Big Data IntroductionCharacteristics of Big Data ChallengesBig Data Transmission NetworkBig Data Network FutureQ/A
Who’s Generating Big Data
Social media and networks(all of us are generating data)
Scientific instruments(collecting all sorts of data)
Mobile devices (tracking all objects all the time)
Sensor technology and networks(measuring all kinds of data)
The progress and innovation is no longer hindered by the ability to collect data But, by the ability to manage, analyze, summarize, visualize, and discover knowledge
from the collected data in a timely manner and in a scalable fashion

How much data?Google processes 20 PB a day (2008)Wayback Machine has 3 PB + 100 TB/month (3/2009)Facebook has 2.5 PB of user data + 15 TB/day
(4/2009) eBay has 6.5 PB of user data + 50 TB/day (5/2009)CERN’s Large Hydron Collider (LHC) generates 15
PB a year
640K ought to be enough for anybody.
Characteristics of Big Data: 1-Scale (Volume)
Data Volume 44x increase from 2009 2020 From 0.8 zettabytes to 35zb
Data volume is increasing exponentially
5
Exponential increase in collected/generated data
Characteristics of Big Data: 2-Complexity (Varity)
Various formats, types, and structures
Text, numerical, images, audio, video, sequences, time series, social media data, multi-dim arrays, etc…
Static data vs. streaming data A single application can be
generating/collecting many types of data
6
To extract knowledge all these types of data need to linked together
To extract knowledge all these types of data need to linked together
Characteristics of Big Data: 3-Speed (Velocity)
Data is begin generated fast and need to be processed fast
Online Data AnalyticsLate decisions missing opportunitiesExamples
E-Promotions: Based on your current location, your purchase history, what you like send promotions right now for store next to you
Healthcare monitoring: sensors monitoring your activities and body any abnormal measurements require immediate reaction

Big Data Transmission
Data transmission with high-value-per-bit SONET/SDH (Synchronous Optical Network)
Lower-cost-per bit technologies Carrier Ethernet.
Networking switching is moving rapidly to 10-40 Gbps
Big data requires big networks.
Big Data- Network
However Ethernet on its own is not sufficient to handle the torrent of Big Data.
Network architectures also need to change to become flatter and more flexible.
Basic idea:Push computing to data, not pushing
data to computing.
