However, to deploy a software-defined Wi-Fi network today, one has to rely on research prototypes with availability, documentation, hardware requirements, and scalability issues. To alleviate this situation, we demonstrate two simple techniques to bring SDN functionality to existing Wi-Fi networks and discuss their benefits and short-comings. Researchers can use our techniques to convert their existing Wi-Fi testbeds into software defined Wi-Fi testbeds. Our two techniques thus significantly lower the barrier-to-entry for deploying software-defined Wi-Fi networks.","PeriodicalId":284960,"journal":{"name":"Proceedings of the 2016 ACM SIGCOMM Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121628411","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, introducing SDN at the inter-domain level might also lead to misconfigurations with potential to negatively impact on the Internet. Simulators are a popular approach to verify network behaviour and test applications before going into production. In the case of SDN, the available options do not scale for large scale networks nor high traffic loads. In this paper we propose a new simulator to foster SDN research and improve our understanding on the impact of the new use cases over the traffic flow. A simulation tool capable of efficiently reproducing large scale networks, high traffic loads, and policies, by abstracting the interactions between switches and controllers of the SDN network.","PeriodicalId":284960,"journal":{"name":"Proceedings of the 2016 ACM SIGCOMM Conference","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129025155","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, STP has significant shortcomings -- chiefly, that it throws away network capacity by removing links, and that it can be relatively slow to reconverge after topology changes. In recent years, attempts to rectify these shortcomings have been made by either making L2 look more like L3 (notably TRILL and SPB, which both incorporate L3-like routing) or by replacing L2 switches with \"L3 switching\" hardware and extending IP all the way to the host. In this paper, we examine an alternate point in the L2 design space, which is simple (in that it is a single data plane mechanism with no separate control plane), converges quickly, delivers packets during convergence, utilizes all available links, and can be extended to support both equal-cost multipath and efficient multicast.","PeriodicalId":284960,"journal":{"name":"Proceedings of the 2016 ACM SIGCOMM Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128019931","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}

Traditional traffic-engineering methods can hardly cope with these surges, as they are unpredictable by nature. Consequently, networks either have to be over-provisioned, which is expensive and wastes resources, or risk to periodically incur congestion, which infuriates customers. This demonstration shows how Fibbing can improve network performance and preserve users’ quality of experience when accessing video streams, by implementing a fine-grained load-balancing service. This service leverages two unique features of Fibbing: programming per destination load-balancing and implementing uneven splitting ratios.","PeriodicalId":284960,"journal":{"name":"Proceedings of the 2016 ACM SIGCOMM Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132672390","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}

OFS components, e.g. flow table, meter table, counters, have to compete for the limited fast memory resource. As a result, only a few counting functions are defined as mandatory in the OFS specification, although a lot of SDN proposals depend on a detailed states collected by the optional counters in the specification. This fact motivates us to rethink the way to maintain counters in the OFS. We propose a new architecture called CACTI, which only consumes several registers in the fast path and moves the completed counters into the on chip RAM like cache in the slow path processor. Theoretical analysis and experiments on the prototype system demonstrated the efficiency of our architecture: CACTI is capable to achieve the throughput of 29.4-39.7M pps packets per second (pps). No RAM resource is needed any more in the fast path, instead, CACTI consumes only 0.24-0.54% Look-Up Table and 0.35-0.43% flip-flops compared with the entire FPGA-based OFS design in the fast path, and the unused CPU cache in the slow path.","PeriodicalId":284960,"journal":{"name":"Proceedings of the 2016 ACM SIGCOMM Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133595272","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 preliminary evaluations show that LISP generally has a reliable performance, compared with the existing Internet.

Little, however, is known about failures large content providers are susceptible to, and what mechanisms they employ to ensure high availability. From a detailed analysis of over 100 high-impact failure events in a global-scale content provider encompassing several data centers and two WANs, we quantify several dimensions of availability failures. We find that failures are evenly distributed across different network types and planes, but that a large number of failures happen when a management operation is in progress within the network. We discuss some of these failures in detail, and also describe our design principles for high availability motivated by these failures, including using defense in depth, maintaining consistency across planes, failing open on large failures, carefully preventing and avoiding failures, and assessing root cause quickly. Our findings suggest that, as networks become more complicated, failures lurk everywhere, and, counter-intuitively, continuous incremental evolution of the network can, when applied together with our design principles, result in a more robust network.","PeriodicalId":284960,"journal":{"name":"Proceedings of the 2016 ACM SIGCOMM Conference","volume":"416 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116559852","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}
