In many SDN designs, the distributed controllers are acting as replicas by forming clusters. For large-scale data centers across multiple geographically distributed locations, the controllers have to maintain a synchronized global view. These restrict themselves on single point of failure, low scalability, more communication effort, bad isolation, and rigid deployment. In this paper, we propose S-Fabric, a novel data center network design, which provides a sliced control plane and a policy-based user-defined data plane. By slicing the network through flows, and assigning a non-replica controller to each slice, S-Fabric achieves flexibility and elasticity, while ensuring isolation and separation. We leverage (but not limited to) a two-tiered spine and leaf architecture, and define forwarding rules for spine, leaf and edge switch respectively. By simplifying the flow table, S-Fabric keeps the number of forwarding rules on spine switches equal to the number of used leaf/edge ports inside a data center. By matching subnets in slices to VLANs on the edge switches, S-Fabric brings backwards compatibility to traditional data centers. S-Fabric enables an incremental deployment of SDN in traditional data centers, since it requires no SDN capability on the spine/core switches."],["dc.identifier.doi","10.1145/3145777.3145790"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/57442"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.publisher","Association for Computing Machinery"],["dc.publisher.place","New York, USA"],["dc.relation.conference","ICTCE '17"],["dc.relation.eventend","2017-10-24"],["dc.relation.eventlocation","Osaka, Japan"],["dc.relation.eventstart","2017-10-22"],["dc.relation.isbn","978-1-4503-5315-1"],["dc.relation.ispartof","Proceedings of the 2017 International Conference on Telecommunications and Communication Engineering"],["dc.relation.orgunit","Gesellschaft für wissenschaftliche Datenverarbeitung"],["dc.title","S-fabric: towards scalable and incremental SDN deployment in data centers"],["dc.type","conference_paper"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
