Captive Portal System
Wireless Hotspots * Wired Networks * Device Authentication
Now avaliable for the Linux platform
Captive portals provide a convenient method of controlling access to public and private networks leveraging existing
web technologies. Users simply "plug-in" open their favorite browser and follow on-screen prompting to logon to the network.
The main benefits of this solution come from not requiring additional customer knowledge, software or special configuration.
Clients are able to quickly and easily gain access to the network regardless of the type of device or operating system used.
While the captive portals primary purpose is authentication they provide additional benefits such as the ability to direct
new users to begin a sign-up process, fund an existing account or provide complimentary limited access to select services such
as a company web site or information related to a particular venue.
Air Marshal is uniquely suitable for a wide range of environments including
hotels, ISPs, universities, Internet HotSpots and guest networks. Comprehensive standards based RADIUS AAA support enables
Air Marshal to seamlessly integrate with existing standards based billing and management platforms such as Emerald.
|> > RADIUS/AAA Features
|RADIUS Authentication of User credentials and Device/MAC address
||Compatibility with existing Authentication and Billing Systems, centralized management, participate in international roaming networks.
|RADIUS Accounting - detailed logging of IP, MAC, time and data usage, disconnect reason, etc.
||Accounting data is useful for a wide array of tasks such as usage billing, enforcement of data and
time limits, managing concurrent access, capacity planning, auditing and troubleshooting.
|Interim Accounting status updates
||Provides scheduled session status updates to the central management system verifying the session and
providing current data usage statistics for dynamic session management.
|RFC3576 Mid-Session Disconnect
||Allows a central management system to disconnect active sessions when the session is no longer
authorized to access network services.
|Change of Authorization (CoA)
||Allows a central management system to dynamically change authorization parameters of an active user session such as a bandwidth allocation without the need
to disconnect the user.
|Periodic Session Reauthorization
||Enables Air Marshal to periodically check the authorization status of each session and disconnect sessions no longer allowed access.
|Ascend Binary Data Filter VSAs
||Ascend filters provide IP filtering rules limiting the range of network access on a per session basis. Commonly used to filter SMTP traffic
in roaming networks to curb abuse.
|MAC based Device Pre-Authentication
||Authorized client devices can be authenticated automatically saving the user the need to manually enter an access login and password.
|WISPr Location, Redirect, Bandwidth control and Session limiting VSAs
||Enables RADIUS authorization to control bandwidth allocation, data usage limits and customized redirect URLs
|Startup device reboot indication
||Provides management system notifications when Air Marshal is started to properly recover from unexpected failures such as a power outage.
|Support for Backup RADIUS authentication and accounting servers
||An unlimited number of backup servers are supported for Authentication and Accounting purposes to prevent RADIUS server failure from effecting network access.
|> > Network & Session Features
|Layer 3 IP Routing
||This mode allows Air Marshal to control network access by routing managed IP subnets through it.
|Private Address / NAT services
||NAT mode enables a single IP address to be used to provide network access to multiple clients.
|Layer 2 transparent bridging
||Bridge mode allows Air Marshal to be seemlessly "plugged-in" to an existing network providing authentication services typically with no
external configuration changes on the network.
|TCP & UDP device authentication listeners
||Air Marshal is able to detect and authenticate server devices and non-web based WiFi systems such as Nintendo DS.
|IP or network layer session tracking
||Prevents abuse, determine if and how long users are active. Air Marshal can be placed on the same physical network (recommended) or placed behind an IP router.
|Multiple networks and interfaces
||A single Air Marshal server supports multiple managed subnets and network interfaces.
|> > Air Marshal General Features
|Single server supports thousands of concurrent sessions
||Optimize large scale deployments
|Browser based password encryption
||Provides increased logon password security in addition to SSL encryption
||Industry standard for encryption and mutual authentication. Establishes identity, protects
sensitive client information such as account passwords.
|Configurable Web HTML interface
||Customize the look and feel, link to sign-up server, account management and advertising sites
|User status display
||Allows users to view account statistics such as time and data used and remaining.
|Integrated ADMIN interface
||Easy to use 100% web based configuration and local account management simplifies system configuration tasks.
|Active session list
||See who's online including duration and real-time bandwidth usage. Enables disconnect of active sessions.
|Setup a walled garden
||Provides complimentary limited access to select services such as new customer signup, account management,
company web sites or information related to a particular venue.
||Offer customized login portals based on user location, language, browser and device type. Operate multiple specialized venues concurrently
on single server instance.
|Local account management
||Configure local access accounts with expiration date, time & data limits and maximum upload/download data rates.
Useful for smaller installations or special administrative access.
||Provides guest access to the network with an optional set of
limitations such as upload/download data rates and daily time and data usage restrictions. This is useful in situations
where you may want to provide a certain level of free service such as one or two hours of service
per day, offer advertising supported access or simply require users read and accept a terms of
service agreement before gaining access to the network.
|Client Data Mirroring
||Captures all network data sent or received on per user basis to industry standard capture files. Useful for diagnostic or intercept purposes.
|Transparent web proxy
||Directs HTTP requests to local transparent proxy servers on a per user basis. Enables customer choice of acceleration and content filtering services.
|Maximum prioritized UL/DL data rates per user
||Prevents single users from monopolizing network resources. Enables tiered service offerings.
||Restrict groups of users to common shared bandwidth allocations. Prevents single users from monopolizing network resources. Enables tiered service offerings.
|Commercial session interruption
||Periodically force users to view a series of commercial messages. Advertising supported access. Tiered service offerings.
|iPass smart client
||Roaming to iPass network via native smart client on PCs and mobile devices.
