{"title":"Mobility Support in Slice-based Network Control for Heterogeneous Environments (MOBISLICE 2020)","authors":"Mobislice, Daniel Corujo","doi":"10.1109/nfv-sdn50289.2020.9289915","DOIUrl":"https://doi.org/10.1109/nfv-sdn50289.2020.9289915","url":null,"abstract":"Network slicing has been standing as one of the key enabling technologies for the upcoming 5th Generation of Telecommunications. Alongside other important technologies, such as NFV, SDN and MEC, its contributions to isolated network provisioning in a more dynamic and flexible way are being pursued in different industry and academia arenas throughout the world. Nonetheless, considering the wide range of foreseen enhanced use cases (not only in scope of 5G but also Beyond-5G), slicing aspects have been mostly targeting either enhancements at the radio level, or the integration of cloud resourcing capabilities for supporting network operation at the core and/or the edge. As such, there is a wide gap related with the impact that such slicing-based procedures will exert over mobility management processes for seamless mobility support while the devices, network or services move both physically (i.e., change their network point of attachment) as well as virtually (i.e., between slices). MOBISLICE (Mobility Support in Slice-based Network Control for Heterogeneous Environments) is a workshop dedicated to this issue, it’s solutions, their deployment and exploitation. This journey began in 2018 as a workshop collocated with IEEE NFV SDN, with the first workshop dedicated to foster the ideas of slice-based designs and technologies in mobile scenarios and assess their impact, proposing solutions and enhancements to their efficient, dynamic and elastic support. In 2019, the second workshop addressed the complexities of applying mobile-enabled slices in different environments, ranging from massive scale machine type communications to full-fledged mobile broadband and others. Finally, in 2020, the latest edition of MOBISLICE III focused on bringing forth first assessments, technical planning and supportive technologies evolutions, for the validation of network slice deployments in real and experimental scenarios within and outside the lab. It took a deep look into on-going research and industrial efforts not only featuring ICT players (e.g., telcos, system providers, vendors) but also verticals (as the network slice consumers), which are pursuing joint technical solutions where the mobility of slices has a presence. Additionally, it addressed the underlying technical innovations and tools over existing experimental infrastructure, to support these real experiments, trials, laboratorial work and scalability models/assessment. It is with great pleasure that we share with you the findings proposed by our authors, extensively reviewed by our panel of experts, certain that the considerations therein will be of great value and contribution to your knowledge in the area.","PeriodicalId":283280,"journal":{"name":"2020 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134187691","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}

FlowBlaze architecture for data planes has shown that Extended Finite State Machines can be efficiently supported in hardware enabling stateful packet processing at line-rate through a powerful abstraction for application programming. A recent proposal tries to simplify the development of FlowBlaze applications on top of its hardware and software prototypes with a domain-specific language, however, the community is currently missing a fast prototyping environment to experiment with EFSM-based applications using the P4 language, recognized as the de-facto standard for data plane programmability. This paper presents FlowBlaze.p4, a library developed in P4 that implements a FlowBlaze executor. The library maps the FlowBlaze elements into P4-native components and can be integrated into existing P4 programs. FlowBlaze.p4 can be easily configured by means of five configuration parameters. A GUI is also provided to enable the developer to simply draw the EFSM, skipping its manual mapping to the corresponding low-level run-time configuration. We present a functional evaluation of our library with two use cases that demonstrate how easily and quickly FlowBlaze.p4 and the GUI can be used to develop new stateful data plane applications.","PeriodicalId":283280,"journal":{"name":"2020 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123405871","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}

Network slicing is considered as the key enabler for achieving this goal. Although there is some progress in applying and implementing network slicing in the context of 5G, the security and performance of network slicing still have many open research questions. In this paper, we propose the first OSM-WireGuard framework and its lifecycle. We implement the WireGuard secure network tunneling protocol in a 5G network to provide a VPN-as-a-Service (VPNaaS) functionality for virtualized network functions. We demonstrate that OSM instantiates WireGuard-enabled services up and running in 4 min 26 sec, with potential the initialization time to go down to 2 min 44 sec if the operator prepares images with a pre-installed and up-to-date version of WireGuard before the on-boarding process. We also show that the OSM-WireGuard framework provides considerable enhancement of up to 5.3 times higher network throughput and up to 41% lower latency compared to OpenVPN. The reported results show that the proposed framework is a promising solution for providing traffic isolation with strict latency and throughput requirements.","PeriodicalId":283280,"journal":{"name":"2020 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121409685","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 application of Distributed ledger technologies (DLTs) for the federation procedures to enable private, secure and trusty interactions between undisclosed administrative domains.

Baras","doi":"10.1109/NFV-SDN50289.2020.9289885","DOIUrl":"https://doi.org/10.1109/NFV-SDN50289.2020.9289885","url":null,"abstract":"With the emergence of network function virtualization (NFV), and software-defined networking (SDN), the realization and implementation of service function chains (SFCs) have become much easier. An SFC is an ordered set of interconnected virtual network functions (VNFs). NFV allows for decoupling the network functions from proprietary hardware realizing a software-based implementation of VNFs on commodity hardware, and SDN decouples the network control from its forwarding logic allowing for a more flexible and programmable traffic routing among the VNFs. The SFC embedding problem (i.e. placement of SFCs on a shared substrate and establishing the corresponding traffic routes between the VNFs), has been extensively studied in the literature. In this paper, we extend a previous work on trust-aware service chain embedding with generalizing the role of trust by incorporating the trustworthiness of the service network links and substrate network paths into the SFC embedding decision process. We first introduce and formulate the path-based trust-aware service chain embedding problem as a mixed integer-linear program (MILP), and then provide an approximate model based on selecting - shortest candidate substrate paths for hosting each virtual link, to reduce the complexity of the model. We validate the performance of our methods through simulations and conduct a discussion on evaluating the methods and some operation trade-offs.","PeriodicalId":283280,"journal":{"name":"2020 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116993119","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}

These NIDS perform better when they can monitor all the traffic traversing through the network like when being deployed on a Software-Defined Network (SDN). Because of the inability to detect zeroday attacks, signature-based NIDS which were traditionally used for detecting malicious traffic are beginning to get replaced by anomaly-based NIDS built on neural networks. However, recently it has been shown that such NIDS have their own drawback namely being vulnerable to the adversarial example attack. Moreover, they were mostly evaluated on the old datasets which don't represent the variety of attacks network systems might face these days. In this paper, we present Reconstruction from Partial Observation (RePO) as a new mechanism to build an NIDS with the help of denoising autoencoders capable of detecting different types of network attacks in a low false alert setting with an enhanced robustness against adversarial example attack. Our evaluation conducted on a dataset with a variety of network attacks shows denoising autoencoders can improve detection of malicious traffic by up to 29% in a normal setting and by up to 45% in an adversarial setting compared to other recently proposed anomaly detectors.","PeriodicalId":283280,"journal":{"name":"2020 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133427388","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}
