3 What this talk is about. Internet Architecture Software Defined Networks.. and its companion Network Function Virtualisation Data Centres Networking (kind of...) 3

4 Internet Architecture Once upon a time there was the IP hourglass. 4

5 Splitting the IP Address Semantic Identifier Space ASj Locator Space Internet (DFZ) ASw RLOC 1 EID s RLOC 2 EID d ASs ASz ASk ASd RLOC 2 EID s RLOC 1 EID d EIDs ITR/ETR Ingress/Egress Tunnel Routers (xtrs) EIDd 5

6 Life of a Packet in a LISP World.. Bindings between ID and Locators: Mappings AS j Internet AS w RLOC 2 EIDx RLOC 1 EIDy AS z AS k ASx ASy RLOC 1 EIDx RLOC 2 EIDy EIDx RLOC 2 EIDx EIDx RLOC 2 EIDy EIDy EIDy EIDx EIDy RLOC 1 EIDx RLOC 1 EIDy RLOC 2 EIDx RLOC 2 EIDy 6

7 LISP main benefits FIB (Forwarding Information Base) shrunk since stub AS do not inject anything in the DFZ (Default Free Zone)* PI Addresses Just a matter of changing RLOCs Multi-Homing Just a list of RLOCs Traffic Engineering Just a matter of giving priorities to RLOCs Churn Flapping Edge AS are not anymore in the DFZ Additional Benefits Path Diversity * There is a deployment issue: early adopters benefit 7

8 But there is more LISP Cloud Networking VPN Content Distribution intra-dc TE Inter-DC TE VM Mobility/Migration Real-Time Traffic Optimization A different kind of SDN... and to chain services/functions (Advertisement) The Future Looks LISP.. 8

9 VM Mobility in DCs Commercial Data Center Fabrics use BGP host routing including local routing detection and adjustments Redistribute BGP => LISP Host Route Advertisement Map-Notify Map-Server (Private) Map-Register Redistribute BGP => LISP Host Route Advertisement BGP Domain BGP Domain BGP Router xtr BGP Domain BGP handles move Detection, Notification, Routing BGP Domain 9

10 LISP for Inter-DC Traffic Engineering Prefix DC2: {RTR1, RLOC1} <Priority 1; Weight 50%> {RTR2, RLOC2} <Priority 1; Weight 50%> RLOC3 <Priority 2; Weight 100%> RTR1 RTR2 RLOC1 RLOC2 RLOC3 DC 1 DC 2 RTR - Re-encasulating Tunnel Router xtr 10

11 Real-Time Traffic Engineering ALTO: Path Selection Service Allows evaluating paths from both network and business perspectives LISP: Inter-domain Tunneling Service Allows easy and lightweight traffic differentiation LISP + IDIPS: Flexible inter-domain TE 11

12 Will we finally be always connected?? ASX ASWiFi ASY ASG Internet AS4G Where to you put support in the Network? Mobile IP?... so ask Apple, Google, WiFi ISPs, and 4G ISP to deploy it Besides we still lack implementations 12

13 Wait why the heck am I using only on NIC at a time??? ASX ASWiFi ASY ASG Internet AS4G Often called Offloading What to offload? When to offload? How to offload? 13

14 My Mobility provider ASX ASWiFi ASY ASG Internet AS4G Mobile Service Provider: Third part connection manager on the smartphone Proxy in the network Think about local caches (Google, Akamai,.) Tunnel in between 14

15 What I need??? Flow-Optimizer Applications LISPmob.org Android* implementation of LISP (Cisco -UPC) Dynamic IP (Locator) assigned by your 4G Service Provider Smart TE Manager LISP Applications use the EID only (Loopback Interface) Traffic goes through LISP LISP tunnels through appropriate interface 4G if WiFi if Loopback Dynamic IP (Locator) assigned by your WiFi Service Provider Static IP (EID) assigned by your MO Service Provider 15

16 LISP Activities LISP mobility and large scale deployment evaluation Yue Li (Phd) ANR LISP-Lab Project Mobility SMR vs Versioning Large Scale Deployments Atlas measurement campaign LISP Metrology Yue Li (PhD) Abo Seif Akram (Intership) Inspired from LISP Mobile nodes (offloading) TBD 16
