Requirements:− A mobility solution that:
Works across multiple access carrier networks and multiple access media (3G, 4G, WiFi)
Technology agnostic for insertion into any market (NA, SA, Asia, Eur) without customization
Simplifies end-host access and system OpEx
LISP Solution:− Provides network (access) independence
Over the top handoffs between carriers and access technologies
Mobility, IPv6/v4 independence, IP portability
− Provides unique endpoint addressing
No changes across different carriers – Endpoint IDentity never changes
Benefits:− Carrier and access technology independence
− Endpoint mobility without IP changes and Path Stretching

LISP Overview

LISP: Location-Identity Separation• LISP separates Endpoint IDentifiers (EIDs) from Routing
LOCators (RLOCs)Both EIDs and RLOCs are represented with IP addresses (in two different name spaces)
• Applications/TCP on endpoints bind to EIDsApplications/TCP are unaware of LISP
• LISP Tunnel Routersresolve EIDs onto RLOCs by querying a distributed Mapping System
Encapsulate/Decapuslate host-generated packets with RLOCs as outer addresses
Route LISP encapsulated packets to reach destination RLOC

LISP Mobility Demo
• Universal IP reachabilityLISP Mobile Node is reachable at IP address 153.16.21.34 no matter what:
Access Carrier Network (Verizon, ATT, Comcast, …)
Transport Technology (3G, WiFi, …)
• TCP Session continuity while handing off from WiFi to 3G
Webcam Server running on the LISP Mobile Node stream continuous video while switching from WiFi to 3G interface

Other Potential LISP Use Cases
• Simplified and cost-effective multihoming, redundancy and prefix portability
• Data center VM-mobility and workload distribution
• IPv6 transition incremental deployment of IPv6 using existing IPv4 infrastructure
• Highly Scalable VPN
