Cloud computing enables applications to apply on-demand and scalable resources dynamically. It is necessary for Many Task Computing (MTC) to offer high performance resources in a long phase and certificate stable executions of applications even dramatic changes of vital status of physical resources. Auto-scaling on virtual machines provides integrated and efficient utilization of cloud resources. VM Auto-scaling schemes have been actively studied as effective resource management in order to utilize large-scale data center in a good shape. However, most of the existing auto-scaling methods just simply support CPU utilization and data transfer latency. It is needed to consider execution deadline or characteristics of an application. We propose an auto-scaling method, guaranteeing the execution of an application within deadline. It can handle two types of job patterns; Bag-of-Tasks jobs or workflow jobs. We simulate a variable index computation application in hybrid cloud environment. The results of the simulation show the method can dynamically allocate resources considering deadline.","PeriodicalId":269952,"journal":{"name":"The 16th Asia-Pacific Network Operations and Management Symposium","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121213452","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 average amount of spam mail reached 72.1% of all email traffic in the world in 2012. The greatest threat to the email service providers was the spam mail sent from botnet, because the spam mail sent from botnet was accounting for more than 78% in 2011; therefore appeared many anti-spam solutions and techniques that were focus on the botnet. Owing to these anti-spam techniques, botnet spam is not effective as before. Spammers are finding new way to send the spam mail. One of the effective methods is using compromised accounts (or bot accounts) to send the spam mail because compromised accounts have good reputation IP addresses and compromised accounts send the spam mail with complete SMTP implemented server, such as Gmail, Yahoo!Mail, and Microsoft Live Mail. The spam mail send form compromised accounts are very difficult to be detected by any anti-spam techniques. Hence, we focus on the features spammers cannot easily hide. According to our research we find that normal users usually do not reply to the spam mail. Moreover, our empirical analysis reveals that the compromised account actually have low reply rate. We develop a system called “Hawkeye” that can find the compromised accounts effectively by checking the account's reply rate.","PeriodicalId":269952,"journal":{"name":"The 16th Asia-Pacific Network Operations and Management Symposium","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128941153","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 general, the commercial access networks are composed of a large number heterogeneous, multi-domain, multi-technology and multi-vendor network devices. In such a network environment, the network migration is a challenging task for any service providers. The process of network migration traditionally involved a series of manual and repetitive steps. The manual process of network migration requires highly skilled staffs and is prone to human error. In this paper, we present the integrated and automated provisioning operational supporting systems (OSSs) for in-service network migration. The developed OSSs provide two kinds of in-service network migration mechanisms and support a diversity of network migration scenarios in heterogeneous networks. Finally, the results show that the proposed efficient provisioning mechanism significantly speeds up the network migration and reduces service providers' operational expenditures (OPEX).","PeriodicalId":269952,"journal":{"name":"The 16th Asia-Pacific Network Operations and Management Symposium","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134224580","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}

For this reason, many high performance TCPs have been proposed, such as Compound TCP and CUBIC TCP. Then, these proposals have caused a new issue, which is fairness among these modern TCPs. For this issue, several fairness evaluations and some proposals for improving fairness were published. However, most of these evaluations are executed using a network simulator, so fairness with actual network elements and actual TCP implementations has not been discussed enough yet. In this paper, we focus on performance fairness of modern TCPs and discuss methods for improving performance fairness with actual TCP implementations and network elements. First, we present fairness evaluation among modern TCPs and demonstrate that fairness among modern TCPs is very poor. Second, we propose methods for improving performance fairness, which drop packets of bandwidth-consuming connections in a network bridge. Third, we evaluate our proposed methods and show that our methods can improve performance fairness.","PeriodicalId":269952,"journal":{"name":"The 16th Asia-Pacific Network Operations and Management Symposium","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133954712","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}
