Lets talk about.. A mice..& An Elephant
(I am not kidding..)

A *Closer* look ..
Short-live TCP connections <1 sec Causes timeouts (due to
3WHS)
Long lived TCP connections >1 hour Consistent, but take huge
network resource

Issues at Spoke End Application performance
Bandwidth choking Latency/jitter/chatty applications
Complex Infra Different types of servers Storage
Data Security? Compliances ?

Issues at Spoke End continued..
QOS ? Reactive measure Almost useless in solving congestion issues
Increase Bandwidth ? Is not a solution
Rise of hybrid networks.

WAN Acceleration?
Techniques for increasing data-transfer efficiency across WAN
At core is WAN Caching
Maturing at a good rate

WAN Acceleration continued..
Kick in Wan accelerators & we have got –
Less local servers
Achieve LAN Level app performance
Centralize
Converge
Preserve services

Wan Optimization Traditional Wan Optimization
Results Changes header info Applications break, services may not work *Extra* integration required Moooore downtime

Wan Optimization Continued..
Latest Deployment
Results NO header changed*
NO app misbehavior*
Data Offloading Less headaches
*till the time your connectivity is stableImage Credits : Cisco

The Techniques
Selective Acknowledgement
Window Scaling, Protocol matching
Latency Mitigation
Reduce Data Redundancy

The Techniques continued..
Pattern Matching
Fingerprinting & Reconstruction
Load Shedding
Chunk Storing
& much *much* more..

Bottomline• Is one of the next big things
• Need of hour in complex hybrid networks
• BigData over WAN?
