Managing Subscribers

The SCE platform is subscriber aware, that is, it can relate traffic and usage to specific customers. This ability to map between IP flows and a specific subscriber allows the system to do the following:

•Maintain the state of each subscriber transmitting traffic through the platform

•Provide usage information for specific subscribers

•Enforce the appropriate policy on subscriber traffic (each subscriber can have a different policy)

•Information About Subscribers

•Importing and Exporting Subscriber Information

•Removing Subscribers and Templates

•Importing and Exporting Anonymous Groups

•Monitoring Subscribers

•Configuring Subscriber Aging

•Configuring the SCE Platform/SM Connection

What is a Subscriber?

In the Service Control solution, a subscriber is defined as a managed entity on the subscriber side of the SCE Platform to which accounting and policy are applied individually.

The following table lists several examples of subscribers in Service Control solutions.

Subscriber Modes in Service Control Solutions

Service Control solutions support several modes of handling subscribers:

•Subscriber-less mode

•Anonymous subscriber mode

•Static subscriber aware mode

•Dynamic subscriber aware mode

Note Not all the Service Control solutions support all modes.

The most basic mode is Subscriber-less mode. In this mode, there is no notion of subscriber in the system, and the entire link where the SCE platform is deployed is treated as a single subscriber. Global Application level analysis (such as total p2p, browsing) can be conducted, as well as global control (such as limiting total p2p to a specified percentage). From a configuration stand point, this is a turnkey system and there is no need to integrate or configure the system from a subscriber perspective.

In Anonymous subscriber mode, analysis is performed on an incoming network ID (IP address), as the SCE platform creates an 'anonymous/on-the-fly' record for each subscriber. This permits analyzing traffic at an individual network ID level (for example, to identify/monitor what a particular 'subscriber' IP is currently doing) as well as control at this level (for example, to limit each subscriber's bandwidth to a specified amount, or block, or redirect). Anonymous-subscriber allows quick visibility into application and protocol usage without OSS integration, and permits the application of a uniform control scheme using predefined templates.

There are two possible Subscriber Aware modes. In these modes, subscriber IDs and currently used network IDs are provisioned into the SCE platform. The SCE platform can then bind usage to a particular subscriber, and enforce per-subscriber policies on the traffic. Named reports are supported (such as top subscribers with the OSS IDs), quota-tracking (such as tracking a subscriber-quota over time even when network IDs change) as well as dynamic binding of packages to subscribers. The two Subscriber Aware modes are:

•Static subscriber aware — The network IDs are static. The system supports the definition of static-subscribers directly to the SCE platform. This is achieved by using the SCE platform CLI, and defining the list of subscribers, their network IDs and policy information using interactive configuration or import/export operations.

•Dynamic subscriber aware — The network IDs change dynamically for each subscriber login into the Service Provider's network. In this case, subscriber awareness is achieved by integrating with external provisioning systems (either directly or through the SM) to dynamically learn network-ID to subscriber mappings, and distribute them to the SCE platforms.

Subscriber Mapping Limits

Refer to the following table for the maximum number of IP mappings permitted per single subscriber. An IP mapping may be either a single IP address or a range of addresses.

Aging Subscribers

Subscribers can be aged automatically by the SCE platform. `Aging' is the automatic removal of a subscriber, performed when no traffic sessions assigned to it have been detected for a certain amount of time. The most common usage for aging is for anonymous subscribers, since this is the easiest way to ensure that anonymous subscribers that have logged-out of the network are removed from the SCE platform and are no longer occupying resources. Aging time can be configured individually for introduced subscribers and for anonymous subscribers.

Synchronizing Subscriber Information in a Cascade System

In a hot standby, cascade setup with full redundancy, the external provisioning server updates only the active SCE platform. However, the standby SCE platform must always be updated with the latest subscriber-related information (login, logout). This is required to minimize information loss in case of fail-over. In general, the only entity that is allowed to change subscriber information in the standby SCE platform is the active SCE platform. The standby SCE platform does not accept any subscriber operations (it returns a STANDBY_VIOLATION error instead), and it also does not generate any asynchronous subscriber notifications (such as pull-response or logout-notification).

There are only two exceptions to this rule:

•Standby SCE platform can change subscriber information of the default subscriber.

•Standby SCE platform can perform subscriber aging

Therefore, when working as a pair, the active SCE platform constantly updates the standby SCE platform with external data information. In addition, the standby SCE platform constantly requests external data information from the active SCE platform. The synchronization is bi-directional to ensure that the subscriber databases in both SCE platforms are identical.

Note The external data is only relevant for introduced subscribers (both static and dynamic). It has no meaning for anonymous subscribers or the default subscriber. No more than two minutes of external data information will be lost by the standby SCE platform if a fail-over occurs.

The following subscriber information is considered as external data:

•subscriber name

•IP mappings

•tunables

•manager name

•aging time

•lease time

•is-static flag

Only the active SCE platform communicates with the SM. The SM is aware of the active/standby state of each SCE platform, and is also aware of a fail-over.

Specifically, this means the following:

•In push mode, the SM pushes events to the active SCE platform, which updates the standby SCE platform.

•In pull mode, only the active SCE platform pulls subscribers from the SM.

•The standby SCE platform can create anonymous subscribers based on the updates received from the active SCE platform, but does not generate pull-response for them.

•If SCE-SM connection failure, the SM handles the SCE recovery of the active SCE platform only. The active SCE platform propagates the information to the standby SCE platform.

Anonymous Groups and Subscriber Templates

An anonymous group is a specified IP range, possibly assigned a subscriber template. When an anonymous group is configured, the SCE platform generates anonymous subscribers for that group when it detects traffic with an IP address that is in the specified IP range. If a subscriber template has been assigned to the group, the anonymous subscribers generated have properties as defined by that template. If no subscriber template has been assigned, the default template is used.

The SCE platform can support a maximum of 1000 anonymous groups. Subscriber templates are identified by a number from 0-199.

Subscriber templates 1-199 are defined in csv formatted subscriber template files. However, template #0 cannot change; it always contains the default values.

If an anonymous group is not explicitly assigned a template, the group uses template #0.

Subscriber Files

•Subscriber default csv file format

•Subscriber anonymous groups csv file format

Individual subscribers, anonymous groups, and subscriber templates may all be defined in csv files. A csv file is a text file in a comma-separated-values format. Microsoft Excel™ can be used to view and create such files. The subscriber data is imported into the system using the appropriate CLI command. The SCE platform can also export the currently configured subscribers, subscriber templates and anonymous groups to csv-formatted files.

Subscriber csv files and subscriber template csv files are application-specific. Refer to the relevant application documentation for the definition of the file format.

Each line in a csv file should contain either a comment (beginning with the character `#'), or a list of comma-separated fields.

Subscriber csv files are application-specific, but a default format is defined by the SCE, which is used when the application does not choose to over-ride it. The application might over-ride the format when additional data is desired for each subscriber or subscriber template. Refer to the relevant Service Control Application documentation to see if the application defines a different format.

Subscriber template csv files are application-specific. Refer to the relevant Service Control Application documentation of the file format.

Anonymous groups csv files are not application specific. Their format is described below.

Subscriber default csv file format

Each line has the following structure:

name, mappings, packageId

•Name — is the subscriber name

•Mappings — contains one or more mappings, specifying the Tunnel IDs or IP addresses mapped to this subscriber. Multiple mappings are separated by semi-colon. Tunnel IDs and IP address/range cannot be specified for the same subscriber. The following mapping formats are supported:

–IP address — in dotted decimal notation. Example: 10.3.4.5

–IP address range — dotted decimal, followed by the amount of significant bits.

Note The non-significant bits (as determined by the mask) must be set to zero. Example: 10.3.0.0/16. Example for a bad range: 10.1.1.1/24 (Should be 10.1.1.0/24).

•packageId — the ID of the package to which the subscriber is assigned

Here is an example of a subscriber csv file in the default format:

# A comment line 
sub7, 10.1.7.0/24, 1 
sub8, 10.1.11.32, 1 
sub9, 10.2.22.10, 2 
sub10, 10.3.33.10, 2 
sub11, 10.4.44.10, 1 
sub12, 10.1.11.90; 10.3.0.0/16, 2

Subscriber anonymous groups csv file format

Each line has the following structure:

name, IP-range, template-index, manager-name (optional)

•name — is the anonymous group name

•IP-range — dotted decimal, followed by the amount of significant bits. Example: 10.3.0.0/16

•template-index — is the index of the subscriber template to be used by subscribers belonging to this anonymous group.

•manager-name (optional) — is either SM or the name of the SCMP peer. Use "SM" to pull subscribers from the SM (if it exists). If not specified, "SM" is assumed.

Here is an example of an anonymous groups csv file:

# Yet another comment line 
anon1, 10.1.1.0/24, 1, 1 
anon2, 10.1.2.0/24, 2, 2 
anon3, 10.1.3.0/32, 3, 3 
anon4, 10.1.4.0/24, 3, 3 
anon5, 10.1.5.0/31, 2 
anon6, 10.1.6.0/30, 1 
anon7, 0.0.0.0/0, 1

Configuring the SCE Platform/SM Connection

•Configuring the Behavior of the SCE Platform in Case of Failure of the SM

•Configuring the SM-SCE Platform Connection Timeout

The user can configure the behavior of the SCE platform in case of failure of the Subscriber Manager (SM):

•If SM functionality is critical to the operation of the system — configure the desired behavior of the SCE platform if any loss of connection with the SM (may be due either to failure of the SM or failure of the connection itself).

•If SM functionality is not critical to the operation of the system — no action needs to be configured In this case you can specify that the system operational-status of the SCE platform should be 'warning' when the link is down.

Configuring the Behavior of the SCE Platform in Case of Failure of the SM

Options

The following options are available:

•action—The specified action will be performed in case of loss of connection between the SCE platform and the SM.

Possible actions are:

–force-failure — Force failure of SCE platform. The SCE platform then acts according to the behavior configured for the failure state.

–remove-mappings — Remove all current subscriber mappings.

–shut — The SCE platform shuts down and quits providing service.

–none (default) — Take no action.

•warning—The system operational-status of the SCE platform should be 'warning' in case of loss of connection between the SCE platform and the SM. No action is taken.

To specify the action that the SCE platform will perform if the SCE-SM connection fails, use this command.

Step 1 From the SCE(config if)# prompt, type subscriber sm-connection-failure action [force-failure|none|remove-mappings|shut] and press Enter.

To specify that the system operational-status of the SCE platform should be 'warning' if the SCE-SM connection fails, use this command.

Step 1 From the SCE(config if)# prompt, type subscriber sm-connection-failure warning and press Enter.

Configuring the SM-SCE Platform Connection Timeout

You can also configure the timeout interval; the length of time that the SM-SCE platform connection is disrupted before a failed connection is recognized and the configured behavior is applied.

Options

The following option is available:

•interval — the timeout interval in seconds

Step 1 From the SCE(config if)# prompt, type subscriber sm-connection-failure timeout interval and press Enter.

Configures the connection timeout.
