Virtual Network Embedding

Dear Colleagues,

With the rise of software-defined networking and network function virtualization, sophisticated optimization of complex communication networks is more important than ever. The field of virtual network embedding has emerged, discussing all aspects of the optimization of resource assignment in complex networks. Practical applications include federated cloud environments or mobile (5G) telecommunication networks.
The optimization itself often hits a performance bound, as the underlying resource assignment problem is found to be NP-complete. This requires elaborate heuristic algorithms. Solution approaches encompass all types of optimization algorithms, online and offline, with resource models ranging from simple numbers to elaborate node and link categories. Recently, advances in artificial intelligence and machine learning have also provided promising results this field. Further, the evaluation and in-depth comparison of related solution approaches has started to gain more attention.
In this Special Issue, we want to discuss recent research advances in this field. We invite novel contributions showing interesting and relevant results related to the keywords listed below.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Algorithms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
