4 NFVi Sicing (NECOS project) A Sice is an aggregated set of resources that can be used in the context of an end-to-end networked service comprised of virtua network functions. Sices are composed of mutipe resources which are isoated from other sices and aows ogicay isoated network partitions, with a sice being considered as the basic unit of programmabiity using network, computation and storage. If we have sicing everywhere, incuding networks and DCs, we observe the foowing attributes: there is a separation of physica/ogica resources there is isoation of services as no customers share physica/ogica resources it is secure as ony specified customer can access host, no sharing or cross VM issues

5 NFVi Sicing (NECOS Project) For this sice approach, we have designed and buit a DC Sice Controer which is abe to aocate a sice of a DC and create an an on-demand per-sice. The DC sice and the are provisioned soey for use with the service. Each sice and its associated are independent of the other sices and s. Each of these sices wi be aocated and de-aocated in an on-demand fashion. A customer interacts with a Sice Controer, and requests a new sice. The resuting sice wi be isoated from the other sices. In this instance, the SONATA Orchestrator is the customer. The foowing side presents how the resources of a DC are isoated from each other, and how a Sice Controer is invoved in such a process.

8 Muti-MANO interworking Concept Two (or more) Service Patforms (SPs) cooperate for rapid and dynamic service provisioning in an NFV MANO environment. Motivation A SP/orchestrator can everage on a segment of NFVi or on other SP to instantiate functions, services and network sices The operator has segmented its infrastructure in order to meet the demands of separate organisation/departments. It depoys a hierarchy of service patforms that need to coaborate in order to depoy NFV end-to-end services and/or network sices across the network.

13 SONATA-to-SONATA Summary One SONATA patform utiizes another SONATA patform to orchestrate a subsection of the NFVI. Supports either compete outsourcing of a network service for depoyment in a ower SP or spit service depoyment across two SONATA SPs. Extended SONATA Infrastructure Abstraction faciitates the communication between the higher eve SP and the ower eve one /vims and /wims API used by higher eve SP in order to gather information on avaiabe NFVI-PoPs, avaiabe resources and WAN connectivity in the NFVI orchestrated by ower eve SP

14 Muti-MANO interworking: 5GEX to SONATA MANOs / SPs might be of different impementation or technoogy to meet varying objectives. In this scenario, we ook at higher eve MANOs / orchestrators everaging ower eve MANOs to orchestrate virtua resources on the far segment of the NFVi. Impementation a 5GEx MANO interaction with mutipe SONATA SP instances dynamic software controed NFVi Sicing + on-demand

15 5GEx-SONATA interaction scenario A remote orchestrator (5GEx MANO) at higher eve over a ightweight domain (UCL VLSP impementation) and two SONATA SP instances A REST interface between 5GEx domain adapters and each SONATA Gatekeeper Each SONATA SP operates on top of a sice/partition of the NFVI, using a VLSP An Upgraded Infrastructure Adapter drives creation of sices by interacting with the Sice Manager Each End-to-end service composed of mutipe VNFs, on-boarded as services in each SONATA Service Patform and exposed as Domain Capabiities to the 5GEx orchestrator.

18 Concuding Remarks This work marks the 1 st demonstrated interaction between two MANO Patforms showing how one can map different service and infrastructure modes, reying on MANO's fexibe architecture and rich APIs This work aso shows how MANO has been adapted to a siceabe NFV Infrastructure. A fu sicing mechanism with Sice Controer, and a new and WIM wrapper for VLSP have been deveoped This work highights the importance of muti-mano operation, which is an emerging and essentia part of Muti-Domain Management MANO recursivity promises great vaue for Teecom industry who wants to manage their distributed depoyments, in an NFV environment.

20 Demo Fow - Overview 1. Different service eements are aready on-boarded by department/businessunit deveoper on each SONATA SP 2. VLSP and SONATA domain adaptors in the 5GEx MANO are turned on. 3. SONATA Domain Orchestrators gather information on topoogy and capabiities and pass it back to the domain adaptors 4. Each SONATA SP interacts with the Sice Controer of the PoP that creates a new sice and configure a at runtime for the service 5. The end-to-end service instantiation and operation via the higher eve MANO
