A phenomenon that occurs in the current era of big data in which the information exchange process utilizing, and the growth of the internet network traffic has nearly triple annually based on Cisco®, diverse applications accompanied by the latest features was born and continues to grow almost every day and becomes a challenge for performance both in terms of network design model and optimization, the readiness of the device and application support low overhead to supports 3V challenges (volume, velocity, and variety) rather than exchanging packets in a network.

The network also faced with the challenges regarding whether it is worthy enough devices in the network to handle traffic increasing it. The promise of data driven decision making is now being recognized broadly, and there is growing enthusiasm for the notion of “Big Data”. While the promise of Big Data is real, for example, it is estimated that Google alone contributed 54 billion dollars to the US economy in 2009, there is currently a wide gap between its potential and its realization (Agrawal et al, 2012).

The challenges of network changes on future significantly is covering readiness of the infrastructure, the needs and involvement of users on the network, a growing number of new devices, and data transmission traffic is increasing, where the Global Internet Traffic predicted at the end of 2015 three billion people will reaching quadruple 1 zettabyte per year.

Annual global IP traffic will pass the zettabyte (1000 exabytes) threshold by the end of 2016, and will reach 2 zettabytes per year by 2019. By 2016, global IP traffic will reach 1.1 zettabytes per year, or 88.4 exabytes (nearly one billion gigabytes) per month, and by 2019, global IP traffic will reach 2.0 zettabytes per year, or 168 exabytes per month. Global IP traffic has increased fivefold over the past five years, and will increase threefold over the next five years. Overall, IP traffic will grow at a compound annual growth rate (CAGR) of 23 percent from 2014 to 2019.

Refer to the paper “Cisco VNI: Forecast and Methodology, 2014–2019.” To understand the magnitude of IP traffic volumes, it helps to look at the numbers in more familiar terms:

• By 2019, the gigabyte equivalent of all movies ever made will cross the global Internet every 2 minutes.
• Globally, IP traffic will reach 511 Tbps in 2019, the equivalent of 142 million people streaming Internet HD video simultaneously, all day, every day.
• Global IP traffic in 2019 will be equivalent to 504 billion DVDs per year, 42 billion DVDs per month, or 58 million DVDs per hour.

Regional Highlights

IP traffic is growing fastest in the Middle East and Africa, followed by Asia Pacific. Traffic in the Middle East and Africa will grow at a CAGR of 44 percent between 2014 and 2019.

Summary of regional growth rates:
• IP traffic in North America will reach 49.7 exabytes per month by 2019; growing at a CAGR of 20 percent.
• IP traffic in Western Europe will reach 24.7 exabytes per month by 2019; growing at a CAGR of 21 percent.
• IP traffic in Asia Pacific will reach 54.4 exabytes per month by 2019; growing at a CAGR of 21 percent.
• IP traffic in Latin America will reach 12.9 exabytes per month by 2019; growing at a CAGR of 25 percent.
• IP traffic in Central and Eastern Europe will reach 16.9 exabytes per month by 2019; growing at a CAGR of 33 percent.
• IP traffic in the Middle East and Africa will reach 9.4 exabytes per month by 2019; growing at a CAGR of 44 percent.

A big problem arises of how to provide a connection that is reliable traffic network with a large bandwidth consumption is also supported by the availability of large data storage size , because the current utilization data format based on huge audio and video that has increasing in the networks. Big data brings new traffic and performance related challenges and calls for a deep revisit of the methodological tools that were traditionally used for performance evaluation and traffic engineering. New models and approaches are needed to investigate big data characteristics in terms of 3V (volume, velocity, and variety) and their impact on network performance, new solutions have to be designed to efficiently and securely manage information, new techniques are needed to support all phases of network planning, design and optimization.

Each year, various new devices in different form factors with increased capabilities and intelligence are introduced and adopted in the market. A growing number of M2M applications, such as smart meters, video surveillance, healthcare monitoring, transportation, and package or asset tracking, also are causing connection growth.
