Also, many applications have changed their traffic pattern frequently due to various reasons. Nevertheless, network managers tend to stay with old signatures. But they should update with new signatures to detect the modified application traffic. The extraction of signature is work to demand a lot of time. And it is difficult to continuously and timely extract the new signature for all applications. In this paper, we propose a noble signature management system which automatically extract new signatures detecting the modified traffic and delete old signatures no longer used. The proposed system analyzes traffic with existing signatures and extracts new signature automatically for updated traffic. For automatic generation of new signatures, we uses a sequence pattern algorithm. Also, the proposed system analyze usage of the old signatures to remove them when they are not used any more. We proved the feasibility and applicability of the proposed system by showing that that detection rate of all application was increased.","PeriodicalId":269263,"journal":{"name":"2015 17th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115991278","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 becomes a new challenge for many carriers to deploy a variety of new services by effective provisioning of network resources. Software-Defined Networking (SDN) is a novel approach to make networks reconfigurable and extensible such that new services can be deployed with existing network devices. By decoupling the controller plane from the data plane in network devices, SDN brings networks programmability of the data plane and centralization of the controller plane. Conventional Operations Support Systems (OSSs) were developed to manage networks in a standard fashion with Simple Network Management Protocol (SNMP) or proprietary protocols. SDN provides a new framework in managing SDN-enabled devices. A new issue for carriers is how SDN-enabled networks and devices can be monitored and controlled by current OSSs. This paper focuses on performance management and aims to develop an efficient scheme to collect traffic statistics data via the SDN controller plane. Similar to Bulkstat, an SNMP-based mechanism for periodic collection and transfer of MIB objects, the proposed scheme for bulk traffic statistics collection is developed in the controller plane and provides a northbound interface for upper network management applications. Instead of using SNMP and MIBs, the scheme is implemented by periodically gathering statistics information of flow tables from SDN-enabled switches via the OpenFlow protocol.","PeriodicalId":269263,"journal":{"name":"2015 17th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129752802","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}

Many detection approaches relying on specific rules or inference models have been proposed to distinguish faulty sensors by exploring spatial-temporal correlations among sensor readings. However, these approaches may require high communication overhead or computational cost, and many potential faulty sensors that may not generate anomalous sensor readings remain undetected. In this paper, we propose a metric-correlation-based distributed fault detection (MCDFD) approach. It is motivated by the fact that the correlations between sensor nodes' system metrics usually perform regularly, whereas abnormity of such correlations indicates failures. MCDFD explores sensor nodes' internal metric correlations using correlation value matrixes. An improved cumulative summation (CUSUM) algorithm is used to track gradual changes or abrupt changes. Once any changes occur in correlation value time sequences, potential failures can be detected. The apply of metric correlations has made MCDFD with high-energy efficiency and low computational complexity, since no communication overhead is incurred and CUSUM algorithm is simple for computation. Simulation results demonstrate MCDFD performs well in respects of higher detection accuracy and lower false positive rate even under high node failure ratios and dense distribution conditions.","PeriodicalId":269263,"journal":{"name":"2015 17th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130652153","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}

ITS provides immediate traffic information for vehicles location tracking, vehicle dispatching, also can be used on taxi management and police cars, fire trucks, ambulance dispatching when serious accidents occur. On quality assurance, ITS involves many kinds of Information and Communication Technology (ICT) devices and services. Different services and devices have their own Operation Support System (OSS) and it is hard to exchange information. Therefore, our research proposes a framework to integrate end-to-end quality assurance information based on Digital Service Reference Architecture (DSRA) supported by TM Forum. Our framework manages all sub-systems of ITS such as Mobile virtual private network(VPN), fixed-line VPN, ITS car devices, dispatching service platform, etc. It made root cause analysis consuming time less than 10 minutem. and can improve time to market and quality assurance for ICT composite digital service.","PeriodicalId":269263,"journal":{"name":"2015 17th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"34 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128750029","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}
