Package switching network with a deterministic behavior

摘要

A packet switching network including subscriber stations connected to each other through at least one switch, which has a behavior defined as deterministic in that any packet sent on the network from a source subscriber station joins the destination subscriber station(s) within a limited time. In the packet switching network each output port from each switch on the network satisfies the relationship: $\sum _{i\mathrm{number}\mathrm{of}\mathrm{virtual}\mathrm{links}\mathrm{passing}\mathrm{through}\mathrm{the}\mathrm{buffer}}[1+\mathrm{int}\left(\frac{{\left(\mathrm{Jitter}\mathrm{In}\right)}_i+\max \mathrm{Latency}}{\mathrm{BAGi}}\right)]*\left(\max \mathrm{frame}\mathrm{duration}\right)<=\mathrm{latency}$ in which: the max latency value is a maximum residence time in an output buffer of the at least one switch, this value may be different for each switch in the network, BAGi is a minimum time between two consecutive frames belonging to a virtual link i, before they are transmitted, (Jitter In)_i is Jitter associated with the virtual link i that represents a time interval between a theoretical instant at which a frame is transmitted, and its effective transmission that may be before or after the theoretical instant, and (max frame duration) is a duration of a longest frame on the virtual link i.
