The industry at large is shifting towards SDN architectures, with white-box devices and open source software as building blocks. Such trend allows for further optimization across network layers, packet and optical as an example, with shared infrastructure and control. In this paper, we demonstrate a full end-to-end multi-stage data-center solution, combining leaf-spine control from Trellis, dedicated optical link provisioning by ODTN, and switches and packet optical programmable devices managed by Stratum.Unifying optical and Ethernet capabilities, the Cassini packet-optical transponder acts as a spine in the intra data-center Trellis leaf spine topology, and as the transponder for the DCI inter data-center links.We will describe the implemented architecture, the overall topology, the changes required to achieve the end to end solution and the challenges faced. We then outline the benefits of the proposed solution in terms of resource consumption, end to end optimisation, reliability and resiliency based upon data collected in a physical setup at ONF. Finally, we conclude this paper with future work and proposed optimisations.","PeriodicalId":163553,"journal":{"name":"2021 International Conference on Optical Network Design and Modeling (ONDM)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122011091","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}

As operators’ revenues are not scaling accordingly, several technical directions to design low-cost optical metro networks are being investigated. In this study we observe that operators can jointly i) enforce Filterless Optical Network (FON) architecture, hence removing costly Wavelength Selective Switches, ii) leverage relatively short links in metro networks to reduce the number of optical amplifiers (OAs), iii) place amplifiers intelligently to maximize signal quality (SNR), hence employing higher-order modulation formats (MF) and reducing the number of transponders. To quantify the achievable cost-reduction we develop a Quality-of-Transmission (QoT) aware planning tool, based on Genetic Algorithm, for joint optimization of fiber tree establishment (inherent to FON), OA placement and MF assignment. Results obtained over a realistic topology show that the proposed design achieves overall (4-8)% equipment cost savings compared to baseline optical network deployment, without affecting QoT.","PeriodicalId":163553,"journal":{"name":"2021 International Conference on Optical Network Design and Modeling (ONDM)","volume":"12367 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124037628","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}

We experimentally assess the performance by implementing it through a testbed including an SDN controller, Small form-factor pluggable transceiver PON (SFP+/PON), a layer 2 switch, and several SFP+ Point-to-Point (SFP+/PtP) in lieu of a traditional OLT chassis. We compared our proposition with a PtP scheme based on legacy layer 2 redundancy protocol solution with respect to different metrics such as recovery time, latency, power consumption, CAPEX and flexibility/scalability. We show that a trade-off exists among those metrics and that while the SDN-based solution is outperformed by the legacy-based one in terms of recovery time, the proposed solution still provides a remarkable improvement with respect to nowadays practices in protection, while allowing for cost and energy reduction. Such solution scheme can thus be used as a protection scheme for non-time-critical services.","PeriodicalId":163553,"journal":{"name":"2021 International Conference on Optical Network Design and Modeling (ONDM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131007839","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}

To address this growth of internet traffic, operators are searching for innovative solutions which avoid new installation and replacement of the existing network infrastructure. In this context, efficient spectrum utilization is one of the key enablers to extract the residual network capacity. This paper proposes an innovative algorithm exploiting electronic traffic grooming and using impairment-aware routing to address the virtual network embedding problem (IA-TG-VNE) in optical networks. We also analyze the networking benefits of using time-domain hybrid modulation formats (TDHMF) over four conventional modulation formats; binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), 16 quadrature amplitude modulation (QAM), and 64 QAM. The analysis is performed on a detailed physical layer model based on the Gaussian Noise (GN) model, which includes the effect of both linear and nonlinear impairments. The simulation results are obtained on realistic network topology: a 37-nodes PAN-EU. The simulation results show that TDHMF always performs better than conventional modulation formats for all types of fiber in terms of total network capacity, the average bit rate per lightpath (LP), number of LPs, and request blocking ratio.","PeriodicalId":163553,"journal":{"name":"2021 International Conference on Optical Network Design and Modeling (ONDM)","volume":"165 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131122064","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}

We evaluate the performance of two deployment scenarios for a 10-Gigabit-capable PON (XGS-PON) system using the OMNeT++ network simulator. The simulation results show that, when the delay distribution of frames is analyzed, more than 99% of fronthaul traffic at 80% load in both scenarios are below the 250 µs latency requirement.

In recent years, emerging networking languages and architectures, such as P4/PISA, have created unprecedented opportunities for rapidly prototyping disruptive solutions in programmable data planes. In this direction, source routing (SR) is a prominent alternative to conventional table-based routing, since it reduces the convergence time of building distributed routing tables. In particular, PolKA explores the polynomial residue number system (RNS) for a fully stateless SR, i.e., no state update on packet headers needs to be conveyed along the route. This paper reports the deployment of PolKA in a continental testbed composed of P4 programmable switches. Results for end-to-end throughput and forwarding latency show that PolKA matches the data plane performance of traditional approaches, while paving the way for further innovative applications by exploring RNS properties in dynamic scenarios.","PeriodicalId":163553,"journal":{"name":"2021 International Conference on Optical Network Design and Modeling (ONDM)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128789242","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}
