6 Tech Trends to Keep an Eye on in 2018

That time of year has arrived — both to look back at the developments that have come before and to look ahead to the advancements that will arrive as the calendar year passes. But what other leaps forward might we expect in 2018? Let’s take a look at the top picks shared by expert Roger Samara.

Monitoring Network Traffic More Efficiently

The company intranet is growing constantly at the time. Hence, the network administrators have to handle different type of the traffic that is crisscrossing the networks.

Monitoring and analysis of the network traffic are necessary in order to resolve the networking issues more effectively says, Roger Samara. Today's the computers did the traffic analysis. This means they conclude the state of the network at the time when the data packet reaches their destinations.

The Network Traffic Monitoring can be done effectively

Actually, the network scrutiny would be done more efficiently if routers inside the structure can report on their own conditions. Furthermore, this also enables the network operators to address the problem quickly.

Hence, the router industrialists start to equip these networking devices with counters which report the number of data packets router process in given time period. But the number counts are lone so convenient.

Also, this is not practical to give routers a singular purpose monitoring circuit for every new dimension the operators want to make. An alternative to this that these network devices transfer the data packet to the outside servers for composite exploration. But this technique does not work well. This is because, the data center having 1, 00,000 servers may need another 40,000 servers in order to keep up with the deluge of the data packet.

Dubbed Marple - New Approach to Monitor the Network Traffic

Some researchers at MIT, barefoot networks, and Cisco networks introduce a new tactic for the network monitoring. The computer savvy Roger Samara says that this approach endows the flexibility in data collection. Furthermore, it also keeps the circuit intricacy of routers and number of exterior analytical servers low.

This new system contains programming language which permits the network operators to stipulate a wide range of network monitoring tasks. In fact, the Marple only needs a single traffic scrutiny server for every 40 to 50 application servers.

The Idea behind the Marple

The main idea behind this new approach is to do possible analysis on the router itself without any network delays. Plus, to send the exterior server summary instead of raw packet data. This will result in saving both the processing time as well as bandwidth.

In fact, Marple is built to analyze the transmission of every computer transferring data through the router. This is according to Roger Samara that the problem is that this networking device has the memory to store only 64,000 connections.

This system is able to monitor more transmissions through a variation on caching i.e. a common computer science technique. Here, the Marple kicks off the data for newer data.

Wrapping Up

From hundreds to thousands of processors and Ethernet to ATM, the administrators need some tools for monitoring the network traffic. Actually, the main purpose of network traffic monitoring is to count the IP traffic between individual’s local area network and Internet. The Marple system endows the real-time traffic accounting as well as monitoring.

The FCC Repealed Net Neutrality — Here’s What That Means for You

In a move that could fundamentally reshape the internet — and spur a new wave of legal wrangling — the Federal Communications Commission voted Thursday to repeal its net-neutrality rules.

Here Roger Samara is sharing his vision on net neutrality, the proposal and what’s likely to happen next.

How to Protect your Email from Viruses and MalWare

Roger Samara is a Computer Technician with 10 years of experience. He is the master of Computer world and passionate about new technologies his field.

Once upon a time, email was considered to be a pretty safe communication medium. For those still using PINE or some other text-only mail client, it still is, says Roger Samara. But for the rest of us, who want to take advantage of all the advanced features of modern email client software, opening an email message can be a scary experience.

Roger Samara | 5 Ways to Enjoy Virtual Reality

Technology is probably one of the best creations human beings have ever made. Not only is technology able to connect people but also gives us exposure to sights, sounds, and feelings that we haven’t experienced in our lifetimes.

With Virtual Reality, technology now allows us to experience a close to life environment in an imaginary setting. As per Wikipedia, Virtual reality (VR) typically refers to computer technologies that use virtual reality headsets to generate the realistic images, sounds and other sensations that replicate a real environment or create an imaginary setting.

Though VR is still relatively new to the public, there are already a lot of different ways to enjoy VR. Here are some of the virtual settings and activities that you can experience:

1. Flying

Ever dreamed of flying? Well, here’s your chance to experience how it feels like. Using VR glasses, you will be able to fly. VR glasses presents to people a very realistic image or video that helps wearers build the momentum and excitement for the whole experience.

Aside from that, if you want to experience flying, you may try this new invention made by the researchers of Zurich University’s Interaction Design Program called Birdly. Birdly is a Virtual Reality console that allows a person to lie on a padded, cross-shaped apparatus and gives people the sensation of flying over buildings or across country sides.

2. Swimming

In other cases, a VR headset will also let you experience swimming. But it’s more than that. It will also let you feel what it’s like to be swimming under oceans with dozens of fish, sharks, and whales swimming around you. You will definitely feel like being underwater because you will be able to see and hear the beauty and sounds of these sea creatures.

3. Roller Coaster

If you’re just at home sitting on your couch and have got nothing to do, why not ride a roller coaster? Yes, it’s just that easy when you have your own VR headset! Start feeling the gravity as the coaster twists and turns upside down. There are many VR headsets that have built in games where you can truly experience an extreme roller coaster ride. There is also a simulator called “No Limits 2” which will let you experience roller coasters on a whole new level.

4. Skydiving

Skydiving is an extreme sport that some people can only dream of doing because it is really expensive. If you’re looking for a cheaper (and also much safer) way to experience skydiving, then VR is the way. Fly up to high altitudes with “Volo Airsport”, a physics simulator that lets people hang on to their life and experience skydiving.

5. Flight Zombies

If you are the type of person who is fascinated by the idea of a zombie apocalypse, then VR is your closest way to experience it. So, if you want to experience what it’s like to be in a scene of “The Walking Dead”, download “Zombie Shooter”. It is free on Apple and lets gamers to shoot and kill zombies that are chasing them through the VR headset.
