Starent Networks has built its system software on the power of a Linux operating system. The software architecture is highly distributed and designed to provide high availability, flexibility, and performance.
StarOS™
The ST16 and ST40 multimedia core platforms provide software redundancy, scalability, and robust call processing. The StarOS™ operating system achieves this by dividing up the processing into distributed modular software tasks to perform specific functions.
Unlike other solutions that limit processing power for a task to a single card or single processor in the system, the ST16 and ST40 allow the various tasks to take advantage of available processing power throughout the system. By distributing load across all processors in the system, overall performance is significantly improved. This distribution is done automatically without operator intervention, and preserves the single system view (as opposed to conventional bladed architectures) .
Furthermore, distribution of the many tasks limits the impact of process or task failures through fault containment. This ultimately provides a more robust system and significantly reduces subscriber impact.
Key benefits derived from the Starent Networks StarOS™ operating system include:
- Distributed design provides exceptional performance and service protection
- Fault containment significantly limits impact when a fault occurs
- Intra-chassis session recovery ensures a transparent experience for subscribers
- Inter-chassis service recovery adds higher resilience against fiber cuts and loss of power
- Scalability of control and services allows mobile operators to grow solutions capabilities seamlessly
- Integration of key services (In-line Services) provides performance improvements and expenditure savings
- Dynamic hardware removal and insertion keeps the system up-and-running without major impact to subscribers
