a predefined schedule for forwarding a pre-allocated amount of bytes during one or more [[pipeline forwarding#Operating principles|time frames]] along a path of subsequent switches establishes a '''synchronous virtual pipe''' (SVP). The SVP capacity is determined by the total number of bits allocated in every [[pipeline forwarding|time cycle]] for the SVP. For example, for a 10 ms time cycle, if 20,000 bits are allocated during each of 2 time frames, the SVP capacity is 4 Mbit/s.

Pipeline forwarding guarantees that reserved traffic, i.e., traveling on an SVP, experiences:

# bounded end-to-end delay,
# delay jitter lower than two TFs, and
# no congestion and resulting losses.

Two implementations of the pipeline forwarding were proposed: [[time-driven switching]] (TDS) <ref>{{Citation
