In order to dynamically direct traffic flows between respective network elements, Software Defined Networking (SDN) can be seen as one enabler. In this paper, we focus on mobile core network nodes such as the MME, HSS, S- and P- Gateway as standardized for the LTE Evolved Packet Core (EPC). One straightforward solution for a virtualized EPC architecture would be to move all EPC network nodes completely into a data center and handle the data traffic via SDN-enabled switches. However, this solution would keep the conventional monolithic architecture unchanged. A possible split in the EPC functionality between a centralized data center and operator's transport network elements could be needed to provide the desired flexibility, performance and TCO reduction. Therefore, we have analyzed the EPC nodes and classified their functions according to their impact on data-plane and control-plane processing. We propose a mapping for these functions on four alternative deployment frameworks based on SDN and OpenFlow (OF). In addition, we investigate the current OF implementation's capability to realize basic core operations such as QoS, data classification, tunneling and charging. Our analysis shows that functions, which involve high data packet processing such as tunneling, have more potential to be kept on the data-plane network element, i.e. realized by an OpenFlow Switch. We argue for an enhanced OF network element NE+, which contains additional network functions next to the basic OpenFlow protocol.","PeriodicalId":6455,"journal":{"name":"2013 IEEE SDN for Future Networks and Services (SDN4FNS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80807337","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}

This is related to a plethora of requirements at the core network part such as energy costs, capital investment challenges and skills necessary to design, integrate and operate increasingly complex hardware- based appliances. At the end user side, the evolution of the Internet of Things envisions to increase the number of connections by yet another order of magnitude (from ~10 billion currently connected \"Things\"), bringing unprecedented challenges in network scalability, resource efficiency, and privacy considerations. This paper tackles the previous challenges under the prism of network function virtualization focusing on the following use cases: Software Defined Networking controlled wireless integration service, virtual cell management, and sensor networks virtualization. We discuss how the different facets of Virtualization promise to alleviate or resolve some of these challenges, acting as a catalyst for the realization of disruptive networking paradigms, both in the core network and in the end-user side.","PeriodicalId":6455,"journal":{"name":"2013 IEEE SDN for Future Networks and Services (SDN4FNS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76971060","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 elements implement complex network functions like firewalls, NATs, DPI, traffic scrubbing, etc. The product is a quite complex and rigid internetworking system in which network administrators and users cannot easily determine what is happening to traffic flows as they go toward destinations. SDN research and programmable network functions for flow processing and virtualization are unlocking the current scenario, though most of the COTS products generally support network functions only for virtual L2 switching over IP networks (e.g. VXLAN, GRENV, STT) and LAN based flow pinpointing. This paper presents a different perspective for implementing flow processing via distributed SDN controllers and inter-platform signaling. The distributed end-to-end service provisioning among adjacent flow processing platforms is implemented via a signaling framework in which the different actions/functions to be executed by each platform are described in a generic Flow Processing Route (FPR) object. The FPR is exchanged among the SDN controllers over the end-to-end network service path and contains information on routing rules and local flow processing actions to be instantiated at the different platforms. The proposed signaling architecture has been designed and implemented in the FP7-ICT CHANGE project. This paper reports on the key signaling architectural aspects and the developed signaling prototype.","PeriodicalId":6455,"journal":{"name":"2013 IEEE SDN for Future Networks and Services (SDN4FNS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87034272","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 disciplines of Traffic Engineering (TE) and Network Management (NM) have addressed these domains with static, semi-automatic and pure self-organizational approaches. Most of the existing approaches usually either relax the problem by taking strong assumptions on the problem instances or by only taking a small portion of the solution space into consideration, thus losing the chance of proving any global optimality gaps. The emerging cloud hosted flexible telecommunication system addressed by the industry nowadays puts new requirements on TE and ND. Current, telecommunication networks are often statically deployed and over-provisioned to cover pre-defined peak data rates, but are inflexible to adapt to dynamic network load situations. This paper presents novel dynamic Traffic Engineering (TE) and adaptive Network Management (NM) approaches for software defined telecommunication networks, which reduce Operational - and Capital Expenditures (OPEX/CAPEX), but also enhance the level of flexibility and elasticity at the same time.","PeriodicalId":6455,"journal":{"name":"2013 IEEE SDN for Future Networks and Services (SDN4FNS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72790847","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}

Parallely, testbeds and experimental facilities are widely regarded as the fundamental step-stone to future \"clean slate\" networking. However, designing and building experimental facilities can hardly be considered a trivial step for either researchers and practitioners. Scale, flexibility, and ease of use are just some of the challenges faced by a testbed designer. These considerations are at the base of efforts such as GENI in USA, AKARI in Japan, FEDERICA, NOVI and OFELIA in Europe which provide federated and open facilities for the Future Internet research agenda. Albeit the importance of such facilities is unquestioned, today there is still a dearth of testbed exploiting SDN and NFV concepts in the wireless networking domain. In this paper we present EmPOWER an experimental testbed which aims at filling this gap by offering an open platform on top of which novel concepts can be tested at scale. The EmPOWER testbed is composed by 30 nodes and is currently used by both undergraduate and graduate students at the University of Trento and by the research staff at CREATE-NET.","PeriodicalId":6455,"journal":{"name":"2013 IEEE SDN for Future Networks and Services (SDN4FNS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80698714","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}
