Recently, at the Interop conference in New York, there were few topics about OpenFlow, especially compared to the Interop conference in Las Vegas in May focusing on software-defined networks.
The "absence" of OpenFlow may mean that the Protocol is not as ready as some people think. The OpenFlow protocol is expected to allow engineers to extract or detach the control plane of the network, so as to centrally manage the data streams in many vswitches and routers and automatically provide dynamic network resources in the cloud.
At the Interop exhibition in Las Vegas, 15 vendors participated in the Interop OpenFlow experiment and presented the demo version of the test product. NEC's OpenFlow switch won the Best of Interop Award, and Extreme Networks released a network architecture based on OpenFLow. It thinks and HP says there are custom requirements. In addition, HP promises to give OpenFlow more research and development resources.
But at the Interop conference in New York this week, the data center switch released by HP was not associated with OpenFlow. Moreover, companies like NEC, Extreme, and BigSwitch have promised to use Openflow in Interop in Las Vegas.
What happened?
Brad Casemore, a blogger at sugon network in Silicon Valley, wants to know whether there are significant differences in demand between companies, service providers, and giants like Google and Facebook. Enterprises say they still need traditional multi-functional switches and routers, which can be forwarded based on the data in the MAC address table. However, enterprises that support the cloud environment are willing to make some attempts for flexibility.
Some vendors may also realize that they are giving up too early. In his blog, the IOS Hints blogger Ivan Pepelnjak wrote, "is the Openflow network empty talk? The most difficult part of OpenFlow is writing Controller Software. Everyone is keen on it, but it is not easy ."
Of course, the "absence" of OpenFlow may also be attributed to the cruel economic form. After all, if you do not sell products, do you still have money to attend the trade fair? Tom McCafferty, director of Vyatta, reminded us that there was an OpenFlow forum in California in October 25. "Maybe they are saving their budget ." He said.
