This article presents the results of deploying the application to detect and mitigate DoS attacks in various network topologies. The application installs a group of rules which control the forwarding of the data and save statistics about the network traffic regardless of the type of topology. The application estimates the throughput of different connections in the network and determines the presence of a DoS attack. Rules to drop the packets of the problematic flows are installed in case of the attack. The application has been implemented using OpenDaylight platform. The functionality of the proposed application in various network topologies has been simulated in Mininet emulator.","PeriodicalId":141827,"journal":{"name":"2021 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"317 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124496622","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}

Mushroom-shaped DRA has a peak gain of 6.5 dBi and an average gain throughout the operating band is 5.5 dBi.

Multicast and broadcast services based on Rel-17 5G NR network are supported and capable of transporting multimedia streaming or download services to various types of general-purpose 5G-capable devices. Following the principle of Release-17 5G NR MBS, China Broadcasting Network (CBN) cooperated with industry partners to develop the world's first 5G NR MBS end-to-end prototype trial system using commercially-available 5G NR network platform and 5G-capable smartphones. Based on the prototype system, field trial tests for cellular deployment and high-tower deployment are conducted for mobile and fixed receptions respectively. The field test results demonstrate the versatility, flexibility and efficiency of 5G NR multicast and broadcast technology, which can be heavily integrated with the deployed mobile communication network, and represents the evolution direction of new broadcast/multicast technology in the future.","PeriodicalId":141827,"journal":{"name":"2021 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124488610","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}
