1 LISP for SDN and NFV Vina Ermagan, Cisco Systems Sharon Barkai, ConteXtream Feb 4 th 2014

2 Agenda LISP Overview LISP and SDN Availability in open source LISP in OpenDaylight Demos: Service Chaining and Disaster Recovery LISP and NFV

3 Locator/ID Separation Protocol LISP creates a Level of Indirection with two namespaces: EID and RLOC EID (Endpoint Iden-fier) is the IP address of a host just as it is today RLOC (Rou-ng Locator) is the IP address of the LISP router for the host App OS Lisp Mapping Database EID- to- RLOC mapping is the distributed architecture that maps EIDs to RLOCs RLOC Space Site B Internet Site C Site A EID Space EID Space

4 Locator/ID Separation Protocol Open Protocol: RFC published Data Plane: EncapsulaMon protocol to build a MulMtenant Overlay - MAC in IP - IP in IP App OS Lisp Mapping Database Control Plane: Mapping of Overlay address Space to underlying physical Network including policy roumng Site B Internet Site C Any Physical Network: LAN,WAN,Hybrid Site A

5 Locator/ID Separation Protocol - policies Open Protocol: RFC published Data Plane: MulMtenant Overlay Control Plane: Mapping (+ policy) of overlay to underlying network App OS App OS Lisp Mapping Database Policy: - MulMhoming - Load Balancing - Disaster Recovery Site B Internet Site C Site A

6 Locator/ID Separation Protocol - policies Open Protocol: RFC published Data Plane: MulMtenant Overlay Control Plane: Mapping ( + policy) of overlay to underlying network App OS Database Policy: - Traffic Engineering - Service Chaining

7 SDN and LISP The consensus on SDN Decoupling of Network Control Plane form the Data Plane Programmable Open The goals of SDN Increase flexibility and development speed of features and funcmonalimes LISP as we just saw Enables network virtualizamon via dynamic mulmtenant overlays Decoupled control plane and data plane Programmable mapping system Open

27 LISP and NFV

28 Network Func5ons Before NFV Coupled with roumng topology, capacity, availability, and roumng hardware appliances AHer NFV Decoupled from roumng, cloud capacity, elasmcity, availability, standard servers capacity

29 Programmable Network Before NFV Programmable Overlay Coupled with roumng interfaces, VLANs, LSPs, VRFs AHer NFV Programmable Overlay Decoupled from Underlay, map & encap methodology

30 LISP Ideal for SDN-NFV SDN NVO LISP " Map & Encap uses IP for both transport & database NFV " 5- tuple flows: as the basis for mapping lookup- cache " Publish- Subscribe: for mapped lookups, change- SMR " ApplicaMon specific LISP XTRs: Flow handlers and ALGs " Mapping Affinity: of subscriber to funcmon available globally " Mapping Balancing: between funcmon VIP EID to instances EID " Mapping Chaining: of subscribers EID to service EID to RLOCS " Mapping as the basis for NFV orchestramon integramon Neutron+
