Among them, GEO satellites, with the benefits of large and stable coverage area, have already been used for commercial broadband communication. However, the inherent long transmission range makes the propagation delay of satellite (especially GEO) link much longer than its terrestrial counterpart. This poses challenges to TCP especially for small object transfer which takes only several RTTs. The default initial cwnd(congestion window) size of 10 has been proposed by Google[1] and enabled by Linux for many years but it is unsuitable for satellite environment. In this paper, we propose NTCP: Network assisted TCP for long delay satellite network. We introduce a ground- based SDN architecture for satellite network, propose a method to calculate the upper bound of initial cwnd based on the flow numbers and link bandwidth of each link, and scale the initial cwnd by multiplying the initial bandwidth of initial spreading[10] with link RTT. The efficacy of our scheme is proved in the evaluation part.","PeriodicalId":125877,"journal":{"name":"2016 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115142568","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}

Even weak and innocuous disturbances can bring down the system inoperative and may introduce catastrophic disasters to the society. The goal of this research is to provide effective mechanisms to enhance the resilience of large scale cyber systems. Process interactions will be modeled and the relationship between interaction and system resilience will be analyzed. The effectiveness of modularization on resilience enhancement will be illustrated. A dynamic programming algorithm based solution will be developed to provide a solution to enhance system resilience through system modularization.","PeriodicalId":125877,"journal":{"name":"2016 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115205863","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}

SDN decouples the control plane from the data plane and supports network programmability which can share network and radio resources. NFV is proposed to address the problems of network ossification and can implement network functions through pure software. In this paper, inspired by SDN and NFV, we propose a novel concept of virtual resource pipe called OpenPipe for software-defined and virtualized campus WLANs (SD-WLANs). Benefited from OpenPipe and extended OpenFlow (exOpenFlow) protocol, a relay selection method is proposed to enable relay to cover the whole area of interest and improve system network performance. In SD-WLANs, our proposed relay selection method can be easily invoked only by coding at the application layer. Experiment results demonstrate that our scheme is able to increase the total throughput, the flexibility and availability of network.","PeriodicalId":125877,"journal":{"name":"2016 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129608389","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}
