Abstract: 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.

Abstract: This invention describes a switched full-duplex Ethernet type communication network comprising at least one source subscriber equipment (13) and at least one destination subscriber equipment (14) connected to each other through at least one physical link through at least one switch and at least one virtual link (VL), which is the conceptual representation of a link from a source equipment (13) to at least one destination equipment (14), in which each equipment transmitting Ethernet frames comprises:

Abstract: 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: 1 i ⁢   ⁢ number ⁢   ⁢ of ⁢   ⁢ virtual ⁢   ⁢ links passing ⁢   ⁢ through ⁢   ⁢ the ⁢   ⁢ buffer   ⁢ [ 1 + int ( ( Jitter ⁢   ⁢ In ) i ⁢ i + max ⁢   ⁢ Latency BAGi ) ] * ( max ⁢   ⁢ frame ⁢   ⁢ duration ) ≤ max ⁢   ⁢ latency

Abstract: The invention relates to a process for implementation of a redundant switched full-duplex Ethernet type communication network comprising at least two independent elementary networks, each elementary network (RE1, RE2) comprising 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 (RE1, RE2) in which a frame by frame redundancy is made on each elementary network.
