Learning Sub-Second Routing Optimization in Computer Networks requires Packet-Level Dynamics

no code implementations14 Oct 2024 Andreas Boltres, Niklas Freymuth, Patrick Jahnke, Holger Karl, Gerhard Neumann

To this end, we present $\textit{PackeRL}$, the first packet-level Reinforcement Learning environment for routing in generic network topologies.

Stability and Convergence of Distributed Stochastic Approximations with large Unbounded Stochastic Information Delays

no code implementations11 May 2023 Adrian Redder, Arunselvan Ramaswamy, Holger Karl

We generalize the Borkar-Meyn stability Theorem (BMT) to distributed stochastic approximations (SAs) with information delays that possess an arbitrary moment bound.

Multi-Agent Reinforcement Learning for Long-Term Network Resource Allocation through Auction: a V2X Application

no code implementations29 Jul 2022 Jing Tan, Ramin Khalili, Holger Karl, Artur Hecker

We formulate offloading of computational tasks from a dynamic group of mobile agents (e. g., cars) as decentralized decision making among autonomous agents.

Learning to Bid Long-Term: Multi-Agent Reinforcement Learning with Long-Term and Sparse Reward in Repeated Auction Games

1 code implementation5 Apr 2022 Jing Tan, Ramin Khalili, Holger Karl

We propose a multi-agent distributed reinforcement learning algorithm that balances between potentially conflicting short-term reward and sparse, delayed long-term reward, and learns with partial information in a dynamic environment.

Distributed gradient-based optimization in the presence of dependent aperiodic communication

no code implementations27 Jan 2022 Adrian Redder, Arunselvan Ramaswamy, Holger Karl

We show: If for any $p \ge0$ the processes that describe the success of communication between agents in a SSC network are $\alpha$-mixing with $n^{p-1}\alpha(n)$ summable, then the associated AoI processes are stochastically dominated by a random variable with finite $p$-th moment.

3DPG: Distributed Deep Deterministic Policy Gradient Algorithms for Networked Multi-Agent Systems

no code implementations3 Jan 2022 Adrian Redder, Arunselvan Ramaswamy, Holger Karl

We prove the asymptotic convergence of 3DPG even in the presence of potentially unbounded Age of Information (AoI).

Self-Driving Network and Service Coordination Using Deep Reinforcement Learning

1 code implementation2 Nov 2020 Stefan Schneider, Adnan Manzoor, Haydar Qarawlus, Rafael Schellenberg, Holger Karl, Ramin Khalili, Artur Hecker

While this typically works well for the considered scenario, the models often rely on unrealistic assumptions or on knowledge that is not available in practice (e. g., a priori knowledge).

The Softwarised Network Data Zoo

2 code implementations21 Oct 2019 Manuel Peuster, Stefan Schneider, Holger Karl

To this end, we introduce the "softwarised network data zoo" (SNDZoo), an open collection of software networking data sets aiming to streamline and ease machine learning research in the software networking domain.
