Compared to widely adopted industrial solutions including fat-tree, this architecture can provide even higher aggregate bandwidth and richer path availability. Most importantly, FFTree provisions unique flexibility so that its topology and performance can be tailored with great freedom before its deployment. The fine granularity and wide dynamic range of its configurations allow FFTree to exactly fit and closely follow the time-variant demands of its applications. Also, this flexibility facilitates the reuse of network devices, so that upgrades could be achieved by rearranging existing switches, avoiding the expenditure on new generations of hardware in each upgrade cycle. Furthermore, this flexibility allows FFTree to be elaborately tuned into cost efficient zones in the sense that it provides higher bandwidth using less network devices, which leads to significant cost reduction. We design the network topologies of FFTree, propose a set of routing algorithms, and demonstrate its aforementioned features. We also analyze the performance and compare it with its predecessors. Technically, this architecture can be seen as a generalization of fat-tree, and is backward-compatible to fat-tree: it consists of commercial off-the-shelf network devices, and the whole system can cooperate with the hosts running Ethernet and IP. We believe FFTree is ready to be deployed in industry, as a perfect replacement of the classic fat-tree.","PeriodicalId":422861,"journal":{"name":"2017 IEEE/ACM 25th International Symposium on Quality of Service (IWQoS)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116400878","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 source of a multicast, however, does not need to be in a specific location as long as certain constraints are satisfied. This means the multicast can have uncertain sources, which could reduce the network bandwidth consumption more than a traditional multicast. Meanwhile, a reliable multicast becomes crucial in providing reliable services for many important applications. However, a prior minimal cost forest (MCF) for such a new multicast is not designed to support reliable transmissions. In this paper, we propose a novel reliable multicast routing with uncertain sources named ReMUS. To the best of our knowledge, we are the first to study the reliable multicast under uncertain sources. The goal is to minimize the sum of the transfer cost and the recovery cost, although finding such a ReMUS is very challenging. Thus, we design a source-based multicast method to solve this problem by exploiting the flexibility of uncertain sources when no recovery nodes exist in the network. Furthermore, we design a general multicast method to jointly exploit the benefits of uncertain sources and recovery nodes to minimize the total cost of ReMUS. We conduct extensive evaluations based on the real topology of Internet2. The results indicate that our methods can efficiently realize the reliable and bandwidth-efficient multicast with uncertain sources, irrespective of the settings of networks and multicasts.","PeriodicalId":422861,"journal":{"name":"2017 IEEE/ACM 25th International Symposium on Quality of Service (IWQoS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128800922","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}
