SDN and the Virtual Data Center
Businesses want the promise of dynamic, on-demand cloud based IT Problem: Network and VMs layers are too intertwined
• Provisioning of networks and network services cumbersome and slow• VM and network configurations must be coordinated – shared IP address domains• Changes to shared network services have unintended consequences
Solution: Fully virtualized data center (VDC)• Completely separate VM and network configuration – isolated IP address domains• Create virtual overlay networks for each virtual data center• Virtualize all network services within a VDC

VXLAN - The Benefits of Overlay Networks
Complete isolation network layer• Overlay networks are isolated from each other and
the physical network Massively extends VM cluster scale and flexibility
• Single domain for vMotion and administrative control Separation of Virtualization and Network layers
• Physical network has no knowledge of virtual networks• Virtual networks spun up automatically as needed for VDCs
Open standard• VMWare, Cisco, Citrix, RedHat, Broadcom…• IETF Draft: draft-mahalingam-dutt-dcops-vxlan-01

VXLAN Challenges – Loss of Network Visibility & Control
Total loss of visibility of overlay network – all traffic is now UDP tunneled
Virtualization layer controls all tunnel and overlay network setup/tear down
Impossible to isolate overlay traffic from physical network
Different overlay networks can have overlapping address spaces
UDP Tunnel

Customer Example – Test Systems Interact with Production
Problem Test environment was spun up to
test a new financial service Isolated from production server
with insufficient firewall rules Test system performed a series of
actual financial transactions in production environment
Fire Storm ensued to track down, isolated and undo transaction
Solution CTO top initiative = virtual data
center built upon SDN/VXLAN Network operations team is
pushing back – “We don’t have any way to manage and troubleshoot virtual/overlay networks”

Riverbed & VMware – VXLAN aware IPFIX vSphere 5.1 exports VXLAN aware IPFIX
• Provides tenant traffic information (VDC flows)• Provides tunnel traffic information (VXLAN tunnel endpoints)• Exported from VDS on ESX hypervisor
New VXLAN aware IPFIX format jointly developed • Riverbed’s expertise of performance management and NetFlow paired with
VMware’s virtual network expertise
Physical network switches and router export normal NetFlow• Visibility into physical network performance• Visibility into performance of UDP tunnels across network• Does not provide visibility into tenant traffic
