It would be appealing to include substantial parts of the network under OF control but until recently this implied replacing much of the hardware with OF enabled versions. There are some cases, such as access networks in which the benefits could be considerable but deal with a great amount of legacy equipment that is difficult tore place. In this case an alternative method of enabling Odon these devices would be useful. In this paper we describe an architecture and software which could enable OF on many access technologies with minimal changes. The software has been written and tested on a Gigabit Ethernet Passive Optical Network(GEPON). The approach is engineered to be easily ported to any access technology with minimal requirements made on that hardware.","PeriodicalId":103165,"journal":{"name":"2014 Third European Workshop on Software Defined Networks","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123274398","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}

Commercial SDN controller solutions incorporate fault tolerance, but there has been little discussion in the SDN community on the design of such systems and the tradeoffs involved. To fill this gap, we present a by-construction design of a fault-tolerant controller, and materialize it by proposing and formalizing a practical architecture for small to medium-sized networks. A central component of our design is a replicated shared database that stores all network state. Contrary to the more common primary-backup approaches, the proposed design guarantees a smooth transition in case of failures and avoids the need of an additional coordination service. Our preliminary results show that the performance of our solution fulfils the demands of the target networks. We hope this work to be a first step in what we consider a necessary discussion on how to build robust SDNs.","PeriodicalId":103165,"journal":{"name":"2014 Third European Workshop on Software Defined Networks","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126509858","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}

Unfortunately, the abstraction process may hide important information about the devices that finally impacts on the network operations. Although SDN implementations, like OpenFlow, already account for some device specific properties, we believe that other important ones have been so far overlooked. To this regard, we focus on the switches' performance at handling control messages and on how this may affect the control plane design. To support our discussion, we provide theoretical examples and simulation-based experiments. We conclude that accounting for switches performance at handling control messages is a crucial step in the design of advanced SDN control plane features.","PeriodicalId":103165,"journal":{"name":"2014 Third European Workshop on Software Defined Networks","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130391105","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}

More specifically, we exploit the network programmability of OpenFlow to match and handle traffic on a per-flow level, in order to preserve normal operation of the victim, while pushing the mitigation process upstream towards the edge of the network. To this end, we implemented and evaluated a sketch-based anomaly detection and identification mechanism, capable of pinpointing the victim and remotely triggering the mitigation of the offending network traffic. The evaluation is based on the combination of datasets containing real DDoS attacks and normal background traffic from an operational university campus network. Our results demonstrated that the proposed approach succeeds in identifying the victim of the attack and efficiently filtering the malicious sources.","PeriodicalId":103165,"journal":{"name":"2014 Third European Workshop on Software Defined Networks","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128776613","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}

SDN provides an abstraction model of the Forwarding Plane and separates it from the Control Plane using open APIs. In parallel, major telecom operators have embarked on an effort to bring the advantages of virtualization to carrier network infrastructures. Part of this effort was invested in establishing the Network Function Virtualization (NFV) Industry Specification Group (ISG) at the European Telecommunications Standards Institute (ETSI). The NFV goal is to define how Network Functions (ranging from firewalls and load-balancers to routers and access elements) can be virtualized and run as software on high-volume servers instead of specialized hardware. This paper treats SDN and NFV as complementary concepts that together form a bigger picture in the domain of future carrier networks and discusses the complete lifecycle of such a network. In this context we present how ForCES can be used as the foundation for SDN-enhanced NFV and describe the blueprint for the Proof of Concept (PoC) prototype which has been introduced to the NFV ISG. A key goal of this paper is to concisely position carrier NFV and SDN activities under a unified framework.","PeriodicalId":103165,"journal":{"name":"2014 Third European Workshop on Software Defined Networks","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130380781","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}
