We investigate the impact of taking the embodied energy of network devices into account in the physical topology optimization and compare it to optimizing the physical topology considering operational energy only. The results show significant embodied energy savings up to 59%, resulting in a total energy saving of 47%. We also investigate energy-efficient data compression for optical networks and how to achieve a trade-off between the power consumption of computational resources and memory required to compress and decompress data and the network power savings. The results show that optimizing the data compression ratios in IP over WDM networks considering the non-bypass approach has saved up to 55% of the network's power consumption. Furthermore, we evaluate the power consumption of BitTorrent, the most popular P2P content distribution protocol, over IP over WDM networks and compare it to client/server (C/S) systems. The results reveal that the power-minimized BitTorrent converges to locality in order to achieve lower power consumption, resulting in 36% power savings compared to the C/S model.","PeriodicalId":151401,"journal":{"name":"2012 16th International Conference on Optical Network Design and Modelling (ONDM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122320072","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}

Given the high bandwidth required by these applications, Wavelength Division Multiplexing (WDM) networks are seen as the natural choice for their transport technology. Among the various on-line strategies proposed to provision such services, the ones based on service level agreement (SLA) metrics such as setup delay tolerance and connection holding-time awareness showed a good potential in improving the overall network blocking performance. However, in a scenario where connection requests are grouped in different service classes, the provisioning success rate might be unbalanced towards those connection requests with less stringent requirements, i.e., not all the connection requests are treated in a fair way. This paper addresses the problem of how to guarantee the signal quality and the fair provisioning of different service classes, where each class corresponds to a specified target of quality of transmission (QoT). With this objective in mind three fair scheduling algorithms are proposed in a dynamic traffic scenario, each one combining in a different way the concept of both set-up delay tolerance and connection holding-time awareness. Proposed solutions are specifically taylored to facilitate the provisioning of the most stringent service class so as to balance the success rate among the different classes. Simulation results confirm that the proposed approaches are able to guarantee a fair treatment reaching up to 99% in terms of Jain's fairness index, considering the per-class success ratio, without compromising the improvements in terms of overall network blocking probability.","PeriodicalId":151401,"journal":{"name":"2012 16th International Conference on Optical Network Design and Modelling (ONDM)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114515145","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}

These formats impose far greater demands on networks for high-capacity, low latency and stringent Quality-of-Service (QoS) compared to other existing formats. In addition, their data-intensiveness will require real-time interconnection of multiple, possibly distributed, high performance media processing and storage resources. To cater to this, novel networked architectures are required. In this paper, we propose a cloud-based architecture for the deployment of FMNs over intelligent optical networks. The key requirements of FMNs are identified and we discuss the features of our proposed architecture which meet these requirements. We formulate Integer Linear Programs (ILP) which model Non-adaptive and Adaptive Media- and Network-aware schedulers for the implementation of media streaming applications over our architecture. These models aim to maximize the number of jobs provisioned while ensuring the serving network is never overloaded. Results obtained from evaluations show the adaptive service implementation outperforms its non-adaptive counterpart in terms of number of jobs provisioned and overall Quality-of-Experience (QoE) offered by the infrastructure.","PeriodicalId":151401,"journal":{"name":"2012 16th International Conference on Optical Network Design and Modelling (ONDM)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125995317","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 is based on the principle of inverse-multiplexing which distributes high speed data stream into multiple low rate optical paths. The main challenge in parallel transmission is the differential delay experienced by different paths. Thus so far, electronic buffering has been widely used to compensate for differential delay. However, at very high speed line rates, such as 40Gbps or even 100Gbps, electronic buffering maybe a challenge. In this paper, we study the usage of Fiber Delay Lines (FDLs) for compensation of differential delay in optical parallel transmission in support of high speed Ethernet services. To this end, we formulate the problem of optimal usage of FDLs in optical networks an Integer Linear Programming (ILP) problem. The results are encouraging as they show that discrete nature of delay provided by FDL buffers is not as limiting as expected, and that FDLs carry potential to enable optical parallel transmission without the need to provide large electronic buffers.","PeriodicalId":151401,"journal":{"name":"2012 16th International Conference on Optical Network Design and Modelling (ONDM)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131774909","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}

Recently, the requirement of effective traffic engineering solutions has lead to the standardization of the PCE architecture, thus joining the distributed GMPLS control plane with a centralized network element devoted to path computation. However, the common need of network carriers to keep the network under a centralized control in strict relationship with the NMS has prevented the wide deployment of GMPLS in currently working optical networks. OpenFlow proposal has been recently designed for controlling Ethernet-based access/metro networks. However, thanks to its potential ability of configuring the flow table of generic switching nodes, the OpenFlow extension for enabling the control of WSONs is currently a hot research topic. In this work, OpenFlow is seen as a promising alternative for controlling WSONs. In particular, two OpenFlow-based solutions are considered and compared against GMPLS. The first solution comprises direct configuration of the optical nodes and extends OpenFlow protocol to improve the lightpath reservation. The second solution integrates OpenFlow with GMPLS protocols exploiting communication between the OpenFlow controller and the GMPLS controller of optical nodes. Simulations results show the ability of the OpenFlow-based solutions to enable traffic engineering while providing fast lightpath setup and assuring control plane scalability.","PeriodicalId":151401,"journal":{"name":"2012 16th International Conference on Optical Network Design and Modelling (ONDM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124397830","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}
