  2. Module Outline • Service Controller Solution • Layer 2 Network Deployment Scenario • Layer 3 Network Deployment Scenario • A3 ACS Solution

  3. Service Controller Solution RADIUS or Active Directory in the existing network as authentication server Multiple SSID for different groups of client to access; e.g. staff and guest Each group of client is only allowed to access specific network subnets Different authentication method can be applied to different SSID

  4. Layer 2 Network Deployment Scenario Deployment scenario: Enterprise only one or several buildings network based on layer 2 connection. Solution 1: SC internet port behavior as network backhaul, and LAN port connect to AP. Solution 2: one of SC ports behavior as network backhaul.

  5. Layer 2 Network Design Intranet for staff Ingress VLAN 1 Egress VLAN 10 Client IP subnet 192.168.1.x AD or RADIUS Authentication Allowed access intranet and internet Internet for guest Ingress VLAN 2 Egress VLAN 10 Client IP subnet 192.168.2.x SC Local account HTML-Authentication

  6. Layer 2 Network Solution I DHCP server Intranet Router Firewall Radius Server Active Directory VLAN 10 VLAN 20 Service Controller Internet Port: VLAN 10 & 20 LAN Port: VLAN 1 & 2 Management Server VLAN 100 VLANSwitch VLAN 1, 2, 100 Altai AP VLAN 1 VLAN 2 VLAN 100 Trunk Port Trunk Port Trunk Port SSID_Intranet 192.168.1.x VLAN 1 SSID_Internet 192.168.2.x VLAN 2 Management SSID 192.168.100.x VLAN 100

  7. Layer 2 Network Solution II DHCP server Intranet Router Firewall Radius Server Active Directory VLAN 10 VLAN 20 Management Server VLAN 100 Egress: VLAN 10 & 20 Ingress: VLAN 1 & 2 VLANSwitch Network: VLAN 10,20 SC Port: VLAN 1, 2, 10, 20, 100 AP Port: VLAN 1,2, 100 Service Controller Altai AP VLAN 1 VLAN 2 VLAN 100 Trunk Port Trunk Port Trunk Port SSID_Intranet 192.168.1.x VLAN 1 SSID_Internet 192.168.2.x VLAN 2 Management SSID 192.168.100.x VLAN 100

  8. Layer 2 Active Directory authentication Procedure User User associate with wireless network EAPOL start EAP Response/identity EAP response DHCP request AP EAP Request/identity Redirect the request to Service Controller EAP request EAP success Service Controller EAP Response/Identity Over AD EAP Response over AD AD Server EAP request over AD EAP success over AD and user configuration DHCP server Response DHCP request Send IP address back

  9. Layer 2 HTML authentication Procedure User User associate with wireless network Send DHCP request User attempts to browse an Web site User Login Transport page sends request for session and welcome page AP Redirect the request to DHCP server Redirect the request to Service Controller Service Controller Request is intercepted Login page is returned User login info is sent for authentication Transport page is sent Session and Welcome pages are sent Local account Login approved. User configuration setting are returned DHCP server Response DHCP request Send IP address back

  10. Layer 3 Network Deployment Scenario Deployment scenario: University & enterprise multiple buildings network based on layer 3 connection. Solution 1: Two buildings connect to each other based on layer 3 connection (Traffic forwarding based on IP address). Since SC establish communication with AP only by VLAN, each SC should be deployment for every building in such case. Solution 2: Two building connect to each other based on tunnel which support VLAN function. In this case, only one Service Controller is needed for the entire network.

  11. Layer 3 Network Design Solution_I Building 1 Intranet for staff Ingress VLAN 1 Egress VLAN 10 Client IP subnet 192.168.1.x AD or RADIUS Authentication Allowed access intranet and internet Internet for guest Ingress VLAN 2 Egress VLAN 10 Client IP subnet 192.168.2.x SC Local account HTML-Authentication Building 2 Intranet for staff Ingress VLAN 3 Egress VLAN 10 Client IP subnet 192.168.3.x AD or RADIUS Authentication Allowed access intranet and internet Internet for guest Ingress VLAN 4 Egress VLAN 10 Client IP subnet 192.168.4.x SC Local account HTML-Authentication

  12. Layer 3 Network Solution_I DHCP server Intranet Router Firewall Radius Server Active Directory VLAN 10 & 30 VLAN 20 & 40 Service Controller Egress: VLAN 10 & 20 Ingress: VLAN 1 & 2 Service Controller Egress: VLAN 30 & 40 Ingress: VLAN 3 & 4 VLANSwitch Network: VLAN 10,20 SC Port: VLAN 1, 2, 10, 20 AP Port: VLAN 1,2 VLANSwitch Network: VLAN 30,40 SC Port: VLAN 3, 4, 30, 40 AP Port: VLAN 3,4 Altai AP VLAN 1 VLAN 2 Trunk Port Trunk Port Trunk Port Trunk Port Altai AP VLAN 3 VLAN 4 SSID_Intranet 192.168.1.x VLAN 1 SSID_Intranet 192.168.3.x VLAN 3 SSID_Internet 192.168.2.x VLAN 2 SSID_Internet 192.168.4.x VLAN 4

  13. Layer 3 Solution I Authentication Procedure User User associate with wireless network EAPOL start EAP Response/identity EAP response DHCP request AP EAP Request/identity Redirect the request to Service Controller EAP request EAP success Service Controller In Builing 1 EAP Response/Identity Over AD EAP Response over AD AD Server EAP request over AD EAP success over AD and user configuration DHCP server Response DHCP request Send IP address back Building 1 for example

  41. Altai A3 ACS Solution Deployment scenario: Hotzone whole network solution could be in one box. RADIUS or MAC in the existing network is authentication server, do not need to integrate with Active Director server Can use 3G as backhaul Roaming across A3s is not supported Local database is supported Multiple SSID for different groups of client to access, like staff and guest Each group of client is only allowed to access specific network subnets Different authentication method can be applied to different SSID
