A system and method for collision detection and avoidance that converts a probabilistic, packet based communications system into a deterministic packet based communications system. The system and method operates in packet, frame, or datagram based network environments that support different levels of forwarding priority, for example, IP networks and Ethernet networks.

A software and hardware system that provides for per flow guaranteed throughput and goodput for packet data flows using network transport protocols that have window-based flow control mechanisms or TCP-friendly flow control mechanisms. The system and method for guaranteed throughput of individual flows in turn enables a method for provisioning link bandwidth among multiple flows and provisioning network throughput and goodput at the granularity of individual flows. The invention also eliminates Layer 3 packet drops for a data flow using window-based flow control or TCP-friendly flow control, which in turn obviates congestion collapse and quality collapse scenarios.
