YouTube traffic analyses were carried out in the perspective of video clip category and duration, in order to understand their impact on the potential local network caching gains. To the best of our knowledge, this is the first time systematic analysis of YouTube traffic content in the perspective of video clip category and duration in a residential broadband network. Our results show that the requested YouTube video clips from the end users in the studied network were imbalanced in regarding the video categories and durations. The dominating video category was Music, both in terms of the total traffic share as well as the contribution to the overall potential local network caching gain. In addition, most of the requested video clips were between 2-5 min in duration, despite video clips with durations over 15 min were also popular among certain video categories, e.g. film videos.","PeriodicalId":143986,"journal":{"name":"2013 Fourth International Conference on the Network of the Future (NoF)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115066408","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}

Several studies in the field have been made by different teams, but the allocation of physical resources remains an open problem in the field of network virtualization. We identified this problem as a graph matching problem. We express and solve it like a Constraint Satisfaction Problem (CSP). Our CSP model includes Qos requirements and energy saving. To our knowledge, no previous work used CSP approach and combined Qos and Green aspects to allocate resources.","PeriodicalId":143986,"journal":{"name":"2013 Fourth International Conference on the Network of the Future (NoF)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121739154","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}

It is suitable to several energy critical applications suffered from limited resources. For this reason, many studies proposed energy-efficient solutions, however, they may waste energy caused by the frequent packet collisions since they do not consider the contentions in multi-coordinator environments. In response, we proposed a new contention resolution scheme to enhance the energy efficiency by reducing the contention among nearby coordinators. In the proposed scheme, the coordinators exchange schedules based on the collected information. It leads that the coordinators isolate the superframe duration by staggering own beacon transmission. This can mitigate significant contentions among burst packets at the beginning of the superframe to reduce energy consumption. Simulation results show that the proposed scheme outperforms existing solutions.","PeriodicalId":143986,"journal":{"name":"2013 Fourth International Conference on the Network of the Future (NoF)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115624526","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}

It enables network providers to select appropriate network services according to application needs. In addition, virtualization technologies are used by the SDN (Software Defined Networking) paradigm to decouple control plane from forwarding plane. The convergence of SDN and network virtualization allows to conceive on-demand virtual network by personalizing its services and even its control plane. In this context, a key challenge faced by network providers is how to place virtual network components while ensuring QoS requirements of application flows. To surpass this issue, we propose in this paper a constraint placement language used when mapping virtual network components (node and links) over the substrate infrastructure. Particularly, we define network constraints including QoS, isolation, security, affinity, anti-affinity, etc. in the node-level and link-level.","PeriodicalId":143986,"journal":{"name":"2013 Fourth International Conference on the Network of the Future (NoF)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114196155","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 an NVE, infrastructure providers (InPs) provide service providers (SPs) with virtual networks (VNs) using the InPs' substrate resources for the SPs' application services. Service providers have flexible requirements of topology, quality of service (QoS), and their dynamic changes on VNs. To meet all these requirements, traditional approaches based on performance guarantee relying only on InPs are inefficient and sometimes infeasible because they result in significant operational cost. We propose an architecture in which SPs can select appropriate resources from available resources and dynamically use the allocated resources depending on their application characteristics and user situations to meet their demands. In the proposed architecture, SPs can improve VN performance through resource control, and InPs are not required to have any performance guaranteed networks. Therefore, the proposed architecture can balance QoS and resource efficiency. We also present the basic design of the proposed architecture and show use cases and a prototype implementation using OpenFlow technologies.","PeriodicalId":143986,"journal":{"name":"2013 Fourth International Conference on the Network of the Future (NoF)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123977657","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}

Even though most of telematics services are delivered via cellular network between a base station and a vehicle in the current stage, the advent of DSRC/WAVE standard in vehicular communications will change the paradigm of telematics applications and create a new demand for telematics services. However, DSRC/WAVE still utilizes TCP/IP protocol which is considered inappropriate for dynamic network environment like vehicular networks. To resolve the inherent limitations of TCP/IP protocol, we propose to adopt Content-Centric Networking (CCN) for DSRC/WAVE protocol stack and suggest its system architecture, naming structure and the naming examples for telematics services. We also provide a proper data request cycle and the practicality of CCN caching mechanism based on the understanding of current telematics services.","PeriodicalId":143986,"journal":{"name":"2013 Fourth International Conference on the Network of the Future (NoF)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122414924","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}

Since distinguishing between unwanted packet and active packet is not feasible at MAC layer, the power management mechanism is equally affected by unwanted packets (packets with unreachable destination port).

It forces unwanted packet to be delivered through the “Hidden Tail-time” that is an additional awake time immediately before smartphone switches from awake-state to sleep-state. Thus, unwanted packets never affect the PSM mechanism. Our proposed scheme improves power saving by up to 67% under mixed setting of unwanted packet and active packet.","PeriodicalId":143986,"journal":{"name":"2013 Fourth International Conference on the Network of the Future (NoF)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122637427","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, the potential advantage of in-network caching does not be fully unleashed in the original sketch of CCN. Network coding improves performance by introducing computing into current Internet. This paper proposes CCN-NC (Content-Centric Networking with Built-in Network Coding). In this architecture, in-network caching is collaborating with network coding to achieve multisource dissemination at network level. Firstly, this paper addresses some key challenges of CCN-NC's design, such as format of data message, naming, forwarding strategy and communication scheme. Then, we validate the architecture in the final part of the paper. The experiment results show that CCN-NC improves throughput by 35.5% compared to the current TCP/IP and by 17.4% compared to original CCN.

These capabilities are often realized in multiple system layers, with the control logic needed for a specific capability residing in the application agents interfacing with the underlying network system services. We employ a software cybernetics approach, where an intelligent physical system module (IPW) embodies the core adaptation functionality to respond to the changing environment conditions and user inputs. The IPW exhibits an intelligent behavior over a limited operating region of the system. And, it is augmented by a supervisory module (ICW) that houses external feedback loops for situational assessment of the changing environment conditions. Our autonomic management of various hierarchical control loops comes under the ambit of Cyber-Physical Systems (CPS). The ICW patches the IPW with suitable control parameters and rules/procedures when the system operating conditions change. The paper illuminates our concept of IPW with a software engineering-oriented case study of multi-source video transfer over a bandwidth-limited network path.","PeriodicalId":143986,"journal":{"name":"2013 Fourth International Conference on the Network of the Future (NoF)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128403834","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}
