Scaling Infrastructure & Management

Questions: • How does it scale? (Architecture & Management Systems)• Does it support all features with distributed forwarding?• What does the cost model look like as it scales?

• Redundancy? Branches? Feature licenses?• Does the solution become more complex as it scales?

• Additional components required? • Does the solution have a scale limit?

Deployment

Questions: • How are you going to deploy your network? Big bang or slow roll?• How many remote sites? What level of IT resources at each one?• How many network components are needed at each location?

Guests

Questions: • How will you offer guests Internet access via the Wi-Fi infrastructure?• Are there different types of guests? Parents, contractors, visiting

employees?• Will guest access be Authenticated? Encrypted?• Will guests be allowed different types of access based on device type,

location, time? Rate limited? Content filtered? Individualized security?• Will guest access be uniform across all locations?

Planning & Tracking

Questions: • Comprehensive predictive planning tool available?• Infrastructure devices, client devices, & interference

sources reported on live floor plan?• Real-time device tracking(RTLS) on a live floor plan

supported?

Troubleshooting

Question: How and from where will you troubleshoot problems?

© 2011 Aerohive Networks CONFIDENTIAL 14

Simplicity

Questions: • How simple is the solution to design, deploy, expand, manage, &

troubleshoot?• Can it be managed from a mobile device? From anywhere?• How many people does it take to operate the network?

• How much time will they have to spend each day on the Wi-Fi?• Is the system appropriate (features/manageability) for the

market?

Centralized Control- Centralized Intelligence

- Radio Resource Mgmt (RRM)- Authentication & Key Mgmt- WIPS, RTLS, L3 roaming, & a few others- Tremendous design complexity- Single points of failure, & redundancy is expensive- Bandwidth bottleneck, & won’t scale cost effectively- Limited features when distributing forwarding

Autonomous APs-Scale linearity (1 AP at a time)-Low cost (no extra hardware)-Limited intelligence-No RF / network awareness -Managed individually

Cooperative Control- Distributed Intelligence

- Fully distributed control & data planes- All enterprise-class features- Works like a distributed computer- Best-path forwarding & inherent resilience- Load balancing, band steering- Linear, unlimited, & cost-effective scaling- Simplistic deployment and management- Private & public cloud mgmt options
