Our proposal involves cooperation between the routing and the wavelength assignment tasks. The main idea is to classify each wavelength at an output link of a node as suited either to sending or to relaying data bursts. Furthermore, burst retransmission management is important to realize OBS networks. We propose the cooperation method considering retransmission. Simulation results show that the proposed method can reduce the burst loss probability, particularly for long-distance transmissions. As a result, unfairness in the treatment of short and long hop bursts can be alleviated.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"7 1","pages":"410-425"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.7.000410","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66588838","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}

Design of survivable grooming capable networks is of critical importance. For such networks, protection may take place at the lightpath level or at the connection level. However, optimal formulations for implementing protection at either level are computationally intractable and can only be used for very small networks. We present an efficient integer linear program (ILP) formulation for the complete survivable traffic grooming problem, including topology design, traffic routing, and routing and wavelength assignment, using both dedicated and shared protection at the lightpath level. Unlike existing formulations, our ILP is able to generate optimal solutions for practical sized networks with hundreds of traffic requests.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"7 1","pages":"378-387"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.7.000378","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66588265","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 the core part we investigated the role of the classes of services defined according to the differentiated service over MPLS and to the virtual private LAN service approach. Furthermore we also investigated the role of the restoration consequent to a link failure. For the access part we will show that for the asymmetric digital subscriber line 2+ (ADSL2+) architecture an important role is given to the edge routers to select the traffic with higher priority. Furthermore we show how an upgrade of the passive optical networks, by means of the WDM technique, can be particularly suitable for future peer-to-peer huge bandwidth services.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"7 1","pages":"426-435"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.7.000426","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66588897","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 network performance is evaluated using computer simulations at both physical and logical layers, taking into account the service and protection operational states. The study developed in the optical layer assesses the impact of several physical impairments in the upstream and downstream transmission, while the logical analysis evaluates the performance of different dynamic bandwidth allocation algorithms operating in the medium access control layer of the upstream channel.

It is apparent that as higher-speed services, such as IPTV, become available there will be even greater demand for capacity in the distribution and core transport networks. Hence, it is no wonder that underlying optical transport infrastructures need to be scalable and robust to reliably and economically support these services. Service providers have long recognized the importance of transmission capacity in the design of their networks. However, technological limitations often obscure the role of transparency in meeting their requirements. We review and clarify the critical role that optical transparency will have in facilitating the types of optical infrastructures required to support future services and highlight the technologies that enable it. In particular, we summarize recent advances in broadband Raman amplification, transmitter and receiver technologies with advanced modulation formats, dispersion management, signal processing, reconfigurable optical add-drop multiplexing, and dense wavelength-division-multiplexed transmission with mixed 10, 40, and potential 100Gbits/s channels.
