WLAN : Fiabilité et Performance VVT Edition 2017 : Luminy Juin, 2017
Agenda 1 Les Nouveaux Challenges 2 3 4 5 Problématique RF en HD Fiaibilité avec le Clustering ArubaOS 8 Feature Ressources 2
Les nouveaux challenges dans les environnements haute densité Amélioration de la fiabilité à tous les niveaux Contrôles automatisés pour améliorer l'expérience utilisateur Simplicité des opérations et flexibilité du déploiement Sécurité Réseau Avancée 3
Simplification et évolutivité des infrastructure WiFi grâce la virtualisation Mobility Master (HW/VM) Mobility Controller Virtual Appliance Autonomous APs 2002 2016 Controller based WLANs to enable seamless mobility, ease of management and improved security 4
Pourquoi les environments HD (High Density) sont complexes à apprehender? Shared Medium Access Limited Number Of Channel Co-Channel Interference Limited number of 5 Ghz capable clients Bad client behavior Application Delivery Thoughput Requierments 5
Plannification and Design pour des environnements HD Capacity Planning Device Count Channel Count Target performance per Device Total reserve vs. capacity Validation of capacity goal RF Design Stratégie Overhead coverage (ceiling mount APs) Side coverage (wall mount Aps) Floor coverage (under the floor) Total reserve vs. capacity 6
RF management for better user experience Adaptive Radio management ( ARM) Adaptive Radio Management (ARM) AirMatch Centralized Channel, Channel width and power planning for APs ClientMatch Connect clients to the best available AP Adaptive Radio Management Adjust channel & power planning to provide better user experience Optimize spectrum usage Reduce co-channel and non Wi-Fi interference AirTime Fairness - assign all Wi-Fi clients on an AP an equivalent amount of air-time 7
AirMatch : Network controls for mobility Automated high density RF optimization with AirMatch Collect RF statistics Next-gen self-optimizing RF planning - enhancement to Adaptive Radio Management Virtual Mobility Master Even channel assignment, dynamic channel width adjustment and automated power planning for APs Enhanced user experience while roaming in large dense environments Optimize RF plan 10
Meilleurs repartitions des utilisateurs sur l infrastrcuture Predictable Wi-Fi performance across the network Intelligently steers devices to the best AP Reduces sticky clients issues => fewer helpdesk tickets No client-side software required REAL-TIME RF CORRELATION DEVICE TYPE LOCATION CONGESTION INTERFERENCE MU-MIMO Aware 11
La visualization et la prioritization pour controller les flux à l accès High priority real-time Medium priority Lower priority Automatically identifying traffic and prioritizing traffic per user and device 12
La disponibilité : Pourquoi le Clustering? Meilleurs experiences utilisateurs et fiabilité dans les environnements HD Mobility Master/Standby 1 Stateful Client Failover User traffic uninterrupted upon controller failure 2 Seamless Campus Roaming Clients stay anchored to a single Mobility Controller when roaming across controllers 3 Client Load Balancing Users automatically load balanced across cluster members MC MC MC 4 AP Load Balancing APs are automatically load balanced across cluster members 16
Simplified Operations Simple to operate Modernized UI with quick workflows Hierarchical configuration Centralized visibility and monitoring Zero touch deployment for Mobility Controller Improved upgrades In service upgrade AppRF, AirGroup without interrupting end users Multi-version support under MM Muli-tenant wireless network w/ MultiZone Multiple SSIDs on one AP with different controllers Federal, retail or multi tenant deployments 19
Liste des features de la v8 vs v6.x v6.x v8 sans Mobility Master v8 avec MM Client Match et ARM Policy Enforcement Firewall (stateful FW, concentrateur VPN, RBAC) AppRF WebCC Flexibilité de mode de management RBAC grace à PEF Support des UC over Wi-Fi Predictive performance monitoring with Aruba Clarity (since 6.4.3) New UI Contrôleurs virtualisables Hierarchical config (global and local) Custom AppRF signatures and categories Centralized licensing with pools Zero touch provisioning Intelligent bandwidth management on the WAN Always-on network during controller failure 3 rd party integration with NBAPI for better visibility and monitoring Automated RF management with AirMatch Multiple tenants on the same access point with MultiZone In-service upgrade Awareness for Wi-Fi Calling, Cisco Jabber and custom apps Centralized visibility 62
