The Internet of Things (IoT) is arguably at the peak of the hype cycle, but while much of the discussion is focused on the "things" themselves or the networks required to connect them, the real value of the IoT will come from the cloud and data analytics behind the scenes. The big idea of the IoT is that capturing data from devices is cool, but if we are just collecting data, it's just telematics. The real promise of IoT is how you tie that data together with insight and intelligent action. Technically, we've been connecting "things" for years for M2M apps like utility grid sensors and fleet tracking. And while we're now connecting more and more things with more sophisticated apps, the real change is what's happening behind the scenes. What IoT is really about now is large complex data flows, which is enabling new types of insight and business opportunities that previously weren't available. The "cloud" is the enabl...

The IoT is expected to continue its trans-formative potential across industries in the foreseeable future, with 2016's momentum expected to lead spending in the IoT space. The major IoT opportunities will be in the deployment and management of IoT projects. This will lead to ad requirement for new skill sets which are currently scarce in the APAC region. There will also be a shift towards computing decentralization as the IT industry gradually shifts towards using more IoT technology. Example include P2P networks becoming more widely used, allowing connected devices to communicate directly with each other rather instead of being routed through a centralized data center. IoT will heavily influenced by "cloudification" and this will lead to its own set of challenges. These include the large amounts of data involved, realignment of existing processes and security solutions. Cybersecurity is also paramount as the security paradigm is increasingly shifting to ph...

The Internet of Things (IoT), also known as Machine-to-Machine (M2M), is hardly a new market for satellite Industry. M2M has been around for years in the form of SCADA (Supervisory Control and Data Aquisition), an industrial control system for remote monitoring and control. The M2M protocol is designed to be quite compact and data rates are low which have long made this technology cost effective over satellite. Where IoT differs is in volume. A typical SCADA system might involve a few hundred sensors across a pipeline network. Today's IoT system are scaled for thousands of endpoints, and are designed for flexibility in terms of bandwidth. For example, an IoT system may transmit low-resolution video but automatically switch to high-resolution video on a single camera when triggered by a motion sensor. Growth in IoT is projected to be astronomical : anything from 25 billion to 50 billion connected devices by 202, depending on which survey you read, f...

MTU (Maximum Transmission Unit)  MTU is the size (in bytes) of the largest protocol data unit that the layer can pass onwards. MTU parameters usually appear in association with a communications interface (NIC, serial port, etc.). Standards (Ethernet, for example) can fix the size of an MTU; or systems (such as point-to-point serial links) may decide MTU at connect time. A larger MTU brings greater efficiency because each packet carries more user data while protocol overheads, such as headers or underlying per-packet delays, remain fixed; the resulting higher efficiency means a slight improvement in bulk protocol throughput. A larger MTU also means processing of fewer packets for the same amount of data. In some systems, per-packet-processing can be a critical performance limitation. To test your MTU connection, we can use ping test with command : ping xxx -f -l yyy while yyy is packet size.  example : C:\Users\admin>ping yahoo.com -f -l 1472   Pinging yahoo.com [209...

Ping..... Ping is one of the usefull and effective command in determine network test connectivity with another IP host. Typing PING followed by specific IP address at command prompt will immediately tell whether there is connectivity between your computer and the other host. Ping test is often referred as testing the protocal stack, because the ping command moves from Layer 3 OSI model to Layer 2 and then Layer 1. Ping uses the ICMP protocol to check for connectivity. Please note... ping will not always pinpoint the exact of the problem in the network, but it can help identify the source of the problem, one of important first step in network troubleshooting. Ping command There are also a number of options that you can use with the PING command. The available options are listed below. -t Pings the specified host until stopped -a Resolves addresses to hostnames -n count Number of echo requests to send -l size Send buffer size -f Set Don’t Fragment flag in packet -i TTL Time ...
