1. Overall Description: SA5 would like to thank IETF for the LS IETF work related to the management and orchestration of network slicing. 3GPP SA5 is currently working on the Rel-15 specifications with target of completion in September 2018. As part of this normative work, 3GPP SA5 is evaluating available solutions for the coordination between 3GPP Management System and Transport Network (TN) manager for the management of 5G networks supporting network slicing feature. The following are examples of information that 3GPP management system needs to communicate to TN manager: - the topology requirement for the TN links (3GPP endpoints / nodes to be connected by the transport link, e.g. including ports information, VLAN IDs, IP addresses) - the latency requirement for the TN links - the bandwidth requirement for the TN links - the isolation requirement for the TN links The interaction 3GPP Management System communication with the TN manager have been discussed as the following: 3GPP Management System (e.g. NSMF/NSSMF) sends the TN link related requirements to corresponding TN Manager. 3GPP SA5 would like to ask IETF for information on the transport support of network slicing. 2. Actions: ACTION: To provide information on the following: 1. Which types of transport networks are in the management scope of the IETF? 2. Which interfaces would be relevant to the SA5 Management System to communicate with the TN Manager for IETF supported TN networks? 3. Can the listed transport network requirement information be supported in the RFC 8299 or draft-ietf-l2sm-l2vpn-service-model mentioned in the IETF LS? 4. Availability (time plan) of the solutions supporting the identified options from the TN management perspective that 3GPP Rel-15 management specifications can rely on. 3.
