While the Management Plane driven MAC (MP-MAC) protocol is based on an quasi-static configuration derived from optimization model, the Control Plane driven MAC (CP-MAC) protocol is based on adapting Passive Optical Network (PON) upstream traffic control, originally designed to access network, to the metropolitan network. The performance levels delivered by both approaches are compared by simulating a TWIN network applied to a Multi-hEad sub-wavElength swiTching (MEET) architecture that ensures an all optical aggregation between the regional metropolitan and the core networks. The simulation assesses the QoS delivered to three different classes of service, for a packet level traffic trace obtained from an operational network.","PeriodicalId":162507,"journal":{"name":"2015 20th European Conference on Networks and Optical Communications - (NOC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128424205","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, two SR implementations are presented and successfully demonstrated in two different network testbeds. The first implementation focuses on a software defined networking (SDN) scenario where nodes consist of OpenFlow switches and the SR Controller is a specifically designed enhanced version of an OpenFlow Controller. The second implementation includes a novel Path Computation Element (PCE) scenario where nodes consist of commercially available IP/MPLS routers and the SR Controller is a new extended version of a PCE solution. Both implementations have been successfully applied to demonstrate dynamic traffic rerouting. In particular, by enforcing different segment list configurations at the ingress node, rerouting is effectively achieved with no packet loss and without requiring the use of signaling protocols.","PeriodicalId":162507,"journal":{"name":"2015 20th European Conference on Networks and Optical Communications - (NOC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130612962","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 model the ISI effect due to delay spread in the UV channel and evaluate the approach of direct sequence spread spectrum (DSSS) in eliminating ISI and improve the system performance. Both the measured noise and newly reported experimental results of impulse response are introduced and incorporated. Numerical simulations are conducted to analyze the relations between bit-error-rate (BER) and spread factor, sample number, data rate. The results indicate that the DSSS reduces the ISI effect evidently.","PeriodicalId":162507,"journal":{"name":"2015 20th European Conference on Networks and Optical Communications - (NOC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123998500","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}

An excessive power feed voltage will cause damage to the cable and joints and so the system should be designed to maximize the power available per repeater using the available voltage. Furthermore, the optical system design must use the available power efficiently in order to maximise the system capacity. Here, both electrical and optical design methodologies are considered which achieve this aim. It is found that the ideal span loss is in the range 8-10dB and that the system should be operated in the linear regime of the fibre, obviating the need for high effective area fibres. Furthermore it is shown that higher order modulation formats are inefficient in ULH systems as sufficient bandwidth is available and standard PM-QPSK allows for greater capacities. In this respect, spectral efficiency is a poor metric to assess such systems. Through optimization, it is shown that transpacific systems of up to 250 Tb/s over 10 SDM channels are feasible using amplifier bandwidths of 70nm.","PeriodicalId":162507,"journal":{"name":"2015 20th European Conference on Networks and Optical Communications - (NOC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133116458","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}

Less is known about the CO2 released into the atmosphere during the embodiment of the devices and their lifecycle emissions. The aim of this paper present results of lifecycle modelling work carried in the EU 7th Framework Programme `BATS' project (Broadband Access via integrated Terrestrial and Satellite systems).
