DSC Features

Out of the box the SVI_DSC offers a range of powerful features to insure successful deployment in your Diameter Network:

Intelligent Routing

diameter routingExtensive intelligent routing options are available on the SVI-DSC:

  • Route on header and AVP contents
  • Full support for RFC 3588
  • Full support for session bindings
  • Support for Subscriber Location Function - 3GPP TS29.228
  • White List / Black List Admission Control
  • White List /Black list of supported AVP's
  • QoS

To ease network integration routing can first be performed offline to test new routing rules. These tests are configured in XML allowing a suite of backward compatibility tests to be developed.

Diameter Manipulation Engine

DSC manipulationAs with all SVI products the SVI-DSC comes out of the box with a powerful, regular-expression based manipulation engine allowing all parts of a Diameter message / AVP to be created, replaced or removed. This insures full inter-op between different vendors / devices and comprehensive message normalisation. As with the routing engine message formats can be tested offline by creating messages manually or loading pcaps from Wireshark.

Telephony Application Server
