An Adversarial Construction of Instability Bounds in LIS Networks

open access: yes, 2005
In this work, we study the impact of dynamically changing link slowdowns on the stability properties of packetswitched networks under the Adversarial Queueing Theory framework.

One-counter Markov decision processes [PDF]

open access: yes, 2010
We study the computational complexity of some central analysis problems for One-Counter Markov Decision Processes (OC-MDPs), a class of finitely-presented, countable-state MDPs.OC-MDPs extend finite-state MDPs with an unbounded counter.

The impact of network structure on the stability of greedy protocols

open access: yes, 2003
A packet-switching network is stable if the number of packets in the network remains bounded at all times. A very natural question that arises in the context of stability and instability properties of such networks is how network structure precisely ...

The robustness of stability under link and node failures

open access: yes, 2011
In the area of communication systems, stability refers to the property of keeping the amount of traffic in the system always bounded over time. Different communication system models have been proposed in order to capture the unpredictable behavior of ...

A Note on the use of topology extensions for provoking instability in communication networks

open access: yes, 2004
We study some aspects of the instability of the last-in-first-out (LIFO) scheduling protocol in under-loaded packet-switched networks under the Adversarial Queueing Theory model [Borodin et al., Journal of the ACM, 48(1):13--38,2001] which allows to ...

Adversarial Network Optimization under Bandit Feedback: Maximizing Utility in Non-Stationary Multi-Hop Networks

open access: yes
Stochastic Network Optimization (SNO) concerns scheduling in stochastic queueing systems and has been widely studied in network theory. Classical SNO algorithms require network conditions to be stationary w.r.t.

Adaptive Scheduling over a Wireless Channel under Constrained Jamming [PDF]

open access: yes, 2015
We consider a wireless channel between a single pair of stations (sender and receiver) that is being “watched” and disrupted by a malicious, adversarial jammer.

Deciding the FIFO Stability of Networks in Polynomial Time (full version

open access: yes, 2006
. FIFO is the most prominent queueing strategy due to its simplicity and the fact that it only works with local information. Its analysis within the adversarial queueing theory however has shown, that there are networks that are not stable under the FIFO

Systems Analysis and Management: Structure, Strategy, and Design

open access: yes, 1981
— Although instability in packet networks has been traditionally associated with overload conditions (because queueing network models show that, in simple configurations, only overload generates instability), some results showing instability in ...
