While some of these middleboxes are transparent and passively monitor the network, others can directly affect the data traffic (e.g., content accelerators). Forecasting user and middlebox traffic patterns are usually done through oversimplified models and sometimes unrealistic assumptions. In this context, network planning and dimensioning has become a complicated and sophisticated task. Even though virtualization technology today allows one to build experimental networks that can aid the task of network planning, this is hindered by lack of adequate functions in existing virtualization platforms. Amongst those functions are the support for refined network configurations and modification of software and operating system configurations running inside a virtual machine. In this paper we present VIBox, a tool for network planning experimentation that aims at creating virtual networks in a simple and user-friendly way.","PeriodicalId":202408,"journal":{"name":"2010 14th International Telecommunications Network Strategy and Planning Symposium (NETWORKS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115946181","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 attempt to answer these critical questions by means of a practical methodology. We demonstrate that a converged transport network architecture with Next-Generation Optical Transport Network (NG-OTN) technologies meets the carrier's requirements at minimum capital investment. We support this network transformation solution with a comprehensive case study of the evolution of an actual service provider's optical backbone network with a realistic service mix, traffic growth and cost models. The network transformation introduces the convergence of multiple services and transport layers using NG-OTN technologies, and performs a network design optimization to meet the scalability, flexibility and resiliency requirements while minimizing the investment in infrastructure and network operations.","PeriodicalId":202408,"journal":{"name":"2010 14th International Telecommunications Network Strategy and Planning Symposium (NETWORKS)","volume":"23 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120930533","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 use of virtual topologies is a good alternative to build wireless multi-hop networks. It aims to maintain a topology that optimizes broadcasting or network performances. The problem is to determine an appropriate topology for ad hoc networks. This paper proposes a methodology for building distributed and dynamic virtual topology in ad hoc networks based on the concept of dominating sets. Dominating nodes are used to form a tree structure inside the clusters where the root of the tree is the cluster-head. The idea is to form a clustered network over which communication protocol can be efficiently designed.","PeriodicalId":202408,"journal":{"name":"2010 14th International Telecommunications Network Strategy and Planning Symposium (NETWORKS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134303790","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 concept of network efficiency optimization by building the routing tree characterized by selected topological properties that are independent on network load is presented. As an important partial result, correlations between topological parameters of the tree and network efficiency have been estimated. The parameters exhibiting the strongest correlations allow creation of well performing routing trees by optimizing the tree topology only. In order to estimate the network performance under load a fast, modular WiMAX network simulator has been created.","PeriodicalId":202408,"journal":{"name":"2010 14th International Telecommunications Network Strategy and Planning Symposium (NETWORKS)","volume":"173 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131752513","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 first propose a model that deals with selecting the number of routers and their types to install in each point of presence, selecting the interface card types to install in each router, finding the access and the backbone networks, interconnecting the routers in each point of presence, selecting the link types and finally, routing the traffic. The objective is to find the minimum cost network. Moreover, we consider that a minimum information rate (in bps) is guaranteed between each pair of clients for the normal state of the network and for the failure scenarios of interest to the network planner. A tabu search metaheuristic algorithm is proposed to find near-optimal approximate solutions of the model. Finally, we present numerical results to assess the performance of the proposed algorithm.","PeriodicalId":202408,"journal":{"name":"2010 14th International Telecommunications Network Strategy and Planning Symposium (NETWORKS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125351478","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 proposed approach is to build multicast trees, over which the content files are sent to user disks, followed by delayed local playback of the content. The work concentrates on exact and heuristic methods for an efficient tree packing in several download periods. In order to satisfy all the requests accumulated in a certain time period, we choose to minimize the number of times a multicast tree is split because of capacity constrains. We show that this objective provides lowest link utilization and good convergence both in the integer formulation and in the developed heuristics (of type tabu search, iterated local search, and variable neighborhood search). The model can be also used in a planning setting to answer the question on the maximum user request rate that can be supported by a certain network topology.","PeriodicalId":202408,"journal":{"name":"2010 14th International Telecommunications Network Strategy and Planning Symposium (NETWORKS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125420420","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}

In this paper we propose a new approach to network survivability of anycast communications. To the best of our knowledge, anycast defined as one-to-one-of-many technique has not received much attention recently. To provide network survivability, we use the single backup path approach, i.e. each demand has two node-disjoint paths to provide protection against a single node failure. We formulate new ILP models to find the optimal paths for anycast and unicast connections. To test the proposed approach, we run extensive numerical experiments using CPLEX solver on four example network topologies with different scenarios of number of replica servers, and the proportion between unicast and anycast traffic. Obtained results show the efficiency of our solution in terms of various parameters including cost, path length, resource utilization, and time of computation.","PeriodicalId":202408,"journal":{"name":"2010 14th International Telecommunications Network Strategy and Planning Symposium (NETWORKS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116790847","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}
