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

3. Locator/ID Separation Protocol
LISP creates a Level of Indirection with two namespaces: EID and RLOC
EID (Endpoint Identifier) is the IP address of a host – just as it is today
RLOC (Routing Locator) is the IP address of the LISP router for the host
EID-to-RLOC mapping is the distributed architecture that maps EIDs to RLOCs VM

4. Locator/ID Separation Protocol
Open Protocol:
RFC published
Data Plane:
Encapsulation protocol to build
a Multitenant Overlay
- MAC in IP
- IP in IP VM
App OS

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