"It depends on what you're trying to do," said Shehzad Merchant, senior director of strategy at Extreme Networks. He also mentioend that Avaya, Alcatel-Lucent and Huawei have demonstrated SPB interoperability.ĭoes it scale? "This was designed to go into carriers," Unbehagen said, referring to SPB's MAC-in-MAC Provider Backbone Bridging characteristics.ĭo you other vendors on the panel plan to support it? "If you know OSPF, you know more than half of SPB," the presenter, Avaya engineer Paul Unbehagen, said. Attendees wanted to know how Ethernet and IP-like SPB was, since the presenter said "the only things that matter" when deploying SPB are IP and Ethernet. The Avaya presenter fielded most of the questions after the talks were done. It mentioned a hospital deploying SPB to support a multitenant environment.Īnother hospital running SPB to support a private cloud deployment is Advocate Health Care, which is investing $40 million in Alcatel-Lucent switches to build the Ethernet fabric. Of all the presentations, Avaya's SPB talk was the only one to provide an example of a production deployment. No one spoke specifically on behalf of TRILL, the IETF fabric specification, though Cisco did mention that FabricPath was a pre-standard version of TRILL and that Cisco switches could be configured in "TRILL mode" if FabricPath was not desired.

Some in the session remarked that MLAG is a non-interoperable standard, while QFabric and FabricPath are considered proprietary. Other panelists included Extreme Networks, Juniper and Cisco, each promoting their respective MLAG, QFabric and FabricPath implementations.

Jim Metzler's "Alternatives to Spanning Tree" panel discussion on Tuesday morning at this week's trade show generated a lot of questions for an Avaya engineer after his presentation advocating SPB as a replacement for Ethernet's Spanning Tree Protocol.
