[WoNeCa-6] Hybrid Event on 8th-9th September 2022

Congratulations to both !

The Workshop

Network calculus is a versatile methodology for the queueing analysis of resource-sharing systems. It can deal with problems that are fundamentally hard for alternative methodologies, using bounds rather than striving for exact solutions. The high modeling power of network calculus has been used in several important network engineering applications such as time sensitive networks, wireless sensor networks and Systems-on-Chip.

The goal of this workshop is to bring together researchers with an interest in the theory of network calculus as well as those who want to apply existing results in new applications. The workshop will serve to promote the network calculus theory to researchers with an interest in applied queueing models for data communication.

Call for Presentations

The idea is to have an informal meeting with presentations of recent work in the context of network calculus (theory, applications, tool support) and gather as many network calculus experts as possible to discuss about the future development of the theory and its application opportunities. Hence, there are no written papers and everyone can present his/her "hottest" recent research on network calculus.

The workshop is open to everyone who is interested in network calculus. If you would like to present you will need to submit:

  1. The title of your presentation.
  2. The abstract of your presentation.
  3. The name of the presenter.
Click HERE to submit the title, the abstract and the name. The submission period is over.

In case of contention, presentations will be selected based on topical coherence.
