Transcript

  • 1. MobiMESH Technology Antonio Capone CTO
  • 2. Technology Outline • MobiMESH Network Architecture • Access Network • Backbone Network • MobiMESH Mobility • Management System • MobiMESH Installation • Questions & Answers
  • 3. MobiMESH Network Architecture • Backbone: wireless multihop infrastructure • Access: appears as a WLAN to clients • Wired Backbone integration
  • 4. Access Network • Any Wi-Fi (IEEE 802.11) client can access the network • The Access Network is perceived by clients as a standard Wi-Fi network • The Access network can work in the 2.4 Ghz, 4.9 Ghz and 5 Ghz frequency band, at admin's choice
  • 5. Access Network (2) • All security protocols for access networks are supported: – WEP – WPA/WPA2 (PSK, EAP-TLS, EAP-TTLS, EAP-PEAP...) – MAC ACL – VPN • RADIUS integration for Authentication, Authorization and Accounting (AAA) • Captive Portal support for Hot-Spots
  • 6. MobiMESH Backbone • MobiMESH Backbone constitutes the wireless distribution system • Multi-radio, Multi-hop network • A real, layer 3 network • Main tasks: – Transport access traffic – Signalling – Mobility Management • Radio-Aware Routing Protocol
  • 7. MobiMESH Radio-Aware Routing Protocol • Protocol Features: – Multi-channel: interference aware – Aware of the physical rate of the link • The Idea: Avoid using the same frequency in and out the same node • More interfaces (and frequencies) on a node -> less interference • Most producers (Cisco, Tropos, …) still developing it!!
  • 8. Single Radio Vs Multi Radio • Single Interface: half duplex link, low throughput • Multiple interfaces: contemporary transmission and reception, high throughput
  • 9. Real Mesh Vs Bridged Networks REAL MESH BRIDGED NETWORKS • Layer 3 • Layer 2 • Routing protocol: • Single IP network: – Optimization – No routing, only mechanisms broadcasting – Failure recovery – Bandwidth loss • More Scalable – Manual and slow failure recovery (if any) • Easy management
  • 10. MobiMESH Backbone Security • Router Authentication – MobiMESH Routers are authenticated through digital certificates – No attacker node can enter the Backbone Network • Traffic Encryption – Both data traffic and signalling is encrypted – Ciphering with time-changing key
  • 11. MobiMESH Mobility Management • Access terminals are tracked and their position is known to the Backbone network • Once a terminal changes access point, traffic is routed to the new location • Active connections are not lost! – Max Handover time is around 100ms – Best performance on the market!
  • 12. MobiMESH Management System • The MobiMESH Network is managed through the MobiMESH Management System (MMMS) • Main tasks: – Network configuration – Configuration provisioning – Network management – Network monitoring
  • 13. MMMS: Network Configuration • Every parameter on the node can be configured on the MMMS • Every wireless interface can be configured as a backbone or as an access interface • Every interface can work on both 2.4 GHz and 5GHz frequencies
  • 14. MMMS: Configuration Provisioning • The MobiMESH network is self configuring • It automatically creates the desired configuration • When a node is powered on: – It tries to find the MobiMESH network – It contacts the MMMS and it retrieves its configuration – It applies the configuration – It joins the network
  • 15. MMMS: Network Management and Monitoring • The Network can be managed and monitored through the integrated map • Some administration tools are provided: – Backbone Link Status – Connected Clients list – SNMP Echo test – SSH Console – Watchdog – Node Recovery Mode
  • 16. MobiMESH Installation • MobiMESH Installation is an easy task • When the node is placed on the poles, the Positioning Interface helps pointing antennas
  • 17. MobiMESH Installation (2) • Once MobiMESH Routers are installed and powered on, the network comes up automatically • If any configuration mistake has been made, the watchdog rescues the node: no need of on-site intervention • Remote management
  • 18. Questions & Answers Before moving to the live demo, any question?
