PERFORMANCE ADVANTAGE

Distributed Forwarding

Data plane traffic switched at the APs

Traffic can be targeted to another AP, controller or other L2/L3device

Control plane traffic to controller

Configuration control over what traffic gets switched (VLAN profile)

ACLs, QoS and other controls applied at AP

Better Performance Lower latency

Direct switching at AP removes need to shuttle data to controller

No data loss on controller failover

Increased scalability and support for denser deployments Network & controllers carry limited data plane traffic

Supports advanced high density services such as mesh, video and voice

No forklift upgrades for 802.11n

Applications Remote office

Mesh

Video and voice services


Internet

DISTRIBUTED SWITCHING MAXIMIZES SCALABILITY

• All traffic gets forwarded by controller

• Twice the traffic through network core

• 802.11n increases load up to 10x

• Can't scale without expensive upgrades

Centralized-Only Switching Breaks Down

Under Increased Load from 802.11n

Cisco & Aruba

Distributed Switching Handles

802.11n without Breaking Down

Juniper

• Traffic can be forwarded by the AP

• Optimized traffic flows – ideal for voice

• 802.11n has no impact on controller

• Scales in place without upgrades

10x increase exceeds

controller capacity

11n increases load

by up to 10x

Internet


RELIABILITY ADVANTAGE

Controller Clustering

Uninterrupted client connection upon network/controller failure

Controller and AP link failures are handled

N:N redundancy provided for controller failures

Single point of wireless configuration

Multiple controllers are managed as a single entity

Automatic AP Load-balancing

Benefits

Reliability

Most resilient WLAN solution available today

Single point of management

In service network expansion

In services upgrades


Hot Standby Approach - Aruba

RESILIENCY ADVANTAGE OF WLAN VIRTUALIZAION

• Catastrophic failure – dropped user sessions

(imagine voice call)

• APs restart using hot standby controller

• No AP load balancing across controllers

• Fully loaded hot standby required

• Hitless failover – even for active session

(including voice calls)

• APs instantly remapped to in-service controller

• Dynamic AP load balancing across controllers

• No additional equipment required

Controller Virtualization - Juniper


Smart Mobile - Seamless Mobility

MOST ADVANCED MOBILITY ARCHITECTURE

• Dependence on "home" controller

• Inefficient round-trip through network

• No advance knowledge of roaming client

• No immunity to controller failure

• High rate of timeout & dropped calls

Controller A Controller B

Anchored Mobility – Basic Roaming

• No dependence on controller

• Optimized flows across infrastructure
