Switching to Data Vision

One of my favorite essays during school days used to be about Television. I still remember writing about the TV in Hindi. Invented by John L. Baird, if my memory serves me correctly. Looking back in the last 30-40 years, we have moved from no TVs, to TV being a novelty, to CRT TV sets being the norm (who can forget Dyanora?) and nowadays, to LED TVs. What next? Of course, 4K Ultra HD TVs are already here. We will move away from the cable TV or even the need for a satellite Dish enabled TV set in the future. It may sound alarming, but it is going to be the reality sooner or later. No more TV shows, a dime to the dozen, repeated in multiple languages and broadcast over an untold number of channels. Early age TVs used to have 12 channels and a remote control was unheard of. Within a few years now, we have hundreds of

High Performance Networking trends

Over the past couple of decades, the Computer networking industry has seen many trends come and go. Looking at how things stand today, the core skill sets of Routing and Switching look likely to become dated as the number of experts proliferate the market and the task of routing the packets through the Internet has become a commodity for so many deployments. Fundamentally, the core job of routing remains the same, from the perspective of a device. For it, a packet (or data) comes in and it needs to make a decision on where to send it out to. The USP for any device resides in the speed with which it can make this decision and the speed with which the packet can be forwarded out another interface, towards its ultimate destination. As with so many other technology industries that reaped the benefits of Moore’s law, it was the same with the High Performance Networking industry. Shrinking space for the

Net Neutrality

The recent FCC ruling in favor of Net Neutrality is an interesting decision. The Federal Communications Commission (FCC) of the United States passed a rule that the Internet Service Providers should always act in “public interest” – similar to telephone lines. What this means is that the Service Providers such as AT&T can not enter into an agreement with Content Providers such as Netflix, Google, etc. where their content is given preference over other Internet sites. This ultimately translates to a single pricing structure for all end users irrespective of the content that they are accessing over the Internet. The ruling has been touted as a victory for end users and a rap on the knuckles for Service Providers who want to impose a variable pricing scheme for Content Providers. I don’t see it the same way necessarily. I think it makes sense to make end users pay for the service that they are receiving. Although we do not have

Networked road travel

Continuing from my previous blog post on connected cars, the allure of the networked cars is too strong to resist for the Computer Networking engineer in me. Once the driverless cars are connected to the grid and are able to decide on an optimal route to take to reach a destination, the problem of getting the cars there becomes one that has been solved in the Internet Protocol (IP) routing world a few decades ago. While the Internet itself functions on the ability of the data to be split into “packets” that are transported from a source to a destination via routers that decide on the shortest path to take to reach the destination, it is a very real possibility to apply this thought to the world of traveling. The road networks that exist today offer a ready made infrastructure for travel without drivers and with a reduced incidence of accidents. Smart cars, which would be connected to a GPS
