Distributed Data Centers
Many physical sites - One logical Data
Center
Layer 2 Ethernet Extension
Ethernet LAN Extension over any Network
• Ethernet in IP “MAC routing”
• Multi -datacenter scalability
Simplified Configuration & Operation
• Seamless overlay - No network re-design
• Single touch site configuration
• Provisioning Automation
High Resiliency
• Failure domain isolation
• Seamless Multi-homing
Maximizes available bandwidth
• Automated multi-pathing
• Optimal multicast replication
Any Workload, Anytime, Anywhere
Unleashing the full potential of compute virtualization

Access Pod 2
• Clusters, VMotion require L2 extensions to go across access pods
• Improves Manageability
• Dynamic Annexation
• Portability & Expansion

Ease of Provisioning - Problem Primary data center maxed out (space, cooling and power)
- Requirement Seamlessly extend clusters and workload across data centers
- Challenge Rapidly establish DCI between data centers
• No new transport provisioning required (Dark fiber, MPLS, etc) • Eliminate months of re-design effort • Significant operations and provisioning cost savings (no new protocols )
Solution: OTV – Establish DCI in 5 minutes!
Deploy over existing Network
4 configuration commands per site
No Re-design Required
Ethernet Overlay
One Logical Data Center
Automatic Fault Isolation

OTV at a Technical Glance
Ethernet traffic between sites is encapsulated in IP: “MAC in IP”
Dynamic encapsulation based on MAC routing table
No Pseudo-Wire or Tunnel state maintained
Communication between MAC1 (site 1) and MAC2 (site 2)

LISP: Location Identity Separation Protocol
Internet
Device IPv4 or IPv6 address
represents identity and
location
Today’s Internet Behavior Loc/ID “overloaded” semantic
x.y.z.1 When the device moves, it gets a new IPv4
or IPv6 address for its new identity and
location
w.z.y.9
Device IPv4 or IPv6
address represents
identity only.
When the device moves, keeps its IPv4 or
IPv6 address.
It has the same identity
LISP Behavior Loc/ID “split”
Internet
a.b.c.1
e.f.g.7
Only the location changes
x.y.z.1
x.y.z.1
Its location is here!
