Posts about Internet Content Providers

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” ...

If there's one thing that can be said about the emerging distributed data environment, it's that it will be chaotic. At the moment, most long-haul connections between data centers and remote sites are built for largely predictable workloads: a daily data dump or at least semi-regular file transfers of reasonable size. As the enterprise gravitates toward multi-cloud infrastructure, however, the wide area network will take on more of the characteristics of the local area network: rapid, dynamic interchanges of data and applications that can wreak havoc on capacity planning, bandwidth management and other functions. Part of the solution to this problem is the data center interconnect (DCI), which provides broadband connectivity over great distances, usually on optical transport. But simply building a wider pipe is not enough. In order to gain optimal efficiency, the DCI will also have to scale dynamically to suit this constantly shifting mix of traffic ...

2015 was a seminal year for data center interconnect (DCI) technology. It was the year that ever increasing spending by big data center operators and Internet content providers finally made the communications industry take note. No longer second fiddle to large Tier 1 Service Providers, large data centers were finally heard when they said “we need something different”. And the optical communications industry responded in a big way, not just tweaking existing products, but launching entirely new product lines to serve their big needs (and big spend). But if DCI hype reigned supreme for 2015, what does 2016 have in store for us all? Well, with the disclaimer that one predicts the future at his own peril, there are 5 major trends that I think show signs of being huge for DCI in 2016: 1. Power Efficiency Will Continue to Dominate - Power efficiency has always been important to DCI and it will stay on the agenda in 2016. Data center operators have plenty of money and space, just not power. They are literally building underfilled warehouses in the hopes that future power efficiency gains will allow them to fill them to capacity ...

In the last few years, Data Center Operators and Internet Content Providers (ICPs) have grown from being just footnotes on analysts' charts to dominating transport bandwidth consumption. A pervasive question in the press this year has been how much bandwidth do the new kings of consumption really need? One prognosticator will claim they need as much as they can get, and would buy a Petabit if made available today, while another industry sage proffers a single Terabit will suffice for the foreseeable future. So who's right? It turns out, both. To illustrate the point, let's look at two ICPs in the exact same line of business, similar in size, global reach, and number of subscribers. Both have hundreds of thousands of servers running in leaf and spine configurations. Computing clusters are formed by groupings of these servers and switches between them. These clusters used to be ...
