What does AirMatch do differently? 10:00 GMT | 11:00 CEST | 13:00 GST NOV 28th, 2017 Presenter: SAJIN NAIR [email protected] 1 Agenda Introduction AirMatch vs ARM Setup AirMatch Enable AirMatch and Profiles

AirMatch Optimization Workflow AirMatch Input Metrics Logs Troubleshooting 2 Ideal way to solve a Jigsaw puzzle? 3 Key Considerations with ARM

A decentralized service; each individual radio makes its own decision ARM is reactive in nature, cascading affects Future spectrum enhancements, Lack of bandwidth planning Asymmetric EIRP planning which may not provide optimal client roaming behavior Cascading affects 4 What is AirMatch ? A centralized RF optimization service Newly defined information collection and configuration deployment paths

Models and solves the network as a whole Results in better channel, bandwidth and EIRP plan for the network 5 Advantages of AIRMATCH Clean slate RF optimization service Long term network stability & Performance Holistic view of network Different mode of data collection and calculation Once a day optimization Reactive optimization

HOW AIRMATCH WORKS? 9 AirMatch Workflow 1 Air Match calculates solution for each AP AP sends RF statistics as AMON messages to Managed Devices (MDs)

MM Standby MM Master 2 The MDs forward the AMON messages to Mobility Master (MM) VRRP Cluster 1

3 AirMatch calculates an optimal RF solution 4 Mobility Master pushes the solution down to MDs 5 MDs send dot11 radio profile to APs

MD1 MD3 Cluster 2 MD2 MD4 MD1 MD3

MD2 MD4 10 AIRMATCH INPUT METRICS 11 AirMatch Input Metrics

Radios operating condition ( in reporting_radio) Radio Feasibility Neighbor Measurement ( in pathloss_history and nbr_pathloss) User defined metrics include EIRP and Channel Bandwidth 12 What Information flow at the high level

Radio Membership Link Path-loss How Input

APs AM -> AMON -> LC LC -> AMON -> SC SC -> DB Output Process

SCs Airmatch solver Calculates solution Triggered by external event Stores it back to the database Bandwidth Channel EIRP

SCs Airmatch deploy queries and fetches info SC AMAPI to SAPM SCs SAPM to LC LCs SAPM to APs SAPD 13 Feasibility Report

Field Description Reporting Radio Base Mac Address Introduces Mobility Controller or Managed Node which is completely managed by MMChannel using Zero Touch Provisioning unlike 6.x Master-Local

List List of first 20MHz Channels List of supported bandwidth The MM can only be a VM and not a controller Bandwidth EIRP Range Range of valid EIRP values 14

TIMING OF RF PLAN CHANGE 8.0.1 16 Timing Of RF Plan Change Incremental Optimization On-Demand Optimization Reactive Optimization Scheduled Optimization 17

On-Demand Optimization 1 airmatch runnow full- performs the same quality optimization that would be done in a periodically-scheduled optimization 2 airmatch runnow quick- quick-and-dirty solution, random channels, but computes correct EIRP for cell sizes 3

airmatch runnow incremental- Only considers new APs added, keeping the existing APs solution intact 18 Reactive Optimization Mobility Master/Standby AM 1 AirMatch allows event driven channel

changes 2 Upon noise & radar detection, the AP will change channel 3 Channel with minimal interference index will be chosen AM

MC1 4 Any channels with radar detected in the last 30 mins are excluded Channel 36 Channel 44 Upon radar detection, if there is noise on all channels where there is no radar detected, the AP will have no choice but to choose the channel with noise.

19 Incremental Optimization During Initial Phase Workflow Headquarter 1 First batch of APs joining the MC for the first time are called leading pack 2

Initial phase defined for 8 hours; solution checked every 30 minutes 3 AirMatch algorithm runs to check for newly joined APs Mobility Master/Standby AM AM

AM MC1 4 MC2 If yes, only newly joining radios will be assigned with a new RF plan 20 Scheduled Optimization

1 AirMatch, by default, is scheduled to run once a day Controls radio resources such as channels, channel bandwidths and EIRP of a WLAN Consumes radio membership and link pathloss Provides centralized computation 21 Workflow of RF Plan Change 1

Incremental Optimization starts Headquarter Mobility Master/Standby AM 2 After end of initial phase, you can run on-demand optimizations 3

Event triggered changes lead to reactive optimizations 4 If no event occurs,/no on-demand optimizations, then algorithm runs on schedule. AM AM


This step enables the Mobilty Master to receive reports from Aps. Add the CLI in the Device node. mgmt-server primary-server profile default-amp If default-amp is not configured, please enable stats. As this is needed to AirMatch to receive amon messages. 24 Quality-threshold and Stats 1 2 Quality-threshold

Checks percentage change against current state Stats Enabled Interval of stats sent to MM 25 How & What summary of information from an AP? #show ap debug airmatch-report ap-name Multizone 26

Does the AP implement solution from Master? 27 How channel and power where changed? 28 AirMatch Solution 29 AirMatch History
