To provide a smooth and cost-efficient network evolution, inverse-multiplexing techniques can be employed to carry the high-capacity data streams. In this context, the Virtual Concatenation (VCAT) protocol, available in Optical Transport Network (OTN) systems, represents the most adequate solution to decompose the 100-GbE signal into logical containers of 10 Gb/s and 40 Gb/s. With VCAT, each container can be independently routed throughout the network under several distribution paradigms, such as the classical single-path and multipath schemes, and the alternative degraded-service approach. In the network architecture considered, each routing path is required to be transmitted over an optical channel at the underlying WDM layer. Hence, in this work, we provide an optimization framework for solving the resource provisioning problem for 100-GbE at both OTN and WDM layers. Linear Programming based heuristics are proposed for routing the containers and dimension the capacity required at the OTN level. In particular, solutions for single-path, multipath, and degraded-service routing are described and evaluated in a reference network topology. The optimization procedures are also extended to resolve the wavelength assignment problem at the physical WDM layer. With this optimized multilayer architecture, the capacity gains resulting from the adoption of multipath strategies over single-path are properly evaluated and demonstrated. In addition, it is shown that the implications of using diverse-routing over the WDM layer have a minor impact in the capacity savings.","PeriodicalId":162766,"journal":{"name":"2009 Next Generation Internet Networks","volume":"362 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129158113","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, the session-based QoS control defined in NGN standardizations is not designed for layer 2 infrastructures, but for border gateway function (BGF) at IP edge. To achieve QoS assurance for NGN services, end-to-end network resource management, including layer 2 access and metro networks, is required. Although the BGF function needs to be introduced at IP edge, legacy infrastructures must be utilized especially for access and metro networks. Incorporating those widely deployed legacy infrastructures into session-based QoS control mechanisms is expected. However, differences in user-flow identification of NGN and resource identification required for managing legacy infrastructures induce gaps blocking integration to the unified session-based infrastructure. This paper proposes to use a network middleware for bridging NGN control frameworks and legacy infrastructures. With the multiple service oriented architecture (SOA) chain, the network middleware distributedly coordinates middleware element managing each network segments, and harmonizes differences of resource description and control procedures in NGN and legacy infrastructures. The network middleware enables to maintain coherent QoS policy for the end-to-end route of the session-based services throughout the heterogeneous and multi-layer infrastructures.","PeriodicalId":162766,"journal":{"name":"2009 Next Generation Internet Networks","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123957931","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}

Our proposal is based on the observation that many trips of the mobile users are daily trajectories according to certain routines, for instance from home to the working place and vice-versa. Also we assume that the network can predict the mobile's position at the cell level. Based on those aspects, our scheme works as follows. If the mobile terminal visits an expected cell, a target cell, before a certain movement threshold M is reached, its movement counter is reset to zero. If the movement counter of the mobile terminal reaches the threshold M before visiting the target cell the mobile terminal will trigger a location update message. \u0000 \u0000With this strategy, since mobile terminals have less contacts with the network, the uncertainty on their location increases and as a consequence of that, in order to keep the terminal paging cost below reasonable bounds, a selective polling strategy based on the expected trajectory of the mobile terminal should be applied. To that purpose a selective line-paging-Iike procedure is considered. Two step and three step paging procedures have been implemented. The net effect is a significant saving in the total signalling load (location update + paging) supported in the air interface. The assertion of this expected result has been carried out using a suitable Markovian analytical framework.","PeriodicalId":162766,"journal":{"name":"2009 Next Generation Internet Networks","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129518653","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 this paper, we address Quality of Service (QoS) and fairness issues in a novel OPS ring architecture with a slotted synchronous transmission mode. The basic MAC protocol in the studied architecture is similar to the CSMA/CA mechanism. Using this mechanism, each node in the network may use the available bandwidth in an opportunist manner. Moreover, in the considered network, optical packets bypass intermediate nodes without being delayed or converted to the electronic domain. Therefore, the chances for a ring node to find available transmission resources are tightly correlated to the matrix of traffic of the other nodes. This leads to unfair sharing of the transmission medium. In order to remedy this problem, we elaborate a distributed Tag-based Enhanced Access Mechanism (TEAM). The proposed solution evolves from two preemptive access mechanisms that we have proposed recently (namely the Packet Erasing Mechanism PEM and the Extraction and Reemission Mechanism ERM). In order to resolve the unfairness issue, which characterizes ring OPS architectures with transparent transit at intermediate nodes, we use an advanced distributed approach where all ring nodes cooperate together. Finally, we evaluate the performance of the TEAM mechanism through several simulation scenarios.","PeriodicalId":162766,"journal":{"name":"2009 Next Generation Internet Networks","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128014602","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}
