Software Defined Networking and 100G are hot topics at symposium
Last week, I presented some of my work at the annual North America Technology Symposium sponsored by Adva Optical Networks, at the Millenium Broadway Hotel in New York City. Regular readers of my blog will recall that Adva is among the many companies who have publicly endorsed the Open Datacenter Interoperable Network (ODIN), which is IBM’s vision for next generation data networking. While the Adva symposium was admittedly focused mostly on their solutions, there were many interesting presentations of general interest. The presentations are available here, but Id like to review the highlights in this blog.
The symposium was a full day event, opening at 9 AM with a welcome from Adva’s CEO, Brian Protiva, followed by a series of invited speakers. After lunch, two breakout sessions were offered for either enterprise or carrier networking (I chose the enterprise track, which focused on 100G metro and 16G Fibre Channel SAN). The day wound up with a Q&A session and dinner.
First, one of the Vice-Presidents from Verizon discussed adoption of software defined networking to create what he called “service aware networks”. He cited several examples of how carriers and ISPs can leverage SDN to grow top line revenue and provide value added services. We heard many interesting factoids during the day, such as how Internet content consumptions, driven by video, will grow 10X by 2017. It was clear that commoditized hardware and centralized software control were creating an interesting value proposition in this market.
Later, my presentation dealt with using SDN to help manage the combination of exponential capacity growth and declining margins faced by many ISPs and cloud providers. In the past, networking was all about how quickly you could deploy, scale, and manage infrastructure to create value. Networking equipment was relatively feature-poor; a combination of low bandwidth, customer ASICs with low functionality and immature protocols in the data and control planes made it difficult to realize a higher value proposer. That’s all changing; modern Ethernet bandwidth is approaching that of a computer back plane, flatter 2 tier Clos or mesh topologies offer better performance, and protocols like TRILL and OpenFlow coax more value from merchant silicon. In this age of network affluence, users demand a higher quality of service, including bandwidth and latency guarantees, turnkey provisioning, and application aware network optimization. This leads to a new value proposition form SDN networks; virtualization of the data center network and beyond is the next big frontier. This value doesn’t’ come with out challenges though. Current OpenFlow is driving us back to a centralized management framework, and scaling is an issue. The benefits of a flow switched topology are clear, however, and include standardized, fine grain flow control, rapid application deployment, and end-to-end performance guarantees – real value that clients are willing to pay for.
From Michael Haley, IBM Distinguished Engineer, we learned more about how cloud computing is changing the world. Market dynamics are volatile; look t the world’s 10 largest companies from the year 2000,k and you’ll only recognize 2 of the same names on the list today. But the market potential is also growing; there will be over a trillion devices connected to the Internet next year. And smart enterprise CEOs are leveraging hybrid cloud in 60% of their installations (up from 33% just tow years ago). Cloud adoption is driven by workloads, and some analysts believe that a major section will be compute as a service, representing over 20% of a projected $55B market in 2014. Business analytics, social business, telecommunications, banking, mobile video, healthcare, and utilities dominate in different markets worldwide. In China, for example, strategic investments in “cloud cities” have been launched to support a major part of their current $4 Trillion, 5 year economic plan.
Supporting an earlier assertion about bandwidth growth, the enterprise breakout sessions included a live demonstration of 100G metro Ethernet and a discussion of the power, space, and cost for such solutions. Using a network test set and traffic source, Adva showed how they can transport 100G over metro distances with appliances about 1 U high that fir into a standard 19 inch equipment rack. Various cable configurations and latency measurements were also made during this presentation.
I’m sure by now you’ve got the general idea…Bandwidth is exploding in the metro area at lower cost than ever before, driven by new applications such as cloud computing and the promise of software-defined networking. Put on your shades, the future for metro optics looks bright indeed.
Are you looking forward to high bandwidth optical links in the metro cloud, or are you just blinded by the light? Drop me aline or send me a tweet @Dr_Casimer if you’d like to discuss more.
