The Dream Fast, secure, ubiquitous access to applications hosted in the cloud
The Reality Protocols inherent to Internet architecture limit data transfer speed
Users are widely/globally distributed Variety of connection types exist (cable, DSL, etc)
Traffic patterns are highly variable
The Result
Cloud services suffer poor Quality of Experience Upload experience particularly limited
Bandwidth is highly over-provisioned
Users often deterred from popular data (i.e. videos)
Network Issue for SaaS & Cloud Applications

Reduced Revenue Opportunities Limited reach to a global market
Difficulty differentiating service
Suboptimal customer usagemetrics
Increased Operating Costs
More support calls / emails
Risky and costly bets on newdata center sites
Bandwidth at data centersheavily over-provisioned

Business Issues Asankya Impact
Slow Data TransferEnd-users limited their usagebecause upload speed was tooslow to handle their movies
and pictures
Asankya improvesspeed by 10x with nosoftware integration.
Limited Revenue GenerationEnd-users needed a betterreason to convert from freetrials to a paid subscription
Asankya enables adifferentiated premiumtier of service.
Global ConsistencyGlobally distributed user basenecessitated many regional
data centers
Asankya decreases thedata centers needed byincreasing the reach of
each data center.

Adding more bandwidth does not solve theproblem
That only increases the last mile
Customer does not control the middle mile
Bottlenecks Have Moved to the middle mile
ISP to ISP interconnects hot potato routing
Overloaded routers default route is not alwaysthe best route
Protocols Use the Network Inefficiently
Network congestion causes protocols to slow
Network delay causes protocols to use networkinefficiently

The origin and destination nodes actas TCP proxies for data.
Asankya transport algorithmsoptimize the utilization of the
aggregate capacity between theorigin and the destination.
Algorithms include
Accelerated start-up, advancedcongestion reaction
Quick and reliable loss detection
Multi-state operations
Auto-tuning, multi-stage flow control

Intelligent Transport Detail
The TCP transport layer protocolhas severe deficiencies inachieving high utilization when theend-to-end bandwidth, delay orloss-rate is high
Traditional TCP optimization solutions can onlytweak TCP in two ways to improve utilization:(1) Increase advertised flow control window size
through window scaling; and(2) Selective acknowledgements in addition to the
default cumulative acknowledgements
Intelligent Transport is designed withoutTCPs limitations. Its elements include:
(1)Accelerated start-up, ratemaintenance,
(2)Super-linear increase andproportional decrease congestioncontrol
(3)Fast, robust loss detection and
recovery(4)Auto buffer management(5)Multi-state operations use RAPID
scheduling algorithm to split physicalflows into multiple virtual flows

All overlay mesh nodes act as routereflection points on the AsankyaRAPIDnet network.
The origin node uses the reflection
nodes to create multiple overlaypaths to the destination node.
It then uses RAPID to successfullyharness and aggregate thethroughputs available along themultiple paths.

RAPID moves the seatof intelligence to thesending side in usingmultiple paths
The RAPID protocol
(1) characterizes available paths interms of throughput, delay andloss performance, and
(2) stripes packets over the pathssuch that (with a high probability)they arrive at the receiving end in
the correct order
A safety net reassemblyprocess at the receivingend guarantees no out oforder delivery
RAPID scheduling algorithm decides(1) how much to send along a path(2) in what order to send them to
achieve in-order delivery

Asankya Unique Benefits
15
Asankya Benefit Why? Who Cares?
Improves throughput 10x Best in class today is 1.5 to 2x. For manybuyers, performance is #1 criteria and 2x isnot enough.
Corporate IT, SaaS, dynamic web sites,commerce sites, cloud storage and compute
Accelerates all encryptedtraffic
WAN optimization techniques (CIFS, MAPIacceleration, compression) cannot be doneon encrypted traffic
Corporate traffic moving to the Internet needsencryptionTraffic also needs speed improvement to matchprivate network speeds.
Two-way Dynamic Increasingly applications are morecollaborative and more dynamic, whichmakes them two-way and non-cacheable.
Companies wanting to use Sharepoint,videoconferencing, storage (uploads), andcommerce (non-cacheable) apps.
Application Independent WAN Optimization improvements areprotocol and application specific.
Companies with more than one application orapplications that use unique protocols.
Improve throughput at 'in-country' distances
Existing WOC and Overlay Networkofferings do not improve in-country/in
continent traffic .
Half of application traffic typically happens in-country even small improvements have a big
effect.
Consistent performanceglobally
Traditional Network Overlay Services onlyimprove where their systems have beendeployed and may miss large portions ofthe global network.
Online services dont control where their uses
come from need best performance fromanywhere in the world.
