Each delay-sensitive real-time flow has a different end-to-end delay deadline, and has to be delivered by that deadline. In general, real-time flows are to be processed prior to delay-tolerant flows, and each real-time flow may have the relative priority depending on its relative importance of real-time flows. A software-defined networking (SDN) makes it possible to monitor and control flows dynamically in the centralized view of the overall network. In this paper, we propose a priority-adjustment algorithm to guarantee the different delay deadlines of real-time flows in SDN-based networks. Compared to other algorithms, simulation results indicate that the number of real-time flows that satisfy their deadlines is highest in the proposed algorithm.","PeriodicalId":239896,"journal":{"name":"2016 17th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130461796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the concept of Flow-Aware Networking with special focus on the limitation mechanism is outlined. The automatic limitation mechanism i.e., a mechanism which automatically selects the most suitable flow admission limit during a measurement cycle is proposed, presented and analyzed. This makes the router more robust and invulnerable to faulty set-ups. Simulations studies show that the average admission limit applied by the automatic mechanism is very close to the optimal static limit which proves great effectivity of the automatic mechanism.","PeriodicalId":239896,"journal":{"name":"2016 17th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114855993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, Vehicular Ad-hoc NETworks (VANETs) characterized by high mobility of vehicles and facing a number of other issues related with high frequency wireless communications and network disconnections, encounter major challenges related with reliability of message delivery. This issue, despite a number of relevant publications, has not been extensively researched so far. This paper is the first one to provide a definition of information resilience for VANETs and the respective taxonomy of challenges to resilient message delivery for all types of VANET applications (being adaptation of a general taxonomy of challenges for networked systems). Example challenges related to technical aspects of resilient message dissemination for PHY/MAC layer, broadcast transmission, and multi-hop routing are outlined in the final part of the paper.","PeriodicalId":239896,"journal":{"name":"2016 17th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121642175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose an integer linear programming based approach to optimally solve this problem in elastic optical networks, and show that the generalized problem of protecting against this failure is NP-hard. We find that protection against this type of failure can be provided with the trade-off of increased frequency slot consumption, compared to less-protected solutions.","PeriodicalId":239896,"journal":{"name":"2016 17th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130186776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To deliver IP Multimedia Subsystem (IMS) advanced services across multiple access networks, a cloud-based model likely improves not only flexibility in network management but also in service invocation. This model is particularly suitable for the inter-network between the IMS and Web Real-Time Communication (WebRTC) domain, which is a natural combination to significantly expand potential end-points of multimedia sessions. However, optimally allocating resource for each component in the system to provide QoS is challenging, and has not been fully considered in prior work. In this paper, we investigate an NFV architecture to enable effective communication between IMS and WebRTC users supporting smart community services, and propose an optimization model to design and allocate resources for such system while ensuring desired QoS level. Experimental results show our algorithms effectively allocate required amounts of resources for virtual components according to real-time increase or decrease in user demand.","PeriodicalId":239896,"journal":{"name":"2016 17th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126416184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The packets from each packet stream are generated at the stream's source node and traverse a number of wireless nodes in order to reach their multiple destination nodes. Packet periodicity means that a common repeatable frame of time slots is defined and that the packets to be transmitted arrive at the source of each packet stream at the beginning of each consecutive frame. The novel element is that the packet transmitted by the node is simultaneously received by multiple listening nodes. The particular problem dealt with in the paper consists in minimization of the frame length (which is equivalent to packet throughput maximization) together with optimization of the multicast trees to be used by the packet streams. For that, we develop an integer-programming optimization model and the related near-optimal algorithm whose (very good) effectiveness is illustrated with numerical results.","PeriodicalId":239896,"journal":{"name":"2016 17th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125129403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current radio-frequency (RF) management technologies using ray-tracing or radio propagation modeling can estimate the radio signal strength in an entire cell area, but these accuracies are insufficient and ray-tracing takes a very long time to calculate. While measurement data at user equipment collected via the cell-trace function at base stations or crowdsourcing schemes are comparatively accurate, they are not included in the entire cell area. Our management framework selects the best of both technologies.

The key performance indicator is the average consumption of energy for one hour of Video. The energy savings that could be achieved implementing the results of the project in head-end, networks and terminals parts are evaluated economically for the European market. We obtain an order of magnitude of some hundred millions Euros savings per year. It remains small at the European level.
