Moving towards Network Functions Virtualization (NFV), virtualized middlebox appliances can be more flexibly instantiated and dynamically chained, making troubleshooting even more difficult. To guarantee carrier-grade availability and minimize outages, operators need ways to automatically verify that the deployed network and middlebox configurations obey higher level network policies. In this paper, we first define and identify the key challenges for checking the correct forwarding behavior of Service Function Chains (SFC). We then design and develop a network diagnosis framework that aids network administrators in verifying the correctness of SFC policy enforcement. Our prototype - SFC-Checker can verify stateful service chains efficiently, by analyzing the switches' forwarding rules and the middleboxes' stateful forwarding behavior. Built on top of the network function models we proposed, we develop a diagnosis algorithm that is able to check the stateful forwarding behavior of a chain of network service functions.","PeriodicalId":448203,"journal":{"name":"2016 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115507861","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}

Being able to cope with on-demand traffic increase is one of the key principles taken from the Cloud Computing domain and extended to the Telco one by the ETSI Network Function Virtualization (NFV) initiative. However, due to the novelty of this paradigm in the Telco domain, the landscape of fully-interoperable frameworks is rather limited and even more complex is their extensibility for supporting new functionalities. None of the existing solutions nowadays provide mechanisms for dynamically adapt the NS topology based on their Runtime Key Performance Indicators (KPIs), supporting the requirements requested by the ETSI NFV specification. Therefore, this article presents an Autoscaling Engine (AE) capable of dynamically adapting a NS based on policies provided by the Operator and integrated in the ETSI NFV information model. Its design has been realized considering the NFV requirements, and has been integrated in the ETSI NFV Architecture as additional functional element. Its implementation is part of an existing NFV-compliant framework, Open Baton, and made available to the community as open source. An evaluation of the implemented concept shows that the proposed solution increases the reliability, stability and resource efficiency of NSs.","PeriodicalId":448203,"journal":{"name":"2016 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115588254","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}

SFC exploits Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies to achieve the creation, modification and deletion of SFC in a cost efficient and rapid way. However, during the runtime phase, SFs are exposed to the risk of failures, which results in an end-to-end failure at the application level. For this reason, this paper introduces the concept of a resilient SFC Orchestrator capable of deploying SF Chains following the ETSI NFV architectural model, as well as controlling the runtime phase rerouting the traffic to a different path in case of appearing faults. Furthermore, the concept is exemplified as an addition to the current NFV architecture and evaluated in a NFV environment making use of the Fraunhofer FOKUS Open Baton toolkit in an OpenStack and OpenDayLight based environment. Finally, the measured results show that the Service Function Path (SFP), and therefore their provided services, can be recovered in a few seconds.","PeriodicalId":448203,"journal":{"name":"2016 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123035643","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}

While the benefits of NFV such as cost reduction and increased agility are well understood, doubts still exist on whether a software implementation can match up to the high performance that hardware appliances deliver. In this context, network operators would benefit from frameworks that monitor performance and identify bottlenecks in Virtual Network Function (VNF) implementations obtained from vendors. While several techniques already exist to identify performance issues in cloud-based applications, most of them either use hardware resource utilizations to identify hot-spots (making them incapable of detecting non-hardware performance bottlenecks) or rely on application specific measurements (which may not be exposed by VNFs to vendors always). This paper describes NFVPerf, a performance monitoring and bottleneck detection tool for NFV. NFVPerf works as part of a cloud that hosts a NFV deployment, and takes a configuration file specifying the basic architecture of the VNF as input. It sniffs packets on all VM-to-VM communication paths, computes per-hop throughputs and delays, and uses these “black-box” measurements alone to identify performance bottlenecks (including software bottlenecks) in real time, without requiring any instrumentation of the VNF. Further, NFVPerf can be customized to any VNF implementations with just configuration changes. Our evaluation of NFVPerf shows that it can monitor performance and identify bottlenecks in an NFV deployment, with high accuracy and minimal overhead. We believe that a system like NFVPerf would form a great addition to cloud management systems in the era of NFV.","PeriodicalId":448203,"journal":{"name":"2016 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)","volume":"391 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125148797","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 order to fulfill the extremely low latency requirement in combination with ultrahigh availability and reliability, we need novel approaches, for example to dynamically move network “capabilities” close to the users. This requires more flexibility, automation and adaptability to be added to the networks at different levels and operation planes. The key enabler of the novel features is network softwarization provided by NFV and SDN techniques. In this paper, we focus on a central component of the orchestration plane which is responsible for mapping the building blocks of services to available resources. Our main contribution is twofold. First, we propose a novel service graph embedding algorithm which is able to jointly control and optimize the usage of compute and network resources efficiently based on greedy heuristics. Besides, the algorithm can be configured extensively to obtain different optimization goals and trade-off running time with the search space. Second, we report on our implementation and integration with our proof-of-concept orchestration framework ESCAPE.

Due to decoupled control and data plane, Software Defined Networks (SDN) can handle these increasing number of attacks by blocking those network connections at the switch level. However, the challenge lies in defining the set of rules on the SDN controller to block malicious network connections. Historical network attack data can be used to automatically identify and block the malicious connections. There are a few existing open-source software tools to monitor and limit the number of login attempts per source IP address one-by-one. However, these solutions cannot efficiently act against a chain of attacks that comprises multiple IP addresses used by each attacker. In this paper, we propose using machine learning algorithms, trained on historical network attack data, to identify the potential malicious connections and potential attack destinations. We use four widely-known machine learning algorithms: C4.5, Bayesian Network (BayesNet), Decision Table (DT), and Naive-Bayes to predict the host that will be attacked based on the historical data. Experimental results show that average prediction accuracy of 91.68% is attained using Bayesian Networks.","PeriodicalId":448203,"journal":{"name":"2016 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127989862","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}
