We develop a mixed integer linear program (MILP) to obtain the minimum cost shielding to guarantee the connectivity of a single SD pair under a general failure model, and exploit geometric properties to decompose the shielding problem under a geographical failure model. We extend our MILP formulation to guarantee the connectivity of the entire network, and use Benders decomposition to significantly reduce the running time by exploiting its partial separable structure. We also apply simulated annealing to solve larger network problems to obtain near-optimal solutions in much shorter time. Finally, we extend the algorithms to guarantee partial network connectivity, and observe significant reduction in shielding cost, especially when the failure region is small. For example, when the failure region radius is 60 miles, we observe as much as 75% reduction in shielding cost by relaxing the connectivity requirement to 95% on a major US infrastructure network.","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"261 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131490558","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}

We realize this dynamic DMZ model based on an OpenFlow-enabled switch and controller. In our approach, the controller detects flows with bit rate greater than a given threshold (elephant flows) and controls the switch in order to reroute elephant flows bypassing the security device. Extensive experiments are performed to verify the feasibility of this approach and test how the threshold value influences network performance. Results indicate that our approach effectively increases network performance but does not significantly influence flow security. Finally, we perform theoretical calculation on the deep packet inspection (DPI) input data rate in order to guide selection of the threshold value with a given traffic flow distribution and maximum DPI processing rate.","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"42 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133270171","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}

Provisioning redundancies, enabling failure detections and notifications, supporting a state synchronization, and invoking failure mitigation have been the essential steps to achieve the HA feature. Software-Defined Networking (SDN) is an emerging networking paradigm that centralizes the control plane by separating it from the data plane. In this paper, we identify that SDN poses more complex HA issues due to a new network domain between the control and data planes which is called the control path. It poses many critical challenges on the existing HA mechanisms to achieve the same Service Level Agreement (SLA) of HA for the services in the SDN environment. To address this problem, we propose and implement several control path HA algorithms that enhance performance as well as simplify management of control path HA.","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115438887","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}

We propose a coordinated protection plan, so called protection synergy, to protect all possible dual failures by utilizing existing single failure protection schemes. There are two aspects essential for effective dual failure protection: One is to guarantee the connectivity under any dual fiber failures, the other is to allocate minimum but enough spare capacity on both layers. Our model achieves both goals using a novel topology mapping technique and computing working and backup paths with an accurate path disjoint criterion. The experimental results on four networks demonstrate complete dual failure restorability and spare capacity savings of the protection synergy approach.","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126719312","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 has to do with the change from 16-bit to 32-bit autonomous system (AS) numbering and the employment of the fictitious AS, AS23456. This error strongly biases estimations of the number of ASes performing a type of inter-domain routing called multi-exit routing. In data from 2010, over half of apparent cases are in fact false. We show how to detect this error and obtain a truer picture of the extent of multi-exit routing.","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127024776","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}

Not only it has to minimize the load on the controller, but it must be able to react even when the controller is unreachable. In this paper we present a protection scheme based on precomputed backup paths and inspired by MPLS “crankback” routing, that guarantees instantaneous recovery times and aims at zero packet-loss after failure detection, regardless of controller reachability, even when OpenFlow's “fast-failover” feature cannot be used. The proposed mechanism is based on OpenState, an OpenFlow extension that allows a programmer to specify how forwarding rules should autonomously adapt in a stateful fashion, reducing the need to rely on remote controllers. We present the scheme as well as two different formulations for the computation of backup paths.","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124285649","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}
