Cyberattacks: Lower Bandwidth Growth Rates?

January, 2015

Going back to 9/11, there began the realization that an attack on data center infrastructure would make a large corporation the most vulnerable – even more than the loss of the leadership. Simply put, it could stop business in the water. It seems that one of the biggest areas of potential exposure to cyberattacks is in the handoff to outside networks, and if there is a substantial shift in enterprises minimizing these interfaces, it would obviously decrease the amount of bandwidth needed for transport by public networks. We know of one Fortune 250 corporation, which has had at least two encounters with cyber hackers in China over the last two years regarding stolen intellectual property. One of the attacks involved Windows 2000 (Microsoft retired and stopped supporting those servers), and so the engineering team moved horizontally across the company to take control of those...

New Title II Will Choke Optical Investment

February, 2015

The logical presumption associated with the madness of the FCC’s planned takeover of the Internet will be that service providers should be expected to cut back on fiber optic network investment to an absolute minimum, at least until litigation in the courts has been completed. It is also reasonable to conclude that the impact on purchasing of equipment by these carriers of net traffic will be even worse than what happened with the Telecommunications Act of 1996 in which the incumbent carriers were forced to unbundle their infrastructure. The expected Title II ruling is more detrimental because it is a demonstration of a federal agency, reflecting the overall plan of the current administration, which is behaving as if it has virtually boundless legal authority over Internet service providers. Up until fairly recently, there was bipartisan support in the US for a more or less...

Monetizing Older Networks: An Overreach?

March, 2015

Although one of the most thought-provoking panels at OFC 2015 will be on the monetization of optical networks, which will include seasoned experts who are vigorously involved in building new revenue models, it is not easy to imagine the kind of cultural metamorphosis that would be required for incumbent service providers to change their long-standing, bureaucratic behavior. In addition, while it is only commonsense to switch from a model that requires a lengthy period of time to install a circuit with a long-term commitment to more of a cloud-driven, network-on-demand paradigm, in which files can be loaded for say, a couple hours to be analyzed, we have discussed the very legitimate structural...

Optical Line Interoperability Illusion

October, 2015

Although Microsoft and others have been discussing the notion of an Open Line System (OLS) to provide standardization with long-haul and metro equipment, there is little precedent for such grand notions ever coming close to being real with any technologies in the past. Naturally, large service providers are always inclined to ask for everything under the sun, including compatibility between vendors to potentially reduce their operational costs. (In responding to an RFI or RFP from the three largest incumbent carriers in the US, if a supplier does not at least say it has a plan to accommodate absolutely every request, it will immediately be eliminated from consideration.). However, despite countless successful interoperability tests that have been performed over the years, optical vendors, especially the biggest ones, at the end of the day, usually have absolutely no desire to enable...

SDN Crack-Up?

February, 2016

About a half of a decade after the announcement of the establishment of the Open Networking Foundation, a recent survey of over 3,000 customers internationally by F5 Networks, indicated that just 3 percent of respondents are utilizing SDNs (Software Defined Networks) in production now, while almost 40% have no intentions whatsoever to go ahead with their deployment (37% of the replies suggested that “SDN will become strategically important” within a two to five-year window). Our skepticism over SDN, especially in the public network is well-documented, and
