifier based links and ...

Freedom of Speech: Thwarting Jammers via a Probabilistic Approach

  • Di Pietro R.
  • Oligeri G.

In this paper, we introduce a probabilistic protocol-Freedom of Speech (FoS)- that assures the delivery of the message to be broadcast (to n nodes) in the presence of a powerful jammer. FoS enjoys several features when compared to competing schemes: it requires each node to store just n symmetric pairwise ...

Risk Thinking for Cloud-Based Application Services

  • Bauer E.

Enterprises take risks, like developing new product/service offerings and expanding into new markets and sales channels, in pursuit of reward. Many enterprises are moving their applications and IT services to the cloud in pursuit of reduced operational expenses and an accelerated pace of service innovation without compromising user service quality. ...

Survey of cloud server geolocating techniques

  • Hippelainen L.
  • Lai S.
  • Oliver I.

Every cloud data center has a geographical location, which is known to, at least, its owner. Still, it is a challenge for a cloud customer to discover indisputably the location of the data center, which hosts an active cloud based service and its data. Knowing the location is necessary to ...

Coding for Distributed Fog Computing

  • Avestimehr S.
  • Li S.
  • Maddahali M.

Redundancy is abundant in Fog networks (i.e., many computing and storage points) and grows linearly with network size. We demonstrate the transformational role of coding in Fog computing for leveraging such redundancy to substantially reduce the bandwidth consumption and latency of computing. In particular, we discuss two recently proposed coding ...

  • Pang S.
  • Sun Y.
  • Yuan X.

We report a temporal compressive imaging system with side information. In addition to a coded measurement used to play the pivot role to reconstruct high speed video frames, we employ a second channel to capture the blurry image as side information to improve the reconstruction quality. These two channels are ...

Hashing Garbled Circuits for Free

  • Fan X.
  • Ganesh C.
  • Kolesnikov V.

We show how to generate Garbled Circuit (GC) hash at no extra overhead during GC generation. This is in contrast with state-of-the-art approaches, which hash GCs at computational cost of about $6times$ of GC generation. GC hashing is at the core of the cut-and-choose technique of GC-based secure function evaluation ...
