In this regards, there have been lots of efforts to develop and redesign the framework to deliver solutions that meet a variety of requirements including resilience, performance, and agility. This paper presents a design and implementation of iSDF, an integrated software-defined computing framework for scientific experiments. The iSDF aims at reinforcing traditional cloud-based scheme by supporting application-aware scheduling that avoids resource starvation and contentions for software-defined computing. To demonstrate the effectiveness of the iSDF, we evaluate it by performing several experiments based on three scenarios. The results show that our framework can achieve a 51% increase on resource utilization and average makespan time a 19% improvement compared to the conditions that do not include the policy. Thus, we proved that the framework can contribute to increase utilization for shared resources and to optimize overall makespan time, eventually affecting overall throughput of jobs.","PeriodicalId":188636,"journal":{"name":"2017 19th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115880125","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 provides Network Functions (NFs) through software virtualization techniques that decouple software and hardware. Some connected network functions constitute a service function chain (SFC). Therefore, the deployment of SFCs is much agile and simple. However, this leads to more service failure. The service failure includes service availability failure and service quality degradation. Aiming at the problem that the existing service function chain detection methods have high detection cost and cannot locate the failure accurately. This paper presents a method based on minimum detection cost. The method consists of failure detection and failure localization. In failure detection, we calculate detection paths according to the topology of network functions to avoid duplicate probing of links between network functions. In failure localization, we locate service availability failure and service quality degradation respectively and add timestamp fields to network service header to analyze locations of service quality degradation. Experiments show that the method reduces active detection cost and improves the recall and false-positive of service failure localization.","PeriodicalId":188636,"journal":{"name":"2017 19th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124467514","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}

In SDN, a switch can only work according to the rule of the flow tables received from its controller. Once the controller breaks down, the switch cannot transmit the incoming data packet which cannot be matched in the flow table. The SDN network can be severely affected by the controller failure. In this regard, we are committed to design a proper backup approach for SDN controllers to reduce the loss brought by controller failures. Besides, we attach great importance to the survivability of the control network under network failures. In this paper, we first formulate the survivability of control network. Then we propose a backup approach for controllers based on the survivability model. The network delay is considered in the backup approach. Simulation is conducted to verify the validity and efficiency of our approach. Results show our backup approach guarantees that the controller failures can be effectively recovered. Comparison results between our approach and other existing approaches prove that the approach can effectively reduce the link loss brought by network failures when the backup controller replaces the failed controller to manage the network.","PeriodicalId":188636,"journal":{"name":"2017 19th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125384929","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}

Compared with the traditional optical network, the EONs improve the spectrum utilization and increase the network capacity. So the EONs gradually become the key point of next generation optical transport networks. Obviously, the restoration mechanism in EONs has become thefocus of network operators' attention. This paper presents a dynamic restoration scheme based on software defined network (SDN) framework and an improved regional fault-tolerant routing and spectrum allocation algorithm (RSA). Using the SDN framework, we can greatly reduce recovery time and avoid configuration contentions. On this basis, we introduce the improved regional fault-tolerant RSA algorithm. The proposed RSA algorithm can decrease restoration blocking probability and relief effects caused by regional failures. The performance of the proposed dynamic restoration is evaluated in terms of restoration blocking probability and recovery time under different network loads, and compared against other schemes.","PeriodicalId":188636,"journal":{"name":"2017 19th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122103580","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}
