When realizing
pipeline forwarding Pipeline forwarding (PF) applies to packet forwarding in computer networks the basic concept of '' pipelining'', which has been widely and successfully used in computing — specifically, in the architecture of all major central processing units ...
a predefined schedule for forwarding a pre-allocated amount of bytes during one or more
time frames
''Time Frames'' is a 2021 album by Michael Waldrop, his third release with Origin Records. The recording is a crossover from classical to new music, jazz, minimalism and world music. The album was chosen for the 2021 AllMusic Guide Top 50 List of ...
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
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 In Telecommunication and Computer networking, time-driven switching (TDS) is a node by node time variant implementation of Circuit switching, where the propagating datagram is shorter in space than the distance between source and destination. With T ...

and
