Currently, access networks rely upon centralized packet multiplexers to perform network and protocol processing functions, manage subscriber state, and aggregate network traffic. On the other hand cloud-based applications are built around public or private clouds, web-based tools and resources executed on centralized infrastructure accessible over core networks and the Internet. However, this monolithic model can lead to capacity and space bottlenecks, compromise network services because of a lack of common feature sets, and limit the revenue that data services can produce for operators. This paper proposes a novel fiber access network infrastructure that can support distributed processing and function virtualization exploiting the HYDRA (HYbriD long-Reach fiber Access network) architecture. The proposed scheme leads to a higher degree of node consolidation and network and service convergence. We discuss how logical network virtualization and efficient resource orchestration for flexible service creation and delivery can be achieved describing indicative future services that could exploit the enhanced functionality and distributed processing paradigm.","PeriodicalId":162582,"journal":{"name":"2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124923813","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 this scenario, a major topic is the use of ad hoc h/w accelerators, in particular to provide the network with general purpose High Performance Computing capabilities, whose application has been so far limited to few highly specialized contexts, such as graphics or scientific computing. However, the use of h/w acceleration is generally considered in contrast with the main NFV concepts, and a major obstacle towards network programmability. This paper argues that, on the contrary, h/w acceleration and virtualization technologies are fully compatible, and together can greatly enhance the network infrastructure. In particular, the use of Graphic Computing Units in Virtual Network Functions is analyzed, and their flexible management is considered, within the innovative NFV architecture designed by the EU FP7 T-Nova project.","PeriodicalId":162582,"journal":{"name":"2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123668010","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}
