In this article, we’ll take a closer look at how the Denovolab Class 4 Fusion softswitch leverages advanced technology to deliver high call throughput and seamless handling, setting a new standard for telecom switching performance.
Harnessing the Power of Parallel Computing
To understand how the Denovolab Class 4 Fusion softswitch achieves its high call rates, it’s essential to examine parallel computing. By leveraging the multiple cores available on a standard x86 server, the Denovolab Class 4 Fusion softswitch distributes tasks across cores, optimizing concurrency to handle an extreme load of calls per second.
- Efficient Task Division: The first step is dividing the workload. Call processing tasks are broken down into independent subtasks that can be processed concurrently. By distributing these tasks across multiple cores, the Denovolab Class 4 Fusion softswitch keeps every core fully utilized, allowing it to manage large call volumes simultaneously.
- Multi-Threading for Concurrent Processing: The Denovolab Class 4 Fusion softswitch’s multi-threaded approach is designed to maximize concurrency. Each thread handles a separate aspect of call processing, such as setup, signaling, and teardown, minimizing dependencies and ensuring the efficient handling of tens of thousands of calls per second.
- Dynamic Load Balancing: The Denovolab Class 4 Fusion softswitch’s load balancer adapts in real-time to keep core utilization optimal. This allows the system to dynamically adjust which cores handle different parts of the call pipeline, further enhancing concurrency and reducing latency.
Maximizing Performance with Assembly Language Optimization
Parallel computing, however, is only part of the equation. The Denovolab Class 4 Fusion softswitch’s impressive performance also relies on low-level assembly language optimization, enabling the softswitch to bypass higher-level code overhead and operate with minimal latency.
- Direct Hardware Control: Assembly language provides the precision necessary to control CPU registers, memory, and instructions directly. The Denovolab Class 4 Fusion softswitch uses assembly to minimize cycles per operation, allowing the software to achieve extreme processing speeds crucial for high call volumes.
- Atomic Operations for Data Integrity: Through atomic operations, the Denovolab Class 4 Fusion softswitch can handle shared data without costly locking mechanisms. This allows it to increment call counters, manage state, and update statistics concurrently without slowing down call handling.
- Memory Optimization: Assembly enables fine-grained control over memory access, allowing the Denovolab Class 4 Fusion softswitch to optimize data placement to prevent cache misses and maximize data throughput. This optimization is essential when managing high-frequency call routing and egress termination.
- SIMD for Parallel Data Processing: The Denovolab Class 4 Fusion softswitch uses SIMD (Single Instruction, Multiple Data) instructions to process data-heavy tasks, allowing the same instruction to handle multiple data points at once. This data-level parallelism is crucial for handling the thousands of simultaneous operations required for high call throughput.
Handling 10,000 Calls per Second Ingress and 20,000 Calls per Second Egress
The Denovolab Class 4 Fusion softswitch can manage an impressive 10,000 calls per second on the ingress side and 20,000 calls per second on the egress side, all on a single x86 server.
Ingress Call Handling
- Dedicated Core Allocation: The Denovolab Class 4 Fusion softswitch allocates cores specifically to handle the high ingress load, processing calls with minimal delay. Each call setup involves a streamlined sequence of atomic operations, reducing the setup time and allowing thousands of concurrent connections.
- Optimized Signaling Protocols: Assembly-level optimizations allow the Denovolab Class 4 Fusion softswitch to manage SIP messages at high speeds, ensuring efficient call establishment even under heavy load.
Egress Call Handling
- High Parallelization: The Denovolab Class 4 Fusion softswitch’s egress system uses parallel processing across multiple cores to handle outgoing call completions. By spreading egress tasks across cores, the Denovolab Class 4 Fusion softswitch achieves exceptional scalability without bottlenecks.
- Batch Processing and Non-blocking I/O: The system employs batch processing and non-blocking I/O to manage high call termination rates without tying up resources waiting for network responses, critical for maintaining throughput at scale.
Real-World Impact: Unparalleled Performance and Reliability
The Denovolab Class 4 Fusion softswitch’s architecture enables telecom providers to handle massive call volumes on standard hardware, meeting both performance and reliability demands. The ability to manage high calls per second on egress without requiring high-end hardware translates into substantial cost savings while delivering outstanding performance.
For telecom providers, the Denovolab Class 4 Fusion softswitch’s architecture means fewer hardware resources, lower energy costs, and the flexibility to handle high traffic loads. With this combination of parallel computing, assembly-level control, and robust load management, the Denovolab Class 4 Fusion softswitch redefines what’s possible in high-performance telecom switching.
Conclusion
The Denovolab Class 4 Fusion softswitch leverages the full potential of parallel computing and assembly optimization to deliver extreme call-handling capabilities on a single x86 server. With the ability to handle extremely high CPS, the Denovolab Class 4 Fusion softswitch is a leader in high-performance telecom infrastructure. This powerful, scalable solution is an ideal choice for providers looking to maximize throughput and efficiency without sacrificing cost-effectiveness.
