LEDBAT-MP - on the Application of Lower-Than-Best-Effort for Concurrent Multipath Transfer

LEDBAT-MP - on the Application of Lower-Than-Best-Effort for Concurrent Multipath Transfer
The Internet is based on best effort communication, i.e. it tries to deliver packets but does not provide any guarantees. A transport protocol can make use of this best effort service to provide a suitable service to its applications. Also, its congestion control is responsible for a fair distribution of the resources within the Internet. However, background data transfer applications (like file sharing or update fetching) do not require "best effort"; they in fact could use a "lower-than-best-effort" service to leave resources to more important applications if needed. For this purpose, the Low Extra Delay Background Transport (LEDBAT) algorithm has been standardized by the IETF. Nowadays, multi-homing is becoming increasingly common in modern networks and several approaches to exploit this feature (e.g. CMT-SCTP, MPTCP) have evolved that are able to combine resources of multiple paths. For background traffic oriented algorithms like LEDBAT, this feature could be of great use, too, i.e. by increasing the overall bandwidth while shifting the transmission away from paths which are used by other flows. This could be particularly useful for non-critical bulk transfers in data centers. In this paper, we introduce our approach LEDBAT for Multi-Path - denoted as LEDBAT-MP - and analyse its performance by simulations. With this paper, we want to highlight some generic design questions and start a discussion on how a solid universal background multi-path congestion control strategy should behave.

Eclipse: A New Dynamic Delay-based Congestion Control Algorithm for Background Traffic

Eclipse: A New Dynamic Delay-based Congestion Control Algorithm for Background Traffic
Initially, the Internet transport protocol TCP has been designed to provide a "best effort" service: it is meant to share the network resources with other users and applications. However, there is nowadays also a growing demand for transmitting big amounts of data in the background, namely background transport that uses spare capacity, but with minimal effect on other traffic. For instance, systems can proactively download content that the user/system would need in the future (e.g. update packages, video files, etc.). Efforts have therefore been made in the IETF for the sake of such a service with Low Extra Delay Background Traffic (LEDBAT) congestion control. While LEDBAT works in some cases, there are however known situations where it causes serious performance problems, particularly in combination with the ubiquitous bufferbloat for example in current broadband networks.
In this paper, we analyse the issues of LEDBAT and propose a new approach for background traffic. Inspired by an astronomical event, we have named this approach Eclipse. Unlike LEDBAT, Eclipse can dynamically adapt to the network characteristics not only to minimise the additional network delay but also to maximise the utilisation of spare network capacity. We will show the usefulness of Eclipse by simulations.

Social Media and Satellites. Disaster event detection, linking and summarization

Social Media and Satellites. Disaster event detection, linking and summarization
Being able to automatically link social media and satellite imagery holds large opportunities for research, with a potentially considerable impact on society. The possibility of integrating different information sources opens in fact to new scenarios where the wide coverage of satellite imaging can be used as a collector of the fine-grained details provided by the social media. Remote-sensed data and social media data can well complement each other, integrating the wide perspective provided by the satellite view with the information collected locally, being it textual, audio, or visual. Among the possible applications, natural disasters are certainly one of the most interesting scenarios, where global and local perspectives are needed at the same time.
In this paper, we present a system called JORD that is able to autonomously collect social media data (including the text analysis in local languages) about technological and environmental disasters, and link it automatically to remote-sensed data. Moreover, in order to ensure the quality of retrieved information, JORD is equipped with a hierarchical filtering mechanism relying on the temporal information and the content analysis of retrieved multimedia data.
To show the capabilities of the system, we present a large number of disaster events detected by the system, and we evaluate both the quality of the provided information about the events and the usefulness of JORD from potential users viewpoint, using crowdsourcing.

Automatic detection of passable roads after floods in remote sensed and social media data
Signal Processing: Image Communication 74 (2019): 110-118.Status: Published
Automatic detection of passable roads after floods in remote sensed and social media data
This paper addresses the problem of floods classification and floods aftermath detection based onboth social media and satellite imagery. Automatic detection of disasters such as floods is still a very challenging task. The focus lies on identifying passable routes or roads during floods. Two novel solutions are presented, which were developed for two corresponding tasks at the MediaEval 2018 benchmarking challenge. The tasks are (i) identification of images providing evidence for road passability and (ii) differentiation and detection of passable and non-passable roads in images from two complementary sources of information. For the first challenge, we mainly rely on object and scene-level features extracted through multiple deep models pre-trained on the ImageNet and Places datasets. The object and scene-level features are then combined using early, late and double fusion techniques. To identify whether or not it is possible for a vehicle to pass a road in satellite images, we rely on Convolutional Neural Networks and a transfer learning-based classification approach. The evaluation of the proposed methods is carried out on the large-scale datasets provided for the benchmark competition. The results demonstrate significant improvement in the performance over the recent state-of-art approaches.

Control Principles for Autonomous Communication Networks
In Oslomet, 2023.Status: Published
Control Principles for Autonomous Communication Networks
The growing complexity of communication networks and the explosion of network traffic have made the task of managing these networks exceedingly hard. A potential approach for striking this increasing complexity is to build an autonomous self-driving network that can measure, analyze and control itself in real time and in an automated fashion with- out direct human intervention. In this thesis, we focus on realizing such an autonomous network leveraging state-of-the-art networking technologies along with artificial intelli- gence and machine learning techniques. Toward this goal, we exploit different learning paradigms to automate network management. First, we propose supervised machine learning methods to detect increases in delays in mobile broadband networks. Further, considering the challenges of supervised learning in networking applications, we present a novel real-time distributed architecture for detecting anomalies in mobile network data in an unsupervised fashion. It also involves a collaborative framework for knowledge sharing between the distributed probes in the network to improve the overall system accuracy. Second, we propose a novel deep reinforcement learning based control framework for op- timizing resources utilization while minimizing performance degradation in multi-slice Radio Access Network (RAN) through a set of diverse control actions. We explore both centralized and distributed control architectures. Last, we design a framework for timely collecting telemetry, detecting and attributing outages in mobile networks. We evaluate our framework on a software defined virtualised testbed that resembles a cloudified mobile network.
