The ability to dynamically allocate virtual nodes across distributed physical hosts and even more the live migration of the Virtual Machines which perform such virtual network functions are driving current network infrastructures towards “programmable” networks. To be adopted as a deployable feature on a Carrier's Network, live migration performance need to be analysed and tested. Therefore a compositional modelling approach could provide early measures by evaluating the impact of these new technologies on the performance of Future Network systems. The main contribution of the paper is the definition of a general modelling framework to integrate simple models representing the main components and features of a Future Network architecture. Starting from this model composed by atomic sub-models, we conduct the performance analysis of the live migration of a single Virtual Machine between two hosts located in different networks. The Möbius tool has been used for developing the model as well as for studying its behaviour and performance. Finally, some simulative results are provided in order to show the feasibility of this approach.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124362683","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 context, acoustic communication is the most widespread technology that has demonstrated its effectiveness. Nevertheless, inspite of its multiple advantages, acoustic communication is prone to throughput limitation. Hence, other carriers are needed in order to deal with acoustic communication drawbacks. In a such complex environment, radio and optical communications are promising techniques since they may reach higher throughput. In this paper, we propose a deep study of the most prominent wireless communication methods for underwater environment namely acoustic, radio and optical carriers. Besides, a comparison between the aforementioned carriers is put forward. Based on the carried out study, we design a water monitoring system for pollution detection in river. The aim consists in selecting the most suitable underwater carrier that can possibly enhance the point-to-point communication among underwater sensor nodes.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121999976","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}

Of interest however is that all of these exciting solutions are usually discussed in isolation and rarely do proponents allude to the fact that numerous applications can be deployed simultaneously. Unfortunately most SDN Controllers are incapable of managing multiple applications that require access to the same events notifications. In this paper, we introduce the concept of an Event Arbitration Manager (EAM), a modified event handler that provides mediation between applications on a single SDN controller. We show that the introduction of an event mediation layer between SDN applications would reduce conflicts between multiple applications on the same SDN controller and allows them to respond to controller events messages equally.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115225845","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}

Individual Service Providers join into a predefined Common Channel Signaling network (Backbone IP Routing protocols in the case of the Internet, the SS7/IN network in the case of the PSTN/Mobile Telephony Network) and exchange infrastructure. Once federation relationships are identified through protocols which transit the Signaling network, a Bearer network relationship is established where the user data is transited. This paper describes the workings of the Intercloud system in terms of the details of the Intercloud Federation API, which transits the signaling network, and how this API is used to dynamically provision a Software Defined Network (SDN) based Virtual Private Cloud (VPC) using Virtual Private networks (VPN), creating the federating bearer network for the transparent federation. The Intercloud Federation API is based on a semantic definition of resources, Service Level Agreements (SLA), and Bearer Network Provisioning Metadata.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129855492","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 a typical virtualized and multi-tenant environment, the cloud infrastructure and the hosted cloud services are managed by different administrative entities that may not trust each other. In such a scenario, the cloud service providers might hesitate to disclose operational information to the infrastructure providers. In this paper, we present Encrypted IP (EncrIP), a network-level design consideration for encrypting IP addresses that hides information about which end-systems are communicating in a cloud service, while still allowing packet forwarding with longest-prefix match in commodity routers. Using probabilistic encryption, EncrIP can avoid that an observer can identify what traffic belongs to the same source-destination pairs. Our evaluation results show that EncrIP requires only a few MB of memory on the gateways where traffic enters and leaves the cloud network infrastructure. In our prototype implementation of EncrIP on GENI, which uses standard IP headers, the success probability of a statistical inference attack to identify packets belonging to the same session is less than 0.001%. Therefore, we believe EncrIP presents a practical solution for protecting privacy in multi-tenant, cloud network infrastructure.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116162123","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}

Its innovative concepts, like named content, name-based routing and in-network caching, particularly suit the requirements of the Internet of Things (IoT), interconnecting billions of heterogeneous constrained objects. NDN supports receiver-driven communications and can easily enable IoT pull-based applications, e.g., to monitor sensors and to control actuators. However, NDN cannot natively allow devices to transmit unsolicited data, like alarms or status changes, unless to properly modify the semantics of exchanged packets and the forwarding strategy. In this paper we discuss how NDN can support reliable push-based IoT traffic, through the definition of three schemes conceived to be as much compliant as possible with the NDN tenets, while targeting efficiency in the usage of network and devices resources. A simple analytical framework provides preliminary quantitative insights into the proposed solutions and guidelines for future design.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116500261","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 current I/O network virtualization based on the driver domain is an attractive model since it offers high flexibility and cost-effectiveness. However, it exhibits poor networking performance due to multiple memory transactions between the driver domain and the VM. This paper addresses this challenge by introducing the concept and design of a new I/O subsystem called Next Hop Bridge which identifies the packets belonging to the same flow and processes only the first one of a given flow within the virtual machine. NHB uses a flow table to store the needed information about the packets. Such a switching mechanism allows to considerably avoid unnecessary I/O transactions during the communication between the driver domain and the VM and hence make the VM throughput scale up to line rates.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133231032","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}

They use custom protocol stacks and network virtualization to provide flexible and efficient communication. End user nodes run a framework called NENA to connect to such networks at runtime. The current NENA implementation runs on top of the operating system's network stack and uses the Socket API. It allows to show the flexibility of application-tailored networks but limits NENA's performance. Packet I/O frameworks like Intel's Data Plane Development Kit (DPDK) offer direct access to network interfaces and high performance. So, such a packet I/O framework provides an opportunity to enhance NENA and investigate its performance. In this paper, we present a new implementation of NENA with Intel's Data Plane Development Kit and evaluate its performance. Experiments show that our approach can achieve more than 9 times higher packet rates than a Socket-based implementation and is able to saturate a 10 Gbit/s link using two CPU cores.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"51 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115040547","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 constant threat of viruses, malware, intruders and misconfigured devices has made the task even more difficult. The use of an Intrusion Detection System (IDS) has become a standard defense model in many networks, however they are expensive and difficult to maintain and further complicate a network. This paper introduces a novel approach that integrates a distributed Intrusion Detection System into a Software Defined Network (SDN) and in doing so provides a more scalable security and threat management solution. The core mechanisms that enable SDN to provide an IDS function have been implemented and their performance evaluated. The viability of this approach was evaluated and found to be an effective alternative to the current IDS deployment model.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125086494","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 communication is based on a request/response model where the attention is centered on the content. The user sends interest messages naming the content it desires and the network chooses the best node from which delivers the content. This way for retrieving contents naturally fits a context where users continuously change their location. One of the main problems of user mobility is the intermittent connectivity that causes loss of packets. This work shows how in a Vehicle-to-Infrastructure scenario, the network can exploit the ICN architecture with content pre-distribution to maximize the probability that the user retrieves the desired content. We give an ILP formulation of the problem of optimally distributing the contents in the network nodes and discuss how the system assumptions impact the success probability.
