- 6. Why should you care? If any of these are important to you: • Datacenter Virtualization, multi-tenancy, recovery from failures, traffic engineering and load-balancing • WAN/Backbone Resiliency, reliability, determinism, traffic engineering and load-balancing • Campus Network access control, guest access, BYOD, hospitality networks • Security Firewalls, intrusion detection and prevention, blacklists, enforced quarantine Tallac Networks Confidential
- 7. Why should I care? If you have a datacenter • The bulk of the research being done, and of the investment being made around SDN technology, is happening in the datacenter space. • Why so much interest around SDN in the datacenter? o Specific agility needs o Specific resiliency needs o Specific traffic engineering needs vSwitch o Specific multi-tenancy needs Server Tallac Networks Confidential
- 8. Why should you care? If you have a WAN Case Study: Google has already implemented SDN for their WANs Data Forwarding Data o COTS silicon Forwarding o Openflow 1.0 o Failover and traffic shaping Data Data Forwarding Forwarding o So successful they are moving datacenter networking to SDN Data Data Forwarding Forwarding Tallac Networks Confidential
- 9. Why should you care? If your do router configuration • Labor-intensive CLI or GUI • Maintaining consistency among routers • Quickly adapting to changes Data Forwarding Data and/or failures Forwarding Data Forwarding Data • Forwarding Many of the same patterns and issues as the datacenter Data Forwarding Tallac Networks Confidential
- 10. Why should you care? If you do load-balancing • Load-balancing well-suited for SDN o Flow-based simple routing decisions Load Balancer o SDN is designed to adapt quickly to changes • Challenges for SDN o Stateful flow needs o Deep packet inspection needs Tallac Networks Confidential
- 11. Why should you care? If you use firewalls • Simple firewalls straightforward to implement o Block/allow IP addresses Firewall o Block/allow TCP/UDP ports • Challenges for SDN Firewall o More complex firewall rules o Deep packet inspection needs Tallac Networks Confidential
