AI Technical Summary

Technical Problem

Traditional SIP communication engines are prone to concurrent deadlocks when handling high-concurrency signaling, lack flow control capabilities at the serialization processor granularity, and heartbeat probe messages share the same scheduling path with core service signaling, resulting in a decline in system performance.

Method used

Session affinity routing is implemented using a cascaded hash algorithm. A fixed-capacity serialization processor object pool is constructed. Combined with overload protection of the global task processing thread pool and source rate limiting at the transport layer, bypass direct scheduling of heartbeat probe packets is implemented.

Benefits of technology

It eliminates the possibility of concurrent deadlock, enables fine-grained flow control and efficient distribution of business traffic, and improves system stability and throughput.

Abstract

This invention discloses a method, system, computer device, and storage medium for concurrent distribution and scheduling of SIP signaling and multi-level overload protection. The method includes: step S1, constructing a fixed-capacity serialization processor object pool; step S2, implementing session affinity routing based on a concatenated hash algorithm and obtaining hash routing results; step S3, implementing overload protection for the global task processing thread pool and backpressure based on the SIP 503 protocol; and step S4, implementing deep detection of the serialization processor task queue and source rate limiting at the transport layer. This method can eliminate concurrent deadlock at the architectural level, achieve multi-level adaptive overload protection, and perform SIP signaling distribution and scheduling of service traffic.
