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: 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)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.

Package switching network with a deterministic behavior

A process and system for evaluating the deterministic behavior of a packet switching network including subscriber stations connected to each other through at least one switch, the behavior defined as deterministic if any packet sent on the network from a source subscriber station joins the destination subscriber station(s) within a limited time. The process and system determines if each output port from each switch on the network satisfies the relationship: in which: the max latency value is a maximum residence time in an output buffer of a 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 a 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) i is a duration of a longest frame on the virtual link i.

Process and system evaluating deterministic behavior of a packet switching network

The invention relates to a process for checking the deterministic behavior of a packet switching network comprising subscriber stations connected to each other through at least one switch, this behavior being said to be deterministic in the sense that every packet sent on the network from a source subscriber station joins the destination subscriber station(s) within a limited time, characterized in that the following relation is satisfied for each output port on each switch on the network: in which: the max latency value is the maximum residence time in the output buffer of a switch, this value may be different for each switch in the network. BAGi is the minimum time between two consecutive frames belonging to a vertical link i, before they are transmitted on the physical support. (Jitter In) i is the Jitter associated with a virtual link i that represents the time interval between the theoretical instant at which a frame is transmitted, and its effective transmission which may be before or after the theoretical instant. (max frame duration) i is the duration of the longest frame on the virtual link i.

A process for implementing a redundant switched full-duplex Ethernet type communication network including at least two independent elementary networks, each elementary network including at least one source subscriber equipment and at least one destination subscriber equipment, connected to each other through at least one physical link through at least one switch, each equipment being connected to each of these elementary networks. The process performs a frame by frame redundancy on each elementary network.

Redundant switched full-duplex Ethernet type communication network

A switched full-duplex Ethernet type communication network including at least one source subscriber equipment and at least one destination subscriber equipment connected to each other through at least one physical link through at least one switch and at least one virtual link, which is the conceptual representation of a link from a source equipment to at least one destination equipment. Each equipment transmitting Ethernet frames segregates between virtual links and allocation of a passband for each virtual link and multiplexes virtual links on the physical link output from this equipment. Each transmitted frame has a field that identifies the virtual link to which it belongs.
