Network densification using heterogeneous networks supported by Cloud-RAN is one of the core concepts in terms of physical resources. The system achieves increased capacity by reducing the number of devices (commonly refered to as user equipment - UE) connected to any individual cell. Cloud-RAN decouples the baseband processing from the radio units, allowing the processing power to be pooled at a central location thus reducing the required redundancy. The decoupling also supports innovation in many other RAN technologies by simplifying intercell coordination. While Cloud-RAN differs significantly from traditional base station architectures, interactions with the core network do not reflect these differences. We argue that there is a strong need for an intermediate stage that will reconcile the core network and Cloud-RAN. In this paper we propose a virtual network architecture for Cloud-RAN base stations that will allow us to present the core network with an abstracted view of the physical network. By logically grouping macro cells with collocated small cells we can provide the core network with a simplified overview, reducing signalling overhead. Meanwhile, low latency decisions, such as cell load balancing and interference management, can be made entirely within the Cloud-RAN base station. We present practical applications of the proposed scheme and assess its interoperability with other improvements to the wider infrastructure proposed in related works. The principles presented in this paper lend themselves to evolving key concepts and themes for future 5G networks and beyond.","PeriodicalId":103165,"journal":{"name":"2014 Third European Workshop on Software Defined Networks","volume":"69 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":"124229679","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}

Multi-tenancy in OpenFlow networks is an effective method to supporting a clean-slate network design, because the cost-effectiveness is improved by the sharing of substrate networks. To guarantee the programmability of OpenFlow for tenants, a complete flow space (i.e., header values of the data packets) virtualization is necessary. Wide-area substrate networks typically have multiple administrators. We therefore need to implement a flow space virtualization over multiple administration networks. In existing techniques, a third party is solely responsible for managing the mapping of header values for flow space virtualization for substrate network administrators and tenants, despite the severity of a third party failure. In this paper, we propose an AutoVFlow mechanism that allows flow space virtualization in a wide-area networks without the need for a third party. Substrate network administrators implement a flow space virtualization autonomously. They are responsible for virtualizing a flow space involving switches in their own substrate networks. Using a prototype of AutoVFlow, we measured the virtualization overhead, the results of which show a negligible amount of overhead.","PeriodicalId":103165,"journal":{"name":"2014 Third European Workshop on Software Defined Networks","volume":"26 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":"127808115","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 control plane needs to be able to fully utilize growing capabilities of modern networking hardware and its diversity. In this paper we propose a new hardware abstraction for various network devices (network processors, optical devices and access devices). The first goal of this proposal is to expose advanced programmability capabilities of network processors and software switches. The second goal of our proposal is to extend the concept of the network node programmability by giving a possibility to dynamically check capabilities supported by a particular network device. The third goal of this paper is to introduce programming language which use new-defined API to Programmable Abstraction of Datapath (PAD) for different kind of network devices. The presented solution ensures therefore flexibility and adaptability of the new programmable functions to specific requirements of a device. The proposed solution creates a unified way of controlling and configuring a variety of families of network devices from optical switches to x86-based appliances.","PeriodicalId":103165,"journal":{"name":"2014 Third European Workshop on Software Defined Networks","volume":"488 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":"122752423","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}

To this aim, one of the most suitable approaches is the one which takes advantage of the emerging paradigm of Software-Defined Networking (SDN) and OpenFlow, its de-facto standard. Several virtualization frameworks have been proposed in the last few years, however, they are either based on proxy-based solutions that raises scalability and robustness issues (FlowVisor), or they rely on a simplified view of the data path (generally based on Open vSwitch instances) that have little chances to be adopted in production network settings. This paper presents a novel OpenFlow-based network virtualization mechanism exploiting a recent open-source data path project named extensible Data path Daemon (xDPd), the proposed multi-platform data path is based on a robust distributed virtualization architecture that is able to run on multi-version OpenFlow switch network scenarios, has a minimal overhead from a performance point of view and can be easily ported on several hardware platforms via xDPd libraries.","PeriodicalId":103165,"journal":{"name":"2014 Third European Workshop on Software Defined Networks","volume":"27 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":"130365146","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}
