Trillium | GPRS Network Service (NS)
Description
The General Packet Radio Service (GPRS) Network Service (NS) portable software product provides message transport along the signaling and data planes between the Base Station System (BSS) and the Serving GPRS Support Node (SGSN) over a Frame Relay carrier network. The main functions of NS are to:
- Create BSSGP (NS user) Virtual Connections (BVCs)
- Create Network Service Virtual Connections (NSVCs) over the Frame Relay network
- Share the BVC traffic load over the associated NSVCs
- Distribute the load upon NSVC failure and recovery
- Provide congestion indications to the BSSGP layer
- Manage procedures on NSVCs
Trillium NS software enables telecom equipment manufacturers of soft switches, signaling gateways, signal transfer points, service control points, media gateway controllers or other products to:
- Accelerate time to market
- Reduce development costs
- Reduce project risk of internally developed NS applications
Product deliverables consist of C source software, documentation, training, a warranty and technical support.
Features + Benefits
- Distributes Protocol Data Units (PDUs) from its user over multiple NSVCs. This distribution ensures in-sequence delivery during normal operation.
- Insulates the service user from NSVC failures. The failure and recovery of an NSVC is hidden from the service user.
- Periodically tests for failure the state of each NSVC.
- Deactivates (blocks) the failed NSVC upon detecting an NSVC failure. The traffic assigned to the failed NSVC is redistributed among the remaining operational NSVCs to provide continuous service to the service user.
- Redistributes user traffic to use the new NSVC upon recovery of a failed NSVC or introduction of a new NSVC into the system. The new NSVC provides greater bandwidth to the service user.
- Indicates NSVC congestion to the service user.
- Operates in both BSS and SGSN environments.
- Supports a dynamic BVC learning option for SGSN.
- Distributes on multiple processor boards.
- Routes incoming traffic on a set of BVCs to a designated BSSGP user instance.
- Interfaces with multiple Frame Relay Q.922 layer instances on a per physical link basis.
- Conforms to Trillium Advanced Portability Architecture (TAPA)
- Benefits of licensing Trillium software from Continuous Computing
