Lisp Service Provider NFV Use Case Draft Sharon Barkai lispwg IETF91 1 Background • Lisp architecture intro has progressed to last call, It's now possible to evolve its applicability to service provider uses cases • There are two main types of service provider use cases that need Lisp network virtualization, consumer services and business services • Both engage virtualized network functions (NFV) in provider-edge points of presence and datacenters, lisp optimizes NFV FlowMapping 2 Lisp based FlowMapping for Scaling NFVs 3 Lisp based FlowMapping for Scaling NFVs 4 Lisp based FlowMapping for Scaling NFVs in ODL 5 Orchestration and Management Network Functions SDN-XTR Federated Control Distributed Mapping Overlay Tunnel Ov e rla Underlay yT un ne l SDN-XTR rla e Ov Legend: ContexNode Mapping SFF Switch Controller Network Functions Tunnel Switch 6 nn u yT el Network Functions SDN-XTR SDN-XTR SDN-XTR Overlay Tunnel Ov e rla Underlay yT un ne l SDN-XTR ContexNode Tunnel Switch Mapping SFF Switch Controller BYO-CE Legend: 7 e Ov rla nn u yT el vCE BYO-CE Orchestration and Management Without LISP - virtualization hot potato: NVE - NVE - SFF1 - NVE - NVE - SFF2 - NVE - NVE - SLB - NVE - NVE Logical Chain2 Logical Chain1 7.2 8.1. 7.1... 8.2 Inet Carrier Spine2 1.1.1.x Carrier Spine1 1.1.2.x NVE 7.2... 8.1. 1.1.1.2 7.1.. 8.1.
