▀ Features and Functionality - Base Software

16,000 SGSN Support

With growing roaming agreements, many more GPRS/UMTS networks support certain APNs and therefore the number

of SGSNs that could connect to the GGSN increases. This feature increases the number of connected SGSNs thereby

allowing a single GGSN service to support a much larger roaming network.

The GGSN service supports a maximum of 16,000 SGSN IP addresses. The chassis limit for bulk statistics collection is

also limit to 16,000. No change in configuration is needed to support this feature.

AAA Server Groups

Value-added feature to enable VPN service provisioning for enterprise or MVNO customers. Enables each corporate

customer to maintain its own AAA servers with its own unique configurable parameters and custom dictionaries.

This feature provides support for up to 800 AAA (RADIUS and Diameter) server groups and 800 NAS IP addresses that

can be provisioned within a single context or across the entire chassis. A total of 128 servers can be assigned to an

individual server group. Up to 1,600 accounting, authentication and/or mediation servers are supported per chassis and

may be distributed across a maximum of 1,000 APNs. This feature also enables the AAA servers to be distributed across

multiple APN within the same context.

processing cards.

Access Control List Support

Access Control Lists provide a mechanism for controlling (i.e permitting, denying, redirecting, etc.) packets in and out

of the system.

IP access lists, or Access Control Lists (ACLs) as they are commonly referred to, are used to control the flow of packets

into and out of the system. They are configured on a per-context basis and consist of ―rules‖ (ACL rules) or filters that

control the action taken on packets that match the filter criteria

Once configured, an ACL can be applied to any of the following:

An individual interface

All traffic facilitated by a context (known as a policy ACL)

An individual subscriber

All subscriber sessions facilitated by a specific context
