2 Abstract The goal of this presentation is to contribute contents of section 12 in the architecture recommendation document. Agenda Single layer networks Multi-layer technology with multiplexing Recursive NS agents
3 Section 12 in recommendation document Sections 12 Examples and use cases 12.1 GMPLS intradomain with NS agents 12.2 Single layer networks 12.3 Multi-layer technology networks 12.4 Multi-layer technology with multiplexing 12.5 Recursive NS agents Contents Overview of a use case application Target network layer Sequence to use NSI by the application Functional / Non-functional requirements of the application
5 Single layer networks Application: Data transfer Overview: To transfer data under stable network, a network path between a client and server is provisioned. The network path may be coallocated with computing resources. Layer: L1 or L2 e.g. eVLBIe.g. Visualization Dynamically provisioningStatically provisioning
6 Single layer networks UA#1App NSA#1 Find a data server where required data is stored Call NSI Request data request data download Call NSI Release Established
8 Multi-layer technology with multiplexing Application: VoIP Overview: To ensure end-to-end bandwidth and jitter, a telecom carrier will provide a guaranteed network path. In general, a telecom carriers network consists of access / metro network (layer 2 network) and core network (layer 3 network). Moreover, in the metro / core network, traffic of users will be aggregated into a network path. Layer: L2 & L3 (multiplexed) This use case was presented at NSI-WG in OGF24.
