SliMANO: An Expandable Framework for the Management and Orchestration of End-to-end Network Slices. In 2019 IEEE 8th International Conference on Cloud Networking (CloudNet).978-1-7281-4832-8https://hdl.handle.net/10016/31243This paper has been presented at The IEEE 8th International Conference on Cloud Networking (CloudNet)This paper proposes a slice management and orchestration framework for abstracting the instantiation of end-to-end network slices, which are composed by a chain of both physical and virtual network functions. In this line, the proposed SliMANO framework is a plug-in based system that requests network resources and coordinates the interaction among network orchestration entities for its instantiation and chaining in order to perform an end-to-end slice. These entities could range from management and orchestration (MANO), Software Defined Networking (SDN) controllers and Radio Access Network (RAN) controllers. A proof-of-concept prototype was implemented and experimentally evaluated, with results showcasing its feasibility. The results revealed a increase in the delay, associated with instantiation and deletion operations, when compared with the recently introduced network slicing feature (NetSlice) of the Open-source Management and Orchestration (OSM).6eng© 2020 IEEE.Network slicingSDNNFVMANOconference paperTelecomunicacioneshttps://doi.org/10.1109/CloudNet47604.2019.9064072open access2019 IEEE 8th International Conference on Cloud Networking (CloudNet)
