Elephant traffic flows can be routed over provisioned and dedicated lightpaths (optical flows) while other (mice) flows, which are routed by electronic switches, are unaffected. In some solutions, Wavelength-Selective Switches (WSSs) are employed in the optical nodes to individually route the lightpath towards its destination. WSSs take time to be switched and delay the lightpath setup time. In this paper, the authors compare three service policies for WSS devices aiming to reduce the lightpath setup and tear down times. The conventional service policy assumes that each setup (tear down) request is handled individually. Two other service policies assume that groups of setup (tear down) requests are handled together by the WSS. These policies are implemented in a discrete event simulator, which is used to estimate the end-to-end lightpath setup and tear down time across an arbitrary mesh network. Simulation results show that group service policies outperform the conventional policy at high loads. The grouping policies are useful to reduce the lightpath setup time especially in the presence of lightpaths that are frequently set up and have relatively short holding time (short duration of elephant-optical flows).","PeriodicalId":169489,"journal":{"name":"2017 IEEE 18th International Conference on High Performance Switching and Routing (HPSR)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114065041","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}

Since a Bloom filter can produce false positives, the positive results of a Bloom filter should be identified whether the positives are true or not by accessing the original database. A complement Bloom filter (C-BF) was introduced to identify the true positiveness of a given Bloom filter without accessing the original database. A critical problem of the C-BF is that every element included in the complement set of the given set should be programmed into the C-BF. Since the number of elements included in the complement set can be considerably large, the C-BF would require the significant amount of memory. In this paper, we claim that the elements that produce negative results from the given Bloom filter are not necessarily programmed into the C-BF, since Bloom filters never produce false negatives. In other words, we propose the Petit-BF (P-BF) which programs only the elements that cause false positives from the given Bloom filter. Simulation results and theoretical analysis show that the proposed method can achieve the same performance using a considerably smaller amount of memory.","PeriodicalId":169489,"journal":{"name":"2017 IEEE 18th International Conference on High Performance Switching and Routing (HPSR)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114941653","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}

Among these characteristics, it is possible to highlight the ability to transmit data with different bandwidths, adapted to the demand, which guarantees a high spectral efficiency. Different techniques and heuristics have been presented in order to solve the Routing and Spectrum Allocation (RSA) problem, which emphasize in providing efficient solutions for the packaging of requests within the optical spectrum. In this article, it is proposed the adaptation of an efficient spectrum assignment heuristic, referred to as Min Slot-Continuity Capacity Loss (MSCL), with the Split Spectrum technique. It is shown that by combining different forms of spectrum division with the spectrum assignment that generates the least loss of capacity, an efficient technique may be applied to EONs that provides better results than either the traditional algorithms of spectrum allocation (FF and MSCL) and the classic form of spectrum division.","PeriodicalId":169489,"journal":{"name":"2017 IEEE 18th International Conference on High Performance Switching and Routing (HPSR)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123681949","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 objective of this paper is to increase such guaranteed OSNR, which in turn enables bandwidth-efficient modulation formats to be applied to the circuit signals. The guaranteed OSNR is improved by applying OSNR-driven Spectrum Assignment (OSA) constraints to each fiber link in the network, based on its forecast traffic volume (offered load). Applying OSA constraints to fiber links has two conflicting outcomes. On the one hand, circuit requests may experience higher blocking probabilities due to the lack of usable spectrum. On the other hand, the adverse effects of medium nonlinearity may be contained, thus yielding improved circuit OSNR. Two OSA constraints are described and their favorable impact on circuit OSNR (up to 2.75 dB gain) is estimated by using a Gaussian Noise (GN) model and an event-driven simulation of two WDM networks supporting dynamic circuits.","PeriodicalId":169489,"journal":{"name":"2017 IEEE 18th International Conference on High Performance Switching and Routing (HPSR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123713172","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}
