SNAC •  First roll out with OpenFlow 0.8.9 •  Nicira + SNAC used as example controllers •  HP 5412 switches – early firmware releases •  Stable but proved less than ideal update mechanism •  Floor-based VLANs used to isolate tests •  OpenFlow 1.0 offered opportunity to examine newer

solutions

Problem #1: Wireless Mesh •  Wireless mesh networks becoming common •  Hosts can have multiple valid attachment points to

an OF network •  OF controller had to be enhanced to deal with not

just host mobility, but multiple valid paths

Page 35: OpenFlow/SDN:ANew Approach)to)Networking)cenic2012.cenic.org/program/slides/CenicOpenFlow-3-9-12-submit.pdfBroadcom,)Brocade)Ciena,)Cisco,)Citrix,)Dell,)Ericsson,)Extreme,) ... •

Problem #2: Controller Plane Loop

•  New packet-in results in a flowmod that is pushed from the controller to the switches

•  Under heavy loads, one vendor's switch was too slow with flowmod insertions and routed output packet as another packet-in - Loop

•  Lesson: Switch does not guarantee order of processing flowmod and packet-out

Page 36: OpenFlow/SDN:ANew Approach)to)Networking)cenic2012.cenic.org/program/slides/CenicOpenFlow-3-9-12-submit.pdfBroadcom,)Brocade)Ciena,)Cisco,)Citrix,)Dell,)Ericsson,)Extreme,) ... •

Problem #3: Unidirectional OF Link

•  LLDP Packets in a VLAN not always recognized by some non-OF switches and were forwarded

•  Unexpected switch behavior resulted in unidirectional OF links in the topology that controller could not yet handle: Net outage

•  Lesson: Must handle unidirectional links between OF switches as different OF clusters

Problem #4: DHCP Relays

•  Controller's attempt to understand relay-agents and forward packets to the correct end host

•  Stanford and other networks tend to have multiple DHCP servers that are load balanced by the relays

•  Optimization was premature, and its best to maintain local relay-agents

Final Takeaways

•  OpenFlow/SDN shows a lot of promise as a new paradigm for networking

•  Network operators embracing it for their own reasons –  Enable innovation and offer customized services –  Reduce CapEx and OpEx

•  Vendors are stepping up to meet customer demands •  Universities have an opportunity to lead

–  Deploy OpenFlow/SDN infrastructure; innovate services; reduce CapEx and OpEx

–  NSF willing to support the upgrade –  Vendors willing to cooperate and help
