Scope

QoS routing represents a radical shift from the traditional connectivity-based approach  of currently deployed intra-domain (e.g., OSPF) and inter-domain (e.g., BGP) routing protocols. It calls for QoS-sensitive scalable solutions for path selection, state dissemination, multicasting, and topology aggregation. Emerging Internet services such as Differentiated Services (Diffserv) and Multi-Protocol Label Switching (MPLS) are likely to both require and justify the need for QoS-based routing solutions. This is reflected in a number of recent standardization activities that acknowledge the importance of QoS routing and that call for efficient, scalable solutions to it. Nonetheless, it has been recently recognized that existing QoS routing solutions have been developed at some distance from the task of development of QoS architectures. In particular, current QoS architectural models, including Diffserv, seem to implicitly assume that various classes of traffic are forwarded along the same (best-effort) path, with service differentiation being achieved locally through appropriate packet scheduling at each router. Decoupling routing and QoS provisioning can lead to inefficient selection of routes, reducing the likelihood of  meeting the applications' end-to-end QoS requirements.

In recent years, extensive research has been published on QoS routing mechanisms, often in the context of traffic engineering. Several issues have been adequately addressed, while others remain to be tackled. The purpose of this Feature Topic is to summarize the state-of-the-art in QoS routing research. We solicit tutorial research articles and surveys that report on experimental and theoretical studies related to QoS routing. Topics of interest include, but are not limited to, the following:

Constraint-based path selection algorithms
Scalable state dissemination
Stateless QoS routing frameworks
Topology aggregation for hierarchical, QoS-based routing
QoS routing for traffic engineering
Fault-tolerant routing
Tradeoff between scalability and performance in QoS routing
QoS routing in optical networks
Multicast routing
Impact of Internet topologies on QoS routing
Localized QoS routing solutions
QoS routing in mobile and ad-hoc networks
Tools for evaluating QoS routing mechanisms

Submission Instructions

Authors are encouraged to submit their manuscripts by email as an attachment to one of the guest editors. Acceptable formats are limited to Postscript and PDF. Paper submission should adhere to the submission guidelines of the IEEE Communications Magazine. In particular, submitted articles should be tutorial in nature and should be written in a style comprehensible to readers outside the specialty of the article. Articles may be edited for content, and will be copy edited for compliance with the magazine's style guidelines. Page proofs will be sent to the contact author for final review prior to publication. Details of the submission guidelines can be found at http://www.comsoc.org/~ci (under Submissions).

Submissions should indicate the name and contact information (address, phone, fax, email) of the corresponding author.
