# A simpler proof for O(congestion + dilation) packet routing

@article{Rothvoss2012ASP, title={A simpler proof for O(congestion + dilation) packet routing}, author={Thomas Rothvoss}, journal={ArXiv}, year={2012}, volume={abs/1206.3718} }

In the store-and-forward routing problem, packets have to be routed along given paths such that the arrival time of the latest packet is minimized. A groundbreaking result of Leighton, Maggs and Rao says that this can always be done in time O(congestion + dilation), where the congestion is the maximum number of paths using an edge and the dilation is the maximum length of a path. However, the analysis is quite arcane and complicated and works by iteratively improving an infeasible schedule…

Near-Optimal Schedules for Simultaneous Multicasts

- MathematicsICALP
- 2021

A lower bound for multicasts is proved, which shows that there do not always exist schedules of non-trivial length, which means that this length cannot be improved to O(C+D) + o(\log n)$.

Near-Optimal Scheduling of Distributed Algorithms

- Computer SciencePODC
- 2015

This paper presents a distributed algorithm that produces a near-optimal O(congestion + dilation log n) round schedule, after O(dilation log2 n) rounds of pre-computation, and a key challenge in the latter result is to solve the problem with only private randomness, as globally-shared randomness simplifies it significantly.

A model of distributed computation that considers both computation and communication so as to give a theoretical treatment of data aggregation is introduced and a polynomial-time algorithm is given that computes the optimal schedule when the input network is a complete graph.

The Moser-Tardos Framework with Partial Resampling

A partial resampling approach that resample an appropriately-random subset of the set of variables that define this event, rather than the entire set as in Moser & Tardos, leads to several improved algorithmic applications in scheduling, graph transversals, packet routing etc.
