As for network service providers, OPCInet provides them with large switching capacity of low energy consumption, high flexibility, and efficient resource utilization in the form of a simple control mechanism. This paper presents the recent progress made in the development and deployment of an OPCInet. We have developed OPCI nodes, capable of Layer 3 switching between the Ethernet frame and the optical packet in the optical packet edge part. Burst-tolerant optical amplifier and optical buffer with optical fiber delays in 100Gbps optical packet switching part have also been developed. The header processor, capable of longest-prefix matching with very-low power consumption search engine LSIs, is also developed. Toward deployment of the OPCInet, we have succeeded in using the OPCI nodes in a lab-network that has an access to the Internet. Network management system for shifting from R&D to operation has come a step closer to reality.","PeriodicalId":410892,"journal":{"name":"2014 16th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132760346","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}

However, corporate customers have to content with a helpless bystander and victim roles due to the lack of tools to detect and counter-act Internet-scale traffic redirection. An world-wide redirection of target traffic will compromise unencrypted communications and allow the deployment of various attacks on encrypted communications. This paper proposes a world-wide distributed probing methodology to detect traffic routing variations. Upon detection, a corporate customer cannot act in terms of Internet-scale routing but can warn its network service providers and request consequent actions. Nevertheless, upon warning, the corporate customer can locally deploy extreme security policies, like terminating sensible deferrable communications (database/information synchronization, audio/video calls) and increasing the required encryption level for public services. The proposed solution is easily deployed and has a very low implementation cost. The proof-of-concept presented in this paper uses worldwide deployed probes to detected specific traffic redirection. The results obtained reveal that the proposed methodology, due to this world-wide spreading of the probes and joint analysis of measurements, is able: (i) to detect Internet-scale traffic redirection attacks, and (ii) ignore localized licit inner-AS rerouting.","PeriodicalId":410892,"journal":{"name":"2014 16th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132154050","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}

Daily and weekly traffic fluctuations as well as yearly traffic growth are considered when analyzing the power consumption. Low power mode in optoelectronic devices (sleep-mode and rate adaptive capabilities) is implemented within a traffic-aware networking approach. The impact of dedicated 1:1 protection in a dynamic network scenario is considered and a comparison is made with the unprotected case. A GMPLS control plane is implemented and used to re-configure the power-adaptive devices and connections. Results show that symbol-rate adaptation provides high savings for unprotected scenarios (37% energy savings w.r.t. unprotected Baseline), while for the protected scenarios better results are obtained for modulation format adaptation which includes sleep-mode (57.1% energy savings w.r.t. protected Baseline). Moreover, compared to the Baseline scenarios the Mixed adaptation, combining both symbol-rate and modulation format, is the most power-efficient strategy providing 39% energy savings for unprotected scenario and 70% energy savings for dedicated protection scenario.","PeriodicalId":410892,"journal":{"name":"2014 16th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114867192","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}

Traditionally, either active or passive measurements are considered. While active measurements allow to know exactly the workload injected by the application into the network, the passive measurements can offer a more detailed view of transport and network layer impacts. In this paper, we present a hybrid approach in which active throughput measurements are regularly run while a passive measurement tool monitors the generated packets. This allows us to correlate the application layer measurements obtained by the active tool with the more detailed view offered by the passive monitor. The proposed methodology has been implemented following the mPlane reference architecture, tools have been installed in the Fastweb network, and we collect measurements for more than three months. We report then a subset of results that show the benefits obtained when correlating active and passive measurements. Among results, we pinpoint cases of congestion, of ADSL misconfiguration, and of modem issues that impair throughput obtained by the users.","PeriodicalId":410892,"journal":{"name":"2014 16th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129725543","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}
