Towards Optimal Path Allocation for Unreliable Reconfigurable Intelligent Surfaces
Mounir Bensalem, Anna Engelmann, Admela Jukan
Terahertz (THz) communications and reconfigurable intelligent surfaces (RISs) have been recently proposed to enable various powerful indoor applications, such as wireless virtual r…
Engineering Edge-Cloud Offloading of Big Data for Channel Modelling in THz-range Communications
Zied Ennaceur, Anna Engelmann, Admela Jukan
Channel estimation in mmWave and THz-range wireless communications (producing Gb/Tb-range of data) is critical to configuring system parameters related to transmission signal quali…
A Simple Reliability Analysis of Complex Service Function Chains (SFCs)
Anna Engelmann, Admela Jukan
In the framework of Network Function Virtualization (NFV), the reliability of Service Function Chain (SFC), -- an end-to-end service is presented by a chain of virtual network func…
Error Correction with Systematic RLNC in Multi-Channel THz Communication Systems
Cao Vien Phung, Anna Engelmann, Admela Jukan
The terahertz (THz) frequency band (0.3-10THz) has the advantage of large available bandwidth and is a candidate to satisfy the ever increasing mobile traffic in wireless communica…
Improving THz Quality-of-Transmission with Systematic RLNC and Auxiliary Channels
Cao Vien Phung, Anna Engelmann, Thomas Kuerner +1
In this paper, we propose a novel solution that can improve the quality of THz transmission with systematic random linear network coding (sRLNC) and a low-bitrate auxiliary channel…
Mitigating Censorship with Multi-Circuit Tor and Linear Network Coding
Anna Engelmann, Admela Jukan
Anonymity networks are providing practical mechanisms to protect its users against censorship by hiding their identity and information content. The best-known anonymity network, Th…
On Coding for Reliable VNF Chaining in DCNs
Anna Engelmann, Admela Jukan, Rastin Pries
We study how erasure coding can improve service reliability in Data Center Networks (DCN). To this end, we find that coding can be best deployed in systems, where i) traffic is spl…
A Reliability Study of Parallelized VNF Chaining
Anna Engelmann, Admela Jukan
In this paper, we study end-to-end service reliability in Data Center Networks (DCN) with flow and Service Function Chains (SFCs) parallelism. In our approach, we consider large fl…
Exploiting Parallelism in Optical Network Systems: A Case Study of Random Linear Network Coding (RLNC) in Ethernet-over-Optical Networks
Anna Engelmann, Wolfgang Bziuk, Admela Jukan +1
As parallelism becomes critically important in the semiconductor technology, high-performance computing, and cloud applications, parallel network systems will increasingly follow s…
Practical Privacy in WDM Networks with All-Optical Layered Encryption
Anna Engelmann, Admela Jukan
Privacy in form of anonymous communication could be comparably both faster and harder to break in optical routers than in today's anonymous IP networks based on The Onion Routing (…
Computationally Secure Optical Transmission Systems with Optical Encryption at Line Rate
Anna Engelmann, Admela Jukan
We propose a novel system for optical encryption based on an optical XOR and optical Linear Feedback Shift Register (oLFSRs). Though we choose LFSR for its ability to process optic…
DiffFlow: Differentiating Short and Long Flows for Load Balancing in Data Center Networks
Francisco Carpio, Anna Engelmann, Admela Jukan
In current Data Center Networks (DCNs), Equal- Cost MultiPath (ECMP) is used as the de-facto routing protocol. However, ECMP does not differentiate between short and long flows, th…
Optical Onion Routing
Anna Engelmann, Admela Jukan
As more and more data is transmitted in the configurable optical layer, whereby all optical switches forward packets without electronic layers involved, we envision privacy as the…
Balancing the Demands of Reliability and Security with Linear Network Coding in Optical Networks
Anna Engelmann, Admela Jukan
Recently, physical layer security in the optical layer has gained significant traction. Security treats in optical networks generally impact the reliability of optical transmission…
