We envision a dynamic and flexible network that can support a smarter data plane than just simple switches that forward packets. This network architecture needs to support complex stateful routing of flows where processing by network functions (NFs) can dynamically modify the path taken by flows, without unduly burdening or depending on the centralized SDN controller. To this end, we specify a protocol across the different components of an SDN-NFV environment to support the creation of NFs required by a service graph specification, using an orchestrator speaking to an NF Manager running on each host. We take advantage of, and extend, the concept of the SDN controller-to-node protocol (OpenFlow being the most popular) and tagging flows to support complex stateful routing. Output generated by NFs processing packets may be returned to the NF Manager to influence dynamic route changes based on a priori rules defined through a service graph specification provided by network administrators. We envisage the SDN controller setting up these rules based on the output from NFs, the flow specification as well as global tags. By not treating tags as an independent component for routing, we show that we can dramatically reduce the number of tags required across the entire network. Further, by providing the right autonomy in decision making at the NF Manager and the individual NFs in our hierarchical control framework, we significantly reduce the load on the SDN controller.","PeriodicalId":315251,"journal":{"name":"2015 IEEE Conference on Network Function Virtualization and Software Defined Network (NFV-SDN)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129941667","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}

However, today's public clouds provide only a limited view and programmability for tenants that challenges flexible deployment of transparent, software-defined network functions. Moreover, current virtual network functions can't take full advantage of a virtualized cloud environment, limiting scalability and fault tolerance. In this paper we review and evaluate the current infrastructural limitations imposed by public cloud providers and present the design and implementation of GNFC, a cloud-based Network Function Virtualization (NFV) framework that gives tenants the ability to transparently attach stateless, container-based network functions to their services hosted in public clouds. We evaluate the proposed system over three public cloud providers (Amazon EC2, Microsoft Azure and Google Compute Engine) and show the effects on end-to-end latency and throughput using various instance types for NFV hosts.","PeriodicalId":315251,"journal":{"name":"2015 IEEE Conference on Network Function Virtualization and Software Defined Network (NFV-SDN)","volume":"17 36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126055095","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}

However, today most operational VNF clouds are still generally static after their initial instantiation, thus not realizing many of the potential benefits of virtualization and enhanced orchestration. In this paper, we explore a large-scale operational instantiation of a virtual Domain Name System (vDNS) and present an analytical framework and platform to improve its efficiency during normal and adverse network traffic conditions, such as those caused by Distributed Denial-of-Service (DDoS) attacks and site failures. Using dynamic virtual machine instantiation, we show that under normal daily cycles we can run vDNS resolvers at higher target load, increasing the transactional efficiency of the underlying hardware by more than 10%, and improving client latency due to lower recursion rates. We demonstrate a method of reducing reaction time and service impacts due to malicious network traffic, such as during a DDoS event, by automatically redeploying virtual resources at selected nodes in the network. We quantify the tradeoff between spare hardware costs and latency under site failures, taking advantage of SDN controller-based flow redirection. This work is part of AT&T's ongoing network transformation through network function virtualization (NFV), software-defined networking (SDN), and enhanced orchestration.","PeriodicalId":315251,"journal":{"name":"2015 IEEE Conference on Network Function Virtualization and Software Defined Network (NFV-SDN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131198424","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 two-phase update is underspecified on two matters: 1) how to detect when the last packet of the old rule set has left the network and therefore exactly when to delete the old rules 2) recoverability of the update. Recoverability ensures that those updates for which the two-phase algorithm is not completely executed do not change the semantics of those updates for which the algorithm is completely executed. This paper examines the failures that can occur during an update and how to handle a subset of those failures. It proposes an algorithm, enhancing the two-phase update to handle deletion of old rules and recoverability. It also specifies how to effectively use a software cache to supplement the TCAM, during an update. The paper extends the same algorithm for per-flow consistent updates, using a restricted number of exact-match rules for existing flows and specifying when to delete the exact-match rules. The two algorithms are also specified for switches that do not support a software cache. The paper also analyzes the algorithms quantitatively, identifying the parameters of interest and what they depend upon.","PeriodicalId":315251,"journal":{"name":"2015 IEEE Conference on Network Function Virtualization and Software Defined Network (NFV-SDN)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131206042","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}
