Telecommunications Network Strategy and Planning Sym-posia. Since its first edition held in Paris thirty years ago, themeetings have been attracting world-class participants fromall over the world, ranging from telecom operators, regu-latory and standard bodies, through systems and softwarecompanies and research units from universities and indus-try, to systems integrators. The conference was organized byWarsaw University of Technology (Poland) in co-operationwith Polish Association of Telecommunication Engineers(Poland). The technical sponsors of the conference wereIEEE Poland Section, FP7 Network of Excellence Euro NF,and Polish Academy of Sciences.

Networks 2010 was a four-day professional and scientificevent focused on network design and planning methods in-cluding the issues of network planning and optimization thatare necessary to deliver the promise of the Network of theFuture. The motto of Networks 2010 was Networks for thee-Society.

The conference presentations addressed mainly the is-sues of optical networks design, management and optimiza-tion techniques, quality of service, economic aspects of net-work design, routing in future generation networks, eco-nomic evaluation of new solutions, routing methods andalgorithms (optimizing resource efficiency, robustness, andcosts), evolution and future generation of wireless systems,optimization in network planning including resilience, andnetwork security.

Around 100 technical papers submitted by researchersfrom America, Asia, Australia, and Europe were carefullyreviewed by the Members of the Technical Program Com-mittee and external reviewers. The accepted 51 high qualitypapers were finally organized into 16 technical sessions. Ontop of that, 6 keynote talks, 8 invited papers, and 4 tutori-als enriched the conference program. The conference wasattended by more than 130 participants. Conference papers

Authors of the top 17 regular papers have been invitedto publish extended versions of their papers in this specialissue of Telecommunication Systems Journal.

In “Volume-oriented routing and its modifications”, Ma-teusz Zotkiewicz and Walid Ben-Ameur present a newrouting paradigm where each traffic demand is routed in-dependently of the other demands: the volume-orientedrouting. The paper by David Hock, Matthias Hartmann,Michael Menth, Michał Pióro, Artur Tomaszewski andCezary Zukowski entitled “Comparison of IP-Based andExplicit Paths for One-to-One Fast Reroute in MPLS Net-works” propose a mixed-integer model for optimizing thepath layout for explicitly calculated paths, which can ei-ther produce single paths and route entire traffic alongthose paths, or generate multiple paths and spread the trafficamong those paths providing load balancing. In “Optimiz-ing Network Load Balancing: an Hybridization Approach ofMetaheuristics with Column Generation” Dorabella Santos,Amaro de Sousa, Filipe Alvelos and Michał Pióro show ahybridization approach using a metaheuristic with columngeneration not only at the beginning but also during thespace search.

Noriaki Kamiyama, Tatsuya Mori, Ryoichi Kawahara,Shigeaki Harada and Haruhisa Hasegawa in “Analyzing In-fluence of Network Topology on Designing ISP-operatedCDN” investigate the properties of the topological loca-tions of nodes at which cache placement is effective; theyclassify the evaluated networks into two types and deter-mine the optimum cache count in each network type. In“Least Cost Routing (LCR) solution for inter-domain traf-fic distribution”, Miroslaw Kantor, Piotr Chołda and An-drzej Jajszczyk consider the problem of route selection ina multi-homed stub network to optimize transit costs andpaths performance offered by an operator to its customers isaddressed.

Hiroshi Yamada, Takeshi Yada and Hiroto Nomura in“Developing network configuration management databasesystem and its application“ show the work in progress todevelop their database system and several data federationmethodologies for network management. “Proactive recov-ery from multiple failures utilizing overlay networking tech-nique” by Go Hasegawa, Takuro Horie and Masayuki Mu-rata proposes a proactive recovery method against multiplenetwork failures for large-scale packet switching networksthat exploits the overlay networking technique. TomaszMrugalski, Jozef Wozniak and Krzysztof Nowicki in “Dy-namic Host Configuration Protocol for IPv6 Improvementsfor Mobile Nodes” propose several new mechanisms thatenable faster IPv6 reconfiguration including a priori knowl-edge about configuration available at destination loca-tions.

“Lightpath Design & Management System for IP-over-CWDM Networks with ROADMs, Employing Parallel Pro-cessing” by Raja Zahilah, Yuta Ogino, Soichiro Nishi-uma, Md. Nooruzzaman, Nguyen Thi Thanh Thuy, OsanoriKoyama and Yutaka Katsuyama provides information on theauthors’ system that can process applications composed ofsome sub applications in parallel in multi machines for high-speed performance in IP-over-CWDM networks. KrzysztofWalkowiak and Jacek Rak in “Simultaneous Optimization ofUnicast and Anycast Flows and Replica Location in Surviv-able Optical Networks” formulate new mixed-integer pro-gramming models to find the optimal paths for anycast andunicast connections, as well as to find optimal locations forthe of replica servers.

Jean-Philippe Joseph in “PSTN Services Migration toIMS—Are Service Providers Finally Reaching the TippingPoint for Large Scale Migrations?” examines the SP’s needs,the services architectures and platforms, the access tech-nology alternatives, the inherent PSTN interworking re-quirements that need to be supported during the transi-tion, and pending implementation challenges. The paper“Integrated optimization of aggregation and core for vary-ing NGN architectures” by Ulrich Menne, Roland Wessäly,Maren Martens and Andreas Bley presents an optimizationframework to support network operators in assessing centralstrategic design and architecture questions regarding theirnext generation networks.

Kurt Majewski and Michael Koonert in “Analytic up-link cell load approximation for planning fractional powercontrol in LTE networks” establish a system of cell equa-tions for the uplink cell loads and blocking probabili-ties, taking Fractional Power Control parameters, irregu-lar cell areas, service specific user distributions, and mu-tual cell interference into account. In “Analytical model ofthe multi-service cellular network servicing multicast con-nections” by Damian Parniewicz, Maciej Stasiak and PiotrZwierzykowski, a new analytical method of blocking proba-bility calculation in multi-service cellular systems with mul-ticast connections is proposed.

Bartosz Jankowski, Wojciech Mazurczyk and KrzysztofSzczypiorski in “PadSteg: Introducing Inter-Protocol Stega-nography” introduce a new steganographic system calledPadSteg (Padding Steganography) that represents inter-protocol steganography, i.e., usage of relation between twoor more protocols from the TCP/IP stack to enable secretcommunication. Wojciech Mazurczyk, Miłosz Smolarczykand Krzysztof Szczypiorski in “On Information Hiding inRetransmissions” present an idea and experimental resultsfor RSTEG (Retransmission Steganography), which is anintra-protocol hybrid network steganography method thatenables hidden communication by not acknowledging a suc-

cessfully received packet in order to intentionally invoke re-transmission.

Finally, in the last paper in this issue entitled “Quantify-ing CAPEX Savings of Homing Architectures Enabled byFuture Optical Network Equipment” by Eleni Palkopoulou,Dominic Schupke and Thomas Bauschert focuses on sav-ings with respect to network equipment capital expenditures(CAPEX) achieved by transitioning to different homing ar-chitectures in an IP-over-optical data unit setting.

We believe that this Special Issue will contribute to en-hancing knowledge in many diverse areas of the moderntelecommunications. In addition, we also hope that the pre-sented results will stimulate further research in the importantareas of this scientific field.
