AgendaAgenda
Enterprises have tactically deployed WAN Optimization Controllers at sites to improve application performance. While this approach may provide immediate relief, it will not address the application performance control that a global enterprise needsperformance control that a global enterprise needs.
What are the challenges of a tactical approach to WOCs?What are the challenges of a tactical approach to WOCs?
How does an Autonomic WAN Optimization System overcome these?

Limited scalabilityLimited scalability
Traditional systems are “box based”B b d t i l t f fi tiBox based systems require a lot of configurationBox based systems lack global visibilitySimply accelerating traffic without knowing what/where/why will lead to a bigger problem later
Box based QoS mechanisms rely on policiesQ y pNumber of policies can be restrictive (just a few 1000s)In large datacentres, this leads to generalisationNeed to constantly keep policies current (manpowerNeed to constantly keep policies current (manpower intensive)

High management costsHigh management costs
Optimization methods need to be configured individuallyC fi ti d t b i t t ll t llConfiguration needs to be consistent across all controllersCentral manager not always helpful as local parameters still need to be set (WAN access, limitations etc)
Not easy to adapt to changes in the WANWANs are constantly evolving entities, changes happen all y g , g ppthe timeNew application roll out can cause huge workload in updates and reconfigurationgEach change can have same cost as original deployment

Traditional WOCs struggle to deal with meshed networks and meshed traffic flowsmeshed traffic flows
Traditional systems are designed to work point-to-point or in hub and spoke (star) networks
S l ti d l t d t ti li i l d t t dSelective deployment and static policies lead to unexpected results
Selective deployment denies unequipped sites the full benefitStatic policies cannot cope with modern dynamic WANs

Significant investment costsSignificant investment costs
Despite cost decreases, WOCs are still expensive devicesE i ll i dditi t b h ffi tEspecially in addition to a branch office router
To get optimization benefits, you need to deploy at least one device in EVERY location
This is not practical in many networks
