Posts about Disaggregation

Disaggregation, open networking and SDN control have become key themes when discussing the future of optical networks at industry events. All of these interrelated topics were certainly popular at this year’s Big Communications Event in Austin, Texas, where I joined Axel Clauberg of Deutsche Telekom and Huawei’s Sean Long for a panel debate titled Optical Networks in the New Age of “Open” ...

There’s some interesting discussion in our industry on the merits of open, disaggregated/decomposed systems versus vertically integrated solutions. Some argue for a far reaching disaggregation as a means to create full flexibility, while others outline the benefit of pre-integrated sub-systems. I’d like to look at this question from a very different perspective. Evolutionary processes have proven to be very powerful at optimizing complex systems. Let’s have a look at what they can teach us ...

2015 was a big year for network functions virtualization (NFV). In recent months, the technology has made a lot of progress in its journey from the blackboard to real world implementation. We've seen NFV move from theoretical discussion to lab testing and public demonstrations. Now, as it stands ready to take its next step from demo to deployment, here's my forecast for the top five NFV trends in 2016. 1) We’ll See Major Progress in the NFV Technology Lifecycle - Leading communication service providers (CSPs) will start to make more solid commitments to NFV. Those who haven’t already done so will begin to run major projects to explore how NFV can be used to improve network efficiency by reducing hardware diversity and increasing the level of automation. Service providers with existing data centers will favor central hosting of virtualized network functions, while edge NFV will be the entry strategy for CSPs that have focused on connectivity services so far ...

Here's my Real CTO conversation with Jerome Tollet of Qosmos. Prayson: Jerome, thank you for joining me today. Qosmos has been heavily involved in NFV from almost the very beginning as one of the members of CloudNFV. Tell me a little about Qosmos’ role in the NFV transformation. Jerome: Indeed, we have been in the NFV space since the beginning. We specialize in DPI (deep packet inspection) and IP classification software. Our technology identifies application flows to prioritize traffic and analyze usage.

Just as early man realized he could smelt together copper and tin to get bronze, today’s data-driven hominid is looking at virtualization, the cloud and advanced fiber networks to imagine an entirely new datacenter. Instead of simply networking discrete facilities over long-haul trunks, why not disaggregate the various data resources, right down to the server and disk drive if necessary, and compile completely virtual data environments across large geographical areas? Not only would this enable highly specialized data architectures and infrastructure, but it would do wonders for load distribution, resource utilization and power management. Small wonder, then, that so much attention is being paid to the data center interconnect (DCI). According to Ovum, the DCI market is projected to grow from USD 2.5 billion last year to USD 4.2 billion in 2019, a 10.5 percent compound annual growth rate. Much of this activity is happening at the carrier level, but an increasing portion is coming from the Internet content provider (ICP) market, which is gaining at about 12 percent per year. The biggest limiting factor in the disaggregated DCI, of course, is latency. The farther data has to travel, the longer it takes to get there, even at light speed. The problem isn’t just ...
