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.

For extended flexibility, we go beyond seeing services as a fixed chain of functions. We define the service structure in a flexible way that enables changing the order of functions in case the functionality of the service is not influenced by this, and propose a YANG data model for expressing this flexibility. Flexible structures allow the network orchestration system to choose the optimal composition of service components that for example gives the best results for placement of services in the network. When number of flexible services and number of components in each service increase, combinatorial explosion limits the practical use of this flexibility. In this paper, we describe a selection heuristic that gives a Pareto set of the possible compositions of a service as well as possible combinations of different services, with respect to different optimization objectives. Moreover, we present a heuristic algorithm for placement of a combination of services, which aims at placing service components along shortest paths that have enough capacity for accommodating the services. By applying these solutions, we show that allowing flexibility in the service structure is feasible.","lang":"eng"}],"doi":"10.1002/nem.1963","author":[{"first_name":"Sevil","last_name":"Dräxler","full_name":"Dräxler, Sevil","id":"31764"},{"id":"126","full_name":"Karl, Holger","last_name":"Karl","first_name":"Holger"}],"year":"2017","title":"Specification, Composition, and Placement of Network Services with Flexible Structures","date_updated":"2022-01-06T07:02:42Z"},{"abstract":[{"text":"In conventional large-scale networks, creation and management of network services are costly and complex tasks that often consume a lot of resources, including time and manpower.

To experience the full potential of these approaches, innovative development support tools and service provisioning environments are needed. To answer these needs, we introduce the architecture of the open-source SONATA system, a service programming, orchestration, and management framework. We present a development toolchain for virtualized network services, fully integrated with a service platform and orchestration system.

For extended flexibility, we go beyond seeing services as a fixed chain of functions. We present a YANG model for describing the service structure in deployment requests in a flexible way that enables changing the order of functions in case the order of traversing them does not affect the functionality of the service. Upon receiving such requests, the network orchestration system can choose the optimal composition of service components that gives the best results for placement of services in the network. This introduces new complexities to the placement problem by greatly increasing the number of possible ways a service can be composed. In this paper, we describe a heuristic solution that selects a Pareto set of the possible compositions of a service as well as possible combinations of different services, with respect to different resource requirements of the services. Our evaluations show that the selected combinations consist of representative samples of possible structures and requirements and therefore, can result in optimal or close-to-optimal placement results.","lang":"eng"}],"main_file_link":[{"url":"http://ieeexplore.ieee.org/search/searchresult.jsp?newsearch=true&queryText=10.1109%2FNETSOFT.2016.7502412"}],"doi":"10.1109/NETSOFT.2016.7502412","author":[{"id":"31764","last_name":"Dräxler","first_name":"Sevil","full_name":"Dräxler, Sevil"},{"first_name":"Holger","last_name":"Karl","full_name":"Karl, Holger","id":"126"}],"title":"Placement of Services with Flexible Structures Specified by a YANG Data Model","year":"2016","date_updated":"2022-01-06T06:52:53Z","oa":"1","citation":{"chicago":"Dräxler, Sevil, and Holger Karl. “Placement of Services with Flexible Structures Specified by a YANG Data Model.” In <i>Proceedings of the 2nd International IEEE Conference on Network Softwarization (NetSoft)</i>, 184--192, 2016. <a href=\"https://doi.org/10.1109/NETSOFT.2016.7502412\">https://doi.org/10.1109/NETSOFT.2016.7502412</a>.","short":"S.
