Special Issue Information

Dear Colleagues,

QoS is still a key element in any packet network technology. Despite important QoS advances in data communication networks, QoS is still an issue that challenges the scientific community. Current data services are provided by deeply heterogeneous networks (usually, in the area of mobility). QoS requires an end to end study of access networks and their interconnections; this is increasingly critical as bandwidth access grows. Service convergence and integration necessitate high speed networks that are able to match user contracts with traffic control and traffic management in a seamless mode. From the user’s perspective, the QoS required by different applications can be quite variable. Similarly, for a given application type, different users may require, or be satisfied with, differing levels of QoS and QoE. This Special Issue invites papers addressing and advancing QoS and QoE themes in the Internet context, including papers discussing issues that increasingly arise as a result of mobile and wireless access. Topics of interest include (but are not limited to) the core technologies, protocols, services, and applications that can provide better levels of QoS and QoE in wired and wireless data networks.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Future Internet 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 1600 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.

Packet scheduling is key to quality of service (QoS) capabilities of broadband wired and wireless networks. In a heterogeneous traffic environment, a comprehensive QoS packet scheduler must strike a balance between flow fairness and access delay. Many advanced packet scheduling solutions have targeted fair bandwidth allocation while protecting delay-constrained traffic by adding priority queue(s) on top of a fair bandwidth scheduler. Priority queues are known to cause performance uncertainties and, thus, various modifications have been proposed. In this paper, we present a packet queueing engine dubbed Fractional Service Buffer (FSB), which, when coupled with a configurable flow scheduler, can achieve desired QoS objectives, such as fair throughputs and differentiated delay guarantees. Key performance metrics, such as delay limit and probability of delay limit violation, are derived as a function of key FSB parameters for each delay class in the packet queueing engine using diffusion approximations. OPNET simulations verify these analytical results. Full article
