Various channel borrowing schemes have been proposed in the literature with their performance, typically in terms of blocking probability, obtained by computer simulations. However, analytical approximation methods are much more computationally effective and practically useful for performance analysis of mobile cellular networks. In this paper, we model mobile cellular networks with channel borrowing as overflow loss systems. We present two methods for approximation of blocking probabilities in such systems, one based on the classical Erlang fixed point approximation (EFPA) approach, and the other derived from the recently established information exchange surrogate approximation (IESA) framework. Comprehensive results of both EFPA and IESA are provided and compared against simulation results. We demonstrate for a wide range of scenarios that IESA is more accurate in evaluating blocking probabilities than EFPA. To the best of our knowledge, our proposed approximation framework is the first workable approach in terms of accuracy and computational efficiency for cellular networks with consideration to mobility of calls and a channel borrowing mechanism.","PeriodicalId":360703,"journal":{"name":"2015 IEEE 16th International Conference on High Performance Switching and Routing (HPSR)","volume":"40 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":"123366498","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}

Large-scale disasters may cause huge data loss and connectivity disruption in these networks. As our dependence on network services increases, the need for novel survivability methods to mitigate the effects of disasters on communication networks becomes a major concern. Software-Defined Networking (SDN), by centralizing control logic and separating it from physical equipment, facilitates network programmability and opens up new ways to design disaster-resilient networks. On the other hand, to fully exploit the potential of SDN, along with data-plane survivability, we also need to design the control plane to be resilient enough to survive network failures caused by disasters. Several distributed SDN controller architectures have been proposed to mitigate the risks of overload and failure, but they are optimized for limited faults without addressing the extent of large-scale disaster failures. For disaster resiliency of the control plane, we propose to design it as a virtual network, which can be solved using Virtual Network Mapping techniques. We select appropriate mapping of the controllers over the physical network such that the connectivity among the controllers (controller-to-controller) and between the switches to the controllers (switch-to-controllers) is not compromised by physical infrastructure failures caused by disasters. We formally model this disaster-aware control-plane design and mapping problem, and demonstrate a significant reduction in the disruption of controller-to-controller and switch-to-controller communication channels using our approach.","PeriodicalId":360703,"journal":{"name":"2015 IEEE 16th International Conference on High Performance Switching and Routing (HPSR)","volume":"25 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":"129510382","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}

It is a great challenge to create such a platform - especially with reconfigurable hardware and line-rate capabilities reaching and exceeding 100 Gbit/s. These requirements together put FPGA (Field Programmable Gate Array) technology into the focus of high performance networking. In this paper, we introduce a highly flexible, programmable, multi-purpose networking platform, which is capable of hosting multiple 1 and 10 Gbit/s Ethernet interfaces - beside their 40 or 100 Gbit/s interface. The hardware of the introduced C-GEP platform is reconfigurable, even on-the-fly; due to the FPGA technology. C-GEP can host a wide range of high-speed network specific applications - including monitoring, switching and media conversion -, and it is aligned with the SDN principles. The system consists of two main building blocks: a high performance FPGA-based custom specific hardware platform and the firmware tailored to the actual task. The architecture is briefly introduced by its hardware and firmware setup, then some of the core functionalities, such as packet processing, filtering, and switching are presented.","PeriodicalId":360703,"journal":{"name":"2015 IEEE 16th International Conference on High Performance Switching and Routing (HPSR)","volume":"109 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":"129656287","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}
