Existing specification approaches are\r\neither ambiguous or miss important aspects regarding the behavior of virtual\r\nnetwork functions (VNFs) forming a service. We propose to formally and\r\nunambiguously specify the behavior of these functions and services using\r\nQueuing Petri Nets (QPNs). QPNs are an established method that allows to\r\nexpress queuing, synchronization, stochastically distributed processing delays,\r\nand changing traffic volume and characteristics at each VNF. With QPNs,\r\nmultiple VNFs can be connected to complete network services in any structure,\r\neven specifying bidirectional network services containing loops.\r\n  We discuss how management and orchestration systems can benefit from our\r\nclear and comprehensive specification approach, leading to better placement of\r\nVNFs and improved Quality of Service. Another benefit of formally specifying\r\nnetwork services with QPNs are diverse analysis options, which allow valuable\r\ninsights such as the distribution of end-to-end delay. We propose a tool-based\r\nworkflow that supports the specification of network services and the automatic\r\ngeneration of corresponding simulation code to enable an in-depth analysis of\r\ntheir behavior and performance."}],"file":[{"date_created":"2019-01-07T12:38:35Z","creator":"stschn","date_updated":"2019-01-07T12:38:35Z","access_level":"open_access","file_id":"6504","file_name":"ris_preprint.pdf","file_size":497528,"content_type":"application/pdf","relation":"main_file"}],"ddc":["040"],"language":[{"iso":"eng"}],"year":"2019","publisher":"IFIP","date_created":"2018-06-18T15:23:18Z","title":"Specifying and Analyzing Virtual Network Services Using Queuing Petri Nets"},{"language":[{"iso":"eng"}],"file_date_updated":"2019-04-17T12:17:42Z","ddc":["040"],"user_id":"16205","department":[{"_id":"276"}],"project":[{"_id":"1","name":"SFB 901"},{"_id":"4","name":"SFB 901 - Project Area C"},{"name":"SFB 901 - Subproject C5","_id":"17"}],"_id":"9261","file":[{"relation":"main_file","success":1,"content_type":"application/pdf","access_level":"closed","file_name":"BLED 2019 Manuscript_final.pdf","file_id":"9262","file_size":1465891,"date_created":"2019-04-17T12:17:42Z","creator":"abursig","date_updated":"2019-04-17T12:17:42Z"}],"status":"public","type":"conference","publication":"Proceedings of the 32nd Bled eConference","conference":{"name":"32nd Bled eConference","location":"Bled, Slovenia"},"title":"Jumping, dumping, and pumping: Three mental principles for idea generation to activate software-based tools in business model innovation","date_created":"2019-04-17T12:14:39Z","author":[{"last_name":"Szopinski","full_name":"Szopinski, Daniel","id":"36372","first_name":"Daniel"}],"date_updated":"2022-01-06T07:04:10Z","citation":{"ama":"Szopinski D.

While 5GPPP has identified smart manufacturing as one of the most important vertical industries, there is still a lack of specific, practical use cases. \r\n\r\nUsing the experience from a large-scale manufacturing company, Weidm{\\\"u}ller Group, we present a detailed use case that reflects the needs of real-world manufacturers. We also propose an architecture with specific network services and virtual network functions (VNFs) that realize the use case in practice. As a proof of concept, we implement the required services and deploy them on an emulation-based prototyping platform. Our experimental results indicate that a fully virtualized smart manufacturing use case is not only feasible but also reduces machine interconnection and configuration time and thus improves productivity by orders of magnitude."}],"file":[{"file_id":"9272","access_level":"open_access","file_name":"preprint_ris_with_header.pdf","file_size":374397,"creator":"stschn","date_created":"2019-04-23T09:29:49Z","date_updated":"2019-12-12T09:15:57Z","relation":"main_file","content_type":"application/pdf"}],"ddc":["000"],"keyword":["5g","vertical","smart manufacturing","nfv"],"language":[{"iso":"eng"}],"has_accepted_license":"1","place":"Valencia, Spain","citation":{"apa":"Schneider, S.

One of them is the smart man- ufacturing case which utilises 5G networks to interconnect production machines, machine parks, and factory sites to enable new possibilities in terms of flexibility, automation, and novel applications (industry 4.0). However, the availability of realistic and practical proof-of-concepts for those smart manufacturing scenarios is still limited.\r\nThis demo fills this gap by not only showing a real-world smart manufacturing application entirely implemented using NFV concepts, but also a lightweight prototyping framework that simplifies the realisation of vertical NFV proof-of-concepts. Dur- ing the demo, we show how an NFV-based smart manufacturing scenario can be specified, on-boarded, and instantiated before we demonstrate how the presented NFV services simplify machine data collection, aggregation, and analysis.","lang":"eng"}],"publication":"5th IEEE International Conference on Network Softwarization (NetSoft 2019)","title":"Prototyping and Demonstrating 5G Verticals: The Smart Manufacturing Case","date_created":"2019-04-01T13:37:05Z","year":"2019","file_date_updated":"2019-04-01T13:46:18Z","user_id":"13271","department":[{"_id":"75"}],"project":[{"_id":"28","name":"5G Development and validation platform for global industry-specific network services and Apps","grant_number":"761493"},{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C4","_id":"16"}],"_id":"8792","status":"public","type":"conference","main_file_link":[{"url":"https://doi.org/10.1109/NETSOFT.2019.8806685"}],"conference":{"location":"Paris","end_date":"2019-06-28","start_date":"2019-06-24","name":"5th IEEE International Conference on Network Softwarization (NetSoft 2019)"},"doi":"10.1109/NETSOFT.2019.8806685","author":[{"first_name":"Manuel","last_name":"Peuster","full_name":"Peuster, Manuel","id":"13271"},{"last_name":"Schneider","orcid":"0000-0001-8210-4011","id":"35343","full_name":"Schneider, Stefan Balthasar","first_name":"Stefan Balthasar"},{"first_name":"Daniel","full_name":"Behnke, Daniel","last_name":"Behnke"},{"first_name":"Marcel","full_name":"Müller, Marcel","last_name":"Müller"},{"first_name":"Patrick-Benjamin","last_name":"Bök","full_name":"Bök, Patrick-Benjamin"},{"last_name":"Karl","full_name":"Karl, Holger","id":"126","first_name":"Holger"}],"oa":"1","date_updated":"2022-01-06T07:04:01Z","citation":{"apa":"Peuster, M., Schneider, S.

They allow to dynamically steer traffic\r\nthrough the network when new network functions are instantiated, or old ones\r\nare terminated. These scenarios become in particular challenging when stateful functions are involved, necessitating state management solutions to migrate\r\nstate between the functions. The problem with existing solutions is that they typically embrace state migration and flow rerouting jointly, imposing a huge set\r\nof requirements on the on-boarded virtualized network functions (VNFs), eg,\r\nsolution-specific state management interfaces.\r\nTo change this, we introduce the seamless handover protocol (SHarP). An\r\neasy-to-use, loss-less, and order-preserving flow rerouting mechanism that is\r\nnot fixed to a single state management approach. Using SHarP, VNF vendors\r\nare empowered to implement or use the state management solution of their\r\nchoice. SHarP supports these solutions with additional information when flows\r\nare migrated. In this paper, we present SHarP's design, its open source prototype\r\nimplementation, and show how SHarP significantly reduces the buffer usage at\r\na central (SDN) controller, which is a typical bottleneck in state-of-the-art solutions. Our experiments show that SHarP uses a constant amount of controller\r\nbuffer, irrespective of the time taken to migrate the VNF state.","lang":"eng"}],"file":[{"file_size":2571927,"file_id":"8796","access_level":"open_access","file_name":"main_for_ris.pdf","date_updated":"2019-04-01T18:04:14Z","date_created":"2019-04-01T18:04:14Z","creator":"peuster","relation":"main_file","content_type":"application/pdf"}],"date_created":"2019-04-01T17:47:36Z","title":"A flow handover protocol to support state migration in softwarized networks","year":"2019"}]
