Cisco Resource Pool Manager Server Service Types

Cisco Resource Pool Manager Server (Cisco RPMS) can support many types of service on the same network access servers (NASes). Each time you add a new customer or service, use one of the following:

Dialed Number Information Service (DNIS) Resource Management, DNIS VPDN Dial Service (Standard Wholesale [VPDN] DNIS)—Uses DNIS numbers (the called telephone numbers) to answer or reject calls based on the configuration in the customer profile. Uses the DNIS number to route the session to the appropriate home gateway.
Default Customer Profile Resource Management, Domain Name VPDN Dial Service (Standard Wholesale Domain Name)—Always answers the calls. Uses the domain name to route the session to the appropriate home gateway.
Default Customer Profile Resource Management, Local authentication, authorization, and accounting (AAA) Dial Service (Standard Retail)—Always answers the call. Uses the local AAA server for authentication.
Default Customer Profile Resource Management, DNIS VPDN Dial Service (Default Customer Profile Wholesale DNIS)—Always answers the call. Uses the DNIS number to route the session to the appropriate home gateway.
DNIS Resource Management, Domain Name VPDN Dial Service (DNIS-Based Wholesale Domain Name)—Uses DNIS numbers to answer or reject calls based on the configuration in the customer profile. Uses the domain name to route the session to the appropriate home gateway.
DNIS Resource Management, Local AAA Dial Service (DNIS-Based Retail)—Uses DNIS numbers to answer or reject calls based on the configuration in the customer profile. Uses the local AAA server for authentication.

Note This chapter describes basic configurations. For detailed planning, see the Cisco Resource Pool Manager Server Solutions Guide.

Standard Wholesale DNIS

Standard wholesale DNIS service uses DNIS numbers to accept or reject a call based on the call type (bearer capability) and session limits before it is answered and to establish VPDN tunnels. For an example of a standard wholesale DNIS configuration, see Figure 2-1.

Figure 2-1: Standard Wholesale DNIS Configuration

Standard wholesale DNIS service is useful for giving each customer or service type separate access numbers and for conserving NAS resources by not answering calls when session limits are reached.

Standard wholesale DNIS service uses the following:

DNIS-based resource management—See the "DNIS-Based Resource Management" section.
DNIS-based VPDN dial service—See the "DNIS VPDN Dial Service" section.

Standard Wholesale Domain Name

Standard wholesale domain name service always answers the call and uses the domain name in the user ID field to build a VPDN tunnel (if the domain name belongs to a VPDN group and is within session limits). Although this service uses more resources by answering all calls, DNIS-based resource management can be difficult to manage and new DNISes will have to be ordered each time you add a customer. For an example of a standard wholesale domain name configuration, see Figure 2-2.

Figure 2-2: Standard Wholesale Domain Name Configuration

Some trunks do not pass DNIS information. If this is true for your configuration, you must use standard wholesale domain name service to build VPDN tunnels.

Standard wholesale domain name service uses the following management methods:

Default customer profile resource management—See the "Default Customer Profile Resource Management" section.
Domain name-based VPDN dial service—See the "Domain Name VPDN Dial Service" section.

Standard Retail

Standard retail service always answers the call and uses the local AAA for user authentication. For an example of a retail configuration, see Figure 2-3.

Figure 2-3: Standard Retail Configuration

Standard retail service uses the following:

Default customer profile resource management—See the "Default Customer Profile Resource Management" section.
Local AAA dial service—See the "Local AAA Dial Service" section.

Default Customer Profile Wholesale DNIS

Default customer profile wholesale DNIS service always answers the call and only uses the DNIS number to build a VPDN tunnel (if the DNIS number belongs to a VPDN group and is within session limits). For an example of an default customer profile wholesale DNIS configuration, see Figure 2-4.

Figure 2-4: Default Customer Profile Wholesale DNIS Configuration

Although default customer profile wholesale DNIS service consumes more resources by always answering calls, you might want to place all of your NASes in a single pool and use VPDN groups for session control.

Default customer profile wholesale DNIS service uses the following:

Default customer profile resource management—See the "Default Customer Profile Resource Management" section.
DNIS-based VPDN dial service—See the "DNIS VPDN Dial Service" section.

DNIS-Based Wholesale Domain Name

DNIS-based wholesale domain name service uses the DNIS number to accept or reject a call based on the session limits and the domain name to establish VPDN tunnels. For an example of a DNIS-based wholesale domain name configuration, see Figure 2-5.

Figure 2-5: DNIS-Based Wholesale Domain Name Configuration

DNIS-based wholesale domain name service works well for sharing smaller resource pools among customers. For example, you could offer levels of service that offered different oversubscription ratios. Session control for each level of service is managed through DNIS numbers and the domain name is used to route each call to the appropriate VPDN tunnel.

DNIS-based wholesale domain name service uses the following:

DNIS-based resource management—See the "DNIS-Based Resource Management" section.
Domain name-based VPDN dial service—See the "Domain Name VPDN Dial Service" section.

DNIS-Based Retail

DNIS-based retail service uses the DNIS number to accept or reject a call based on the call type and session limits before it is answered and uses the local AAA for user authentication. For an example of a DNIS-based retail configuration, see Figure 2-6 .

Figure 2-6: DNIS-Based Retail Configuration

DNIS-based retail works well when you want to create smaller resource pools and ensure that retail customers do not take over the NAS resources.

Standard retail service uses the following:

DNIS-based resource management—See the "DNIS-Based Resource Management" section.
Local AAA dial service—See the "Local AAA Dial Service" section.
