Project Fi intelligently connects mobile users to free open WiFi hotspots or otherwise, if not possible, seamlessly moves them between the two partner LTE networks for delivering the most reliable and fastest available wireless service. Project Fi may be an important step towards meeting the 5G requirements of ultra-high reliability and very low latency while taking economic considerations into account. Following the integrative vision of 5G, this paper attempts to provide further insights into the potential of Project Fi wireless service by elaborating on the integration of 4G LTE-Advanced (LTE-A) heterogeneous networks (HetNets) and low-cost data-centric Ethernet based fiber-wireless (FiWi) broadband access networks with not only WiFi offloading but also cost-saving fiber infrastructure sharing capabilities for small cell backhaul, which is becoming a major performance-limiting factor in mobile networks. Furthermore, given that decentralization is another important aspect of the 5G vision, we develop a decentralized routing algorithm for the resultant FiWi enhanced LTE-A HetNets.","PeriodicalId":360703,"journal":{"name":"2015 IEEE 16th International Conference on High Performance Switching and Routing (HPSR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130605039","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}

This paper considers the optimal DCN placement for DCN failure risk minimization against such region failures. We first apply a general probabilistic region failure model to determine the failure probability of a node/link, and then propose a general grid partition-based scheme to flexibly define the global distribution of a region failure in terms of its occurring probability and intensity. Such grid partition scheme also helps us to evaluate the vulnerability under a region failure. With the help of the vulnerability information, we further propose an Integer Linear Program-based theoretical framework to identify the optimal DCN placement to lead to the minimum DCN failure risk under a region failure. An example and extensive numerical results are also provided to illustrate the proposed framework for DCN placement.","PeriodicalId":360703,"journal":{"name":"2015 IEEE 16th International Conference on High Performance Switching and Routing (HPSR)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124102187","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}

Thus, to offer true ubiquitous Internet connection, a Fixed and Mobile Converged (FMC) network architecture is essential for the future 5G network. Such a convergent network can not only improve the utilization of network resources, but also inspire new add-on services for FMC network operators. In this paper, we introduce a shared caching overlay based on Information Centric Networking (ICN). It is deployed on top of the FMC network and controlled by the FMC network operator to offer Caching as a Service (CaaS) to Over-The-Top (OTT) service providers and virtual network operators. Business analysis and performance evaluation will highlight the benefits of deploying such a controlled Shared Caching System (SCS) over an FMC network.","PeriodicalId":360703,"journal":{"name":"2015 IEEE 16th International Conference on High Performance Switching and Routing (HPSR)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124515937","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}

Elastic optical switches are used as nodes in elastic optical networks (EONs), where fine granular frequency slots or flexible grids are used in opposite to the traditional optical networks, where fixed grids are used. The switch architecture considered in this paper consists of waveband converting switches in input and output stages, while in the center stage there is only one wavelength selective space switch without wavelength conversion capabilities. We derive the number of frequency channels k needed in interstage links to ensure the nonblocking operation of the switch when input and output links have n frequency channels and a frequency slot of one connection is not greater than m frequency channels. Both, necessity and sufficient conditions are proved.","PeriodicalId":360703,"journal":{"name":"2015 IEEE 16th International Conference on High Performance Switching and Routing (HPSR)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116808955","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 perfect match: Optical Bypass and SDN partitioning 完美匹配:光Bypass和SDN分区

{"title":"The perfect match: Optical Bypass and SDN partitioning","authors":"M. Caria, A. Jukan","doi":"10.1109/HPSR.2015.7483112","DOIUrl":"https://doi.org/10.1109/HPSR.2015.7483112","url":null,"abstract":"A lot of research, development, and standardization efforts are going on to extend the latest buzz in packet networks called Software-Defined Networking (SDN) to the optical domain. We argue though that a reasonable combination of packet layer SDN with dynamic optical transport (in whatever flavor) is already possible with some architectural adaptations. We therefore propose to combine a recently proposed networking scheme called SDN Partitioning with dynamic optical circuits used in the form of Optical Bypasses. The method uses a few SDN nodes in a hybrid SDN/OSPF network, such that they partition the OSPF domain into sub-domains, thereby already achieving traffic engineering capabilities comparable to full SDN operation only by manipulating OSPF routing protocol updates when they cross sub-domain borders. The method provides that local routing inside sub-domains remains stable at all times, while inter-sub-domain routes can be optimized. The Optical Bypasses among border nodes come into play to dynamically offload transit traffic from frequently traversed (transit) sub-domains to the optical layer in case of increased traffic demands. Our simulation results show that the combination of a few SDN nodes with a few Optical Bypasses allows to cope with traffic surges up to a degree that renders excessive over-provisioning of link capacities or full SDN migration completely unnecessary.","PeriodicalId":360703,"journal":{"name":"2015 IEEE 16th International Conference on High Performance Switching and Routing (HPSR)","volume":"4 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114005226","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 new generations of these highly flexible FPGA architectures can be reconfigured on-the-fly, allow parallell processing of data arriving at high-speed, and even contain hundreds of DSPs (Digital Signal Processors), to further parallelize certain, computationally intensive tasks. This paper demonstrates some of the capabilities of a new, FPGA-based networking platform, C-GEP. This multi-purpose, programmable platform can support various tasks, from being a high-speed switch/router, through pre-processing packets for Deep Packet Inspection, towards being the Forwarding Plane element in the SDN infrastructure. The current demonstration contains two further implementations of 100 Gbit/s-capable applications: a traffic generator - firing off multi-encapsulated packets - and a lossless traffic monitor - that is able to classify and steer the monitored traffic to further post-processors.","PeriodicalId":360703,"journal":{"name":"2015 IEEE 16th International Conference on High Performance Switching and Routing (HPSR)","volume":"33 Suppl 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132835016","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}
