Performance Information Packets for Real-Time Bandwidth Monitoring

The patent implements feedback mechanisms through Performance Information Packets (PIPs) that continuously monitor and report network path performance metrics such as bandwidth availability, jitter, delay, and packet loss. This feedback enables dynamic adjustment of call routing and bandwidth allocation, allowing packet networks to maintain reliable real-time telephony service while preserving network flexibility.

The patent introduces intermediary components including Path Performance Monitors (PPMs) and PIP message brokers that mediate between packet network infrastructure and telephony services. These intermediaries collect performance data from network nodes, process it through standardized protocols, and provide actionable insights for call management, bridging the gap between flexible packet switching and reliable telephony requirements.

The patent creates universal Performance Information Packets that can be transmitted across diverse packet network infrastructures using standardized protocols. These PIPs serve multiple functions simultaneously: monitoring path performance, identifying network congestion, measuring quality metrics, and enabling routing decisions. This multi-functional approach allows simple packet networks to gain comprehensive path state awareness without increasing infrastructure complexity.

The patent transforms unmonitored packet network traffic into observable performance data by introducing measurable parameters through PIPs. These parameters include bandwidth utilization, jitter values, delay measurements, and packet loss rates. By changing the state of network information from invisible to measurable, the patent enables path state awareness while maintaining infrastructure simplicity.

The patent implements dynamic bandwidth management where network resources are continuously adjusted based on real-time performance feedback from PIPs. During periods of network congestion, the system dynamically prioritizes voice traffic over less time-sensitive data, adjusts bandwidth allocation, and modifies routing paths. This dynamic approach allows efficient bandwidth sharing while maintaining voice quality through adaptive resource management.

The patent performs preliminary actions by proactively monitoring network performance metrics before voice quality degradation occurs. PIPs continuously assess bandwidth availability and congestion levels, allowing the system to take preventive measures such as rerouting calls around congested paths or allocating reserved bandwidth before congestion affects voice quality. This proactive approach maintains high network efficiency while preventing quality deterioration.
