abstract = {The industry is striving to deploy private cellular networks in their 

factories. 

The envisioned use cases, such as industrial automation, require 

Ultra-Reliable and Low-Latency Communications (URLLC). 

In 5G, the User Plane Function (UPF) handles user traffic and hence 

significantly influences the performance in terms of latency and 

throughput. 

However, present UPFs are often user-space applications running on 

commercial off-the-shelf (COTS) servers introducing computational delays 

that follow long-tailed distributions. 

In this work, we compare modern packet processing acceleration technologies 

such as XDP, DPDK, and P4 and their respective tail-latency performance. 

Our results demonstrate the clear advantage of hardware-based P4 

implementations in terms of reduced tail-latency of about 6 μs at a 

percentile of 99.999% for small packets. 

Furthermore, we also demonstrate that software-based frameworks can compete 

with hardware-based approaches. 

For example, DPDK achieves tail-latencies of approximately 23 μs at a 

percentile of 99.999%. 

Based on our findings, we illustrate the trade-offs between low-cost 

software- and high-performant hardware-based packet processing systems.},

The focus is on whether 5G connections can meet the requirements specified by 3GPP in terms of delay and reliability. The results indicate that without cross-traffic, the requirement of a delay of less than 10 ms for 99.9 % of the packets can be met for the remote control and fleet management of mobile robots. However, as soon as cross-traffic is injected, especially in the uplink, the upper percentiles of the delay increase significantly, thus failing to hold the reliability requirements.},

abstract = {Delivering content from a network via a client-server architecture is 

expensive not only for content owners but also for network operators. 

Moving content closer to the end user is already used in Content Delivery 

Networks (CDN). Mobile Edge Cloud (MEC) enables us to shift the content 

even closer by using the storage of end users. But, due to the large media 

files, storage and transport costs for peers increase significantly. 

Network Coding can reduce these costs. However, peers in CDNs tend to be 

highly fluctuating and often need to be restored, making continuous 

availability of data at the network edge a problem. While for uncoded data, 

individual packets lost due to peer failures can be tracked to determine 

availability, the availability of coded data is currently distinguished 

only in two cases: either there are still enough linearly independent 

packets to decode the file, or there are not. However, we have found that 

the network's combined coded cache loses quality over time due to recovery. 

This quality loss, which we refer to as grade, can be measured by very 

cost-effective monitoring. If the grade falls below a certain limit, we can 

intervene in the network by performing a cache refresh to prevent data 

becoming unavailable preemptively. In this paper, we present the cases in 

which such monitoring is useful, how the grade is calculated, and when a 

cache refresh is necessary. The results show that we can reduce network 

traffic by up to 34 % with minimal storage costs through efficient 

monitoring.},

abstract = {Photonic Integrated Circuit (PIC) have outperformed its electrical counterpart in terms of on-chip processing 

and power consumption by transmitting and computing optical signals at ultra-high speed, using less energy. However, fully 

functional optical transceivers are still rare. This work introduces the design and implementation of a tunable transceiver and an 

optical communication network on top of an external laser source, functioning in the near-Infrared (IR) range. The transceiver 

is composed of the integrated circuit of an optical chip, a hardware acceleration interface, and a customized Digital-toAnalog Converter (DAC) at the transmitter and receiver side. The 

photonic chip was designed and fabricated on CMOS compatible and represents an integrated Optical Phased Array (OPA), 

which modulates light for multi-channel beam control. The twodimensional beam steering relies on an array of waveguide 

grating couplers, which ensures high accuracy and directionality during the narrow beam radiation. In the longitudinal direction, 

the beam is steered by a wavelength tuning mechanism, while for the lateral direction, the lobe is controlled by a network of 

thermo-optical phase shifters. The hardware accelerator, a Multiprocessor System-on-Chip (MPSoC), computes the source data 

with random coefficient in Galois Fields (GF) to generate coded packets, which flow throughout the optical beams. Additionally, 

the accelerator is also responsible for the selection of the input voltage within the DACs to control the optical chip. To ensure 

successful packet transmission when the transmitter and receiver are in motion, a dynamic sliding window protocol based on 

Random Linear Network Coding (RLNC) was designed and implemented at the MAC layer. Extensive simulation demonstrates 

that our implementation results in an average packet success rate of 93.58 % with reduction in average delay.},

Software-Defined Networking (SDN) enables dynamic adaptation to changing network environments through the ability to program network behavior. However, to react properly to changing environments, precise and credible information about performance metrics such as latency is necessary. Recent research activities exploited OpenFlow, an SDN protocol, to measure delays inside the network, without the need for additional hard- or software. In this paper, we propose an improved method to measure one-way delays, which can handle asymmetrical delays between the SDN controller and the switches. We implemented our approach in a hardware testbed to evaluate it in a setup with asymmetrical delays and traffic loads. The results show that we are able to measure asymmetrical delays in the network. Additionally, the proposed solution is capable of discovering the network topology and therefore gives together with the performance metrics the information for efficient routing decisions. In addition, we make the source code of our implementation publicly available.},

However, more complex tasks still require to be done by a human in remote control. One example would be robot remote surgery. Remote controlling a robot requires ultra-low latency on the communication, to allow fast and precise movements. To make this possible with today's systems, the human operator must be in the same room. Enabling the operator to operate from anywhere around the world, would bring a huge benefit as travels for highly trained experts can be minimized. In order to allow wider distances between the operator and robot, we propose an AI-based prediction. Predicting the robots behavior can generate negative latency, which improves the precision of control. In large-scale communication networks, the main part of experienced latency comes from the propagation delay and is therefore not avoidable. Predicting upcoming data before it actually arrives, can create a zero-latency experience for the human operator. To prove this idea in the context of remote robot control, we propose JAVRIS. Using the CMIYC demonstrator as example, JAVRIS improved the score of an inexperienced user by over 1000%.},

Their integration, even though critical, lacks a detailed discussion in the literature. This paper highlights the critical roles of integrating tactile electronics and softwarised networks aiming at increasing adaption. We systematically address three components of such integration, namely the wireless frontend and medium access, data compression, and adaptation. Finally, we present eGlove, a prototypical wireless sensor testbed to capture the position of the hand and the motion of each finger, a significant step to future evaluation.},

Although the collection of large data sets can be used for many solutions, its utilization is made difficult by the increased overhead on the transmission and limited processing capabilities of the underlying physical system. For such highly correlated and extensive data, this situation is usually described as data-rich, information-poor. We propose for the first time a novel one-stage method, called Information-Abstraction-Net (IA-Net), for the detection of abnormal events in multi-object anomaly detection scenarios by 

utilizing highly abstracted sensory information instead of the entire sampled data set to elevate the transmission and analysis needs of the system. We find that the computation complexity of IA-Net is reduced by half compared to competing solutions and the detection accuracy is increased by about 5-47%, as well.},

abstract = {Live migration is a technology that seamlessly relocates a virtualized service between physical hosts, which allows services to rapidly adapt to environmental changes. Despite the large amount of research, mainly aiming at minimizing the downtime, there is still a lack of understanding of its performance using the most common off-the-shelf virtualization technologies, namely docker containers and KVM. Understanding the barriers of live migration will give companies the knowledge on whether the migration is possible or not, when the migration needs to be triggered, how many resources the migration will use, and under which conditions the migration will be successful. Moreover, it helps to detect bottlenecks, and also to identify which parts of the migration need to be improved. Towards a better understanding of live migration, we build a testbed and use it to migrate a computation-intensive application with docker and KVM. We evaluate the service downtime, migration time, and network usage under different conditions. The results show that KVM outperforms docker in most of the scenarios, with some critical exceptions where only docker manages to perform migration.},

abstract = {Currently, most IoT services are hosted centralized 

in a cloud. However, they rely on data gathered by numerous 

distributed sensors, which require to be connected to these clouds. 

At the moment this is realized with non-IP based proprietary 

wireless sensor networks that use inflexible networking concepts 

and require to be carefully configured. 

The Thread protocol, with its implementation OpenThread, is 

a new wireless mesh approach to solve this problem. OpenThread 

is maintained by the Thread group, which is an organization 

supported by almost 300 companies, including Google, Amazon, 

and Apple. Its design is based on an IPv6, for seamless integration 

in existing IP networks. 

This work, after a short a practical overview of the Thread 

protocol in general, investigates the network performance in 

different interference scenarios based on results from a hardware 

testbed, set up in an office building. This testbed is based on 

the Nordic Semiconductor nRF52840 System on a Chip (SoC), 

running OpenThread from the official github repository. Besides 

a thorough examination for round-trip-time (RTT) and losses, a 

stability test was performed over five weeks, to see the impact 

of interference during business hours. We measured RTTs in 

the range of 10 to 100 ms and losses up to 40% depending 

on interfering wireless services. Despite its obvious advantages, 

from our experimental results, it is evident how some practical 

limitations make OpenThread not always a good choice.},

abstract = {The advent of Microservice (MS) architectures has led to increasingly complex communication patterns between distributed web applications in the cloud. In order to process an incoming request, each MS must invoke multiple remote API calls to the MSes that it is connected to along a service dependency graph. This allows attackers to exploit long-running remote API calls along the performance-critical path to cause application DoS, and potentially amplify subsequent inter-MS communication. This paper focuses on mitigating a class of stealthy, low-volume DDoS attacks that are launched internally from within and exploit this. The attacker uses the MSes under its control to disguise then send and resource-heavy requests to target MSes in a way that is indistinguishable from benign requests. We propose a probabilistic algorithm to proactively identify MSes involved in DDoS, and mitigate the attack in real-time.},
